History of banking

From Wikipedia, the free encyclopedia

The history of banking began with the first prototype banks, that is, the merchants of the world, who gave grain loans to farmers and traders who carried goods between cities. This was around 2000 BCE in Assyria, India and Sumeria. Later, in ancient Greece and during the Roman Empire, lenders based in temples gave loans, while accepting deposits and performing the change of money. Archaeology from this period in ancient China and India also shows evidence of money lending.

Many scholars trace the historical roots of the modern banking system to medieval and Renaissance Italy, particularly the affluent cities of Florence, Venice and Genoa. The Bardi and Peruzzi Families dominated banking in 14th century Florence, establishing branches in many other parts of Europe. The most famous Italian bank was the Medici Bank, established by Giovanni Medici in 1397. The oldest bank still in existence is Banca Monte dei Paschi di Siena, headquartered in Siena, Italy, which has been operating continuously since 1472. Until the end of 2022, the oldest bank still in operation was the Banco di Napoli headquartered in Naples, Italy, which had been operating since 1463.

Development of banking spread from northern Italy throughout the Holy Roman Empire, and in the 15th and 16th century to northern Europe. This was followed by a number of important innovations that took place in Amsterdam during the Dutch Republic in the 17th century, and in London since the 18th century. During the 20th century, developments in telecommunications and computing caused major changes to banks' operations and let banks dramatically increase in size and geographic spread. The financial crisis of 2007–2008 caused many bank failures, including some of the world's largest banks, and provoked much debate about bank regulation.

Ancient authority

The shift from a reliance on hunting and gathering of foods to agricultural practices, starting sometime after 12,000 BCE, resulted in increased stability of economic relations. Such changes in socio-economic conditions began approximately 10,000 years ago in the Fertile Crescent, about 9,500 years ago in northern China, about 5,500 years ago in Mexico, and approximately 4,500 years ago in the eastern parts of the United States.

Monetary

Ancient types of money known as grain-money and food cattle-money were used from around 9000 BCE as two of the earliest commodities used for purposes of bartering.

Anatolian obsidian as a raw material for Stone Age tools was being distributed from as early as about 12,500 BCE, and organized trading of it was occurring during the 9th millennium BCE (Cauvin; Chataigner 1989). Sardinia was one of the four main sites for sourcing the material deposits of obsidian within the Mediterranean; trade using obsidian was replaced during the 3rd millennium BCE by trade of copper and silver.

Record-keeping

Objects used for record keeping, "bulla" and tokens, have been recovered from within Near East excavations, dated to a period beginning 8000 BCE and ending 1500 BCE, as records of the counting of agricultural produce. Commencing in the late fourth millennia mnemonic symbols were in use by members of temples and palaces to record stocks of produce. Types of records accounting for trade exchanges of payments were first being made about 3200 BCE. The Code of Hammurabi, written on a clay tablet around 1700 BCE, describes the regulation of banking activity within the civilization (Armstrong); although still rudimentary, banking was well enough developed to justify laws governing banking operations. Later during the Achaemenid Empire (after 646 BCE), further evidence is found of banking practices in the Mesopotamia region.

Structural

By the 5th millennium BCE, the settlements of Sumer, such as Eridu, were formed around a central temple. In the fifth millennium, people began to build and live in the civilization of cities, providing a structure for the construction of institutions and establishments. Tell Brak and Uruk were two early urban settlements.

Earliest forms of banking

Asia

Mesopotamia and Persia

Banking as an archaic activity (or quasi-banking) is thought to have begun as early as the latter part of the 4th millennium BCE, to the 3rd millennia BCE.

Among many other things, the Code of Hammurabi recorded interest-bearing loans.

Prior to the reign of Sargon I of Akkad (2335–2280 BCE) the occurrence of trade was limited to the internal boundaries of each city-state of Babylon and the temple located at the centre of economic activity therein; trade at the time for citizens external to the city was forbidden.

In Babylonia of 2000 BCE, people depositing gold were required to pay amounts as much as one sixtieth of the total deposited. Both the palaces and temple are known to have provided lending and issuing from the wealth they held—the palaces to a lesser extent. Such loans typically involved issuing seed-grain, with re-payment from the harvest. These basic social agreements were documented in clay tablets, with an agreement on interest accrual. The habit of depositing and storing of wealth in temples continued at least until 209 BCE, as evidenced by Antioch having ransacked or pillaged the temple of Aine in Ecbatana (Media) of gold and silver.

More information comes from the code commissioned by Hammurabi, king of Babylon c. 1792–1750 BCE. Law 100 stipulated that repayment of a loan by a debtor to a creditor was to be on a schedule with a maturity date specified in written contractual terms. Law 122 stipulated that a depositor of gold, silver, or other property must present all articles and a signed contract of bailment to a notary before depositing the articles with a banker, and Law 123 stipulated that a banker was discharged of any liability from a contract of bailment if the notary denied the existence of the contract. Law 124 stipulated that a depositor with a notarized contract of bailment was entitled to redeem the entirety of their deposit, and Law 125 stipulated that a banker was liable for replacement of deposits stolen while in their possession.

Cuneiform records of the house of Egibi of Babylonia describe the family's financial activities as having occurred sometime after 1000 BCE and ending sometime during the reign of Darius I. These records suggest a "lending house" (Silver 2002), a family engaging in "professional banking..." (Dandamaev et al. 2004), and economic activities similar to modern deposit banking. Another interpretation is that the family's activities are better described as entrepreneurship rather than banking (Wunsch 2007). The Murashu family apparently took part in providing credit(Moshenskyi 2008).

Asia Minor

From the fourth millennia previously agricultural settlements began administrative activities.

The temple of Artemis at Ephesus was the largest depository of Asia. A pot-hoard dated to 600 BCE was found in excavations by The British Museum during 1904. During the time of the cessation of the first Mithridatic war, the entire debt being held at the time was annulled by the council. Mark Anthony is recorded to have stolen from the deposits on occasion. The temple served as a depository for Aristotle, Caesar, Dio Chrysostomus, Plautus, Plutarch, Strabo and Xenophon.

The temple to Apollo in Didyma was constructed sometime in the 6th century. A large sum of gold was deposited within the treasury at the time by king Croesus.

India

In ancient India there are evidences of loans from the Vedic period (beginning 1750 BCE). Later during the Maurya dynasty (321 to 185 BCE), an instrument called adesha was in use, which was an order on a banker desiring him to pay the money of the note to a third person, which corresponds to the definition of a bill of exchange as we understand it today. During the Buddhist period, there was considerable use of these instruments. Merchants in large towns gave letters of credit to one another.

China

Main : History of banking in China

In ancient China, starting in the Qin Dynasty (221 to 206 BCE), Chinese currency developed with the introduction of standardized coins that allowed easier trade across China, and led to development of letters of credit. These letters were issued by merchants who acted in ways that today we would understand as banks.

Ancient Egypt

Some scholars suggest that the Egyptian grain-banking system became so well-developed that it was comparable to major modern banks, both in terms of its number of branches and employees, and in terms of the total volume of transactions. During the rule of the Greek Ptolemies, the granaries were transformed into a network of banks centered in Alexandria, where the main accounts from all of the Egyptian regional grain-banks were recorded. This became the site of one of the earliest known government central banks, and may have reached its peak with the assistance of Greek bankers.

According to Muir (2009) there were two types of banks operating within Egypt: royal and private. Documents made to show the banking of taxes were known as peptoken-records.

Greece

Trapezitica is the first source documenting banking (de Soto – p. 41). The speeches of Demosthenes contain numerous references to the issuing of credit (Millett p. 5). Xenophon is credited to have made the first suggestion of the creation of an organisation known in the modern definition as a joint-stock bank in On Revenues written circa 353 BCE.

The city-states of Greece after the Persian Wars produced a government and culture sufficiently organized for the birth of a private citizenship and therefore an embryonic capitalist society, allowing for the separation of wealth from exclusive state ownership to the possibility of ownership by the individual.

According to one source (Dandamaev et al.), trapezites were the first to trade using money, during the 5th century BCE, as opposed to earlier trade which occurred using forms of pre-money.

Specific focus of funds

The earliest forms of storage utilized were the rudimentary money-boxes (ΘΗΣΑΥΡΌΣ) which were made similar in form to the construction of a bee-hive, and were found for example in the Mycenae tombs of 1550–1500 BCE.

Private and civic entities within ancient Grecian society, especially Greek temples, performed financial transactions. (Gilbart p. 3) The temples were the places where treasure was deposited for safe-keeping. The three temples thought the most important were the temple to Artemis in Ephesus, and temple of Hera within Samos, and within Delphi, the temple to Apollo. These consisted of deposits, currency exchange, validation of coinage, and loans.

The first treasury to the Apollonian temple was built before the end of the 7th century BCE. A treasury of the temple was constructed by the city of Siphnos during the 6th century.

Before the destruction by Persians during the 480 invasion, the Athenian Acropolis temple dedicated to Athena stored money; Pericles rebuilt a depository afterward contained within the Parthenon.

During the reign of the Ptolemies, state depositories replaced temples as the location of security-deposits. Records exist to show this having occurred by the end of the reign of Ptolemy I (305–284).

As the need for new buildings to house operations increased, construction of these places within the cities began around the courtyards of the agora (markets).

Geographical focus of banking activities

Athens received the Delian league's treasury during 454.

During the late 3rd and 2nd century BCE, the Aegean island of Delos became a prominent banking center. During the 2nd century, there were for certain three banks and one temple depository within the city.

Thirty-five Hellenistic cities had private banks during the 2nd century (Roberts – p. 130).

Of the settlements of the Greco-Roman world of the 1st century CE, three were of pronounced wealth and centres of banking: Athens, Corinth and Patras.

Loans

Many loans are recorded in writings from the classical age, although a very small proportion were provided by banks. Provision of these were likely an occurrence of Athens, with loans known to have been provided at some time at an annual interest of 12%. Within the boundaries of Athens, bankers' loans are recorded as having been issued on eleven occasions altogether (Bogaert 1968).

Banks sometimes made loans available confidentially, which is, they provided funds without being publicly and openly known to have done so In addition, they kept depositors' names confidential as well. This intermediation per se was known as dia tes trapazēs.

A loan was made by a Temple of Athens to the state during 433–427 BCE.

Rome

Gold coin produced by the Roman Imperial Mint

Roman banking activities were a crucial presence within temples. For instance the minting of coins occurred within temples, most importantly the Juno Moneta temple, though during the time of the Empire, public deposits gradually ceased to be held in temples, and instead were held in private depositories. Still, the Roman Empire inherited the mercantile practices from Greece (Parker).

During 352 BCE a rudimentary public bank (known as dēmosía trápeza ) was formed, with the passing of a consular directive to form a commission of mensarii to deal with debt in the impoverished lower classes. Another source shows banking practices during 325 BCE when, on account of being in debt, the Plebeians were required to borrow money, so newly appointed quinqueviri mensarii were commissioned to provide services to those who had security to provide, in exchange for money from the public treasury. Another source (J. Andreau) has the shops of banking of Ancient Rome firstly opening in the public forums during the period 318 to 310 BCE.

In early Ancient Rome deposit bankers were known as argentarii and at a later time (from the 2nd century CE onward) as nummularii (Andreau 1999 p. 2) or mensarii. The banking-houses were known as Taberae Argentarioe and Mensoe Numularioe. They would set up their stalls in the middle of enclosed courtyards called macella on a long bench called a bancu, from which the words banco and bank are derived. As a money changer, the merchant at the bancu did not so much invest money as merely convert the foreign currency into the only legal tender in Rome—that of the Imperial Mint.

Operations of banking within Roman society were known as officium argentarii. Statutes (125/126 CE) of the Empire described "letter from Caesar to Quietus" show rental monies to be collected from persons using land belonging to a temple and given to the temple treasurer, as decreed by Mettius Modestus, governor of Lycia and Pamphylia. A law, receptum argentarii, obliged a bank to pay its clients debts under guarantee.

Cassius Dio advocated the establishment of a state bank, funded by the sale of all the properties owned at the time by the state.

In the 4th century monopolies existed in Byzantium and in the city of Olbia in Sardinia.

The Roman empire at some time formalized the administrative aspect of banking and instituted greater regulation of financial institutions and financial practices. Charging interest on loans and paying interest on deposits became more highly developed and competitive. The development of Roman banks was limited, however, by the Roman preference for cash transactions. During the reign of the Roman emperor Gallienus (260–268 CE), there was a temporary breakdown of the Roman banking system after the banks rejected the flakes of copper produced by his mints. With the ascent of Christianity, banking became subject to additional restrictions, as the charging of interest was seen as immoral. After the fall of Rome, banking temporarily ended in Europe and was not revived until the time of the crusades.

Religious restrictions on interest

Most early religious systems in the ancient Near East, and the secular codes arising from them, did not forbid usury. These societies regarded inanimate matter as alive, like plants, animals and people, and capable of reproducing itself. Hence if you lent 'food money', or monetary tokens of any kind, it was legitimate to charge interest. Food money in the shape of olives, dates, seeds or animals was lent out as early as c. 5000 BCE, if not earlier. Among the Mesopotamians, Hittites, Phoenicians and Egyptians, interest was legal and often fixed by the state.

Judaism

The Torah and later sections of the Hebrew Bible criticize interest-taking, but interpretations of the Biblical prohibition vary. One common understanding is that Jews are forbidden to charge interest upon loans made to other Jews, but obliged to charge interest on transactions with non-Jews. However, the Hebrew Bible itself gives numerous examples where this provision was evaded.

Deuteronomy 23:19 Thou shalt not lend upon interest to thy brother: interest of money, interest of victuals, interest of any thing that is lent upon interest. Deuteronomy 23:20 Unto a foreigner thou mayest lend upon interest; but unto thy brother thou shalt not lend upon interest; that the LORD thy God may bless thee in all that thou puttest thy hand unto, in the land whither thou goest in to possess it.

In general, it was seen as advantageous to avoid debt at all, to avoid being bound to someone else. Debt was to be avoided and not used to finance consumption, except when in need. However, laws against usury were among many the prophets condemned the people for breaking.

The interpretation that interest could be charged to non-Israelites would be used in the 14th century for Jews living within Christian societies in Europe to justify lending money for profit. This conveniently side stepped the rules against usury in both Judaism and Christianity, as Christians were not involved in the lending but were still free to take the loans.

Christianity

Originally, the charging of interest, known as usury, was banned by Christian churches. This included charging a fee for the use of money, such as at a bureau de change. However over time the charging of interest became acceptable due to the changing nature of money, and the term 'usury' came to be used for charging interest above the rate allowed by law. The notion of "Christian finance" refers to banking and financial activities that came into existence several centuries ago. Despite the prohibition of usury and the Church distrust against exchange activities (as opposed to production activities), a number of operations of a banking or financial nature are in evidence in the activities of the Knights Templar (12th century), Mounts of Piety (appeared in 1462) and the Apostolic Chamber attached directly to the Vatican (money loans, guarantees, issuance of securities, investments, etc.)

The rise of Protestantism in the 16th century weakened Rome's influence, and its dictates against usury became irrelevant in some areas, freeing up the development of banking in Northern Europe. In the late 18th century, Protestant merchant families began to move into banking to an increasing degree, especially in trading countries such as the United Kingdom (Barings), Germany (Schroders, Berenbergs) and the Netherlands (Hope & Co., Gülcher & Mulder). At the same time, new types of financial activities broadened the scope of banking far beyond its origins. One school of thought attributes to Calvinism the setting of the stage for the later development of capitalism in northern Europe. In this view, elements of Calvinism represented a revolt against the medieval condemnation of usury and, implicitly, of profit in general. Such a connection was advanced in influential works by R. H. Tawney (1880–1962) and by Max Weber (1864–1920). According to Weber, the Protestant work ethic was a force behind an unplanned and uncoordinated mass action that influenced the development of capitalism.

Rodney Stark propounds the theory that Christian rationality is the primary driver behind the success of capitalism and the Rise of the West.

Islam

The Quran strictly prohibits lending money on Interest. "O you who have believed, do not consume usury, doubled and multiplied, but fear Allah that you may be successful" (3:130) "and Allah has permitted trade and has forbidden interest" (2:275).

The Quran states that taking interest and making money through unethical means was prohibited for Muslims and in other communities in earlier times as well: "Because of the wrongdoing of the Jews We forbade them good things which were (before) made lawful unto them, and because of their much hindering from Allah's way, And of their taking usury when they were forbidden it, and of their devouring people's wealth by false pretenses, We have prepared for those of them who disbelieve a painful doom." (Al Quran – 4:160–161)

Riba is forbidden in Islamic economic jurisprudence (fiqh). Islamic jurists discuss two types of riba: an increase in capital with no services provided, which the Qur'an prohibits, and commodity exchanges in unequal quantities, which the Sunnah prohibits. Trade in promissory notes (e.g. fiat money and derivatives) is forbidden.

Despite the prohibition of charging interest, during the 20th century a number of developments took place that would lead to an Islamic banking model where no interest is charged but banks would still operate for profit. This was done through charging for loans in alternative ways such as through fees and using different methods of risk sharing and ownership models such as leasing.

Medieval Europe

The roots of modern banking are traceable to medieval and early Renaissance Italy, to rich northern cities such as Florence, Venice, and Genoa.

Emergence of merchant banks

Map showing silk routes

The original banks were "merchant banks" that Italian grain merchants invented in the Middle Ages. As Lombardy merchants and bankers grew in stature based on the strength of the Lombard plains cereal crops, many displaced Jews fleeing Spanish persecution were attracted to the trade. They brought with them ancient practices from the Middle and Far East silk routes. Originally intended to finance long trading journeys, they applied these methods to finance grain production and trading.

Jews could not hold land in Italy, so they entered the great trading piazzas and halls of Lombardy, alongside local traders, and set up their benches to trade in crops. They had one great advantage over the locals: Christians were strictly forbidden usury, defined as lending at interest, as it was considered to be a sin. (Islam similarly condemns usury). The Jewish newcomers, on the other hand, could make high-risk loans to farmers against crops in the field, as they were not subject to the Church's dictates. In this way, they could secure grain-sale rights against the eventual harvest. They then began to advance payment against the future delivery of grain shipped to distant ports. In both cases they made a profit from the present discount against the future price. This two-handed trade was time-consuming and soon there arose a class of merchants who were trading grain debt instead of grain.

The Jewish trader performed both financing (credit) and underwriting (insurance) functions. Financing took the form of a crop loan at the beginning of the growing season, which allowed a farmer to cultivate his annual crop, with the associated expenses of seeding, growing, weeding, and harvesting. Underwriting in the form of crop, or commodity, insurance guaranteed the delivery of the crop to its buyer, typically a merchant wholesaler. In addition, traders performed the merchant function by making arrangements to supply the buyer with the crop through alternative sources—grain stores or alternate markets, for instance—in the event of crop failure. He could also keep the farmer (or other commodity producer) in business during a drought or other crop failure, through the issuance of crop (or commodity) insurance against the hazard of failure of his crop.

Merchant banking progressed from financing trade on one's own behalf to settling trades for others, and then to holding deposits for settlement of "billette" or notes written by the people who were still brokering the actual grain. And so the merchant's "benches" (bank is derived from the Italian for bench, banca, as in a counter) in the great grain markets became centres for holding money against a bill (billette, a note, a letter of formal exchange, later a bill of exchange and later still a cheque).

These deposited funds were intended to be held for the settlement of grain trades, but often were used for the bench's own trades in the meantime. The term bankrupt is a corruption of the Italian banca rotta, or broken bench, which is what happened when someone lost his traders' deposits. The expression of "being broke" has a similar etymology.

Crusades

In the 12th century, the need to transfer large sums of money to finance the Crusades stimulated the re-emergence of banking in western Europe. In 1162, Henry II of England levied a tax to support the crusades—the first of a series of taxes levied by Henry over the years with the same objective. The Templars and Hospitallers acted as Henry's bankers in the Holy Land. The Templars' far-flung, large land holdings across Europe also emerged in the 1100–1300 time frame as the beginning of Europe-wide banking. Their practice was to take in local currency for which a demand note would be given that would be good at any of their castles across Europe, allowing movement of money without the usual risk of robbery while traveling.

Discounting of interest

A sensible manner of discounting interest to the depositors against what could be earned by employing their money in the trade of the bench soon developed; in short, selling an "interest" to them in a specific trade, thus overcoming the usury objection. Once again this merely developed what was an ancient method of financing long-distance transport of goods.

Medieval trade fairs, such as the one in Hamburg, contributed to the growth of banking in a curious way: moneychangers issued documents redeemable at other fairs, in exchange for hard currency. These documents could be cashed at another fair in a different country or at a future fair in the same location. If redeemable at a future date, they would often be discounted by an amount comparable to a rate of interest. Eventually, these documents evolved into bills of exchange, which could be redeemed at any office of the issuing banker. These bills made it possible to transfer large sums of money without the complications of hauling large chests of gold and hiring armed guards to protect the gold from thieves.

Italian bankers

The Republic of Venice, sometimes mistakenly credited with establishing a Bank of Venice in the 12th century, did not formally create a public bank until 1587. However in the 13th and 14th centuries its Grain Office did a banking business that included both deposits and lending. The Republic's system of transferable public debt has also been identified as an important contribution to the development of banking.

In the middle of the 13th century, groups of Italian Christians, particularly the Cahorsins and Lombards, invented legal loopholes to get around the ban on Christian usury; for example, one method of effecting a loan with interest was to offer money without interest, but also require that the loan be insured against possible loss or injury, and/or delays in repayment (see contractum trinius). The Christians utilizing these legal loopholes became known as the pope's usurers, and reduced the importance of the Jews to European monarchs. Later in the Middle Ages, a distinction evolved between things that were consumable (such as food and fuel) and those that were not, with usury permitted on loans that involved the latter.

Coat of arms for the Medici family

The most powerful banking families came from Florence, including the Acciaiuoli, Mozzi, Bardi and Peruzzi families, which established branches in many other parts of Europe. Probably the most famous Italian bank was the Medici bank, set up by Giovanni di Bicci de' Medici in 1397 and continuing until 1494. (Banca Monte dei Paschi di Siena S.p.A. (BMPS) Italy, is in fact the oldest banking organisation to have surviving banking-operations, or services).

By the later Middle Ages, Christian Merchants who lent money with interest were without opposition, and Jews lost their privileged position as money-lenders. Italian bankers would take their place, and by 1327, Avignon had 43 branches of Italian banking houses. In 1347, Edward III of England defaulted on loans. Later there was the bankruptcy of the Bardi (1343 ) and Peruzzi (1346). The accompanying growth of Italian banking in France was the start of the Lombard moneychangers in Europe, who moved from city to city along the busy pilgrim routes important for trade. Key cities in this period were Cahors, the birthplace of Pope John XXII, and Figeac.

After 1400, political forces did in fact somewhat turn against the methods of the Italian free enterprise bankers. In 1401 King Martin I of Aragon had some of these bankers expelled. In 1403, Henry IV of England prohibited them from taking profits in any way in his kingdom. In 1409, Flanders imprisoned and then expelled Genoese bankers. In 1410, all Italian merchants were expelled from Paris. In 1407, the Bank of Saint George, the first state-bank of deposit, was founded in Genoa and was to dominate business in the Mediterranean.

15th–17th centuries – Expansion

Italy

Between 1527 and 1572 a number of important banking family groups arose, such as the Grimaldi, Spinola and Pallavicino families, who were especially influential and wealthy, the Doria, although perhaps less influential, and the Pinelli and the Lomellini.

Spain and the Ottoman Empire

In 1401 the magistrates of Barcelona, then the capital of the Principality of Catalonia, established in the city the first replication of the Venetian model of exchange and deposit, Taula de canvi—the Table of Exchange, considered to be the first public bank of Europe.

Halil Inalcik suggests that, in the 16th century, Marrano Jews (Doña Gracia from House of Mendes) fleeing from Iberia introduced the techniques of European capitalism, banking and even the mercantilist concept of state economy to the Ottoman Empire. In the 16th century, the leading financiers in Istanbul were Greeks and Jews. Many of the Jewish financiers were Marranos who had fled from Iberia during the period leading up to the expulsion of Jews from Spain. Some of these families brought great fortunes with them. The most notable of the Jewish banking families in the 16th-century Ottoman Empire was the Marrano banking house of Mendes, which moved to Istanbul in 1552, under the protection of Sultan Suleyman the Magnificent. When Alvaro Mendes arrived in Istanbul in 1588, he is reported to have brought with him 85,000 gold ducats. The Mendès family soon acquired a dominating position in the state finances of the Ottoman Empire and in commerce with Europe.

Pompeius Occo (1483–1537) came from a north German family and grew up in Augsburg. In 1511 he settled in Amsterdam as a representative of the Fugger banking house and business firm of Augsburg.

They thrived in Baghdad during the 18th and 19th centuries under Ottoman rule, performing critical commercial functions such as moneylending and banking. Like the Armenians, the Jews could engage in necessary commercial activities, such as moneylending and banking, that were proscribed for Muslims under Islamic law.

Court Jew

Court Jews were Jewish bankers or businessmen who lent money and handled the finances of some of the Christian European noble houses, primarily in the 17th and 18th centuries. Court Jews were precursors to the modern financier or Secretary of the Treasury. Their jobs included raising revenues by tax farming, negotiating loans, master of the mint, creating new sources for revenue, floating debentures, devising new taxes. and supplying the military. In addition, the Court Jew acted as personal bankers for nobility: he raised money to cover the noble's personal diplomacy and his extravagances.

Court Jews were skilled administrators and businessmen who received privileges in return for their services. They were most commonly found in Germany, Holland, and Austria, but also in Denmark, England, Hungary, Italy, Poland, Lithuania, Portugal, and Spain. According to Dimont, virtually every duchy, principality, and palatinate in the Holy Roman Empire had a Court Jew.

Germany

In the southern German realm, two great banking families emerged in the 15th century, the Fuggers and the Welsers. They came to control much of the European economy and to dominate international high finance in the 16th century. The Fuggers built the first German social housing area for the poor in Augsburg, the Fuggerei. It still exists, but not the original Fugger Bank which lasted from 1486 to 1647.

Dutch bankers played a central role in establishing banking in the Northern German city states. Berenberg Bank is the oldest bank in Germany and the world's second oldest, established in 1590 by Dutch brothers Hans and Paul Berenberg in Hamburg. The bank is still owned by the Berenberg dynasty.

Netherlands

In the 16th and 17th century, precious metals from the New World, Gold Coast, Japan and other locales were being imported into Europe, with corresponding price increases. Thanks to the free coinage, the Bank of Amsterdam, and the heightened trade and commerce, the Netherlands attracted even more coin and bullion to be deposited in their banks. The concepts of fractional-reserve banking and payment systems were further developed and spread to England and elsewhere.

England

In the City of London there were no banking houses operating in a manner recognized as so today until the 17th century, although the London Royal Exchange was established in 1565.

17th–19th centuries – The emergence of modern banking

By the end of the 16th century and during the 17th, the traditional banking functions of accepting deposits, moneylending, money changing, and transferring funds were combined with the issuance of bank debt that served as a substitute for gold and silver coins.

New banking practices promoted commercial and industrial growth by providing a safe and convenient means of payment and a money supply more responsive to commercial needs, as well as by "discounting" business debt. By the end of the 17th century, banking was also becoming important for the funding requirements of the combative European states. This would lead on to government regulations and the first central banks. The success of the new banking techniques and practices in Amsterdam and London helped spread the concepts and ideas elsewhere in Europe.

Goldsmiths of London

Modern banking practice, including fractional reserve banking and the issue of banknotes, emerged in the 17th century. At the time, wealthy merchants began to store their gold with the goldsmiths of London, who possessed private vaults and charged a fee for their service. In exchange for each deposit of precious metal, the goldsmiths issued receipts certifying the quantity and purity of the metal they held as a bailee; these receipts could not be assigned, only the original depositor could collect the stored goods.

Gradually the goldsmiths began to lend the money out on behalf of the depositor, which led to the development of modern banking practices; promissory notes (which evolved into banknotes) were issued for money deposited as a loan to the goldsmith.

These practices created a new kind of "money" that was actually debt, that is, goldsmiths' debt rather than silver or gold coin, a commodity that had been regulated and controlled by the monarchy. This development required the acceptance in trade of the goldsmiths' promissory notes, payable on demand. Acceptance in turn required a general belief that coin would be available; and a fractional reserve normally served this purpose. Acceptance also required that the holders of debt be able to legally enforce an unconditional right to payment; it required that the notes (as well as drafts) be negotiable instruments. The concept of negotiability had emerged in fits and starts in European money markets, but it was well developed by the 17th century. Nevertheless, an act of Parliament was required in the early 18th century (1704) to overrule court decisions holding that the goldsmiths' notes, despite the "customs of merchants", were not negotiable.

The modern bank

The Louisiana Purchase of 1803 was handled by Francis Baring and Company of London.

In 1695, the Bank of England became one of the first banks to issue banknotes, the first being the short-lived banknotes issued by Stockholms Banco in 1661. Initially, these were hand-written and issued on deposit or as a loan, and promised to pay the bearer the value of the note on demand in specie. By 1745, standardized printed notes ranging from £20 to £1,000 were being issued. Fully printed notes that didn't require the name of the payee and the cashier's signature first appeared in 1855.

In the 18th century, services offered by banks increased. Clearing facilities, security investments, cheques and overdraft protections were introduced. Cheques had been used since the 1600s in England and banks settled payments by direct courier to the issuing bank. Around 1770, they began meeting in a central location, and by the 1800s a dedicated space was established, known as a bankers' clearing house. The method used by the London clearing house involved each bank paying cash to an inspector and then being paid cash by the inspector at the end of each day. The first overdraft facility was set up in 1728 by the Royal Bank of Scotland.

The number of banks increased during the Industrial Revolution and the growing international trade, especially in London. At the same time, new types of financial activities broadened the scope of banking. The merchant-banking families dealt in everything from underwriting bonds to originating foreign loans. These new "merchant banks" facilitated trade growth, profiting from England's emerging dominance in seaborne shipping. Two immigrant families, Rothschild and Baring, established merchant banking firms in London in the late 18th century and came to dominate world banking in the next century.

A great impetus to country banking came in 1797 when, with England threatened by war, the Bank of England suspended cash payments. A handful of Frenchmen landed in Pembrokeshire, causing a panic. Shortly after this incident, Parliament authorised the Bank of England and country bankers to issue notes of low denomination.

Chinese banking

During the Qing dynasty, the private nationwide financial system in China was first developed by the Shanxi merchants, with the creation of so-called "draft banks". The first draft bank Rishengchang was created around 1823 in Pingyao. Some large draft banks had branches in Russia, Mongolia and Japan to facilitate international trade. Throughout the 19th century, the central Shanxi region became the de facto financial centre of Qing China.

With the fall of the Qing dynasty, the financial centers gradually shifted to Shanghai, with western-style modern banks flourishing. Today, the financial centres in China are Hong Kong, Beijing, Shanghai and Shenzhen.

Japanese banking

In 1868, the Meiji government attempted to formulate a functioning banking system, which continued until some time during 1881. They emulated French models. The Imperial mint began using imported machines from Britain in the early years of the Meiji period.

Masayoshi Matsukata was a formative figure of a later banking initiative.

Development of central banking

The Bank of Amsterdam became a model for the functioning of a bank in the capacity of monetary exchange and started the development of central banks. An early central bank was the Sveriges Riksbank, established in 1668, although this was short-lived.

The sealing of the Bank of England Charter (1694).

In England in the 1690s, public funds were in short supply and were needed to finance the ongoing conflict with France. The credit of William III's government was so low in London that it was impossible for it to borrow the £1,200,000 (at 8 per cent) that the government wanted. In order to induce subscription to the loan, the subscribers were to be incorporated by the name of the Governor and Company of the Bank of England. The bank was given exclusive possession of the government's balances, and was the only limited-liability corporation allowed to issue banknotes. The lenders would give the government cash (bullion) and also issue notes against the government bonds, which can be lent again. The £1.2M was raised in 12 days; half of this was used to rebuild the Navy. The establishment of the Bank of England, the model on which most modern central banks have been based on, was devised by Charles Montagu, 1st Earl of Halifax, in 1694, to the plan which had been proposed by William Paterson three years before, but had not been acted upon. He proposed a loan of £1.2M to the government; in return the subscribers would be incorporated as The Governor and Company of the Bank of England with long-term banking privileges including the issue of notes. The Royal Charter was granted on 27 July through the passage of the Tonnage Act 1694.

The Bank of England, established in 1694.

Although the Bank was originally a private institution, by the end of the 18th century it was increasingly being regarded as a public authority with civic responsibility toward the upkeep of a healthy financial system. The currency crisis of 1797, caused by panicked depositors withdrawing from the Bank led to the government suspending convertibility of notes into specie payment. The bank was soon accused by the bullionists of causing the exchange rate to fall from over issuing banknotes, a charge which the Bank denied. Nevertheless, it was clear that the Bank was being treated as an organ of the state.

Henry Thornton, a merchant banker and monetary theorist has been described as the father of the modern central bank. An opponent of the real bills doctrine, he was a defender of the bullionist position and a significant figure in monetary theory, his process of monetary expansion anticipating the theories of Knut Wicksell regarding the "cumulative process which restates the Quantity Theory in a theoretically coherent form". As a response 1797 currency crisis, Thornton wrote in 1802 An Enquiry into the Nature and Effects of the Paper Credit of Great Britain, in which he argued that the increase in paper credit did not cause the crisis. The book also gives a detailed account of the British monetary system as well as a detailed examination of the ways in which the Bank of England should act to counteract fluctuations in the value of the pound.

Walter Bagehot, an influential theorist on the economic role of the central bank.

Until the mid-nineteenth century, commercial banks were able to issue their own banknotes, and notes issued by provincial banking companies were commonly in circulation. Many consider the origins of the central bank to lie with the passage of the Bank Charter Act of 1844. Under the 1844 Act, bullionism was institutionalized in Britain, creating a ratio between the gold reserves held by the Bank of England and the notes that the Bank could issue. The Act also placed strict curbs on the issuance of notes by the country banks.

The Bank accepted the role of 'lender of last resort' in the 1870s after criticism of its lacklustre response to the Overend-Gurney crisis. The journalist Walter Bagehot wrote an influential work on the subject Lombard Street: A Description of the Money Market, in which he advocated for the Bank to officially become a lender of last resort during a credit crunch (sometimes referred to as "Bagehot's dictum").

Central banks were established in many European countries during the 19th century. The War of the Second Coalition led to the creation of the Banque de France in 1800, in an effort to improve the public financing of the war. The US Federal Reserve was created by the U.S. Congress through the passing of The Federal Reserve Act in 1913. Australia established its first central bank in 1920, Colombia in 1923, Mexico and Chile in 1925 and Canada and New Zealand in the aftermath of the Great Depression in 1934. By 1935, the only significant independent nation that did not possess a central bank was Brazil, which subsequently developed a precursor thereto in 1945 and the present central bank twenty years later. Having gained independence, African and Asian countries also established central banks or monetary union.

Rothschilds

The Frankfurt terminus of the Taunus railroad, financed by the Rothschilds. Opened in 1840, it was one of Germany's first railroads.

The Rothschild family pioneered international finance in the early 19th century. The family provided loans to the Bank of England and purchased government bonds in the stock markets. Their wealth has been estimated to possibly be the most in modern history. In 1804, Nathan Mayer Rothschild began to deal on the London stock exchange in financial instruments such as foreign bills and government securities. From 1809 Rothschild began to deal in gold bullion, and developed this as a cornerstone of his business. From 1811 on, in negotiation with Commissary-General John Charles Herries, he undertook to transfer money to pay Wellington's troops, on campaign in Portugal and Spain against Napoleon, and later to make subsidy payments to British allies when these organized new troops after Napoleon's disastrous Russian campaign. His four brothers helped co-ordinate activities across the continent, and the family developed a network of agents, shippers and couriers to transport gold—and information—across Europe. This private intelligence service enabled Nathan to receive in London the news of Wellington's victory at the Battle of Waterloo a full day ahead of the government's official messengers.

The Rothschild family were instrumental in supporting railway systems across the world and in complex government financing for projects such as the Suez Canal. The family bought up a large proportion of the property in Mayfair, London. Major businesses directly founded by Rothschild family capital include Alliance Assurance (1824) (now Royal & SunAlliance); Chemin de Fer du Nord (1845); Rio Tinto Group (1873); Société Le Nickel (1880) (now Eramet); and Imétal (1962) (now Imerys). The Rothschilds financed the founding of De Beers, as well as Cecil Rhodes on his expeditions in Africa and the creation of the colony of Rhodesia.

The Japanese government approached the London and Paris families for funding during the Russo-Japanese War. The London consortium's issue of Japanese war bonds would total £11.5 million (at 1907 currency rates).

From 1919 to 2004 the Rothschilds' Bank in London played a role as place of the gold fixing.

Napoleonic wars and Paris

Napoleon III had the goal of overtaking London to make Paris the premier financial center of the world, but the war in 1870 reduced the range of Parisian financial influence. Paris had emerged as an international center of finance in the mid-19th century second only to London. It had a strong national bank and numerous aggressive private banks that financed projects all across Europe and the expanding French Empire.

One key development was setting up one of the main branches of the Rothschild family. In 1812, James Mayer Rothschild arrived in Paris from Frankfurt, and set up the bank "De Rothschild Frères". This bank funded Napoleon's return from Elba and became one of the leading banks in European finance. The Rothschild banking family of France funded France's major wars and colonial expansion. The Banque de France, founded in 1796 helped resolve the financial crisis of 1848 and emerged as a powerful central bank. The Comptoir National d'Escompte de Paris (CNEP) was established during the financial crisis and the republican revolution of 1848. Its innovations included both private and public sources in funding large projects, and the creation of a network of local offices to reach a much larger pool of depositors.

Building societies

Building societies were established as financial institutions owned by their members as mutual organizations. The origins of the building society as an institution lie in late-18th century Birmingham—a town which was undergoing rapid economic and physical expansion driven by a multiplicity of small metalworking firms, whose many highly skilled and prosperous owners readily invested in property.

Many of the early building societies were based in taverns or coffeehouses, which had become the focus for a network of clubs and societies for co-operation and the exchange of ideas among Birmingham's highly active citizenry as part of the movement known as the Midlands Enlightenment. The first building society to be established was Ketley's Building Society, founded by Richard Ketley, the landlord of the Golden Cross inn, in 1775.

Members of Ketley's society paid a monthly subscription to a central pool of funds which was used to finance the building of houses for members, which in turn acted as collateral to attract further funding to the society, enabling further construction. The first outside the English Midlands was established in Leeds in 1785.

Mutual savings bank

Mutual savings banks also emerged at that time, as financial institutions chartered by government, without capital stock, and owned by their members who subscribe to common funds. The institution most frequently identified as the first modern savings bank was the "Savings and Friendly Society" organized by the Reverend Henry Duncan in 1810, in Ruthwell, Scotland. Rev. Duncan established the small bank in order to encourage his working class congregation to develop thrift.

Another precursor to the modern savings bank originated in Germany, with Franz Hermann Schulze-Delitzsch and Friedrich Wilhelm Raiffeisen who developed cooperative banking models that led on to the credit union movement. The traditional banks had viewed poor and rural communities as unbankable because of very small, seasonal flows of cash and very limited human resources. In the history of credit unions the concepts of cooperative banking spread through northern Europe and onto the US at the turn of the 20th century under a wide range of different names.

Postal savings system

To provide depositors who did not have access to banks a safe, convenient method to save money and to promote saving among the poor, the postal savings system was introduced in Great Britain in 1861. It was vigorously supported by William Ewart Gladstone, then Chancellor of the Exchequer, who saw it as a cheap way to finance the public debt. At the time, banks were mainly in the cities and largely catered to wealthy customers. Rural citizens and the poor had no choice but to keep their funds at home or on their persons. The original Post Office Savings Bank was limited to deposits of £30 a year with a maximum balance of £150. Interest was paid at the rate of two and one-half percent per year on whole pounds in the account.

Similar institutions were created in a number of different countries in Europe, North America, and Japan. One example was in 1881 the Dutch government created the Rijkspostspaarbank (State post savings bank), a postal savings system to encourage workers to start saving. Four decades later they added the Postcheque and Girodienst services allowing working families to make payments via post offices in the Netherlands.

20th century

The first decade of the 20th century saw the Panic of 1907 in the US, which led to numerous runs on banks and became known as the bankers panic.

Great Depression

Crowd at New York's American Union Bank during a bank run early in the Great Depression.

During the Crash of 1929 preceding the Great Depression, margin requirements were only 10%. Brokerage firms, in other words, would lend $9 for every $1 an investor had deposited. When the market fell, brokers called in these loans, which could not be paid back. Banks began to fail as debtors defaulted on debt and depositors attempted to withdraw their deposits en masse, triggering multiple bank runs. Government guarantees and Federal Reserve banking regulations to prevent such panics were ineffective or not used. Bank failures led to the loss of billions of dollars in assets. Outstanding debts became heavier, because prices and incomes fell by 20–50% but the debts remained at the same dollar amount. After the panic of 1929, and during the first 10 months of 1930, 744 US banks failed. By April 1933, around $7 billion in deposits had been frozen in failed banks or those left unlicensed after the March Bank Holiday.

Senator Carter Glass and Rep. Henry B. Steagall (1933)

Bank failures snowballed as desperate bankers called in loans that borrowers did not have time or money to repay. With future profits looking poor, capital investment and construction slowed or completely ceased. In the face of bad loans and worsening future prospects, the surviving banks became even more conservative in their lending. Banks built up their capital reserves and made fewer loans, which intensified deflationary pressures. A vicious cycle developed and the downward spiral accelerated. In all, over 9,000 banks failed during the 1930s.

In response, many countries significantly increased financial regulation. The U.S. established the Securities and Exchange Commission in 1933, and passed the Glass–Steagall Act, which separated investment banking and commercial banking. This was to avoid more risky investment banking activities from ever again causing commercial bank failures.

World Bank and the development of payment technology

1967 letter by the Midland Bank to a customer, informing on the introduction of electronic data processing
 
During the post second world war period and with the introduction of the Bretton Woods system in 1944, two organizations were created: the International Monetary Fund (IMF) and the World Bank. Encouraged by these institutions, commercial banks started to lend to sovereign states in the third world. This was at the same time as inflation started to rise in the west. The Gold standard was eventually abandoned in 1971 and a number of the banks were caught out and became bankrupt due to third world country debt defaults.

This was also a time of increasing use of technology in retail banking. In 1959, banks agreed on a standard for machine readable characters (MICR) that was patented in the United States for use with cheques, which led to the first automated reader-sorter machines. In the 1960s, the first Automated Teller Machines (ATM) or Cash machines were developed and first machines started to appear by the end of the decade. Banks started to become heavy investors in computer technology to automate much of the manual processing, which began a shift by banks from large clerical staffs to new automated systems. By the 1970s the first payment systems started to develop that would lead to electronic payment systems for both international and domestic payments. The international SWIFT payment network was established in 1973 and domestic payment systems were developed around the world by banks working together with governments.

Deregulation and globalization

Bishopsgate in the City of London

Global banking and capital market services proliferated during the 1980s after deregulation of financial markets in a number of countries. The 1986 'Big Bang' in London allowing banks to access capital markets in new ways, which led to significant changes to the way banks operated and accessed capital. It also started a trend where retail banks started to acquire investment banks and stock brokers creating universal banks that offered a wide range of banking services. The trend also spread to the US after much of the Glass–Steagall Act was repealed in 1999 (during the Clinton Administration), this saw US retail banks embark on big rounds of mergers and acquisitions and also engage in investment banking activities.

Financial services continued to grow through the 1980s and 1990s as a result of a great increase in demand from companies, governments, and financial institutions, but also because financial market conditions were buoyant and, on the whole, bullish. Interest rates in the United States declined from about 15% for two-year U.S. Treasury notes to about 5% during the 20-year period, and financial assets grew then at a rate approximately twice the rate of the world economy.

This period saw a significant internationalization of financial markets. The increase of U.S. Foreign investments from Japan not only provided the funds to corporations in the U.S., but also helped finance the federal government.

The dominance of U.S. financial markets was disappearing and there was an increasing interest in foreign stocks. The extraordinary growth of foreign financial markets results from both large increases in the pool of savings in foreign countries, such as Japan, and, especially, the deregulation of foreign financial markets, which enabled them to expand their activities. Thus, American corporations and banks started seeking investment opportunities abroad, prompting the development in the U.S. of mutual funds specializing in trading in foreign stock markets.

Such growing internationalization and opportunity in financial services changed the competitive landscape, as now many banks would demonstrate a preference for the "universal banking" model prevalent in Europe. Universal banks are free to engage in all forms of financial services, make investments in client companies, and function as much as possible as a "one-stop" supplier of both retail and wholesale financial services.

21st century

The early 2000s were marked by consolidation of existing banks and entrance into the market of other financial intermediaries: non-bank financial institution. Large corporate players were beginning to find their way into the financial service community, offering competition to established banks. The main services offered included insurance, pension, mutual, money market and hedge funds, loans and credits and securities. Indeed, by the end of 2001 the market capitalisation of the world's 15 largest financial services providers included four non-banks.

The first decade of the 21st century saw the culmination of the technical innovation in banking over the previous 30 years and saw a major shift away from traditional banking to internet banking. Starting in 2015 developments such as open banking made it easier for third parties to access bank transaction data and introduced standard API and security models.

The process of financial innovation also advanced enormously in the first few decades of the 21st century, increasing the importance and profitability of nonbank finance. Such profitability priorly restricted to the non-banking industry, has prompted the Office of the Comptroller of the Currency (OCC) to encourage banks to explore other financial instruments, diversifying banks' business as well as improving banking economic health. Hence, as the distinct financial instruments are being explored and adopted by both the banking and non-banking industries, the distinction between different financial institutions is gradually vanishing. For example, in 2020, the OCC muddled the distinction between traditional banking and the cryptocurrency ecosystem when it published a number of interpretive letters clarifying national banks' ability to custody cryptocurrency and provide banking services to cryptocurrency companies, as well as use blockchain innovations like stablecoins as settlement infrastructure. In addition, in 2021, the OCC granted its first federal banking charter to Anchorage Digital, a digital asset platform for institutions.

2007–2008 financial crisis

The financial crisis of 2007–2008 caused significant stress on banks around the world. The failure of a large number of major banks resulted in government bail-outs. The collapse and fire sale of Bear Stearns to JPMorgan Chase in March 2008 and the collapse of Lehman Brothers in September that same year led to a credit crunch and global banking crises. In response governments around the world bailed-out, nationalised or arranged fire sales for a large number of major banks. Starting with the Irish government on 29 September 2008, governments around the world provided wholesale guarantees to underwriting banks to avoid panic of systemic failure to the whole banking system. These events spawned the term 'too big to fail' and resulted in a lot of discussion about the moral hazard of these actions.

Emission intensity

From Wikipedia, the free encyclopedia
 
The carbon intensity of electricity measures the amount of greenhouse gases emitted per unit of electricity produced. The units are in grams of CO₂-equivalents per kilowatt-hour of electricity.
 
Carbon emission intensity of economies (2016)
 

An emission intensity (also carbon intensity, C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP). Emission intensities are used to derive estimates of air pollutant or greenhouse gas emissions based on the amount of fuel combusted, the number of animals in animal husbandry, on industrial production levels, distances traveled or similar activity data. Emission intensities may also be used to compare the environmental impact of different fuels or activities. In some case the related terms emission factor and carbon intensity are used interchangeably. The jargon used can be different, for different fields/industrial sectors; normally the term "carbon" excludes other pollutants, such as particulate emissions. One commonly used figure is carbon intensity per kilowatt-hour (CIPK), which is used to compare emissions from different sources of electrical power.

Methodologies

Different methodologies can be used to assess the carbon intensity of a process. Among the most used methodologies there are:

  • The whole life-cycle assessment (LCA): this includes not only the carbon emissions due to a specific process, but also those due to the production and end-of-life of materials, plants and machineries used for the considered process. This is a quite complex method, requiring a big set of variables.
  • The well-to-wheels (WTW), commonly used in the Energy and Transport sectors: this is a simplified LCA considering the emissions of the process itself, the emissions due to the extraction and refining of the material (or fuel) used in the process (also "Upstream emissions"), but excluding the emissions due to the production and end-of-life of plants and machineries. This methodology is used, in the US, by the GREET model and in Europe in the JEC WTW.
  • WTW-LCA hybrid methods, trying to fill in the gap between the WTW and LCA methods. In example, for an Electric Vehicle, an hybrid method considering also the GHG due to the manufacturing and the end of life of the battery gives GHG emissions 10–13% higher, compared to the WTW 
  • Methods not considering LCA aspects but only the emissions occurring during a specific process; i.e. just the combustion of a fuel in a power plant, without considering the Upstream emissions.

Different calculation methods can lead to different results. The results can largely vary also for different geographic regions and timeframes (see, in example, how C.I. of electricity varies, for different European countries, and how varied in a few years: from 2009 to 2013 the C.I. of electricity in the European Union fell on average by 20%, So while comparing different values of Carbon Intensity it is important to correctly consider all the boundary conditions (or initial hypotheses) considered for the calculations. For example, Chinese oil fields emit between 1.5 and more than 40 g of CO2eq per MJ with about 90% of all fields emitting 1.5–13.5 g CO2eq. Such highly skewed carbon intensity patterns necessitate disaggregation of seemingly homogeneous emission activities and proper consideration of many factors for understanding.

An air pollution emission source

Estimating emissions

Emission factors assume a linear relation between the intensity of the activity and the emission resulting from this activity:

Emissionpollutant = Activity * Emission Factorpollutant

Intensities are also used in projecting possible future scenarios such as those used in the IPCC assessments, along with projected future changes in population, economic activity and energy technologies. The interrelations of these variables is treated under the so-called Kaya identity.

The level of uncertainty of the resulting estimates depends significantly on the source category and the pollutant. Some examples:

  • Carbon dioxide (CO2) emissions from the combustion of fuel can be estimated with a high degree of certainty regardless of how the fuel is used as these emissions depend almost exclusively on the carbon content of the fuel, which is generally known with a high degree of precision. The same is true for sulphur dioxide (SO2), since sulphur contents of fuels are also generally well known. Both carbon and sulphur are almost completely oxidized during combustion and all carbon and sulphur atoms in the fuel will be present in the flue gases as CO2 and SO2 respectively.
  • In contrast, the levels of other air pollutants and non-CO2 greenhouse gas emissions from combustion depend on the precise technology applied when fuel is combusted. These emissions are basically caused by either incomplete combustion of a small fraction of the fuel (carbon monoxide, methane, non-methane volatile organic compounds) or by complicated chemical and physical processes during the combustion and in the smoke stack or tailpipe. Examples of these are particulates, NOx, a mixture of nitric oxide, NO, and nitrogen dioxide, NO2).
  • Nitrous oxide (N2O) emissions from agricultural soils are highly uncertain because they depend very much on both the exact conditions of the soil, the application of fertilizers and meteorological conditions.

Electric generation

A literature review of numerous total life cycle energy sources CO2 emissions per unit of electricity generated, conducted by the Intergovernmental Panel on Climate Change in 2011, found that the CO2 emission value, that fell within the 50th percentile of all total life cycle emissions studies were as follows.

In 2009 CO2 intensity of GDP in the OECD countries reduced by 2.9% and amounted to 0.33 kCO2/$05p in the OECD countries. ("$05p" = 2005 US dollars, using purchasing power parities). The USA posted a higher ratio of 0.41 kCO2/$05p while Europe showed the largest drop in CO2 intensity compared to the previous year (−3.7%). CO2 intensity continued to be roughly higher in non-OECD countries. Despite a slight improvement, China continued to post a high CO2 intensity (0.81 kCO2/$05p). CO2 intensity in Asia rose by 2% during 2009 since energy consumption continued to develop at a strong pace. Important ratios were also observed in countries in CIS and the Middle East.

Carbon intensity in Europe

Total CO2 emissions from energy use were 5% below their 1990 level in 2007. Over the period 1990–2007, CO2 emissions from energy use have decreased on average by 0.3%/year although the economic activity (GDP) increased by 2.3%/year. After dropping until 1994 (−1.6%/year), the CO2 emissions have increased steadily (0.4%/year on average) until 2003 and decreased slowly again since (on average by 0.6%/year). Total CO2 emissions per capita decreased from 8.7 t in 1990 to 7.8 t in 2007, that is to say a decrease by 10%. Almost 40% of the reduction in CO2 intensity is due to increased use of energy carriers with lower emission factors. Total CO2 emissions per unit of GDP, the “CO2 intensity”, decreased more rapidly than energy intensity: by 2.3%/year and 1.4%/year, respectively, on average between 1990 and 2007.

However, while the reports from 2007 suggest that the CO2 emissions are going down recent studies find that the global emissions are rapidly escalating. According to the Climate Change 2022 Mitigation of Climate Change report, conducted by the IPCC, it states that it 2019 the world emissions output was 59 gigatonnes. This shows that global emissions has grown rapidly, increasing by about 2.1% each year compared from the previous decade.

The Commodity Exchange Bratislava (CEB) has calculated carbon intensity for Voluntary Emissions Reduction projects carbon intensity in 2012 to be 0.343 tn/MWh.

Emission factors for greenhouse gas inventory reporting

One of the most important uses of emission factors is for the reporting of national greenhouse gas inventories under the United Nations Framework Convention on Climate Change (UNFCCC). The so-called Annex I Parties to the UNFCCC have to annually report their national total emissions of greenhouse gases in a formalized reporting format, defining the source categories and fuels that must be included.

The UNFCCC has accepted the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories, developed and published by the Intergovernmental Panel on Climate Change (IPCC) as the emission estimation methods that must be used by the parties to the convention to ensure transparency, completeness, consistency, comparability and accuracy of the national greenhouse gas inventories. These IPCC Guidelines are the primary source for default emission factors. Recently IPCC has published the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. These and many more greenhouse gas emission factors can be found on IPCC's Emission Factor Database. Commercially applicable organisational greenhouse gas emission factors can be found on the search engine, EmissionFactors.com.

Particularly for non-CO2 emissions, there is often a high degree of uncertainty associated with these emission factors when applied to individual countries. In general, the use of country-specific emission factors would provide more accurate estimates of emissions than the use of the default emission factors. According to the IPCC, if an activity is a major source of emissions for a country ('key source'), it is 'good practice' to develop a country-specific emission factor for that activity.

Emission factors for air pollutant inventory reporting

The United Nations Economic Commission for Europe and the EU National Emission Ceilings Directive (2016) require countries to produce annual National Air Pollution Emission Inventories under the provisions of the Convention on Long-Range Transboundary Air Pollution (CLRTAP).

The European Monitoring and Evaluation Programme (EMEP) Task Force of the European Environment Agency has developed methods to estimate emissions and the associated emission factors for air pollutants, which have been published in the EMEP/CORINAIR Emission Inventory Guidebook on Emission Inventories and Projections TFEIP.

Intensity targets

Coal, being mostly carbon, emits a lot of CO2 when burnt: it has a high CO2 emission intensity. Natural gas, being methane (CH4), has 4 hydrogen atoms to burn for each one of carbon and thus has medium CO2 emission intensity.

Well-to-refinery carbon intensity (CI) of all major active oil fields globally

In an August 31, 2018 article by Masnadi et al. which was published by Science, the authors used "open-source oil-sector CI modeling tools" to "model well-to-refinery carbon intensity (CI) of all major active oil fields globally—and to identify major drivers of these emissions." They compared 90 countries with the highest crude oil footprint. The Science study, which was conducted by Stanford University found that Canadian crude oil is the "fourth-most greenhouse gas (GHG) intensive in the world" behind Algeria, Venezuela and Cameroon.

Environmental effects of transport

From Wikipedia, the free encyclopedia
 

Global greenhouse gas emissions from transportation:

  Cars (40%)
  Trucks (34%)
  Planes (11%)
  Boats (11%)
  Trains (4%)

The environmental effects of transport are significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide.Within the transport sector, road transport is the largest contributor to global warming.

Environmental regulations in developed countries have reduced the individual vehicle's emission. However, this has been offset by an increase in the number of vehicles, and increased use of each vehicle (an effect known as the Jevons paradox). Some pathways to reduce the carbon emissions of road vehicles have been considerably studied. Energy use and emissions vary largely between modes, causing environmentalists to call for a transition from air and road to rail and human-powered transport, and increase transport electrification and energy efficiency.

Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands. By reducing transport emissions globally, it is predicted that there will be significant positive effects on Earth's air quality, acid rain, smog, and climate change. Health effects of transport include noise pollution and carbon monoxide emissions.

While electric cars are being built to cut down [[CO2 emission]] at the point of use, an approach that is becoming popular among cities worldwide is to prioritize public transport, bicycles, and pedestrian movement. Redirecting vehicle movement to create 20-minute neighbourhoods that promotes exercise while greatly reducing vehicle dependency and pollution. Some policies are levying a congestion charge to cars for travelling within congested areas during peak time.

Types of effects

Emissions

The transportation sector is a major source of greenhouse gas emissions (GHGs) in the United States. An estimated 30 percent of national GHGs are directly attributable to transportation—and in some regions, the proportion is even higher. Transportation methods are the greatest contributing source of GHGs in the U.S., accounting for 47 percent of the net increase in total U.S. emissions since 1990.

Land

Other environmental effects of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands. By reducing transportation emissions globally, it is predicted that there will be significant positive effects on Earth's air quality, acid rain, smog and climate change.

Health

The health effects of transport emissions are also of concern. A recent survey of the studies on the effect of traffic emissions on pregnancy outcomes has linked exposure to emissions to adverse effects on gestational duration and possibly also intrauterine growth.

As listed above direct effects such as noise pollution and carbon monoxide emissions create direct and harmful effects on the environment, along with indirect effects. The indirect effects are often of higher consequence which leads to the misconception that it's the opposite since it is frequently understood that initial effects cause the most damage. For example, particulates which are the outcome of incomplete combustion done by an internal combustion engine, are not linked with respiratory and cardiovascular problems since they contribute to other factors not only to that specific condition. Even though the environmental effects are usually listed individually there are also cumulative effects. The synergetic consequences of transport activities. They take into account the varied direct and indirect effects on an ecosystem. Climate change is the sum total result of several natural and human-made factors. 15% of global CO2 emissions are attributed to the transport sector.[11]

Carbon Emissions Per Passenger

The following table compares the emissions of the different transport means for passenger transport in Europe:

Train 156 14
Small car 4 42
Big car 4 55
Bus 12.7 68
Motorbike 1.2 72
Small car 1.5 104
Big car 1.5 158
Plane 88 285

Aviation

Aviation emissions vary based on length of flight. For covering long distances, longer flights are a better investment of the high energy costs of take-off and landing than very short flights, yet by nature of their length inevitably use much more energy. CO2 emissions from air travel range from 0.24 kg CO2 per passenger mile (0.15 kg/km per passenger) for short flights down to 0.18 kg CO2 per passenger mile (0.11 kg/km per passenger) for long flights. Researchers have been raising concern about the globally increasing hypermobility of society, involving frequent and often long-distance air travel and the resulting environmental and climate effects. This threatens to overcome gains made in the efficiency of aircraft and their operations. Climate scientist Kevin Anderson raised concern about the growing effect of air transport on the climate in a paper[13] and a presentation[14] in 2008. He has pointed out that even at a reduced annual rate of increase in UK passenger air travel and with the government's targeted emissions reductions in other energy use sectors, by 2030 aviation would be causing 70% of the UK's allowable CO2 emissions.

Worse, aircraft emissions at stratospheric altitudes have a greater contribution to radiative forcing than do emissions at sea level, due to the effects of several greenhouses gases in the emissions, apart from CO2. The other GHGs include methane (CH4), NOx which leads to ozone [O3], and water vapor. Overall, in 2005 the radiative forcing caused by aviation amounted to 4.9% of all human-caused radiative forcing on Earth's heat balance.

Cycling

Cycling has a low carbon-emission and low environmental footprint. A European study of thousands of urban dwellers found that daily mobility-related CO2 emissions were 3.2 kg (7.1 lb) of CO2 per person, with car travel contributing 70% and cycling 1% (including the entire lifecycle of vehicles and fuels). 'Cyclists' had 84% lower lifecycle CO2 emissions from all daily travel than 'non-cyclists', and the more people cycled on a daily basis, the lower was their mobility-related carbon footprint. Motorists who shifted travel modes from cars to bikes as their ‘main method of travel’ emitted 7.1 kg (16 lb) less CO2 per day. Regular cycling was most strongly associated with reduced life cycle CO2 emissions for commuting and social trips.

Changing from motorised to non-motorised travel behaviour can also have significant effects. A European study of nearly 2000 participants showed that an average person cycling 1 trip/day more and driving 1 trip/day less for 200 days a year would decrease mobility-related lifecycle CO2 emissions by about 0.5 tonnes over a year, representing a substantial share of average per capita CO2 emissions from transport (which are about 1.5 to 2.5 tonnes per year, depending on where you live).

Cars

Car life cycle

Unleaded gasoline has 8.91 kg (19.6 lb) and diesel has 10.15 kg (22.4 lb) of CO2 per gallon. CO2 emissions originating from ethanol are disregarded by international agreements however so gasoline containing 10% ethanol would only be considered to produce 8.02 kg (17.7 lb) of CO2 per gallon. The average fuel economy for new light-duty vehicles sold in the US of the 2017 model year was about 24.9 MPG giving around 0.36 kg (0.79 lb) of CO2 per mile. The Department of Transportation's MOBILE 6.2 model, used by regional governments to model air quality, uses a fleet average (all cars, old and new) of 20.3 mpg giving around 0.44 kg (0.97 lb) of CO2 per mile.

In Europe, the European Commission enforced that from 2015 all new cars registered shall not emit more than an average of 0.13 kg (0.29 lb) of CO2 per kilometre (kg CO2/km). The target is that by 2021 the average emissions for all new cars is 0.095 kg (0.21 lb) of CO2 per kilometre.

Buses

On average, inner city commuting buses emit 0.3 kg (0.66 lb) of CO2 per passenger mile (0.18 kg/km per passenger), and long distance (>20 mi, >32 km) bus trips emit 0.08 kg of CO2 per passenger mile (0.05 kg/km per passenger). Road and transportation conditions vary, so some carbon calculations add 10% to the total distance of the trip to account for potential traffic jams, detours, and pit-stops that may arise.

Rail

On average, commuter rail and subway trains emit 0.17 kg (0.37 lb) of CO2 per passenger mile (0.11 kg/km per passenger), and long distance (>20 mi, >32 km) trains emit 0.19 kg (0.42 lb) of CO2 per passenger mile (0.12 kg/km per passenger). Some carbon calculations add 10% to the total trip distance to account for detours, stop-overs, and other issues that may arise. Electric trains contributes relatively less to the pollution as pollution happens in the power plants which are lot more efficient than diesel driven engines. Generally electric motors even when accounting for transmission losses are more efficient than internal combustion engines with efficiency further improving through recuperative braking.

Infrastructure

Noise can have a direct effect on the natural environment as a result of railroads. Trains contain many different parts that have the potential to be thundering. Wheels, engines and non-aerodynamic cargo that actually vibrate the tracks can cause resounding sounds. Noise caused from directly neighboring railways has the potential to actually lessen value to property because of the inconveniences that railroads provide because of a close proximity. In order to combat unbearable volumes resulting from railways, US diesel locomotives are required to be quieter than 90 decibels at 25 meters away since 1979. This noise, however, has been shown to be harmless to animals, except for horses who will become skittish, that live near it.

Royal Gorge Bridge, Canon City, Colorado

Pollution is another direct result of railroads on the environment. Railroads can make the environment contaminated because of what trains carry. Railway pollution exists in all three states of matter: gaseous, liquid, and solid. Air pollution can occur from boxcars carrying materials such as iron ore, coal, soil, or aggregates and exposing these materials to the air. This can release nitrogen oxide, carbon monoxide, sulphur dioxide, or hydrocarbons into the air. Liquid pollution can come from railways contributing to a runoff into water supplies, like groundwater or rivers and can result from spillage of fuels like oil into water supplies or onto land or discharge of human waste in an unhealthy manner.

Visual Disruption of railroads is defined as a railway changing the way that a previously undisturbed, pristine sight of nature looks. When railways are built in wilderness areas, the environment is visually altered; a viewer will never be able to see the original scene again, and the builders of the railway often alter the landscape around the railway to allow it to ride. Frequent cuttings, embankments, dikes, and stilts are built which will change the way that landscape will look.

An example is the Royal Gorge Bridge in Cañon City, Colorado. This bridge stands 291 metres (955 ft) above the Arkansas River and stretches 383 metres (1,258 ft) across. This bridge that now uses aerial trams is an unforgettable part of this Colorado landscape

Shipping

The fleet emission average for delivery vans, trucks and big rigs is 10.17 kg (22.4 lb) CO2 per gallon of diesel consumed. Delivery vans and trucks average about 7.8 mpg (or 1.3 kg of CO2 per mile) while big rigs average about 5.3 mpg (or 1.92 kg of CO2 per mile).

Ballast water discharge from other sides of the world cause a certain type of pollution different from an emission type pollution as it introduces invasive species that can cause domestic species to go extinct.

Discharges of sewage into water bodies can come from many sources, including wastewater treatment facilities, runoff from livestock operations, and vessels. These discharges have the potential to impair water quality, adversely affecting aquatic environments and increasing the risks to human health. While sewage discharges have potentially wide-ranging effects on all aquatic environments, the effects may be especially problematic in marinas, slow-moving rivers, lakes and other bodies of water with low flushing rates. Environmentally this creates invasive species that often drive other species to their extinction and cause harm to the environment and local businesses.

Emissions from ships have much more significant environmental effects; many ships go internationally from port to port and are not seen for weeks, contributing to air and water pollution on its voyage. Emission of greenhouse gases displaces the amount of gas that allows for UV-rays through the ozone. Sulfur and nitrogen compounds emitted from ship will oxidize in the atmosphere to form sulfate and nitrate. Emissions of nitrogen oxides, carbon monoxide, and volatile organic compounds (VOC) will lead to enhanced surface ozone formation and methane oxidation, depleting the ozone. The effect of the international ship emission on the distribution of chemical compounds such as NOx, CO, O3, OH, SO2, HNO3, and sulfate is studied using a global chemical transport model (CTM), the Oslo CTM2. In particular, the large-scale distribution and diurnal variation of the oxidants and sulfur compounds are studied interactively. Meteorological data (winds, temperature, precipitation, clouds, etc.) used as input for the CTM calculations are provided by a weather prediction model.

Shipping Emissions Factors:

Mode of Transport kg of CO2 per Ton-Mile
Air cargo 0.8063
Truck 0.1693
Train 0.1048
Sea freight 0.0403

The road haulage industry is contributing around 20% of the UK's total carbon emissions a year, with only the energy industry having a larger contribution, at around 39%. Road haulage is a significant consumer of fossil fuels and associated carbon emissions – HGV vehicles account for almost 20 percent of total emissions.

Mitigation of environmental effects

European Investment Bank Climate survey result on countries that want to make public transport more efficient and ban high-emissions vehicles.

Sustainable transport

Sustainable transport is transport with either lower environmental footprint per passenger, per distance or higher capacity. Typically sustainable transport modes are rail, bicycle and walking.

Road-rail parallel layout

Construction of the route through the Kösching forest, north of Ingolstadt, Germany, had a large environmental footprint but with Road-Rail Parallel Layout this would be less than using multiple routes.

Road-Rail Parallel Layout is a design option to reduce the environmental effects of new transportation routes by locating railway tracks alongside a highway. In 1984 the ParisLyon high-speed rail route in France had about 14% parallel layout with the highway, and in 2002, 70% parallel layout was achieved with the Cologne–Frankfurt high-speed rail line.

Following the COVID-19 pandemic, the European Investment Bank Climate survey found that if travel restrictions were lifted, flying less frequently would become the norm.

Involvement

Mitigation does not entirely involve large-scale changes such as road construction, but everyday people can contribute. Walking, cycling trips, short or non-commute trips, can be an alternate mode of transportation when travelling short or even long distances. A multi-modal trip involving walking, a bus ride, and bicycling may be counted solely as a transit trip. Economic evaluations of transportation investments often ignore the true effects of increased vehicular traffic—incremental parking, traffic accidents, and consumer costs—and the real benefits of alternative modes of transport. Most travel models do not account for the negative effects of additional vehicular traffic that result from roadway capacity expansion and overestimate the economic benefits of urban highway projects. Transportation planning indicators, such as average traffic speeds, congestion delays, and roadway level of service, measure mobility rather than accessibility.

Climate change is a factor that 67% of Europeans consider when choosing where to go on holiday. Specifically, people under the age of 30 are more likely to consider climate implications of travelling to vacation spots. 52% of young Europeans, 37% of people ages 30–64 and 25% of people aged above 65, state that in 2022 they will choose to travel by plane. 27% of young people claim they will travel to a faraway destination.

Europeans expect lifestyle changes to experience great transformation in the next 20 years. 31% of respondents to a climate survey conducted in 2021 believe that most people will no longer own their own vehicle, while 63% believe that teleworking will become the norm to reduce emissions and mitigate the effects of climate change. 48% predict that energy quotas will be individually assigned.

The European Investment Bank's Climate survey found that two-thirds of Europeans plan to sacrifice the trip of their dreams to reduce emissions and combat climate change.

Influence of e-commerce

As large retail corporations in recent years have focused attention on eCommerce, many have begun to offer fast (e.g. 2-day) shipping. These fast shipping options get products and services to the hands of buyers faster than ever before, but have they are negative externalities on public roads and climate change. A survey in 2016 by UPS shows that 46% of online shoppers abandoned an unused shopping cart due to a shipping time that was way too long and that 1 and 3 online shoppers look at the speed of delivery from the marketplaces they buy from. Consumers are demanding the fast delivery of goods and services. AlixPartners LLP found that consumers expect to wait an average of 4.8 days for delivery, down from 5.5 days in 2012. And the share of those who are willing to wait more than five days has declined to 60% from 74% in four years.

E-commerce shopping can be seen as the best way to reduce one's carbon footprint. Yet, this is only true to some extent. Shopping online is less energy intensive than driving to a physical store location and then driving back home. This is because shipping can take advantage of economies of scale. However, these benefits are diminished when e-commerce stores package items separately or when customers buy items separately and do not take the time to one stop shop. For large stores with a large online presence, they can have millions of customers opting for these shipping benefits. As a result, they are unintentionally increasing carbon emissions from not consolidating their purchases. Josué Velázquez-Martínez, a sustainable logistics professor at MIT notes that "if you are willing to wait a week for shipping, you just kill 20 trees instead of 100 trees." The only time shipping works in being less energy intensive is when customer do not choose rush delivery, which includes 2-day shipping. M. Sanjayan, the CEO of Conservation International, explains that getting your online purchase delivered at home in just two days puts more polluting vehicles on the road. In addition to standard shipping, consumers must be satisfied with their purchases so that they do not constantly returns items. By returning shipments on standard shipping, the positive contribution to environment is being taken back. In research done by Vox, they found in 2016 transportation overtook power plants as the top prouder of carbon dioxide emissions in the US for the first time since 1979. These environmental issues came from nearly a quarter of transportation trucks that either carry medium and heavy duty loads of merchandise; these trucks are often the ones doing e-commerce shipping.

This is the market for shipping pollution. The optimal quantity and the optimal tax per unit of pollution can be found at the intersection of MAC and MD. As the quantity of pollution decreases (emissions), the cost to decrease each marginal unit of pollution increases.

Since 2009, UPS deliveries have increased by 65%. With the increase in deliveries, there is a demand for trucks on the road, resulting in more carbon emissions in our atmosphere. More recently, there has been research to help combat greenhouse gas emission to the atmosphere with better traffic signals. These WiFi signals cut down on wait time at stop lights and reduce wasting fuel. These signals help automobiles adjust their velocity so that they can  increase their chances of getting through the light, smoothing travel patterns and obtaining fuel-economy benefits. These small adjustments result in big changes in fuel savings. The cities that have started implementing smart light technology such as San Jose, CA and Las Vegas, NV. Light technology has shown to save 15-20% in fuel savings. According to the United States Environmental Protection Agency, transportation is the second leading source of GHG emission behind electricity and project that by 2050 freight transportation emissions will pass passenger vehicle emissions. Another technological advancements is truck platooning, trucks are able to send signals to neighboring trucks about their speed. This communication between vehicles reduces congestion on the roads and reduce drag, increasing fuel savings by 10 to 20%.

With these tech implementations in major cities and towns, there is the ability to reach an optimal level of pollution given the rise of e-commerce shipments. The figure above illustrates that decreasing emissions would result in the equilibrium for the market of shipping population, which can be done by consolidating packages, light technology, or truck platooning.
