The Sustainable Development Goals (SDGs) or Global Goals are a collection of 17 interlinked global goals designed to be a "shared blueprint for peace and prosperity for people and the planet, now and into the future". The SDGs were set up in 2015 by the United Nations General Assembly (UN-GA) and are intended to be achieved by 2030. They are included in a UN-GA Resolution called the 2030 Agenda or what is colloquially known as Agenda 2030. The SDGs were developed in the Post-2015 Development Agenda as the future global development framework to succeed the Millennium Development Goals which were ended in 2015. The SDGs emphasize the interconnected environmental, social and economic aspects of sustainable development, by putting sustainability at their center.

The 17 SDGs are: No poverty, zero hunger, good health and well-being, quality education, gender equality, clean water and sanitation, affordable and clean energy, decent work and economic growth, industry, innovation and infrastructure, Reduced Inequality, Sustainable Cities and Communities, Responsible Consumption and Production, Climate Action, Life Below Water, Life On Land, Peace, Justice, and Strong Institutions, Partnerships for the Goals. Though the goals are broad and interdependent, two years later (6 July 2017), the SDGs were made more "actionable" by a UN Resolution adopted by the General Assembly. The resolution identifies specific targets for each goal, along with indicators that are being used to measure progress toward each target. The year by which the target is meant to be achieved is usually between 2020 and 2030. For some of the targets, no end date is given.

There are cross-cutting issues and synergies between the different goals. Cross-cutting issues include gender equality, education, culture and health. With regards to SDG 13 on climate action, the IPCC sees robust synergies, particularly for the SDGs 3 (health), 7 (clean energy), 11 (cities and communities), 12 (responsible consumption and production) and 14 (oceans). Synergies amongst the SDGs are "the good antagonists of trade-offs". Some of the known and much discussed conceptual problem areas of the SDGs include: The fact that there are competing and too many goals (resulting in problems of trade-offs), that they are weak on environmental sustainability and that there are difficulties with tracking qualitative indicators. For example, these are two difficult trade-offs to consider: "How can ending hunger be reconciled with environmental sustainability? (SDG targets 2.3 and 15.2) How can economic growth be reconciled with environmental sustainability? (SDG targets 9.2 and 9.4) "

The UN High-Level Political Forum on Sustainable Development (HLPF) is the annual space for global monitoring of the SDGs, under the auspices of the United Nations Economic and Social Council. However, it has so far failed to act as an orchestrator to promote system-wide coherence due to a lack of political leadership owing to divergent national interests. To facilitate monitoring of progress on the SDG implementation, a variety of tools exist to track and visualize this progress towards the goals. All intention is to make data more available and easily understood. For example, the "SDG Tracker", launched in June 2018, presents available data across all indicators. There were serious impacts and implications of the COVID-19 pandemic on all 17 SDGs in the year 2020. A scientific assessment released in 2022 stated that the world is not on track to achieve the SDGs by 2030 and concluded that the SDGs have so far had only limited political effects in global, national and local governance since their launch in 2015.

On 25 September 2015, the 193 countries of the UN General Assembly adopted the 2030 Development Agenda titled "Transforming our world: the 2030 Agenda for Sustainable Development". This agenda has 92 paragraphs. Paragraph 59 outlines the 17 Sustainable Development Goals and the associated 169 targets and 232 indicators.

The SDGs were an outcome from a UN conference that was not criticized by any major non-governmental organization (NGO). Instead, the SDGs received broad support from many NGOs.

Structure of goals, targets and indicators

The lists of targets and indicators for each of the 17 SDGs was published in a UN resolution in July 2017. Each goal typically has 8–12 targets, and each target has between one and four indicators used to measure progress toward reaching the targets. The targets are either "outcome" targets (circumstances to be attained) or "means of implementation" targets. The latter targets were introduced late in the process of negotiating the SDGs to address the concern of some Member States about how the SDGs were to be achieved. Goal 17 is wholly about how the SDGs will be achieved.

The numbering system of targets is as follows: "Outcome targets" use numbers, whereas "means of implementation targets" use lower case letters. For example, SDG 6 has a total of 8 targets. The first six are outcome targets and are labeled Targets 6.1 to 6.6. The final two targets are "means of implementation targets" and are labeled as Targets 6.a and 6.b.

The United Nations Statistics Division (UNSD) website provides a current official indicator list which includes all updates until the 51st session Statistical Commission in March 2020.

The indicators were classified into three tiers based on their level of methodological development and the availability of data at the global level. Tier 1 and Tier 2 are indicators that are conceptually clear, have an internationally established methodology, and data are regularly produced by at least some countries. Tier 3 indicators had no internationally established methodology or standards. The global indicator framework was adjusted so that Tier 3 indicators were either abandoned, replaced or refined. As of 17 July 2020, there were 231 unique indicators.

Reviews of indicators

The indicator framework was comprehensively reviewed at the 51st session of the United Nations Statistical Commission in 2020. It will be reviewed again in 2025. At the 51st session of the Statistical Commission (held in New York City from 3–6 March 2020) a total of 36 changes to the global indicator framework were proposed for the Commission's consideration. Some indicators were replaced, revised or deleted. Between 15 October 2018 and 17 April 2020, other changes were made to the indicators. Yet their measurement continues to be fraught with difficulties.

Listing of 17 goals with their targets and indicators

Many goals build on existing agreements and are integral parts of other political processes, such as international agreements on biodiversity, climate, oceans or standards and programs set by the International Labour Organization, the World Health Organization and so forth.

Goal 1: No poverty

SDG 1 is to: "End poverty in all its forms everywhere". Achieving SDG 1 would end extreme poverty globally by 2030. A study published in September 2020 found that poverty increased by 7 per cent in just a few months due to the COVID-19 pandemic, even though it had been steadily decreasing for the last 20 years.

The goal has seven targets and 13 indicators to measure progress. The five "outcome targets" are: eradication of extreme poverty; reduction of all poverty by half; implementation of social protection systems; ensuring equal rights to ownership, basic services, technology and economic resources; and the building of resilience to environmental, economic and social disasters. The two targets related to "means of achieving" SDG 1 are mobilization of resources to end poverty; and the establishment of poverty eradication policy frameworks at all levels.

Despite the ongoing progress, 10 percent of the world's population live in poverty and struggle to meet basic needs such as health, education, and access to water and sanitation. Extreme poverty remains prevalent in low-income countries, particularly those affected by conflict and political upheaval. In 2015, more than half of the world's 736 million people living in extreme poverty lived in Sub-Saharan Africa. Without a significant shift in social policy, extreme poverty will dramatically increase by 2030. The rural poverty rate stands at 17.2 percent and 5.3 percent in urban areas (in 2016).[29] Nearly half are children.

Goal 2: Zero hunger (No hunger)

Sufficient and healthy foods should be made available to everyone

SDG 2 is to: "End hunger, achieve food security and improved nutrition, and promote sustainable agriculture". Globally, 1 in 9 people are undernourished, the vast majority of whom live in developing countries. Under nutrition causes wasting or severe wasting of 52 million children worldwide. It contributes to nearly half (45%) of deaths in children under five – 3.1 million children per year.

SDG 2 has eight targets and 14 indicators to measure progress. The five "outcome targets" are: ending hunger and improving access to food; ending all forms of malnutrition; agricultural productivity; sustainable food production systems and resilient agricultural practices; and genetic diversity of seeds, cultivated plants and farmed and domesticated animals; investments, research and technology. The three "means of achieving" targets include: addressing trade restrictions and distortions in world agricultural markets and food commodity markets and their derivatives.

Goal 3: Good health and well-being

SDG 3 is to: "Ensure healthy lives and promote well-being for all at all ages". Significant strides have been made in increasing life expectancy and reducing some of the common causes of child and maternal mortality. Between 2000 and 2016, the worldwide under-five mortality rate decreased by 47 percent (from 78 deaths per 1,000 live births to 41 deaths per 1,000 live births). Still, the number of children dying under age five is very high: 5.6 million in 2016.

A 2018 study in the journal Nature found that while "nearly all African countries demonstrated improvements for children under 5 years old for stunting, wasting, and underweight... much, if not all of the continent will fail to meet the Sustainable Development Goal target—to end malnutrition by 2030".

SDG 3 has 13 targets and 28 indicators to measure progress toward targets. The first nine targets are "outcome targets". Those are: reduction of maternal mortality; ending all preventable deaths under five years of age; fight communicable diseases; ensure reduction of mortality from non-communicable diseases and promote mental health; prevent and treat substance abuse; reduce road injuries and deaths; grant universal access to sexual and reproductive care, family planning and education; achieve universal health coverage; and reduce illnesses and deaths from hazardous chemicals and pollution. The four "means to achieving" SDG 3 targets are: implement the WHO Framework Convention on Tobacco Control; support research, development and universal access to affordable vaccines and medicines; increase health financing and support health workforce in developing countries; and improve early warning systems for global health risks.

Goal 4: Quality education

SDG 4 is to: "Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all". Major progress has been made in access to education, specifically at the primary school level, for both boys and girls. The number of out-of-school children has almost halved from 112 million in 1997 to 60 million in 2014. In terms of the progress made, global participation in tertiary education reached 224 million in 2018, equivalent to a gross enrollment ratio of 38%.

SDG 4 has ten targets which are measured by 11 indicators. The seven "outcome-oriented targets" are: free primary and secondary education; equal access to quality pre-primary education; affordable technical, vocational and higher education; increased number of people with relevant skills for financial success; elimination of all discrimination in education; universal literacy and numeracy; and education for sustainable development and global citizenship. The three "means of achieving targets" are: build and upgrade inclusive and safe schools; expand higher education scholarships for developing countries; and increase the supply of qualified teachers in developing countries.

Goal 5: Gender equality

SDG 5 is to: "Achieve gender equality and empower all women and girls". In 2020, representation by women in single or lower houses of national parliament reached 25 per cent, up slightly from 22 per cent in 2015. Women now have better access to decision-making positions at the local level, holding 36 per cent of elected seats in local deliberative bodies, based on data from 133 countries and areas. Whilst female genital mutilation/cutting (FGM/C) is becoming less common, at least 200 million girls and women have been subjected to this harmful practice.

Through the pledge to "Leave No One Behind", countries have committed to fast-track progress for those furthest behind, first. SDG 5 aims to grant women and girls equal rights, opportunities to live free without discrimination including workplace discrimination or any violence. This is to achieve gender equality and empower all women and girls.

Goal 6: Clean water and sanitation

Example of sanitation for all: School toilet (IPH school and college, Mohakhali, Dhaka, Bangladesh)

SDG 6 is to: "Ensure availability and sustainable management of water and sanitation for all". The eight targets are measured by 11 indicators. The Joint Monitoring Programme (JMP) of World Health Organisation WHO And United Nations International Children's Emergency fund UNICEF reported in 2017 that 4.5 billion people currently do not have safely managed sanitation. Also in 2017, only 71 per cent of the global population used safely managed drinking water, and 2.2 billion persons were still without safely managed drinking water. With regards to water stress: "In 2017, Central and Southern Asia and Northern Africa registered very high water stress – defined as the ratio of fresh water withdrawn to total renewable freshwater resources – of more than 70 per cent". Official development assistance (ODA) disbursements to the water sector increased to $9 billion in 2018. Evidence shows that both supply- and demand-side interventions financed by aid can contribute to promoting access to water, but consistent long-term investments are needed.

The six "outcome-oriented targets" include: Safe and affordable drinking water; end open defecation and provide access to sanitation, and hygiene, improve water quality, wastewater treatment and safe reuse, increase water-use efficiency and ensure freshwater supplies, implement IWRM, protect and restore water-related ecosystems. The two "means of achieving" targets are to expand water and sanitation support to developing countries, and to support local engagement in water and sanitation management.

Goal 7: Affordable and clean energy

SDG 7 is to: "Ensure access to affordable, reliable, sustainable and modern energy for all". Progress in expanding access to electricity has been made in several countries, notably India, Bangladesh, and Kenya. The global population without access to electricity decreased to about 840 million in 2017 from 1.2 billion in 2010 (sub-Saharan Africa remains the region with the largest access deficit). Renewable energy accounted for 17.5% of global total energy consumption in 2016. Of the three end uses of renewables [electricity, heat, and transport) the use of renewables grew fastest with respect to electricity. Between 2018 and 2030, the annual average investment will need to reach approximately $55 billion to expand energy access, about $700 billion to increase renewable energy and $600 billion to improve energy efficiency.

The goal has five targets to be achieved by 2030. Progress towards the targets is measured by six indicators. Three out of the five targets are "outcome targets": Universal access to modern energy; increase global percentage of renewable energy; double the improvement in energy efficiency. The remaining two targets are "means of achieving targets": to promote access to research, technology and investments in clean energy; and expand and upgrade energy services for developing countries. In other words, these targets include access to affordable and reliable energy while increasing the share of renewable energy in the global energy mix. This would involve improving energy efficiency and enhancing international cooperation to facilitate more open access to clean energy technology and more investment in clean energy infrastructure. Plans call for particular attention to infrastructure support for the least developed countries, small islands and land-locked developing countries.

Goal 8: Decent work and economic growth

SDG 8 is to: "Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all". Over the past five years, economic growth in least developed countries has been increasing at an average rate of 4.3 per cent. In 2018, the global growth rate of real GDP per capita was 2 per cent. In addition, the rate for least developed countries was 4.5 per cent in 2018 and 4.8 per cent in 2019, less than the 7 per cent growth rate targeted in SDG 8. In 2019, 22 per cent of the world's young people were not in employment, education or training, a figure that has hardly changed since 2005. Addressing youth employment means finding solutions with and for young people who are seeking a decent and productive job. Such solutions should address both supply, i.e. education, skills development and training, and demand. In 2018, the number of women engaged in the labor force was put at 48 per cent while that of men was 75 per cent.

SDG 8 has twelve targets in total to be achieved by 2030. Some targets are for 2030; others are for 2020. The first ten are "outcome targets". These are; "sustainable economic growth; diversify, innovate and upgrade for economic productivity", "promote policies to support job creation and growing enterprises", "improve resource efficiency in consumption and production", 'full employment and decent work with equal pay', 'promote youth employment, education and training', 'end modern slavery, trafficking, and child labour', 'protect labour rights and promote safe working environments', 'promote beneficial and sustainable tourism', universal access to banking, insurance and financial services. In addition, there are also two targets for "means of achieving", which are: Increase aid for trade support; develop a global youth employment strategy.

Goal 9: Industry, Innovation and Infrastructure

SDG 9 is to: "Build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation". In 2019, 14% of the world's workers were employed in manufacturing activities. This percentage has not changed much since 2000. The share of manufacturing employment was the largest in Eastern and South-Eastern Asia (18 percent) and the smallest in sub-Saharan Africa (6 percent). The intensity of global carbon dioxide emissions has declined by nearly one quarter since 2000, showing a general decoupling of carbon dioxide emissions from GDP growth. As at 2020, nearly the entire world population lives in an area covered by a mobile network. Millions of people are still unable to access the internet due to cost, coverage, and other reasons. It is estimated that just 53% of the world's population are currently internet users.

SDG 9 has eight targets, and progress is measured by twelve indicators. The first five targets are "outcome targets": develop sustainable, resilient and inclusive infrastructures; promote inclusive and sustainable industrialization; increase access to financial services and markets; upgrade all industries and infrastructures for sustainability; enhance research and upgrade industrial technologies. The remaining three targets are "means of achieving" targets: Facilitate sustainable infrastructure development for developing countries; support domestic technology development and industrial diversification; universal access to information and communications technology.

Goal 10: Reduced inequality

SDG 10 is to: "Reduce income inequality within and among countries". In 73 countries during the period 2012–2017, the bottom 40 per cent of the population saw its incomes grow. Still, in all countries with data, the bottom 40 per cent of the population received less than 25 per cent of the overall income or consumption. Women are more likely to be victims of discrimination than men. Among those with disabilities, 3 in 10 personally experienced discrimination, with higher levels still among women with disabilities. The main grounds of discrimination mentioned by these women was not the disability itself, but religion, ethnicity and sex, pointing to the urgent need for measures to tackle multiple and intersecting forms of discrimination. In 2019, 54 per cent of countries have a comprehensive set of policy measures to facilitate orderly, safe, regular and responsible migration and mobility of people.

The Goal has ten targets to be achieved by 2030. Progress towards targets will be measured by indicators. The first seven targets are "outcome targets": Reduce income inequalities; promote universal social, economic and political inclusion; ensure equal opportunities and end discrimination; adopt fiscal and social policies that promotes equality; improved regulation of global financial markets and institutions; enhanced representation for developing countries in financial institutions; responsible and well-managed migration policies. The other three targets are "means of achievement" targets: Special and differential treatment for developing countries; encourage development assistance and investment in least developed countries; reduce transaction costs for migrant remittances.

Goal 11: Sustainable cities and communities

SDG 11 is to: "Make cities and human settlements inclusive, safe, resilient, and sustainable". The number of slum dwellers reached more than 1 billion in 2018, or 24 per cent of the urban population. The number of people living in urban slums is highest in Eastern and South-Eastern Asia, sub-Saharan Africa and Central and Southern Asia. In 2019, only half of the world's urban population had convenient access to public transport, defined as living within 500 metres' walking distance from a low-capacity transport system (such as a bus stop) and within 1 km of a high-capacity transport system (such as a railway). In the period 1990–2015, most urban areas recorded a general increase in the extent of built-up area per person.

SDG 11 has 10 targets to be achieved, and this is being measured with 15 indicators. The seven "outcome targets" include safe and affordable housing, affordable and sustainable transport systems, inclusive and sustainable urbanization, protection of the world's cultural and natural heritage, reduction of the adverse effects of natural disasters, reduction of the environmental impacts of cities and to provide access to safe and inclusive green and public spaces. The three "means of achieving" targets include strong national and regional development planning, implementing policies for inclusion, resource efficiency, and disaster risk reduction in supporting the least developed countries in sustainable and resilient building.

3.9 billion people—half of the world’s population—currently live in cities globally. It is projected that 5 billion people will live in cities by 2030. Cities across the world occupy just 3 percent of the Earth's land, yet account for 60–80 percent of energy consumption and 75 percent of carbon emissions. Increased urbanization requires increased and improved access to basic resources such as food, energy and water. In addition, basic services such as sanitation, health, education, mobility and information are needed. However, these requirements are unmet globally, which causes serious challenges for the viability and safety of cities to meet increased future demands.

Goal 12: Responsible consumption and production

SDG 12 is to: "Ensure sustainable consumption and production patterns". By 2019, 79 countries and the European Union have reported on at least one national policy instrument to promote sustainable consumption and production patterns. This was done to work towards the implementation of the "10-Year Framework of Programmes on Sustainable Consumption and Production Patterns". Global fossil fuel subsidies in 2018 were $400 billion. This was double the estimated subsidies for renewables and is detrimental to the task of reducing global carbon dioxide emissions.

To ensure that plastic products are more sustainable, thus reducing plastic waste, changes such as decreasing usage and increasing the circularity of the plastic economy are expected to be required. An increase in domestic recycling and a reduced reliance on the global plastic waste trade are other actions that might help meet the goal.

Sustainable Development Goal 12 has 11 targets. The first 8 are "outcome targets", which are: implement the 10‑Year Framework of Programs on Sustainable Consumption and Production Patterns; achieve the sustainable management and efficient use of natural resources; reducing by half the per capita global food waste at the retail and consumer levels and the reduction of food losses along production and supply chains, including post-harvest losses; achieving the environmentally sound management of chemicals and all wastes throughout their life cycle; reducing waste generation through prevention, reduction, recycling and reuse; encourage companies to adopt sustainable practices; promote public procurement practices that are sustainable; and ensure that people everywhere have the relevant information and awareness for sustainable development. The three "means of achievement" targets are: support developing countries to strengthen their scientific and technological capacity; develop and implement tools to monitor sustainable development impacts; and remove market distortions, like fossil fuel subsidies, that encourage wasteful consumption.

Goal 13: Climate action

SDG 13 is to: "Take urgent action to combat climate change and its impacts by regulating emissions and promoting developments in renewable energy". Accelerating climate actions and progress towards a just transition is essential to reducing climate risks and addressing sustainable development priorities, including water, food and human security (robust evidence, high agreement). Accelerating action in the context of sustainable development involves not only expediting the pace of change (speed) but also addressing the underlying drivers of vulnerability and high emissions (quality and depth of change) and enabling diverse communities, sectors, stakeholders, regions and cultures (scale and breadth of change) to participate in just, equitable and inclusive processes that improve the health and well-being of people and the planet.

The decade between 2010 - 2019 was the warmest decade recorded in history. Currently climate change is affecting the global community in every nation across the world. The impact of climate change not only impacts national economies, but also lives and livelihoods, especially those in vulnerable conditions. By 2018, climate change continued exacerbating the frequency of natural disasters, such as massive wildfires, droughts, hurricanes, and floods. Over the period 2000–2018, the greenhouse emissions of developed countries in transitions have declined by 6.5%. However, the emissions of the developing countries are up by 43% in the period between 2000 and 2013. In 2019, at least 120 of 153 developing countries had undertaken activities to formulate and implement national adaptation plans.

SDG 13 and SDG 7 on clean energy are closely related and complementary. The leading sources of the greenhouse gas savings that countries need to focus on in order to realize their commitments under the Paris Agreement are switching fuels to renewable energy and enhancing end-use energy efficiency.

Goal 14: Life below water

SDG 14 is to: "Conserve and sustainably use the oceans, seas and marine resources for sustainable development". The current efforts to protect oceans, marine environments and small-scale fishers are not meeting the need to protect the resources. One of the key drivers of global overfishing is illegal fishing. It threatens marine ecosystems, puts food security and regional stability at risk, and is linked to major human rights violations and even organized crime. Increased ocean temperatures and oxygen loss act concurrently with ocean acidification and constitute the "deadly trio" of climate change pressures on the marine environment.

One indicator (14.1.1b) under Goal 14 specifically relates to reducing impacts from marine plastic pollution.

The first seven targets are "outcome targets": Reduce marine pollution; protect and restore ecosystems; reduce ocean acidification; sustainable fishing; conserve coastal and marine areas; end subsidies contributing to overfishing; increase the economic benefits from sustainable use of marine resources. The last three targets are "means of achieving" targets: To increase scientific knowledge, research and technology for ocean health; support small scale fishers; implement and enforce international sea law.

Oceans and fisheries support the global population's economic, social and environmental needs. Oceans are the source of life of the planet and the global climate system regulator. They are the world's largest ecosystem, home to nearly a million known species. Oceans cover more than two-thirds of the earth's surface and contain 97% of the planet's water. They are essential for making the planet livable. Rainwater, drinking water and climate are all regulated by ocean heat content and currents. Over 3 billion people depend on marine life for their livelihood. However, there has been a 26 percent increase in acidification since the industrial revolution. Effective strategies to mitigate adverse effects of increased ocean acidification are needed to advance the sustainable use of oceans.

Goal 15: Life on land

SDG 15 is to: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss". The proportion of forest area fell, from 31.9 per cent of total land area in 2000 to 31.2 per cent in 2020, representing a net loss of nearly 100 million ha of the world's forests. This was due to decreasing forest area decreased in Latin America, sub-Saharan Africa and South-Eastern Asia, driven by deforestation for agriculture. Desertification affects as much as one-sixth of the world's population, 70% of all drylands, and one-quarter of the total land area of the world. It also leads to spreading poverty and the degradation of billion hectares of cropland. A report in 2020 stated that globally, the species extinction risk has worsened by about 10 per cent over the past three decades.

The nine "outcome targets" include: Conserve and restore terrestrial and freshwater ecosystems; end deforestation and restore degraded forests; end desertification and restore degraded land; ensure conservation of mountain ecosystems, protect biodiversity and natural habitats; protect access to genetic resources and fair sharing of the benefits; eliminate poaching and trafficking of protected species; prevent invasive alien species on land and in water ecosystems; and integrate ecosystem and biodiversity in governmental planning. The three "means of achieving targets" include: Increase financial resources to conserve and sustainably use ecosystem and biodiversity; finance and incentivize sustainable forest management; combat global poaching and trafficking.

Humans depend on earth and the oceans to live. This goal aims at securing sustainable livelihoods that will be enjoyed for generations to come. The human diet is composed 80% of plant life, which makes agriculture a prime economic resource. Forests cover 30 percent of the Earth's surface, provide vital habitats for millions of species, and important sources for clean air and water, as well as being crucial for combating climate change.

Goal 16: Peace, justice and strong institutions

SDG 16 is to: "Promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels". With more than a quarter of children under 5 unregistered worldwide as of 2015, about 1 in 5 countries will need to accelerate progress to achieve universal birth registration by 2030. Data from 38 countries over the past decade suggest that high-income countries have the lowest prevalence of bribery (an average of 3.7 per cent), while lower-income countries have high levels of bribery when accessing public services (22.3 per cent).

The goal has ten "outcome targets": Reduce violence; protect children from abuse, exploitation, trafficking and violence; promote the rule of law and ensure equal access to justice; combat organized crime and illicit financial and arms flows, substantially reduce corruption and bribery; develop effective, accountable and transparent institutions; ensure responsive, inclusive and representative decision-making; strengthen the participation in global governance; provide universal legal identity; ensure public access to information and protect fundamental freedoms. There are also two "means of achieving targets": Strengthen national institutions to prevent violence and combat crime and terrorism; promote and enforce non-discriminatory laws and policies.

Reducing violent crime, sex trafficking, forced labor, and child abuse are clear global goals. The International Community values peace and justice; they call for stronger judicial systems that will enforce laws and work toward a more peaceful and just society. All women need to be able to turn to fair and effective institution to access Justice and important services. We cannot hope for sustainable development without peace and stability in any country.

Goal 17: Partnership for the goals

SDG 17 is to: "Strengthen the means of implementation and revitalize the global partnership for sustainable development". This goal has 19 outcome targets and 24 indicators. Increasing international cooperation is seen as vital to achieving each of the 16 previous goals. Goal 17 is included to assure that countries and organizations cooperate instead of compete. Developing multi-stakeholder partnerships to share knowledge, expertise, technology, and financial support is seen as critical to overall success of the SDGs. The goal encompasses improving north–south and South-South cooperation, and public-private partnerships which involve civil societies are specifically mentioned.

With US$5 trillion to $7 trillion in annual investment required to achieve the SDGs, total official development assistance reached US$147.2 billion in 2017. This, although steady, is below the set target. In 2016, six countries met the international target to keep official development assistance at or above 0.7 percent of gross national income. Humanitarian crises brought on by conflict or natural disasters have continued to demand more financial resources and aid. Even so, many countries also require official development assistance to encourage growth and trade.

Cross-cutting issues and synergies

To achieve sustainable development, three aspects or dimensions need to come together: The economic, socio-political, and environmental dimensions are all critically important and interdependent. Progress will require multidisciplinary and trans-disciplinary research across all three sectors. This proves difficult when major governments fail to support it. Sustainable development can enhance sectoral integration and social inclusion (robust evidence, high agreement). Inclusion merits attention because equity within and across countries is critical to transitions that are not simply rapid but also sustainable and just. Resource shortages, social divisions, inequitable distributions of wealth, poor infrastructure and limited access to advanced technologies can constrain the options and capacities for developing countries to achieve sustainable and just transitions (medium evidence, high agreement) {17.1.1.2}.

According to the UN, the target is to reach the community farthest behind. Commitments should be transformed into effective actions requiring a correct perception of target populations. Data or information must address all vulnerable groups such as children, elderly folks, persons with disabilities, refugees, indigenous peoples, migrants, and internally-displaced persons.

Cross cutting issues include for example gender equality, education, culture and health. These are just some examples of various interlinkages inherent in the SDGs.

Gender equality

The widespread consensus is that progress on all of the SDGs will be stalled if women's empowerment and gender equality are not prioritized, and treated holistically. The SDGs look to policy makers as well as private sector executives and board members to work toward gender equality. Statements from diverse sources, such as the Organisation for Economic Cooperation and Development (OECD), UN Women and the World Pensions Forum, have noted that investments in women and girls have positive impacts on economies. National and global development investments in women and girls often exceed their initial scope.

Gender equality is mainstreamed throughout the SDG framework by ensuring that as much sex-disaggregated data as possible are collected.

Education

Education for sustainable development (ESD) is explicitly recognized in the SDGs as part of Target 4.7 of the SDG on education. UNESCO promotes the Global Citizenship Education (GCED) as a complementary approach. At the same time, it is important to emphasize ESD's importance for all the other 16 SDGs. With its overall aim to develop cross-cutting sustainability competencies in learners, ESD is an essential contribution to all efforts to achieve the SDGs. This would enable individuals to contribute to sustainable development by promoting societal, economic and political change as well as by transforming their own behavior.

Culture

Culture is explicitly referenced in SDG 11 Target 4 ("Strengthen efforts to protect and safeguard the world's cultural and natural heritage"). However, culture is seen as a cross-cutting theme because it impacts several SDGs. For example, culture plays a role in SDGs related to:

  • environment and resilience (Targets 11.4 Cultural & natural heritage, 11.7 Inclusive public spaces, 12.b Sustainable tourism management, 16.4 Recovery of stolen assets),
  • prosperity and livelihoods (Targets 8.3 Jobs, entrepreneurship & innovation; 8.9 Policies for sustainable tourism),
  • knowledge and skills,
  • inclusion and participation (Targets 11.7 Inclusive public spaces, 16.7 Participatory decision-making).

Health

SDGs 1 to 6 directly address health disparities, primarily in developing countries. These six goals address key issues in Global Public Health, Poverty, Hunger and Food security, Health, Education, Gender equality and women's empowerment, and water and sanitation. Public health officials can use these goals to set their own agenda and plan for smaller scale initiatives for their organizations. These goals are designed to lessen the burden of disease and inequality faced by developing countries and lead to a healthier future.

The links between the various sustainable development goals and public health are numerous and well established:

  • Living below the poverty line is attributed to poorer health outcomes and can be even worse for persons living in developing countries where extreme poverty is more common. A child born into poverty is twice as likely to die before the age of five compared to a child from a wealthier family.
  • The detrimental effects of hunger and malnutrition that can arise from systemic challenges with food security are enormous. The World Health Organization estimates that 12.9 percent of the population in developing countries is undernourished.
  • Health challenges in the developing world are enormous, with "only half of the women in developing nations receiving the recommended amount of healthcare they need.
  • Educational equity has yet to be reached in the world. Public health efforts are impeded by this, as a lack of education can lead to poorer health outcomes. This is shown by children of mothers who have no education having a lower survival rate compared to children born to mothers with primary or greater levels of education. Cultural differences in the role of women vary by country, many gender inequalities are found in developing nations. Combating these inequalities has shown to also lead to a better public health outcome.
  • In studies done by the World Bank on populations in developing countries, it was found that when women had more control over household resources, the children benefit through better access to food, healthcare, and education.
  • Basic sanitation resources and access to clean sources of water are a basic human right. However, 1.8 billion people globally use a source of drinking water that is contaminated by feces, and 2.4 billion people lack access to basic sanitation facilities like toilets or pit latrines. A lack of these resources is what causes approximately 1000 children a day to die from diarrheal diseases that could have been prevented from better water and sanitation infrastructure.

Synergies

Synergies amongst the SDGs are "the good antagonists of trade-offs". With regards to SDG 13 on climate action, the IPCC sees robust synergies particularly for the SDGs 3 (health), 7 (clean energy), 11 (cities and communities), 12 (responsible consumption and production) and 14 (oceans).

To meet SDG 13 and other SDGs, sustained long-term investment in green innovation is required: to decarbonize the physical capital stock – energy, industry, and transportation infrastructure – and ensure its resilience to a changing future climate; to preserve and enhance natural capital – forests, oceans, and wetlands; and to train people to work in a climate-neutral economy.

Conceptual problem areas

Competing and too many goals

A commentary in The Economist in 2015 argued that 169 targets for the SDGs is too many, describing them as "sprawling, misconceived" and "a mess" compared to the eight Millennium Development Goals (MDGs). The goals are said to ignore local context. All other 16 goals might be contingent on achieving SDG 1, ending poverty, which should have been at the top of a very short list of goals.

The trade-offs among the 17 SDGs are a difficult barrier to sustainability and might even prevent their realization. For example these are three difficult trade-offs to consider: "How can ending hunger be reconciled with environmental sustainability? (SDG targets 2.3 and 15.2) How can economic growth be reconciled with environmental sustainability? (SDG targets 9.2 and 9.4) How can income inequality be reconciled with economic growth? (SDG targets 10.1 and 8.1)."

Weak on environmental sustainability

SDG wedding cake model: A way of viewing the economic, social and ecological aspects of the Sustainable Development Goals (SDGs).
 

Scholars have criticized that the Sustainable Development Goals fail to recognize that planetary, people and prosperity concerns are all part of one earth system, and that the protection of planetary integrity should not be a means to an end, but an end in itself. A principal concern is that the SDGs remain fixated on the idea that economic growth is foundational to achieve all pillars of sustainable development. Doubts about the steering qualities of the SDGs towards environmental protection arise not only from their ability to steer, but also from the fact that they do not seem to prioritize environmental protection in the first place.

There is no overarching environmental or "planetary" goal. Instead, environmental protection is left to a cluster of environment-focused SDGs down the list at Goal 13, 14 and 15. While including these explicit environmental goals might advance environmental protection, some also argue that Goals 13, 14 and 15 could compartmentalize environmental issues (climate, land and oceans). The goals do not pursue planetary integrity as such, but do recognize the importance of protecting environmental aspects such as climate, land and the oceans.

The SDGs may simply maintain the status quo and fall short of delivering on the ambitious development agenda. The current status quo has been described as "separating human wellbeing and environmental sustainability, failing to change governance and to pay attention to trade-offs, root causes of poverty and environmental degradation, and social justice issues".

Continued global economic growth of 3 percent (Goal 8) may not be reconcilable with ecological sustainability goals, because the required rate of absolute global eco-economic decoupling is far higher than any country has achieved in the past. Anthropologists have suggested that, instead of targeting aggregate GDP growth, the goals could target resource use per capita, with "substantial reductions in high‐income nations."

Environmental constraints and planetary boundaries are underrepresented within the SDGs. For instance, the way the current SDGs are structured leads to a negative correlation between environmental sustainability and SDGs. This means, as the environmental sustainability side of the SDGs is underrepresented, the resource security for all, particularly for lower-income populations, is put at risk. This is not a criticism of the SDGs per se, but a recognition that their environmental conditions are still weak.

The SDGs have been criticized for their inability to protect biodiversity. They could unintentionally promote environmental destruction in the name of sustainable development.

Scientists have proposed several ways to address the weaknesses regarding environmental sustainability in the SDGs:

  • The monitoring of essential variables to better capture the essence of coupled environmental and social systems that underpin sustainable development, helping to guide coordination and systems transformation.
  • More attention to the context of the biophysical systems in different places (e.g., coastal river deltas, mountain areas)
  • Better understanding of feedbacks across scales in space (e.g., through globalization) and time (e.g., affecting future generations) that could ultimately determine the success or failure of the SDGs.

Ethical orientation

There are concerns about the ethical orientation of the SDGs: their focus seems to remain on "growth and use of resources ... and [it] departs from an individual, not collective, point of view"; and they remain "underpinned by strong (Western) modernist notions of development: sovereignty of humans over their environment (anthropocentricism), individualism, competition, freedom (rights rather than duties), self-interest, belief in the market leading to collective welfare, private property (protected by legal systems), rewards based on merit, materialism, quantification of value, and instrumentalization of labor".

Difficulties with tracking qualitative indicators

Regarding the targets of the SDGs, there is generally weak evidence linking the "means of implementation" to outcomes. The targets about "means of implementation" (those denoted with a letter, for example, Target 6.a) are imperfectly conceptualized and inconsistently formulated, and tracking their largely qualitative indicators will be difficult.

Difficulties in achieving impact

There is a lack of impact of the SDGs so far, especially in the are of protecting planetary integrity. Some design elements might have been flawed from the start, such as the number of goals, the structure of the goal framework (for example, the non-hierarchical structure), the coherence between the goals, the specificity or measurability of the targets, the language used in the text, and their reliance on neoliberal economic development-oriented sustainable development as their core orientation.

Some argue that the SDGs' focus on sustainable economic development is inevitably detrimental to planetary integrity and justice, which require both limits to economic growth and the removal of ‘developmental’ disparities between the rich and the poor.

In 2016, the UN ordered an analysis on the reception of the name "the 17 Sustainable Development Goals" with the communication bureau Trollback. It was found out that the word "sustainable" lead to confusion, it made the whole name confusingly long too, so it was rebranded into the "17 Global Goals".

Monitoring mechanism

UN High-Level Political Forum on Sustainable Development (HLPF)

As part of a larger reform, governments decided to terminate the United Nations Commission on Sustainable Development and to establish in its place a High-level Political Forum on Sustainable Development. This new forum was meant to function as a regular meeting place for governments and non-state representatives to assess global progress towards sustainable development. The creation of this overarching institution for sustainability governance was also expected to enhance system-wide coherence in the follow-up and progress reviews under the 2030 Agenda.

The UN High-Level Political Forum on Sustainable Development (HLPF) is the annual space for global monitoring of the SDGs, under the auspices of the United Nations economic and Social Council. In July 2020 the meeting took place online for the first time due to the COVID-19 pandemic. The theme was "Accelerated action and transformative pathways: realizing the decade of action and delivery for sustainable development" and a ministerial declaration was adopted.

High-level progress reports for all the SDGs are published in the form of reports by the United Nations Secretary General. The most recent one is from April 2020.

The literature indicates that the High-level Political Forum has failed to act as an orchestrator to promote system-wide coherence. The reasons for this include its broad and unclear mandate combined with a lack of resources and a lack of political leadership owing to divergent national interests.[10]: 206  Attempts to strengthen the role of the HLPF and to harmonize the voluntary reporting system have not found consensus among governments. This reporting system remains a soft peer-learning mechanism of governments that might even lead to uncontested endorsements of national performances if civil society organizations are not able to act as watchdogs in policy implementation.

Monitoring tools and websites

The online publication SDG-Tracker was launched in June 2018 and presents data across all available indicators. It relies on the Our World in Data database and is also based at the University of Oxford. The publication has global coverage and tracks whether the world is making progress towards the SDGs. It aims to make the data on the 17 goals available and understandable to a wide audience.

The website "allows people around the world to hold their governments accountable to achieving the agreed goals". The SDG-Tracker highlights that the world is currently (early 2019) very far away from achieving the goals.

The Global "SDG Index and Dashboards Report" is the first publication to track countries' performance on all 17 Sustainable Development Goals. The annual publication, co-produced by Bertelsmann Stiftung and SDSN, includes a ranking and dashboards that show key challenges for each country in terms of implementing the SDGs. The publication features trend analysis to show how countries performing on key SDG metrics have changed over recent years in addition to an analysis of government efforts to implement the SDGs.

Reporting on progress

Overall status

Overall status reports made the following statements regarding achieving the SDGs:

  • A study stated in 2022: "Recent assessments show that, under current trends, the world’s social and natural biophysical systems cannot support the aspirations for universal human well-being embedded in the SDGs."
  • The UN Global Sustainable Development Report in 2019 found that: "The world is not on track for achieving most of the 169 targets that comprise the Goals". Several dimensions with cross-cutting impacts across the SDGs are not even moving in the right direction: rising inequalities, climate change, biodiversity loss and increasing amounts of waste from human activity.

A report in 2020 found that due to many economic and social issues, many countries are seeing a major decline in the progress made. In Asia for example, data shows a loss of progress on goals 2,8,10,11, and 15. Recommended approaches to achieve the SDGs are: "Set priorities, focus on harnessing the environmental dimension of the SDGs, understand how the SDGs work as an indivisible system, and look for synergies".

Assessing the political impact of the SDGs

A scientific assessment released in 2022 reviewed over 3,000 scientific articles, mainly from the social sciences. The review found that the world is not on track to achieve the SDGs by 2030 and concluded that the SDGs have so far had only limited political effects in global, national and local governance since their launch in 2015. The authors also state that the SDGs had some positive effects on actors and institutions. There is some evidence that the Sustainable Development Goals have influenced institutions, policies and debates, from global governance to local politics. While this impact has so far largely been discursive, the goals had some normative and institutional effects as well.

Experiences from the implementation of the SDGs in domestic, regional and international contexts reveal little evidence of steering effects towards advancing planetary integrity. This is because all countries largely prioritize the socio-economic SDGs over environmental ones, following their earlier national development policies. Whatever indirect steering effects the SDGs might have in this respect are merely implied through the environmental goals at the bottom of the list of the SDGs (Goal 14 and 15).

There is even emerging evidence that the SDGs might have even adverse effects, by providing a "smokescreen of hectic political activity" that blurs a reality of stagnation, dead ends and business-as-usual. In this perspective, the goals could be seen as a legitimizing meta-narrative that helps international organizations, governments and corporations to merely pretend to be taking decisive action to address the concerns of citizens while clinging to the status quo.

Impacts of COVID-19 pandemic

The COVID-19 pandemic in 2020 had impacts on all 17 goals. It has become "the worst human and economic crisis in a lifetime". The pandemic threatened progress made in particular for SDG 3 (health), SDG 4 (education), SDG 6 (water and sanitation for all), SDG 10 (reduce inequality) and SDG 17 (partnerships).

Uneven priorities of goals

In 2019 five progress reports on the 17 SDGs were published. Three came from the United Nations Department of Economic and Social Affairs (UNDESA), one from the Bertelsmann Foundation and one from the European Union. A review of the five reports analyzed which of the 17 Goals were addressed in priority and which ones were left behind. In explanation of the findings, the Basel Institute of Commons and Economics said Biodiversity, Peace and Social Inclusion were "left behind" by quoting the official SDGs motto "Leaving no one behind".

It has been argued that governments and businesses actively prioritize the social and economic goals over the environmental goals (such as Goal 14 and 15) in both rhetoric and practice.

Implementation

Cost comparison for UN Goals

Implementation of the SDGs started worldwide in 2016. This process can also be called "Localizing the SDGs". In 2019 António Guterres (secretary-general of the United Nations) issued a global call for a "Decade of Action" to deliver the Sustainable Development Goals by 2030. This decade will last from 2020 to 2030. The secretary general of the UN will convene an annual platform for driving the Decade of Action.

Actors

There are four types of actors for implementation of the SDGs: national governments, sub-national authorities, corporations and civil society. All these types of actors are engaged – to differing extents – in implementing the SDGs. Civil society participation and empowerment is routinely promoted as a silver bullet, while not acknowledging the plurality and diverse interests and agendas that exist in this group.

Many governments seem to be committed to the SDGs, and some adjust administrative units or create formal coordinating arrangements. However, such new institutions often seem to reproduce existing structures and priorities. Especially for governments in the Global South with limited fiscal space it is often difficult to reallocate national budgets.

Discursive effects of implementing the Sustainable Development Goals at multiple levels are more dominant, while resource effects are observed the least. Across all actors, however, relationship building is an important motivation for actors to engage with the Sustainable Development Goals. But even with new partnerships, the voluntary nature of the framework makes it easy for incumbent actors to implement the Sustainable Development Goals only in ways that benefit their interests.

Costs

Cost estimates

The United Nations estimates that for Africa, considering the continent's population growth, yearly funding of $1.3 trillion would be needed to achieve the Sustainable Development Goals in Africa. The International Monetary Fund also estimates that $50 billion may be needed only to cover the expenses of climate adaptation.

Estimates for providing clean water and sanitation for the whole population of all continents have been as high as US$200 billion. The World Bank says that estimates need to be made country by country, and reevaluated frequently over time.

In 2014, UNCTAD estimated the annual costs to achieving the UN Goals at US$2.5 trillion per year. Another estimate from 2018 (by the Basel Institute of Commons and Economics, that conducts the World Social Capital Monitor) found that to reach all of the SDGs this would require between US$2.5 and $5.0 trillion per year.

Allocation of funds

There is hardly any evidence that governments significantly reallocate funding to implement the Sustainable Development Goals, neither for national implementation nor international cooperation. The global goals do not seem to have changed public budgets and financial allocation mechanisms in any significant way. Lack of funding could prevent genuine steering effects of the Sustainable Development Goals and indicate that the discursive changes that stem from the SDG process will not lead to transformative structural change and policy reform.

In 2019 António Guterres called for the following priorities with regards to allocation of funds: "a major surge in financing with Member States meeting their official development assistance commitments; fully replenishing Global Funds on Climate and Health; boosting funding for education and other Sustainable Development Goals; supporting innovative forms of financing like Social Impact Bonds; and increasing access to technologies and concessional and green finance for countries most at risk".

The Rockefeller Foundation asserts that "The key to financing and achieving the SDGs lies in mobilizing a greater share of the $200+ trillion in annual private capital investment flows toward development efforts, and philanthropy has a critical role to play in catalyzing this shift." Large-scale funders participating in a Rockefeller Foundation-hosted design thinking workshop concluded that "while there is a moral imperative to achieve the SDGs, failure is inevitable if there aren't drastic changes to how we go about financing large scale change".

In 2017 the UN launched the Inter-agency Task Force on Financing for Development (UN IATF on FfD) that invited to a public dialogue. The top-5 sources of financing for development were estimated in 2018 to be: Real new sovereign debt OECD countries, military expenditures, official increase sovereign debt OECD countries, remittances from expats to developing countries, official development assistance (ODA).

SDG-driven investment

There is growing evidence that some corporate actors, including banks and investors, engage and invest in sustainability practices, promote green finance, facilitate large-scale sustainable infrastructure projects or expand their loan portfolios to environmental and social loans. Such practices are often discursively linked to the Sustainable Development Goals. Some studies warn here of "SDG washing" by corporate actors, selective implementation of the goals, and the political risks linked to private investments in the context of continued shortage of public funding.

Capital stewardship is expected to play a crucial part in the progressive advancement of the SDG agenda to "shift the economic system towards sustainable investment by using the SDG framework across all asset classes".

In 2017, 2018 and early 2019, the World Pensions Council (WPC) held a series of ESG-focused discussions with pension board members (trustees) and senior investment executives from across G20 nations in Toronto, London (with the UK Association of Member-Nominated Trustees, AMNT), Paris and New York – notably on the sidelines of the 73rd session of the United Nations General Assembly. Many pension investment executives and board members confirmed they were in the process of adopting or developing SDG-informed investment processes, with more ambitious investment governance requirements – notably when it comes to climate action, gender equality and social fairness: “they straddle key Sustainable Development Goals (SDGs), including, of course, Gender Equality (SDG 5) and Reduced Inequality (SDG 10) [...] Many pension trustees are now playing for keeps”.

The notion of "SDG Driven Investment" gained further ground amongst institutional investors in the second semester of 2019, notably at the WPC-led G7 Pensions Roundtable held in Biarritz, 26 August 2019, and the Business Roundtable held in Washington, DC, on 19 August 2019.

Communication and advocacy

A proposal to visualize the 17 SDGs in a thematic pyramid.

UN agencies which are part of the United Nations Development Group decided to support an independent campaign to communicate the new SDGs to a wider audience. This campaign, "Project Everyone," had the support of corporate institutions and other international organizations.

Using the text drafted by diplomats at the UN level, a team of communication specialists developed icons for every goal. They also shortened the title "The 17 Sustainable Development Goals" to "Global Goals/17#GlobalGoals," then ran workshops and conferences to communicate the Global Goals to a global audience.

An early concern was that 17 goals would be too much for people to grasp and that therefore the SDGs would fail to get a wider recognition. Without wider recognition the necessary momentum to achieve them by 2030 would not be achieved. Concerned with this, British film-maker Richard Curtis started the organization in 2015 called Project Everyone with the aim to bring the goals to everyone on the planet. Curtis approached Swedish designer Jakob Trollbäck who rebranded them as The Global Goals and created the 17 iconic visuals with clear short names as well as a logotype for the whole initiative. The communication system is available for free. In 2018, Jakob Trollbäck and his company (The New Division), went on to extend the communication system to also include the 169 targets that describe how the goals can be achieved.

The benefits of engaging the affected public in decision making that affects their livelihoods, communities, and environment have been widely recognized. The Aarhus Convention is a United Nations convention passed in 2001, explicitly to encourage and promote effective public engagement in environmental decision making. Information transparency related to social media and the engagement of youth are two issues related to the Sustainable Development Goals that the convention has addressed.

Advocates

In 2019, United Nations Secretary-General António Guterres appointed SDG advocates. The role of the public figures is to raise awareness, inspire greater ambition, and push for faster action on the SDGs. They are:

Global Goals Week

Global Goals Week logo

Global Goals Week is an annual week-long event in September for action, awareness, and accountability for the Sustainable Development Goals. Its a shared commitment for over 100 partners to ensure quick action on the SDGs by sharing ideas and transformative solutions to global problems. It first took place in 2016. It is often held concurrently with Climate Week NYC.

Film festivals

The annual "Le Temps Presse" festival in Paris utilizes cinema to sensitize the public, especially young people, to the Sustainable Development Goals. The origin of the festival was in 2010 when eight directors produced a film titled "8," which included eight short films, each featuring one of the Millennium Development Goals. After 2.5 million viewers saw "8" on YouTube, the festival was created. It now showcases young directors whose work promotes social, environmental and human commitment. The festival now focuses on the Sustainable Development Goals.

The Arctic Film Festival is an annual film festival organized by HF Productions and supported by the SDGs' Partnership Platform. Held for the first time in 2019, the festival is expected to take place every year in September in Longyearbyen, Svalbard, Norway.

UN SDG consultations in Mariupol, Ukraine

In 1972, governments met in Stockholm, Sweden, for the United Nations Conference on the Human Environment to consider the rights of the family to a healthy and productive environment. In 1983, the United Nations created the World Commission on Environment and Development (later known as the Brundtland Commission), which defined sustainable development as "meeting the needs of the present without compromising the ability of future generations to meet their own needs". In 1992, the first United Nations Conference on Environment and Development (UNCED) or Earth Summit was held in Rio de Janeiro, where the first agenda for Environment and Development, also known as Agenda 21, was developed and adopted.

In 2012, the United Nations Conference on Sustainable Development (UNCSD), also known as Rio+20, was held as a 20-year follow up to UNCED. Colombia proposed the idea of the SDGs at a preparation event for Rio+20 held in Indonesia in July 2011. In September 2011, this idea was picked up by the United Nations Department of Public Information 64th NGO Conference in Bonn, Germany. The outcome document proposed 17 sustainable development goals and associated targets. In the run-up to Rio+20 there was much discussion about the idea of the SDGs. At the Rio+20 Conference, a resolution known as "The Future We Want" was reached by member states. Among the key themes agreed on were poverty eradication, energy, water and sanitation, health, and human settlement.

The Rio+20 outcome document mentioned that "at the outset, the OWG [Open Working Group] will decide on its methods of work, including developing modalities to ensure the full involvement of relevant stakeholders and expertise from civil society, Indigenous Peoples, the scientific community and the United Nations system in its work, in order to provide a diversity of perspectives and experience".

In January 2013, the 30-member UN General Assembly Open Working Group on Sustainable Development Goals was established to identify specific goals for the SDGs. The Open Working Group (OWG) was tasked with preparing a proposal on the SDGs for consideration during the 68th session of the General Assembly, September 2013 – September 2014. On 19 July 2014, the OWG forwarded a proposal for the SDGs to the Assembly. After 13 sessions, the OWG submitted their proposal of 8 SDGs and 169 targets to the 68th session of the General Assembly in September 2014. On 5 December 2014, the UN General Assembly accepted the Secretary General's Synthesis Report, which stated that the agenda for the post-2015 SDG process would be based on the OWG proposals.

Ban Ki-moon, the United Nations Secretary-General from 2007 to 2016, has stated in a November 2016 press conference that: "We don't have plan B because there is no planet B."[185] This thought has guided the development of the Sustainable Development Goals (SDGs).

The Post-2015 Development Agenda was a process from 2012 to 2015 led by the United Nations to define the future global development framework that would succeed the Millennium Development Goals. The SDGs were developed to succeed the Millennium Development Goals (MDGs) which ended in 2015. The gaps and shortcomings of MDG Goal 8 (To develop a global partnership for development) led to identifying a problematic "donor-recipient" relationship. Instead, the new SDGs favor collective action by all countries.

The UN-led process involved its 193 Member States and global civil society. The resolution is a broad intergovernmental agreement that acts as the Post-2015 Development Agenda. The SDGs build on the principles agreed upon in Resolution A/RES/66/288, entitled "The Future We Want". This was a non-binding document released as a result of Rio+20 Conference held in 2012.

Negotiations on the Post-2015 Development Agenda began in January 2015 and ended in August 2015. The negotiations ran in parallel to United Nations negotiations on financing for development, which determined the financial means of implementing the Post-2015 Development Agenda; those negotiations resulted in adoption of the Addis Ababa Action Agenda in July 2015.

Country examples

Asia and Pacific

Australia

The Commonwealth of Australia was one of the 193 countries that adopted the 2030 Agenda in September 2015. Implementation of the agenda is led by the Department of Foreign Affairs and Trade (DFAT) and the Department of the Prime Minister and Cabinet (PM&C) with different federal government agencies responsible for each of the goals. Australia is not on-track to achieve the SDGs by 2030. Four modelled scenarios based on different development approaches found that the 'Sustainability Transition' scenario could deliver "rapid and balanced progress of 70% towards SDG targets by 2020, well ahead of the business-as-usual scenario (40%)". In 2020, Australia's overall performance in the SDG Index is ranked 37th out of 166 countries (down from 18th out of 34 countries in 2015).

Bangladesh

Bangladesh, as an active participant in the global process of preparing the Agenda 2030, started its implementation from the very beginning through the integration of SDGs into the national development agenda. The SDGs were integrated with the country's 7th Five Year Plan (7FYP, 2016- 2020) and these were given emphasis while setting the priority areas of the 7FYP such that the achievement of Plan objectives and targets also can contribute towards the achievement of the SDGs. All the 17 goals were integrated into the 7FYP. A Development Results Framework (DRF)- -a robust and rigorous result based monitoring and evaluation framework—was also embedded in the Plan for monitoring the 7FYP. The outcomes and targets in the DRF were aligned with the SDGs focus on macroeconomic development, poverty reduction, employment, education, health, water and sanitation, transport and communication, power, energy and mineral resources, gender and inequality, environment, climate change and disaster management, ICT, urban development, governance, and international cooperation and partnership.

Bhutan

The Sustainable development process in Bhutan has a more meaningful purpose than economic growth alone. The nation's holistic goal is the pursuit of Gross National Happiness (GNH), a term coined in 1972 by the Fourth King of Bhutan, Jigme Singye Wangchuck, which has the principal guiding philosophy for the long term journey as a nation. Therefore, the SDGs find a natural place within the framework of GNH sharing a common vision of prosperity, peace, and harmony where no one is left behind. Just as GNH is both an ideal to be pursued and a practical tool so too the SDGs inspire and guide sustainable action. Guided by the development paradigm of GNH, Bhutan is committed to achieving the goals of SDGs by 2030 since its implementation in September 2015. In line with Bhutan's commitment to the implementation of the SDGs and sustainable development, Bhutan has participated in the Voluntary National Review in the 2018 High-Level Political Forum. As the country has progressed in its 12th five-year plan (2019–2023), the national goals have been aligned with the SDGs and every agency plays a vital role in its own ways to collectively achieving the committed goals of SDGs.

The Government of India established the NITI Aayog to attain sustainable development goals. In March 2018 Haryana became the first state in India to have its annual budget focused on the attainment of SDG with a 3-year action plan and a 7-year strategy plan to implement sustainable development goals when Captain Abhimanyu, Finance Minister of Government of Haryana, unveiled a 1,151,980 lakh (equivalent to 130 billion, US$1.6 billion or €1.6 billion in 2020) annual 2018-19 budget. Also, NITI Aayog starts the exercise of measuring India and its States’ progress towards the SDGs for 2030, culminating in the development of the first SDG India Index - Baseline Report 2018

Africa

Countries in Africa such as Ethiopia, Angola and South Africa worked with UN Country Teams and the United Nations Development Programme (UNDP) to provide support to create awareness about SDGs among government officers, private sector workers, MPs and the civil society.

In Cape Verde, the government received support from the UNDP to convene an international conference on SDGs in June 2015. This contributed to the worldly discussions on the specific needs of Small Island Developing States in the view of the new global agenda on sustainable development. In the UN country team context, the government received support from UNDP to develop a roadmap (a plan) to place SDGs at the middle of its national development planning processes.

In Liberia, the government received support from UNDP to develop a roadmap to domesticate the AU Agenda 2063 and 2030 Agenda into the country's next national development plan. Outlines from the roadmap are steps to translate the Agenda 2063 and the SDGs into policies, plans and programs whiles considering the country is a Fragile State and applies the New Deal Principles.

Uganda was also claimed to be one of the first countries to develop its 2015/16-2019/20 national development plan in line with SDGs. It was estimated by its government that about 76% of the SDGs targets were reflected in the plan and was adapted to the national context. The UN Country Team was claimed to have supported the government to integrate the SDGs.

In Mauritania, the Ministry for the Economy and Finances received support from the UNDP to convene partners such as NGOs, government agencies, other ministries and the private sector in the discussion for implementing of the SDGs in the country, in the context of the UN Country Team. A national workshop was also supported by the UNDP to provide the methodology and tools for mainstreaming the SDGs into the country's new strategy.

The government of countries such as Togo, Sierra Leone, Madagascar and Uganda were claimed to have volunteered to conduct national reviews of their implementation of the 2030 Agenda. Support from UNDP was received to prepare their respective reports presented at the UN High-Level Political Forum. It was held during 11–20 July 2016 in New York in the United States. This forum was the UN global platform to review and follow up the SDGs and 2030 Agenda. It is said to provide guidance on policy to countries for implementing the goals.

Nigeria

Nigeria is one of the countries that presented its Voluntary National Review (VNR) in 2017 & 2020 on the implementation of the SDGs at the High-Level Political Forum on Sustainable Development (HLPF). In 2020, Nigeria ranked 160 on the 2020 world's SDG Index. The government affirmed that Nigeria's current development priorities and objectives are focused on achieving the SDGs. The Lagos SDGs Youth Alliance is another pivotal SDGs Initiative in Nigeria aimed at promoting the involvement of youth in achieving the 2030 Agenda and supporting long-term sustainable development strategy of Lagos state.

Ghana

Ghana aims to align its development priorities in partnership with CSOs and the private sector to achieve the SDGs in Ghana together.

Europe and Middle East

Baltic nations, via the Council of the Baltic Sea States, have created the Baltic 2030 Action Plan.

The World Pensions Forum has observed that the UK and European Union pension investors have been at the forefront of ESG-driven (Environmental, Social and Governance) asset allocation at home and abroad and early adopters of "SDG-centric" investment practices.

Iran

In December 2016 the Government of the Islamic Republic of Iran held a special ceremony announcing a national education initiative that was arranged by the UNESCO office in Iran to implement the educational objectives of this global program. The announcement created a stir among politicians and Marja' in the country.

Lebanon

Lebanon adopted the Sustainable Development Goals in 2015. It presented its first Voluntary National Review VNR in 2018 at the High Level Political Forum in New York. A national committee chaired by the Lebanese Prime Minister is leading the work on the SDGs in the country. In 2019, Lebanon's overall performance in the SDG Index ranked 6th out of 21 countries in the Arab region.

United Kingdom

The UK's approach to delivering the Global SDGs is outlined in Agenda 2030: Delivering the Global Goals, developed by the Department for International Development. In 2019, the Bond network analyzed the UK's global progress on the Sustainable Development Goals (SDGs). The Bond report highlights crucial gaps where attention and investment are most needed. The report was compiled by 49 organizations and 14 networks and working groups.

Americas

United States

193 governments including the United States ratified the SDGs. However, the UN reported minimal progress after three years within the 15-year timetable of this project. Funding remains trillions of dollars short. The United States stand last among the G20 nations to attain these Sustainable Development Goals and 36th worldwide.

Zero-carbon city

From Wikipedia, the free encyclopedia

A zero-carbon city is a goal of city planners that can be variously defined. In a narrower sense of energy production and use, a zero-carbon city is one that generates as much or more carbon-free sustainable energy as it uses. In a broader sense of managing greenhouse gas emissions, a zero-carbon city is one that reduces its carbon footprint to a minimum (ideally 0 or negative) by using renewable energy sources; reducing all types of carbon emissions through efficient urban design, technology use and lifestyle changes; and balancing any remaining emissions through carbon sequestration. Since the supply chains of a city stretch far beyond its borders, Princeton University's High Meadows Environmental Institute suggests using a transboundary definition of a net-zero carbon city as "one that has net-zero carbon infrastructure and food provisioning systems".

Most cities throughout the world burn coal, oil or gas as a source of energy, resulting in the release of carbon dioxide into the atmosphere, a key greenhouse gas. The development of cities is therefore intimately linked to the causes and impacts of climate change. As of 2019, cities accounted for two thirds of all energy consumption and generated 70% of energy-related greenhouse gas emissions. Over 50% of the people in the world currently live in cities, a proportion that is projected to rise to 70% by 2050, and almost 80% by 2080.

Urban development focused on lowering carbon is seen as an inevitable trend for sustainability in urban spaces. Underlying goals include avoiding harm to the planet and countering the impacts of climate change. As of 2022, over 1000 cities worldwide have undertaken steps to transition in response to climate change as part of the Cities Race to Zero campaign, one part of a larger United Nations Race to Zero campaign. Among them are 25 mega-cities including Rio de Janeiro, New York, Paris, Oslo, Mexico City, Melbourne, London, Milan, Cape Town, Buenos Aires, Caracas, Copenhagen, Vancouver and Hong Kong. In the United States, more than 100 cities have pledged to become carbon neutral.

An established modern city attempting to achieve net-zero status needs to assess seven key provisioning systems, for energy, transportation-communications, food, construction materials, water, green infrastructure, and waste-management. Strategies for reaching net zero include developing renewable energy supplies, reducing energy and resource use through better urban design and lifestyle changes, reducing waste, and creating green spaces and carbon sinks to remove carbon from the atmosphere. Sustainable urban planning approaches to zero carbon cities increasingly emphasize the use of locally sourced food, energy, and renewable resources.

Some city planners have designed zero-carbon cities from scratch, instead of using and adapting established cities. This gives city planners greater control over all aspects of city design and how each city can contribute to being without carbon emissions. Such design enables the city to benefit from economies of scale and from construction options that might not be feasible in a city with existing structures. Such zero-carbon cities maintain optimal living conditions and economic development while eliminating environmental impact.

Guiding principles

Net zero is a scientific concept that can be defined in terms of measurable targets. It can provide a frame of reference for understanding and assessing the impact of actions to address climate change. To be used as a framework for climate action, it must be operationalised and measured as part of the ongoing activities of social, political and economic systems.

Time scale is an essential factor driving the urgency of net zero interventions. The impact of carbon emissions on surface warming of the planet is monotonic, near-linear (as of 2021) and long term. Attempts to achieve net zero must therefore be long term plans, maintained over multiple decades. The goal of net zero is to achieve a state of balance that can be maintained over multiple decades to centuries.

Scientists can measure ongoing changes in the global atmosphere and estimate carbon budgets, but identifying and operationalising interventions occurs at multiple levels worldwide. As a frame of reference for decision-makers, global impact must be translated into definable targets for entities at national, subnational, corporate, organizational and individual levels.

In practice, determination of net-zero targets has been self-regulated and voluntary. Entitles set and achieve goals, some participating in voluntary campaigns and initiatives such as the Paris Agreement, the United Nations Race to Zero campaign, Cities Race to Zero, the Net Zero Asset Owners Alliance, and the Science Based Targets initiative. Regular global progress assessments, including those of independent global initiatives such as CDP and the Transition Pathway Initiative (TPI), provide a form of feedback. As of 2022, over 1000 cities, including 25 megacities worldwide and 100 cities in the United States, are part of Cities Race to Zero.

While the setting of targets is key, it must be followed up through effective mechanisms for governance, monitoring, accountability and reporting. Long-term goals must be translated into practical near-term actions, with detailed plans and methods for establishing baselines, measuring outcomes and assessing impacts. In many ways, cities are in a critical position to address climate issues effectively: they are large enough to benefit from economies of scale, and close enough to actual problems to focus on developing real implementable strategies. As demands on their infrastructures increase, they have a strong incentive to address issues and find and share solutions.

Seven aspects of net zero have been identified as highly important to its successful use as a framework for climate action. These have relevance to the development of net zero cities.

  • Sooner is better. Front-loading climate action, combined with long-term planning over years or decades, is the most cost-effective way to reach temperature targets, as well as the most flexible in the face of new information.
  • Be comprehensive. Plans that tackle comprehensive rather than partial emissions reductions are becoming necessary as carbon levels reach critical tipping points. Harder-to-treat problem areas must be addressed as well as easier ones.
  • Beware of over-reliance on early-stage carbon removal strategies. These are not yet well understood and may enable a "business as usual" attitude to climate change.
  • Reassess and improve systems for carbon offsets. Such systems have been questioned in terms of their scientific and technical capabilities; environmental integrity; monitoring, reporting and verification structures; and social and environmental impact.
  • Apply principles of sustainable development. Achieving net zero globally requires implementation of equitable and just transitions that balance social, economic and environmental objectives in areas with very different conditions.
  • Focus on broad strategies for sustainability. Cities can potentially address multiple problems at once, through solutions that are nature-based, biodiversity-based and people-led. It is important to consider that parents with small children, the poor, the elderly and the disabled may experience a city differently from those who are affluent and more easily mobile.
  • See opportunities. New net-zero solutions and innovation will drive economic shifts which will include opportunities for investment, renewal and growth.

There are strong similarities between zero carbon cities and eco-cities. Discussions of eco-cities tend to focus more broadly on social and environmental issues, with less emphasis on carbon monitoring and the necessity of reaching net zero energy balance. Many of the principles proposed for developing eco-cities are also relevant to net zero cities, including revising land use priorities to create sustainable mixed-use communities; revising transportation priorities to favor foot, bicycle, cart and public transit over automobiles; increasing environmental awareness; supporting local agriculture and community gardens; and promoting recycling and resource conservation.

City infrastructure

Urban areas involve essential infrastructure for energy, transport, water, food, shelter, construction, public spaces, and waste management. Transforming cities to achieve net zero sustainability means rethinking both supply-side issues (power supplies and transportation) and demand-side issues (reducing use through better urban design and policy.) Key factors in city planning include density, land use mix, connectivity, and accessibility.

To achieve net zero, a city must collectively reduce emissions of greenhouse gases to zero and cease all practices that emit greenhouse gases. Achieving net zero sustainability also means considering sources and production of materials, and ensuring that what comes into the city travels via zero-emission transport. Appearing to reduce emissions in one location by shifting emissions-causing activities to a different location will not contribute to the global goal of a sustainable net zero environment.

Energy

To become a zero-carbon city, renewable energy must supersede other non-renewable energy sources and become the sole source of energy, so a zero-carbon city is a renewable-energy-economy city. Transitioning to a zero carbon city means examining the generation of power sources, such as renewable electricity and decarbonising electricity production.

Electricity needs are increasingly being met through the development of solar and wind power as energy sources, which are becoming the cheapest forms of power. The shift to solar power, in particular, means that energy can be produced close to its intended use. This is suited to a distributed energy infrastructure in which local areas are connected into a city-wide or region-wide electrical grid. The ability to provide a steady supply of electricity is also being supported by the development of more efficient and cost-effective battery storage technology.

General layout of electricity networks. Voltages and depictions of electrical lines are typical for Germany and other European systems.

Issues of equity, balance, and efficiency are all relevant to energy distribution and use. A net-zero carbon electricity grid is a necessary foundation for supply side strategies that aim to shift provisioning systems for buildings, energy use, mobility, and light industrial energy use to electric power. The development of a net-zero carbon electric grid can become the basis for transitioning key urban activities such as transportation, heating, and cooking from fossil fuels to zero-carbon electricity.

Transport

Elements of Low-Carbon Urban Development
Elements of Low-Carbon Urban Development: less cars, better public transit, mixed use development

Transportation of people and goods is estimated to contribute 20% of global greenhouse gas emissions. In terms of transport, approaches to low-carbon urban development often focus on reducing fossil-fuel based transportation, improving public transit, and creating areas of mixed use development so that people are more likely to work and shop near their homes, reducing transportation needs. A study of 274 cities worldwide suggests that compact urban development is important in both affluent mature cities and developing-country cities with emerging infrastructures, reducing urban emissions by up to 25%.

The transition from fossil-fuel-based cars and trucks to electric vehicles (EVs) is occurring globally. China has been a major center of technology growth for EVs. Vehicle-fuel technologies that can contribute to reductions in energy use include hybrid electric, plug-in electric, natural gas, and bioethanol-powered vehicles. The last diesel and gasoline cars are expected to be produced in the 2020s, with 25% or more of all vehicles worldwide being electric by 2040 as fossil fuel prices rise.

Possible scenario of smart and sustainable mobility

A narrow focus on electrifying vehicles can lead planners to overlook opportunities for increasing efficiency within existing systems. Good urban planning can develop an infrastructure that combines and supports initiatives in multiple areas. For example, the generation of solar power and the provision of recharge hubs near public transit can support the use of electric vehicles for both private and public transit. Another way to support use of electric vehicles might be to integrate EV charging points into lampposts.

Increasingly, city planners are looking to the use of digital technologies to create smarter and more sustainable cities. By gathering large diverse datasets and modelling the impact of possible interventions, planners hope to identify and target key aspects of energy use, air quality, and traffic for improvement. By incorporating smart measurement technology into buildings, lighting, appliances and transportation, systems can better adapt to changing conditions, reduce energy consumption, and improve city services.

Heating, cooling and cooking

Heating, cooling and cooking are also targets for improved energy efficiency and reduction of carbon emissions. Increasingly following Europe and Asia, North Americans are switching from gas or electrical resistance stoves to induction cooking. Consumers are also switching heating systems from coal, fuel oil, or natural gas to electricity-driven steam or hot water; and to air-source or ground-source heat pumps for both heating and cooling.

Food

Food production tends to be heavily dependent on fossil fuels, in the production of nitrogen fertilizer and to power agricultural equipment used in the planting, tending and harvesting of crops. The movement of food from producers to consumers also tends to involve major fossil-fuel costs, since many crops are grown far from their potential market and have a short shelf life. Many countries depend on international markets to obtain critical food supplies. Food production and supply chains are being increasingly destabilized by the effects of climate change on agriculture, the COVID 19 pandemic, and the war in Ukraine. In the United States, at the same time that millions of Americans experience food insecurity, as much as 40 percent of food is wasted.

At the consumer level, steps towards achieving net zero include eating more local and plant-based foods, minimizing food waste, and composting remaining plant-based wastes. Consumers and investors may also choose to support companies based on their carbon footprint and transparency.

In terms of city infrastructure, initiatives to identify and redirect usable food ("food rescue"), to separate waste streams, and to improve handling of food waste are all important. In low-income countries, small-scale and household-level biogas systems are being used to convert wastes into energy. Composting and anaerobic digestion (AD) are increasingly being used in countries at all income levels.

Farmers and farming communities need scientific, technical, and financial support to move to more climate-friendly farming practices and to support initiatives for climate change adaptation, regenerative agriculture and biosequestration. Collaboration between stakeholders at all levels of the private, public and civil sectors is needed to improve food sector infrastructure.

Construction

Common residential energy efficiency features: tight construction, insulation, energy efficient windows, heating and cooling

The energy efficiency of buildings can be assessed and improved in multiple ways that help to reduce carbon emissions. Insulation and energy-efficient windows are commonly used in colder cities. Incorporation of features such as solar panels, green roofs and walls, and heat pumps into new or existing buildings can significantly reduce energy use. New types of materials such as smart glass are being developed to improve the energy efficiency of buildings.

Energy efficiency is not the only factor to consider. Types of materials used can vary widely in both their up-front and over-time carbon costs. It is important to carefully consider the up-front embodied emissions of existing materials. Researchers are also working to develop construction materials that do not release carbon during manufacturing or that can absorb and store more carbon. Steel and cement are heavily used in construction and are very energy intensive to make. Biomass-based materials such as wood and bamboo have lower energy-formation costs. Practices for recycling and reusing construction waste can also save on the amount of energy that has gone into producing and transporting materials.

The size of buildings has an impact on their energy costs in terms of both construction and use. Some recommend a four-storey multi-family building built of low-carbon higher density materials such as straw and wood as an ideal. Mid-size multi-unit buildings can support economies of scale during building and are likely to more economical in use than single-unit homes. High-rise buildings, particularly in hot climates, are more costly to cool. When planning an area, a mix of mid- and high-rise buildings in a compact urban format is likely to be efficient.

Green infrastructure

Green infrastructure includes private and public garden areas, parks, trees, and urban agriculture. Green infrastructure mitigates the effects of carbon emissions in multiple ways, by naturally removing and storing carbon dioxide, and by shading and cooling surrounding areas which reduces energy needs for cooling. The development of green space in cities, particularly long-lived trees, is a cost-effective method of carbon sequestration. The inclusion of green space in urban areas can also help with wide variety of other issues, from stormwater to mental health.

Waste and energy exchange

Separating materials for different recycling streams

Wastes can be managed through a variety of ways, including reuse, recycling, storage, treatment, energy recovery, and disposal. In some cases, a by-product of one set of processes can be used to advantage by someone else, sometimes referred to as urban industrial symbiosis. For example, waste heat from industries and grocery stores has been used to heat residential and commercial buildings. The city of Charlotte, North Carolina has identified becoming a zero waste city as one of four key areas of performance for the goal of developing a circular economy.

Landfill Gas Collection

"Waste-to-energy" describes processes through which useful by-products such as energy can be recovered from otherwise unusable sources. Technologies for carbon capture and storage are being developed to mitigate emissions from fossil fuel power plants and industrial sources. The collection and disposal of waste can potentially be used for the generation of electricity, steam, or heat, but systems to support this are not yet well developed.

Reviews of attempts to attain zero-waste note that the term is used widely and not consistently. Many countries lack an overall zero waste strategy. In most cases in the United States, waste management is inefficient. Without clear national zero waste strategy and policies that identify key areas, it is difficult to coordinate and promote zero waste initiatives in communities and industry.

Measuring net zero

Assessing the urban carbon footprint of cities is a complex issue. Four major accounting systems for measuring urban greenhouse gases have been developed, each with a slightly different conceptualization of what it means to be a net-zero carbon city: territorial source-based accounting, community-wide infrastructure supply chain greenhouse gas footprinting, consumption-based GHG accounting, and total community-wide greenhouse gas footprinting. The United Kingdom is one example of a country that is measuring greenhouse gas emissions and assessing its progress towards net zero using a variety of different official measures.

Examples

Converting existing cities

Increasingly, existing cities are planning to become low or zero carbon. As of 2022, over 1000 cities worldwide have undertaken steps to transition in response to climate change as part of the Cities Race to Zero campaign, one part of the larger United Nations Race to Zero campaign. In the United States, more than 100 cities have pledged to participate in Cities Race to Zero. The following examples illustrate some of the types of initiatives for net zero cities, the extent to which they received multi-level support, and their impact.

Bulawayo, Zimbabwe

As the second largest city in Zimbabwe, with an urban population between 680,000 and 1.5 million people, Bulawayo has gone through a period of rapid growth in the twentieth century; an economic decline in the first decade of the twenty-first century; and next a return to rapid growth that incorporates the United Nations Sustainable Development Goals into the city's strategic plan. Bulawayo hopes to "leapfrog" over existing technology and recreate its economy by adopting next generation technology.

Initiatives include replacement of the city's power station with renewable solar power, "Trackless Trams" for transit, smart technologies for electrical grid management, and circular economy technologies to manage and reduce waste. Researchers are also examining fuelwood production and the potential for carbon sequestration in Bulawayo's public green spaces.

Canberra, Australia

Belconnen Bikeway passing the University of Canberra

The Australian Capital Territory (ACT) which contains the capital Canberra, Australia was the first area in Australia to adopt a net-zero process for an entire urban region. Canberra is known for its strong urban planning and attention to climate change objectives.

ACT passed a Climate Change and Greenhouse Gas Reduction Act as of 2010. Its Climate Council set 5-year goals with regular progress reports. As reported in Climate Change Strategy 2019–2025 (2019), Canberra committed to reducing emissions by 40% from 1990 to 2020. It has achieved that goal by shifting to the purchase of 100% renewable energy sources through the National Electricity Grid. The city has also improved transportation through the use of zero emissions light rail and buses, and added cycling paths. Through these and other initiatives, Canberra's current goal is to use 100% renewable energy by 2045.

Chongming, China

Dongping Forest Park on Chongming Island provides carbon sequestration

Over the last decade, Shanghai, China has implemented dozens of low carbon policies to reduce energy usage and address the effects of climate change. Chongming Island, once a rural area of Shanghai, is one focus for net zero city development. In 2001, the Shanghai Municipal Government (SMG) proposed the creation of a low-carbon eco-island to explore the potential for the development of low-carbon cities. The American firm Skidmore, Owings & Merrill was competitively chosen as the designer of the Chongming Master Plan in 2004.

In 2010, SMG developed the Chongming Eco-Island Construction Outline as a framework with indicators for redesigning Chongming. These included using energy-saving materials, recycled materials and solar energy to construct new buildings; upgrading existing buildings to save energy; closing the existing coal plant; developing renewable energy sources (wind, solar, and biogas); converting buses to electric vehicles and adding foot and bicycle paths; recycling wastewater with low-carbon techniques; reusing wastes for organic fertilizer and biogas; and the development of forests and wetlands to sequester carbon. Factories were required to meet strict ecological requirements or shut down; economic development has been slow and many residents are unemployed.

Copenhagen, Denmark

Middelgrunden offshore wind farm near Copenhagen, Denmark, 2009

In 2012 Copenhagen, Denmark created the CPH2025 Climate Plan with the target of becoming the first carbon-neutral capital by 2025 and for Denmark to be entirely carbon-neutral by 2050. The city has shifted energy and heating systems to use wind, solar and biomass for heating and sea water for cooling; improved transit by using electric cars and adding bicycle paths, and renovated buildings to be more energy efficient From 2009-2022, Copenhagen reduced CO2 emissions by 80%.

To achieve the remaining 20% reduction, the city hoped to use carbon capture and storage (CCS). In 2022, the state indicated that the proposed Amager Resource Centre (ARC) incinerator would not qualify for state financial aid under equity capital requirements of the state's CCS funding program. Copenhagen has stated that it still hopes to achieve a 100% reduction in carbon emissions, but will not be able to do so by 2025.

Denver, USA

Denver, Colorado is an established city with aging building stock. It signed its first Climate Action Plan in 2007 with the initial low-carbon goal of reducing emissions per capita by 10% by 2012. Denver achieved this goal as a result of the passage of renewable portfolio standards by the State of Colorado and climate actions on the part of the city.

The city carefully tracked the progress of its climate action plans in detail and modelled the effects of its programs. They determined that low-carbon actions focusing on efficiency and conservation would be insufficient to reduce GHG emissions at the levels desired. In 2018, Denver changed its strategy to deep decarbonization. Denver is now proposing to make broad systemic changes with the goal of reducing emissions by 80% by 2050.

Constructing new cities

The following examples were prototyped to be newly built zero-carbon cities: Dongtan, China and Masdar City, United Arab Emirates.

Dongtan, Shanghai

Dongtan, China was a sustainable eco-city project planned in the 2000s that was never built. Dongtan was to be located at the east end of Chongming Island, adjacent to the Chongming Dongtan National Nature Reserve. The developers planned on a fully built city, with 80,000 residents by 2020.

The planned city's urban design addressed issues of sustainable energy management, waste management, renewable energy process implementation, architecture, infrastructure, and even the planning of communities and social structures. It proposed to use renewable energy, electric battery or hydrogen-fuel cell transportation, recycled water, hydroponic farming, organic waste recycling and waste-generation of clean energy.

However, by 2008, support for the project had disappeared. Reasons for the project's closure include its proposed location in a highly-valued wetlands area, tensions between its development partners (Arup, a British engineering company, and Shanghai Industrial Investment, a state-owned developer), and loss of political support (due to the jailing of Dongtan's top political backer, former Shanghai Communist Party chief Chen Liangyu, on corruption charges in 2008).

Although the project was not implemented, as an example of urban design it has inspired and informed other cities in China and worldwide. Ideas from Dongtan were incorporated into the renovation of the Chongming District. Dongtan became a model for a subsequently planned eco-city outside Tianjin.

Masdar City, United Arab Emirates

For the Masdar Initiative, Foster + Partners designed a 2.5-square-mile sustainable carbon and waste-free city combining the principles of an ancient walled city with modern alternative energy technologies. One of the city's goals was to be self-sufficient in energy by using about 80% solar energy, along with wind and biomass sources. Solar energy was to be generated through photovoltaic panels, concentrated solar collectors, and solar thermal tubes. The city was designed with wind cooling towers and narrow streets to maximize shaded areas and keep cooling costs down. Buildings incorporate solar and geo-thermal cooling as well as using high-tech construction materials and siting.

Economically, the city was planned to become a center for alternative energy and technology development as well as an example of their use. The site was located close to Abu Dhabi and an international airport, connecting to surrounding communities through a transportation infrastructure of rail, road and public transit. Transportation within the city was to use battery-powered and auto piloted personal rapid transit systems (PRT) as well as walking and cycling. Visitors to the city must park their cars outside and use public transit.

Zero-emissions vehicle

From Wikipedia, the free encyclopedia
 
Critical Mass cylists, San Francisco, April 29, 2005, and Muni Metro electric tram on J Church line
 
The Nissan Leaf electric car is a zero emission vehicle (ZEV).

A zero-emission vehicle, or ZEV, is a vehicle that does not emit exhaust gas or other pollutants from the onboard source of power. The California definition also adds that this includes under any and all possible operational modes and conditions. This is because under cold-start conditions for example, internal combustion engines tend to produce the maximum amount of pollutants. In a number of countries and states, transport is cited as the main source of greenhouse gases (GHG) and other pollutants. The desire to reduce this is thus politically strong.

Terminology

Harmful pollutants to the health and the environment include particulates (soot), hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen. Although not considered emission pollutants by the original California Air Resources Board (CARB) or U.S. Environmental Protection Agency (EPA) definitions, the most recent common use of the term also includes volatile organic compounds, several air toxics (most notably 1,3-Butadiene), and global pollutants such as carbon dioxide and other greenhouse gases.

Examples of zero-emission vehicle with different power sources can include muscle-powered vehicles such as bicycles, electric bicycles, and gravity racers.

Motor vehicles

Also other battery electric vehicles, which may shift emissions to the location where the electricity is generated (if the electricity comes from coal or natural gas power plants—as opposed to hydro-electric, wind power, solar power or nuclear power plants); and fuel cell vehicles powered by hydrogen, which may shift emissions to the location where the hydrogen is generated. It does not include hydrogen internal combustion engine vehicles because these do generate some emissions (although being near-emissionless). It also does not include vehicles running on 100% biofuel as these also emit exhaust gases, despite being carbon neutral overall.

Emissions from the manufacturing process are thus not included in this definition, and it has been argued that the emissions that are created during manufacture are currently of an order of magnitude that is comparable to the emissions that are created during a vehicle's operating lifetime.

However, these vehicles are in the early stages of their development; the manufacturing emissions may decrease by the development of technology, industry, shifting toward mass production and the ever-increasing use of renewable energy throughout the supply-chains.

History

The Indian REVA electric car is a zero emissions vehicle (ZEV).
 
The Honda FCX Clarity, launched in 2008, is a fuel cell hydrogen vehicle compliant with the ZEV standard and sold in Japan and in the U.S. (only in Los Angeles).

Well-to-wheel emissions

The term zero-emissions or ZEV, as originally coined by the California Air Resources Board (CARB), refers only to motor vehicle emissions from the onboard source of power. Therefore, CARB's definition is accounting only for pollutants emitted at the point of the vehicle operation, and the clean air benefits are usually local because depending on the source of the electricity used to recharge the batteries, air pollutant emissions are shifted to the location of the electricity generation plants. In a broader perspective, the electricity used to recharge the batteries must be generated from renewable or clean sources such as wind, solar, hydroelectric, or nuclear power for ZEVs to have almost none or zero well-to-wheel emissions. In other words, if ZEVs are recharged from electricity generated by fossil fuel plants, they cannot be considered as zero emissions.

However, the spread of electrical-powered vehicles can help the development of systems for charging the EV batteries from excess electricity which cannot be used otherwise. For instance, electricity demand is lowest at night and the excess generated electricity at this time can be used for recharging the EVs' batteries. It's worth mentioning that renewable sources such as wind turbines or solar panels are less controllable in terms of the amount of generated electricity compared to fossil fuel power plants; most renewable energy sources are intermittent energy sources. Therefore, development of these resources will lead to excess energy which can be better used by development of EVs. Moreover, most EVs can benefit from regenerative brakes and other optimization systems which increases the energy efficiency in these vehicles.

Fuel cell vehicles (FCVs) can help even more in terms of the development of sustainable energy sources because these cars use hydrogen as their fuel. Compressed hydrogen can be used as an energy storage element, while electricity must be stored in batteries. The hydrogen can be produced by electricity through electrolysis, and this electricity can come from green sources. Hydrogen can be produced in situ, e.g. excess at wind farm when the generated electricity is not needed, or it can be connected to the grid to use the excess electricity from the grid and produce electricity, e.g. at hydrogen pump stations. As a result, development of FCVs can be a big step toward sustainable development and reducing GHG emission in a long-term perspective.

Other countries have a different definition of ZEV, noteworthy the more recent inclusion of greenhouse gases, as many European rules now regulate CO2 emissions. CARB's role in regulating greenhouse gases began in 2004 based on the 2002 Pavley Act (AB 1493), but was blocked by lawsuits and by the EPA in 2007, by rejecting the required waiver. Additional responsibilities were granted to CARB by California's Global Warming Solutions Act of 2006 (AB 32), which includes the mandate to set low-carbon fuel standards.

As a result of an investigation into false advertising regarding "zero-emissions" claims, the Advertising Standards Authority (ASA) in the UK ruled in March 2010 to ban an advertisement from Renault UK regarding its "zero-emission vehicles" because the ad breached CAP (Broadcast) TV Code rules 5.1.1, 5.1.2 (Misleading advertising) and 5.2.1 (Misleading advertising- Evidence) and 5.2.6 (Misleading advertising-Environmental claims.)

Greenhouse gasses and other pollutant emissions are generated by vehicle manufacturing processes. The emissions from manufacturing are many factors larger than the emissions from tailpipes, even in gasoline engine vehicles. Most reports on ZEVs' impact to the climate do not take into account these manufacturing emissions, though over the lifetime of the car the emissions from manufacturing are relatively small.

Considering the current U.S. energy mix, a ZEV would produce an average 58% reduction in carbon dioxide emissions per mile driven. Given the current energy mixes in other countries, it has been predicted that such emissions would decrease by 40% in the U.K. and 19% in China.

Types of zero-emission vehicles

The Tesla Model S electric car is a zero-emission vehicle (ZEV) declared 2013 World Green Car of the Year.

Apart from animal-powered and human-powered vehicles, battery electric vehicles (which include cars, aircraft and boats) also do not emit any of the above pollutants, nor any CO2 gases during use. This is a particularly important quality in densely populated areas, where the health of residents can be severely affected. However, the production of the fuels that power ZEVs, such as the production of hydrogen from fossil fuels, may produce more emissions per mile than the emissions produced from a conventional fossil fueled vehicle. A well-to-wheel life cycle assessment is necessary to understand the emissions implications associated with operating a ZEV.

Bicycles

In the mid-19th century, bicycle ownership became common (during the bike boom)—predating mass car ownership. In the 1960s, the Flying Pigeon bicycle became the single most popular mechanized vehicle on the planet. Some 210 million electric bikes are on the road in China.

Motor vehicles

Segway Personal Transporters are two-wheeled, self-balancing, battery-powered machines that are eleven times more energy-efficient than the average American car. Operating on two lithium-ion batteries, the Segway PT produces zero emissions during operation, and utilizes a negligible amount of electricity while charging via a standard wall outlet.

Marine

PlanetSolar

Wind-powered land vehicles operating on wind exist (using wind turbines and kites). For boats and other watercraft, regular and special sails (as rotorsails, wing sails, turbo sails, skysails) exist that can propel them without emissions.

Lloyd's Register has partnered with a consortium of companies to develop an ammonia-fuelled ship.

Air

Solar Impulse 2
 

An electric aircraft is an aircraft powered by electric motors. Electricity may be supplied by a variety of methods including batteries, ground power cables, solar cells, ultracapacitors, fuel cells and power beaming. Between 2015 and 2016, Solar Impulse 2 completed a circumnavigation of the Earth using solar power.

Incentives

Subsidies for public transport

Japanese public transport is being driven in the direction of zero emissions due to growing environmental concern. Honda has launched a conceptual bus which features exercise machines to the rear of the vehicle to generate kinetic energy used for propulsion.

Due to the stop-start nature of idling in public transport, regenerative braking may be a possibility for public transport systems of the future.

Subsidies for development of electric cars

In an attempt to curb carbon emissions as well as noise pollution in South African cities, the South African Department of Science & Technology (DST), as well as other private investments, have made US$5 million available through the Innovation Fund for the development of the Joule. The Joule is a five-seater car, planned to be released in 2014. However the company ceased trading in 2012.

Low and zero emission zones

Several cities have implemented low-emission zones.
