Emissions trading is a market-oriented approach to controlling pollution by providing economic incentives for reducing the emissions of pollutants . The concept is also known as cap and trade (CAT) or emissions trading scheme (ETS). One prominent example is carbon emission trading for CO 2 and other greenhouse gases which is a tool for climate change mitigation . Other schemes include sulfur dioxide and other pollutants.
150-458: Carbon emission trading (also called carbon market , emission trading scheme ( ETS ) or cap and trade ) is a type of emissions trading scheme designed for carbon dioxide (CO 2 ) and other greenhouse gases (GHGs). A form of carbon pricing , its purpose is to limit climate change by creating a market with limited allowances for emissions. Carbon emissions trading is a common method that countries use to attempt to meet their pledges under
300-493: A subsidy for the sector in question. The Garnaut Climate Change Review considered the free allocation of permits unjustified in any circumstances, arguing that governments could deal with market failure or claims for compensation more transparently with the revenue from full auctioning of permits. Another economically efficient solution to carbon leakage is border adjustment, where tariffs are set on imported goods from less regulated countries. A problem with border adjustments
450-830: A "carbon tax", and when the government proposed the Clean Energy Bill in February 2011, the opposition denounced it as a broken election promise. The Lower House passed the bill in October 2011 and the Upper House in November 2011. The Liberal Party vowed to repeal the bill if elected. The bill thus resulted in passage of the Clean Energy Act, which possessed a great deal of flexibility in its design and uncertainty over its future. Emissions trading In an emissions trading scheme,
600-658: A benchmarking approach, if designed properly, would reward more efficient operations". Hepburn et al. state that, empirically, businesses tend to oppose auctioning of emissions permits, while economists almost uniformly recommend auctioning permits. Auctioning permits provides the government with revenues, which can be used to fund low-carbon investment and cuts in distortionary taxes . Auctioning permits can therefore be more efficient and equitable than allocating permits. Garnaut stated that full auctioning will provide greater transparency and accountability and lower implementation and transaction costs as governments retain control over
750-527: A central authority or governmental body allocates or sells a limited number (a "cap") of permits that allow a discharge of a specific quantity of a specific pollutant over a set time period. Polluters are required to hold permits in amount equal to their emissions. Polluters that want to increase their emissions must buy permits from others willing to sell them. Emissions trading is a type of flexible environmental regulation that allows organizations and markets to decide how best to meet policy targets. This
900-466: A chance to finalize a Protocol that could secure ratification. Specifically, COP-6 was intended to complete work on the two-year Buenos Aires Plan of Action (BAPA), agreed upon at COP-4. However, these groups saw the United States as a roadblock to finalize such a Protocol. The discussions evolved rapidly into a high-level negotiation over the major political issues. These included major controversy over
1050-604: A firm being given fewer permits in the future for aiming to cut emissions drastically. Another method of grandfathering is to base allocations on current production of economic goods rather than historical emissions. Under this method of allocation, the government will set a benchmark level of emissions for each good deemed to be sufficiently trade exposed and allocate firms units based on their production of this good. However, allocating permits in proportion to output implicitly subsidises production. The Garnaut Climate Change Review noted that grandfathered permits are not free of cost. As
1200-414: A firm that reduced its emissions would receive fewer permits in the future (IMF, 2008, pp. 25–26). There are costs that emitters do face, e.g., the costs of the fuel being used, but there are other costs that are not necessarily included in the price of a good or service. These other costs are called external costs (Halsnæs et al. , 2007). This problem can also be criticized on ethical grounds, since
1350-403: A government political process, individual companies are free to choose how or whether to reduce their emissions. Failure to report emissions and surrender emission permits is often punishable by a further government regulatory mechanism, such as a fine that increases costs of production. Firms will choose the least-cost way to comply with the pollution regulation, which will lead to reductions where
1500-518: A less specific "politically binding" agreement that would punt the most difficult issues into the future". Ministers and officials from 192 countries took part in the Copenhagen meeting and in addition there were participants from a large number of civil society organizations. As many Annex 1 industrialized countries are now reluctant to fulfill commitments under the Kyoto Protocol, a large part of

On Friday, 18 November 2016, the end of COP 22, the Chairperson of COP 23 from Fiji announced that it would be held in Bonn, Germany . (COP 23/CMP 13). Fijian Prime Minister and incoming President of COP 23, Frank Bainimarama , on 13 April launched the logo for this year's United Nations Climate Change Conference, to be held at UN Campus, Bonn in November. This conference saw

#17328555655611800-501: A model that includes the price of carbon and greenhouse gases (GHG). In many schemes, organizations which do not pollute (and therefore have no obligations) may also trade permits and financial derivatives of permits. In some schemes, participants can bank allowances to use in future periods. In some schemes, a proportion of all traded permits must be retired periodically, causing a net reduction in emissions over time. Thus, environmental groups may buy and retire permits, driving up
1950-410: A particular objective. Coase's model assumes perfectly operating markets and equal bargaining power among those arguing for property rights. In Coase's model, efficiency, i.e., achieving a given reduction in emissions at lowest cost, is promoted by the market system. This can also be looked at from the perspective of having the greatest flexibility to reduce emissions. Flexibility is desirable because
2100-427: A polluter that affects water quality at a number of points has to hold a portfolio of licenses covering all relevant monitoring-points. In the above example, if country 2 wants to emit a unit of pollutant, it should purchase two permits: one for location 2 and one for location 3. Montgomery shows that, while both markets lead to efficient license allocation, the market in pollution-licenses is more widely applicable than
2250-424: A pre-sessional period from 26 November to 1 December 2019 with up to 25 000 delegates scheduled to attend. However, following the 2019 Chilean protests , Chilean President Sebastián Piñera announced Chile's withdrawal from hosting the summit in late October 2019. UN Climate Change Executive Secretary Patricia Espinosa stated that organizers were "exploring alternative hosting options". Then Spain offered, and
2400-419: A price on pollution (for example, see carbon price ), and so provide an economic incentive to reduce pollution beginning with the lowest-cost opportunities. By contrast, in a command-and-control approach, a central authority designates pollution levels each facility is allowed to emit. Cap and trade essentially functions as a tax where the tax rate is variable based on the relative cost of abatement per unit, and
2550-575: A rate which will cause no more than a specified increase at the pollution-level. For concreteness, consider the following model. As an example, consider three countries along a river (as in the fair river sharing setting). So the matrix H {\displaystyle H} in this case is a triangular matrix of ones. Each pollution-license for location i {\displaystyle i} permits its holder to emit pollutants that will cause at most this level of pollution at location i {\displaystyle i} . Therefore,
2700-554: A reduction, avoidance or removal of one metric tonne of carbon dioxide or its carbon dioxide-equivalent (CO 2 e). A variety of greenhouse gas reduction projects can qualify for offsets and credits depending on the scheme. Some include forestry projects that avoid logging and plant saplings, renewable energy projects such as wind farms , biomass energy , biogas digesters , hydroelectric dams , as well as energy efficiency projects. Further projects include carbon dioxide removal projects, carbon capture and storage projects, and
2850-547: A result, performance standards are likely to be more costly overall. The additional costs would be passed to end consumers. Apart from the dynamic development in carbon emission trading , other pollutants have also been targeted. United Nations Climate Change conference The United Nations Climate Change Conferences are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change (UNFCCC). They serve as
3000-578: A separate decision of the Conference of Parties, countries agreed to a range of national security exemptions which stated that bunker fuels and emissions from multilateral military operations would not be part of national emissions totals and would be reported outside of those totals. Most industrialized countries and some central European economies in transition (all defined as Annex B countries) agreed to legally binding reductions in greenhouse gas emissions of an average of 6 to 8% below 1990 levels between
3150-407: A sufficient number of permits in system. Some analysts argue that allowing others to participate in trading, e.g., private brokerage firms, can allow for better management of risk in the system, e.g., to variations in permit prices (Bashmakov et al. , 2001). It may also improve the efficiency of system. According to Bashmakov et al . (2001), regulation of these other entities may be necessary, as
SECTION 20
#17328555655613300-410: A surcharge on the pollution created while producing goods and services. For example, a carbon tax is a tax on the carbon content of fossil fuels that aims to discourage their use and thereby reduce carbon dioxide emissions. The two approaches are overlapping sets of policy designs. Both can have a range of scopes, points of regulation, and price schedules. They can be fair or unfair, depending on how
3450-569: A time when it is most efficient to do so. One of the advantages of Coase's model is that it suggests that fairness (equity) can be addressed in the distribution of property rights, and that regardless of how these property rights are assigned, the market will produce the most efficient outcome. In reality, according to the held view, markets are not perfect, and it is therefore possible that a trade-off will occur between equity and efficiency (Halsnæs et al ., 2007). In an emissions trading system, permits may be traded by emitters who are liable to hold
3600-581: A timeline and structured negotiation on the post-2012 framework (the end of the first commitment period of the Kyoto Protocol) was achieved with the adoption of the Bali Action Plan (Decision 1/CP.13). The Ad Hoc Working Group on Long-term Cooperative Action under the Convention (AWG-LCA) was established as a new subsidiary body to conduct the negotiations aimed at urgently enhancing the implementation of
3750-511: A wide price range from €7 per tonne of CO 2 in China's national carbon trading scheme to €63 per tonne of CO 2 in the EU-ETS (as of September 2021). Other greenhouse gases can also be traded but are quoted as standard multiples of carbon dioxide with respect to their global warming potential . The economic problem with climate change is that the emitters of greenhouse gases (GHGs) do not face
3900-438: A world of uncertainty, it is not clear whether emissions fees or cap-and-trade systems are more efficient—it depends on how fast the marginal social benefits of reducing pollution fall with the amount of cleanup (e.g., whether inelastic or elastic marginal social benefit schedule). Other: The magnitude of the tax will depend on how sensitive the supply of emissions is to the price. The permit price of cap-and-trade will depend on
4050-498: Is a carbon trading mechanism that enables entities to compensate for offset greenhouse gas emissions by investing in projects that reduce, avoid, or remove emissions elsewhere. When an entity invests in a carbon offsetting program, it receives carbon credit or offset credit, which account for the net climate benefits that one entity brings to another. After certification by a government or independent certification body, credits can be traded between entities. One carbon credit represents
4200-455: Is a price instrument because it fixes the price while the emission level is allowed to vary according to economic activity. A major drawback of an emission tax is that the environmental outcome (e.g. a limit on the amount of emissions) is not guaranteed. On one hand, a tax will remove capital from the industry, suppressing possibly useful economic activity, but conversely, the polluter will not need to hedge as much against future uncertainty since
4350-535: Is a quantity control instrument. That is, a tax is a unit price for pollution that is set by authorities, and the market determines the quantity emitted; in cap and trade, authorities determine the amount of pollution, and the market determines the price. This difference affects a number of criteria. Responsiveness to inflation: Cap-and-trade has the advantage that it adjusts to inflation (changes to overall prices) automatically, while emissions fees must be changed by regulators. Responsiveness to cost changes: It
4500-514: Is determined by reference to the participant's historical emissions. To demonstrate compliance, a participant must hold permits at least equal to the quantity of pollution it actually emitted during the time period. If every participant complies, the total pollution emitted will be at most equal to the sum of individual limits. Because permits can be bought and sold, a participant can choose either to use its permits exactly (by reducing its own emissions); or to emit less than its permits, and perhaps sell
4650-469: Is different for regional pollutants (e.g. SO 2 and NO x , and also mercury ) because the impact of these pollutants may differ by location. The same amount of a regional pollutant can exert a very high impact in some locations and a low impact in other locations, so it matters where the pollutant is released. This is known as the Hot Spot problem. A Lagrange framework is commonly used to determine

4800-411: Is done in other financial markets , e.g., to prevent abuses of the system, such as insider trading . Emissions trading gives polluters an incentive to reduce their emissions. However, there are possible perverse incentives that can exist in emissions trading. Allocating permits on the basis of past emissions ("grandfathering") can result in firms having an incentive to maintain emissions. For example,
4950-505: Is due to report in November 2010. The negotiations on extending the Kyoto Protocol had unresolved issues as did the negotiations on a framework for long-term cooperative action. The working groups on these tracks to the negotiations are now due to report to COP 16 and CMP 6 in Mexico. COP 16 was held in Cancún , Mexico, from 28 November to 10 December 2010. The outcome of the summit
5100-409: Is essentially an emission cap and permit trading system but the maximum (or minimum) permit price is capped. Emitters have the choice of either obtaining permits in the marketplace or buying them from the government at a specified trigger price (which could be adjusted over time). The system is sometimes recommended as a way of overcoming the fundamental disadvantages of both systems by giving governments
5250-463: Is in contrast to command-and-control environmental regulations such as best available technology (BAT) standards and government subsidies . Pollution is a prime example of a market externality. An externality is an effect of some activity on an entity (such as a person) that is not party to a market transaction related to that activity. Emissions trading is a market-based approach to address pollution. The overall goal of an emissions trading plan
5400-460: Is not clear which approach is better. It is possible to combine the two into a safety valve price: a price set by regulators, at which polluters can buy additional permits beyond the cap. Responsiveness to recessions: This point is closely related to responsiveness to cost changes, because recessions cause a drop in demand. Under cap and trade, the emissions cost automatically decreases, so a cap-and-trade scheme adds another automatic stabilizer to
5550-496: Is possible for a country to reduce emissions using a command-and-control approach, such as regulation, direct and indirect taxes . The cost of that approach differs between countries because the Marginal Abatement Cost Curve (MAC)—the cost of eliminating an additional unit of pollution—differs by country. Coase (1960) argued that social costs could be accounted for by negotiating property rights according to
5700-405: Is that they might be used as a disguise for trade protectionism . Some types of border adjustment may also not prevent emissions leakage. The EU Carbon Border Adjustment Mechanism takes in effect for 6 sectors in 2026. The Paris Agreement provided a legal base for the creation of a global carbon market, which has a potentially significant role in stopping climate change. In the beginning of 2024,
5850-401: Is the traditional approach to reducing air pollution. Command-and-control regulations are more rigid than incentive-based approaches such as pollution fees and cap and trade. An example of this is a performance standard which sets an emissions goal for each polluter that is fixed and, therefore, the burden of reducing pollution cannot be shifted to the firms that can achieve it more cheaply. As
6000-446: Is to minimize the cost of meeting a set emissions target . In an emissions trading system, the government sets an overall limit on emissions, and defines permits (also called allowances), or limited authorizations to emit, up to the level of the overall limit. The government may sell the permits, but in many existing schemes, it gives permits to participants (regulated polluters) equal to each participant's baseline emissions. The baseline
6150-520: Is urgent, as with greenhouse gas emissions. A price floor also provides certainty and stability for investment in emissions reductions: recent experience from the UK shows that nuclear power operators are reluctant to invest on "un-subsidised" terms unless there is a guaranteed price floor for carbon (which the EU emissions trading scheme does not presently provide). Responsiveness to uncertainty: As with cost changes, in

6300-556: The European Union Emissions Trading System (EU-ETS) complement the country-to-country trading stipulated in the Kyoto Protocol by allowing private trading of permits, coordinating with national emissions targets provided under the Kyoto Protocol. Under such programmes, a national or international authority allocates permits to individual companies based on established criteria, with a view to meeting targets at
6450-588: The New South Wales (NSW) state government unilaterally established the New South Wales Greenhouse Gas Abatement Scheme to reduce emissions by requiring electricity generators and large consumers to purchase NSW Greenhouse Abatement Certificates (NGACs). This has prompted the rollout of free energy-efficient compact fluorescent lightbulbs and other energy-efficiency measures, funded by the credits. This scheme has been criticised by
6600-548: The Paris Agreement , with schemes operational in China , the European Union , and other countries. Emissions trading sets a quantitative total limit on the emissions produced by all participating emitters, which correspondingly determines the prices of emissions. Under emission trading, a polluter having more emissions than their quota has to purchase the right to emit more from emitters with fewer emissions. This can reduce

In advance to the conference, Pope Francis issued an apostolic exhortation called Laudate Deum in which he calls for brisk action against the climate crisis and condemns climate change denial . At the beginning of November 2023, the Pope announced he would attend the conference and would stay there for 3 days, but unfortunately he had to cancel his trip due to health issues. Charles III , King of
6900-412: The cap-and-trade variant of emissions trading, a cap on access to a resource is defined and then allocated among users in the form of permits. Compliance is established by comparing actual emissions with permits surrendered. The setting of the cap affects the environmental integrity of carbon trading, and can result in both positive and negative environmental effects. Emissions trading programmes such as
7050-452: The external costs of their actions, which include the present and future welfare of people, the natural environment, and the social cost of carbon . This can be addressed with the dynamic price model of emissions trading. An emissions trading scheme for greenhouse gas emissions (GHGs) works by establishing property rights for the atmosphere . The atmosphere is a global public good , and GHG emissions are an international externality . In
7200-421: The marginal costs, that is to say, the incremental costs of reducing emissions, varies among countries. Emissions trading allows emission reductions to be first made in locations where the marginal costs of abatement are lowest (Bashmakov et al ., 2001). Over time, efficiency can also be promoted by allowing "banking" of permits (Goldemberg et al ., 1996, p. 30). This allows polluters to reduce emissions at
7350-566: The Buenos Aires Plan of Action was adopted. The parties also began discussing the post-Kyoto mechanism, on how to allocate emission reduction obligation following 2012, when the first commitment period ends. COP 11/CMP 1 took place between 28 November and 9 December 2005, in Montreal , Quebec, Canada. It was the first C onference of the Parties serving as the M eeting of the Parties to

#17328555655617800-470: The Convention. The COP 8 was marked by Russia's hesitation, stating that it needed more time to think it over. The Kyoto Protocol could enter into force once it was ratified by 55 countries, including countries responsible for 55 per cent of the developed world's 1990 carbon dioxide emissions. With the United States (36.1 per cent share of developed-world carbon dioxide) and Australia refusing ratification, Russia's agreement (17% of global emissions in 1990)
7950-545: The EU ETS, where industries that have been judged to be internationally exposed have been given permits for free. The International Air Transport Association , whose 230 member airlines comprise 93% of all international traffic, argue that emissions levels should be based on industry averages rather than using individual companies' previous emissions levels to set their future permit allowances, stating that "would penalise airlines that took early action to modernise their fleets, while

8400-502: The Kyoto Protocol due to the surplus of allowances that some countries possess. For example, Russia had a surplus of allowances due to its economic collapse following the end of the Soviet Union. Other countries could have bought these allowances from Russia, but this would not have reduced emissions. In practice, as of 2010, Kyoto Parties had not yet chosen not to buy these surplus allowances. The complexity of cap and trade schemes around
8550-597: The Liberals opposed the ETS. This left the Rudd Labor government unable to secure passage of the bill, and it was subsequently withdrawn. Julia Gillard defeated Rudd in a leadership challenge, becoming Federal Prime Minister in June 2010. She promised that she would not introduce a carbon tax, but would look to legislate a price on carbon when taking the government to the 2010 election . In

Any final text of a COP must be agreed by consensus. The first UN Climate Change Conference
8850-755: The UNFCCC's charter). The conference was held in Warsaw , Poland from 11 to 23 November 2013. The most prominent result was the adoption of the Warsaw Framework for REDD-plus. The Conference also established the Warsaw International Mechanism (WIM) for Loss and Damage associated with Climate Change Impacts (Loss and Damage Mechanism), to address loss and damage associated with impacts of climate change. This included extreme events and slow onset events, in developing countries that are particularly vulnerable to
9000-539: The United States' proposal to allow credit for carbon "sinks" in forests and agricultural lands that would satisfy a major proportion of the U.S. emissions reductions in this way; disagreements over consequences for non-compliance by countries that did not meet their emission reduction targets; and difficulties in resolving how developing countries could obtain financial assistance to deal with adverse effects of climate change and meet their obligations to plan for measuring and possibly reducing greenhouse gas emissions. In
9150-549: The actual reductions achieved. To be credible, the reduction in emissions must meet three criteria: they must last indefinitely, be additional to emission reductions that were going to happen anyway, and must be measured, monitored and verified by independent third parties to ensure that the amount of reduction promised has in fact been attained. A domestic carbon emissions trading scheme is constrained in its regulatory jurisdiction. GHG emissions may thus leak to another region or sector with less regulation. Generally, leakages reduce

The burden of a volatile market will be borne by the controlling (taxing) agency rather than the industry itself, which is generally less efficient. An advantage is that, given a uniform tax rate and a volatile market, the taxing entity will not be in a position to pick "winners and losers" and the opportunity for corruption will be less.

9750-409: The certainty of a particular quantity limit of emissions. Emissions trading has been criticized for a variety of reasons. For one, it has been argued that climate change requires more radical solutions than pollution trading schemes, and that systemic changes must be made to reduce fossil fuel usage. At the same time, carbon credits have been seen as enabling large companies to pollute the environment at
9900-477: The change in regulations and not simply due to paying the real cost of carbon. However, if there is advanced notice of this change, or if the carbon price is introduced gradually, this one-time regulatory cost will be minimized. There has now been enough advance notice of carbon pricing that this effect should be negligible on average. Allocating permits based on past emissions is called "grandfathering". Grandfathering permits can lead to perverse incentives , such as
10050-746: The commitments of Annex I Parties in Article 4.2(a) and (b). Delegates also established: a pilot phase for Joint Implementation projects; an agreement that the Permanent Secretariat should be located in Bonn, Germany; and the Subsidiary Bodies . Conference delegates did not reach consensus on the Rules of Procedures, and a decision on voting rules was deferred to COP 2. COP 2 took place from 8–19 July 1996 in Geneva , Switzerland. Its ministerial declaration

Instead, carbon emissions trading may accelerate investments into renewable energy , such as wind power and solar power . However, such schemes are usually not harmonized with defined carbon budgets that are required to maintain global warming below the critical thresholds of 1.5 °C or "well below" 2 °C, with oversupply leading to low prices of allowances with almost no effect on fossil fuel combustion. Emission trade allowances currently cover
10350-426: The controlling agency and the industry are equally efficient at adapting to volatile market conditions, the best choice depends on the sensitivity of the costs of emission reduction, compared to the sensitivity of the benefits (i.e., climate damage avoided by a reduction) when the level of emission control is varied. A third option, known as a safety valve , is a hybrid of the price and quantity instruments. The system

Each abatement strategy was compared with the "least-cost solution" produced by a computer optimization program to identify the least-costly combination of source reductions in order to achieve a given abatement goal. In each case it was found that the least-cost solution was dramatically less costly than the same amount of pollution reduction produced by any conventional abatement strategy. Burton and later Sanjour along with Edward H. Pechan continued improving and advancing these computer models at
10650-728: The course of its history can be divided into four phases: In the United States, the acid rain related emission trading system was principally conceived by C. Boyden Gray , a G.H.W. Bush administration attorney. Gray worked with the Environmental Defense Fund (EDF), who worked with the EPA to write the bill that became law as part of the Clean Air Act of 1990. The new emissions cap on NO x and SO 2 gases took effect in 1995, and according to Smithsonian magazine, those acid rain emissions dropped 3 million tons that year. It
10800-619: The current market price of emission permits in Europe and the US. Countries face the permit market price that exists in the market that day, so they are able to make individual decisions that would minimize their costs while at the same time achieving regulatory compliance. This is also another version of the Equi-Marginal Principle , commonly used in economics to choose the most economically efficient decision. There has been longstanding debate on
10950-626: The differences that had produced an impasse in The Hague. However, this meeting took place after George W. Bush had become the President of the United States and had rejected the Kyoto Protocol in March 2001; as a result the United States delegation to this meeting declined to participate in the negotiations related to the Protocol and chose to take the role of observer at the meeting. As the other parties negotiated
11100-513: The diplomatic work that lays the foundation for a post-Kyoto agreement was undertaken up to the COP ;15. The conference did not achieve a binding agreement for long-term action. A 13-paragraph 'political accord' was negotiated by approximately 25 parties including US and China, but it was only 'noted' by the COP as it is considered an external document, not negotiated within the UNFCCC process. The accord
11250-426: The economy—in effect, an automatic fiscal stimulus. However, a lower pollution price also results in reduced efforts to reduce pollution. If the government is able to stimulate the economy regardless of the cap-and-trade scheme, an excessively low price causes a missed opportunity to cut emissions faster than planned. Instead, it might be better to have a price floor (a tax). This is especially true when cutting pollution
11400-723: The effectiveness of domestic emission abatement efforts. Notwithstanding, leakages may also be negative in nature, increasing the effectiveness of domestic abatement efforts. For example, a carbon tax applied only to developed countries might lead to a positive leakage to developing countries. However, a negative leakage might also occur due to technological developments driven by domestic regulation of GHGs, helping to reduce emissions even in less regulated regions. The current state of carbon emissions trading shows that roughly 22% of global greenhouse emissions are covered by 64 carbon taxes and emission trading systems as of 2021. Energy intensive industries that are covered by such instruments may view
11550-409: The efficiency of the economy. Form of allocation The economist Ross Garnaut states that permits allocated to existing emitters by 'grandfathering' are not 'free'. As the permits are scarce they have value and the benefit of that value is acquired in full by the emitter. The cost is imposed elsewhere in the economy, typically on consumers who cannot pass on the costs. Some economists have urged
11700-571: The election, and the new government proceeded to implement an ETS. The new Rudd government introduced the Carbon Pollution Reduction Scheme , which the Liberal Party of Australia (now led by Malcolm Turnbull ) supported. Tony Abbott questioned an ETS, advocating a "simple tax" as the best way to reduce emissions. Shortly before the carbon vote, Abbott defeated Turnbull in a leadership challenge (1 December 2009), and from there on
11850-461: The elimination of methane emissions in various settings such as landfills . Many projects that give credits for carbon sequestration have received criticism as greenwashing because they overstated their ability to sequester carbon, with some projects being shown to actually increase overall emissions. Carbon offset and credit programs provide a mechanism for countries to meet their Nationally Determined Contributions (NDC) commitments to achieve
12000-463: The end of the session, as they had a right to under the session's rules. In closing the conference, the President said that he would note these objections in his final report. COP 19 was the 19th yearly session of the Conference of the Parties (COP) to the 1992 United Nations Framework Convention on Climate Change (UNFCCC) and the 9th session of the Meeting of the Parties (CMP) to the 1997 Kyoto Protocol (the protocol having been developed under
12150-531: The event a special initiative on water was presided by Charafat Afailal, Morocco's Minister in Charge of Water and Aziz Mekouar, COP 22 Ambassador for Multilateral Negotiations. Another focal issue was the need to reduce greenhouse emissions and utilize low-carbon energy sources. Peter Thomson , President of the UN General Assembly, called for the transformation of the global economy in all sectors to achieve
12300-404: The excess permits; or to emit more than its permits, and buy permits from other participants. In effect, the buyer pays a charge for polluting, while the seller gains a reward for having reduced emissions. Emissions Trading results in the incorporation of economic costs into the costs of production which incentivizes corporations to consider investment returns and capital expenditure decisions with
12450-470: The expense of local communities. Carbon trading has also been criticised as a form of colonialism , in which rich countries maintain their levels of consumption while getting credit for carbon savings in inefficient industrial projects. Groups such as the Corner House have argued that the market will choose the easiest means to save a given quantity of carbon in the short term, which may be different from
12600-471: The final hours of COP 6, despite some compromises agreed between the United States and some EU countries, notably the United Kingdom, the EU countries as a whole, led by Denmark and Germany, rejected the compromise positions, and the talks in The Hague collapsed. Jan Pronk , the President of COP 6, suspended COP 6 without agreement, with the expectation that negotiations would later resume. It
12750-519: The first Australian hung-parliament result in 70 years, the Gillard Labor government required the support of crossbenchers - including the Greens . One requirement for Greens' support was a carbon price, which Gillard proceeded with in forming a minority government. A fixed carbon-price would proceed to a floating-price ETS within a few years under the plan. The fixed price lent itself to characterisation as
12900-428: The flexibility to adjust the system as new information comes to light. It can be shown that by setting the trigger price high enough, or the number of permits low enough, the safety valve can be used to mimic either a pure quantity or pure price mechanism. Cap and trade is the textbook example of an emissions trading program . Other market-based approaches include baseline-and-credit , and pollution tax . They all put
13050-516: The formal meeting of the UNFCCC parties – the Conference of the Parties (COP) – to assess progress in dealing with climate change , and beginning in the mid-1990s, to negotiate the Kyoto Protocol to establish legally binding obligations for developed countries to reduce their greenhouse gas emissions . Starting in 2005 the conferences have also served as the "Conference of the Parties Serving as
13200-407: The full marginal social costs of their actions. Regulation of emissions applied only to one economic sector or region drastically reduces the efficiency of efforts to reduce global emissions. There is, however, no scientific consensus over how to share the costs and benefits of reducing future climate change, or the costs and benefits of adapting to any future climate change. Carbon offsetting
13350-406: The full value of its free permits. Grandfathering may also slow down technological development towards less polluting technologies. The Garnaut Report noted that any method for free permit allocation will have the disadvantages of high complexity, high transaction costs, value-based judgements, and the use of arbitrary emissions baselines. Garnaut also noted that the complexity of free allocation and
13500-518: The global value of carbon markets was $ 948.75 billion. It is expected to reach 2.68 trillion dollars by 2028 and 22 trillion by 2050. Tradable emissions permits can be issued to firms within an ETS by two main ways: by free allocation of permits to existing emitters or by auction. In the first case, the government receives no carbon revenue. In the second it receives the full value of the permits, on average. In either case, permits will be equally scarce and just as valuable to market participants, such that
13650-680: The goals of the Paris Agreement . Article 6 of the Paris Agreement includes three mechanisms for "voluntary cooperation" between countries towards climate goals, including carbon markets . Article 6.2 enabled countries to directly trade carbon credits and units of renewable power with each other. Article 6.4 established a new international carbon market allowing countries or companies to use carbon credits generated in other countries to help meet their climate targets. Carbon offset and credit programs are coming under increased scrutiny because their claimed emissions reductions may be inflated compared to
13800-468: The greenhouse gas emissions reduction obligation, the first two non-Annex countries to do so. COP 5 took place between 25 October and 5 November 1999, in Bonn , Germany. It was primarily a technical meeting, and did not reach major conclusions. 165 Parties were represented at the conference. Conference delegates continued their work toward fulfilling the Buenos Aires Plan of Action (BAPA) adopted at COP 4. In
13950-572: The idea made some progress, as in the Bonn meeting new tools and supervisory bodies was created. The rules of the European Union Emissions Trading System include the possibility of connecting it with other trading systems. This has already happened with the Switzerland emissions trading system . China expressed a support for a global carbon market, saying it is better than the EU Carbon Border Adjustment Mechanism . In 2023
14100-463: The industry must accordingly bear the cost of adapting to these volatile market conditions. The burden of a volatile market thus lies with the industry rather than the controlling agency, which is generally more efficient. However, under volatile market conditions, the ability of the controlling agency to alter the caps will translate into an ability to pick "winners and losers" and thus presents an opportunity for corruption. In contrast, an emission tax
14250-547: The key issues, agreement was reached on most of the major political issues, to the surprise of most observers, given the low expectations that preceded the meeting. The agreements included: A number of operational details attendant upon these decisions remained to be negotiated and agreed upon, and these were the major issues considered by the COP 7 meeting that followed. At the COP 7 meeting in Marrakech , Morocco, from 29 October to 10 November 2001, negotiators wrapped up
14400-466: The large amounts of money involved encourage non-productive rent-seeking behaviour and lobbying of governments — activities that dissipate economic value. At the same time, allocating permits can be used as a measure to protect domestic firms who are internationally exposed to competition. This happens when domestic firms compete against other firms that are not subject to the same regulation. This argument in favor of allocation of permits has been used in
14550-526: The last two days of the Conference, COP 5 adopted 32 draft decisions and conclusions related to the review of the implementation of commitments. Despite reaching no major conclusions, COP-5 served as an important "intermediate step" laying out the difficult path to finalizing the Kyoto Protocol at COP-6. COP 6 took place on 13–25 November 2000, in The Hague , Netherlands. Many in the international community and domestic environmental groups saw this meeting as
14700-581: The launch of the Powering Past Coal Alliance . COP 24 was held on 3–14 December 2018 in Katowice , Poland. The Polish government's vision for presidency states that the organisation of COP 24 will provide an opportunity for convincing other countries that Poland does not hamper the process of tackling dangerous climate change and that Poland is one of the leaders of this process. The Climate Change Conference of UNFCCC Subsidiary Bodies
14850-518: The least cost of achieving an objective, in this case the total reduction in emissions required in a year. In some cases, it is possible to use the Lagrange optimization framework to determine the required reductions for each country (based on their MAC) so that the total cost of reduction is minimized. In such a scenario, the Lagrange multiplier represents the market allowance price (P) of a pollutant, such as
15000-406: The least expensive solutions exist, while allowing emissions that are more expensive to reduce. Under an emissions trading system, each regulated polluter has flexibility to use the most cost-effective combination of buying or selling emission permits, reducing its emissions by installing cleaner technology, or reducing its emissions by reducing production. The most cost-effective strategy depends on
15150-511: The life of the Kyoto Protocol beyond its 2012 expiration date and negotiate deeper cuts in greenhouse-gas emissions". Canada's environment minister at the time, Stéphane Dion , said the agreement provides a "map for the future". COP 12/CMP 2 took place on 6–17 November 2006 in Nairobi , Kenya. At the meeting, BBC reporter Richard Black coined the phrase "climate tourists" to describe some delegates who attended "to see Africa, take snaps of
15300-420: The local regulator. Enforcement methods include fines and sanctions for polluters that have exceeded their allowances. Concerns include the cost of MRV and enforcement, and the risk that facilities may lie about actual emissions. An emission license directly confers a right to emit pollutants up to a certain rate. In contrast, a pollution license for a given location confers the right to emit pollutants at
15450-588: The lowest overall economic cost. "Economy-wide pricing of carbon is the centre piece of any policy designed to reduce emissions at the lowest possible costs". Ross Garnaut , lead author of the Garnaut Climate Change Review in 2011 Carbon emission trading began in Rio de Janeiro in 1992, when 160 countries agreed the UN Framework Convention on Climate Change (UNFCCC). The necessary detail
15600-412: The market in emission-licenses. The nature of the pollutant plays a very important role when policy-makers decide which framework should be used to control pollution. CO 2 acts globally, thus its impact on the environment is generally similar wherever in the globe it is released. So the location of the originator of the emissions does not matter from an environmental standpoint. The policy framework
15750-588: The means to reduce climate change. In September 2010, campaigning group FERN released "Trading Carbon: How it works and why it is controversial" which compiles many of the arguments against carbon trading. According to Carbon Trade Watch, carbon trading has had a "disastrous track record". The effectiveness of the EU ETS was criticized, and it was argued that the CDM had routinely favoured "environmentally ineffective and socially unjust projects". Some groups have claimed that non-existent emission reductions can be recorded under
15900-436: The new, non-zero cost of emissions. This gives permit-liable polluters an incentive to reduce their emissions. However, if a firm sells the same amount of output as before that cap, with no change in production technology, the full value of permits received for free becomes windfall profits . However, since the cap reduces output and often causes the company to incur costs to increase efficiency, windfall profits will be less than
16050-408: The newly created U.S. Environmental Protection Agency. The agency introduced the concept of computer modeling with least-cost abatement strategies (i.e., emissions trading) in its 1972 annual report to Congress on the cost of clean air. This led to the concept of "cap and trade" as a means of achieving the "least-cost solution" for a given level of abatement. The development of emissions trading over
16200-408: The parties also agreed to review the first national reports submitted by 110 non-Annex I countries. COP 10 took place on 6–17 December 2004. COP 10 discussed the progress made since the first Conference of the Parties 10 years ago and its future challenges, with special emphasis on climate change mitigation and adaptation. To promote developing countries better adapt to climate change,
16350-400: The period post 2020. There was also progress regarding the creation of a Green Climate Fund (GCF) for which a management framework was adopted. The fund is to distribute US$ 100 billion per year to help poor countries adapt to climate impacts. While the president of the conference, Maite Nkoana-Mashabane , declared it a success, scientists and environmental groups warned that the deal
16500-473: The permit revenue. Auctions of units are more flexible in distributing costs, provide more incentives for innovation, lessen the political arguments over the allocation of economic rents , and reduce tax distortions. Recycling of revenue from permit auctions could also offset a significant proportion of the economy-wide social costs of a cap and trade scheme. The perverse incentive of grandfathering can be alleviated through auctioning. Regulatory agencies run
16650-425: The permits are scarce, they have value, and the benefit of that value is acquired in full by the emitter. The cost is imposed elsewhere in the economy, typically on consumers who cannot pass on the costs: The cost of a grandfathered permit may be regarded as the opportunity cost of not selling the permit at full value. As a result, profit-maximising firms receiving free permits will raise prices to customers because of
16800-468: The pollutant market. A tax generates government revenue, but full-auctioned emissions permits can do the same. A similar upstream cap-and-trade system could be implemented. An upstream carbon tax might be the simplest to administer. Setting up a complex cap-and-trade arrangement that is comprehensive has high institutional needs. Command and control is a system of regulation that prescribes emission limits and compliance methods for each facility or source. It
16950-710: The polluter is being paid to reduce emissions (Goldemberg et al ., 1996, p. 38). On the other hand, a permit system where permits are auctioned rather than given away, provides the government with revenues. These revenues might be used to improve the efficiency of overall climate policy, e.g., by funding energy efficiency programs (ACEEE 2019) or reductions in distortionary taxes (Fisher et al ., 1996, p. 417). In Coase's model of social costs, either choice (grandfathering or auctioning) leads to efficiency. In reality, grandfathering subsidizes polluters, meaning that polluting industries may be kept in business longer than would otherwise occur. Grandfathering may also reduce
17100-685: The polluter's marginal abatement cost and the market price of permits. In theory, a polluter's decisions should lead to an economically efficient allocation of reductions among polluters, and lower compliance costs for individual firms and for the economy overall, compared to command-and-control mechanisms. In some industrial processes, emissions can be physically measured by inserting sensors and flowmeters in chimneys and stacks, but many types of activity rely on theoretical calculations instead of measurement. Depending on local legislation, measurements may require additional checks and verification by government or third party auditors , prior or post submission to
17250-571: The poorest nations cope with the effects of climate change and they approved a mechanism to incorporate forest protection into the efforts of the international community to combat climate change. Negotiations on a successor to the Kyoto Protocol were the primary focus of the conference. COP 15 took place in Copenhagen , Denmark , on 7–18 December 2009. The overall goal for the COP 15/CMP 5 United Nations Climate Change Conference in Denmark
17400-866: The potential of creating a new speculative market through the commodification of environmental risks through financial derivatives . Annie Leonard 's 2009 documentary The Story of Cap and Trade criticized carbon emissions trading for the free permits to major polluters giving them unjust advantages, cheating in connection with carbon offsets , and as a distraction from the search for other solutions. In China, some companies started artificial production of greenhouse gases with sole purpose of recycling and gaining carbon credits. Similar practices happened in India. Earned credit were then sold to companies in US and Europe. Corporate and governmental carbon emission trading schemes have been modified in ways that have been attributed to permitting money laundering to take place. In 2003
17550-414: The price at sale will be the same in either case. Generally, emitters will profit from permits allocated to them for free. But if they must pay, their profits will be reduced. If the carbon price equals the true social cost of carbon, then long-run profit reduction will reflect the consequences of paying this new cost. If having to pay this cost is unexpected, then there will likely be a one-time loss due to
17700-538: The price of the remaining permits according to the law of demand . In most schemes, permit owners can donate permits to a nonprofit entity and receive a tax deductions . Usually, the government lowers the overall limit over time, with an aim towards a national emissions reduction target. There are active trading programs in several air pollutants . An earlier application was the US national market to reduce acid rain . The United States now has several regional markets in nitrogen oxides . The efficiency of what later
17850-527: The process at some point and worked to achieve ratification of the Kyoto Protocol by the requisite number of countries to bring it into force (55 countries needed to ratify it, including those accounting for 55% of developed-country emissions of carbon dioxide in 1990). The date of the World Summit on Sustainable Development (August–September 2002) was put forward as a target to bring the Kyoto Protocol into force. The World Summit on Sustainable Development (WSSD)
18000-425: The rate of technological improvement towards less polluting technologies (Fisher et al. , 1996, p. 417). William Nordhaus argues that allocations cost the economy as they cause the under utilisation an efficient form of taxation. Nordhaus argues that normal income, goods or service taxes distort efficient investment and consumption, so by using pollution taxes to generate revenue an emissions scheme can increase
18150-549: The regulatory disparity between jurisdictions as a loss of competitiveness. They may therefore make strategic production decisions that involve carbon leakage. To mitigate carbon leakage and its effects on the environment, policymakers need to harmonize international climate policies and provide incentives to prevent companies from relocating production to regions with more lenient environmental regulations. Free emission permits, given to sectors vulnerable to international competition, are one way of addressing carbon leakage by acting as
18300-440: The relative merits of price versus quantity instruments to achieve emission reductions. An emission cap and permit trading system is a quantity instrument because it fixes the overall emission level (quantity) and allows the price to vary. Uncertainty in future supply and demand conditions (market volatility ) coupled with a fixed number of pollution permits creates an uncertainty in the future price of pollution permits, and
18450-443: The remaining issues unresolved in Kyoto would be finalized at this meeting. However, the complexity and difficulty of finding agreement on these issues proved insurmountable, and instead the parties adopted a two-year "Buenos Aires Plan of Action" (BAPA) to advance efforts and to devise mechanisms for implementing the Kyoto Protocol, to be completed by 2000. During COP 4, Argentina and Kazakhstan expressed their commitment to take on
18600-402: The revenue is used. Both have the effect of increasing the price of goods (such as fossil fuels) to consumers. A comprehensive, upstream, auctioned cap-and-trade system is very similar to a comprehensive, upstream carbon tax. Yet, many commentators sharply contrast the two approaches. The main difference is what is defined and what derived. A tax is a price control, while a cap-and-trade system
18750-419: The risk of issuing too many emission credits, which can result in a very low price on emission permits. This reduces the incentive that permit-liable firms have to cut back their emissions. On the other hand, issuing too few permits can result in an excessively high permit price. An argument has been made for a hybrid instrument having a price floor and a price ceiling. However, a price-ceiling safety value removes
18900-707: The start of the Chinese national carbon trading scheme . The increasing costs of permits on the EU ETS have had the effect of increasing costs of coal power. A 2019 study by the American Council for an Energy Efficient Economy finds that efforts to put a price on greenhouse gas emissions are growing in North America. In 2021, shipowners said they were against being included in the EU ETS. Economists generally agree that to regulate emissions efficiently, all polluters need to face
19050-399: The tax base is variable based on the amount of abatement needed. In a baseline and credit program, polluters can create permits, called credits or offsets, by reducing their emissions below a baseline level, which is often the historical emissions level from a designated past year. Such credits can be bought by polluters that have a regulatory limit. Emissions fees or environmental tax is
19200-561: The threshold for adoption was reached with over 55 countries representing at least 55% of the world's greenhouse gas emissions ratifying the Agreement. COP 22 was held in Marrakech , in the North African country of Morocco, on 7–18 November 2016. A focal issue of COP 22 is that of water scarcity , water cleanliness, and water-related sustainability , a major problem in the developing world , including many African states. Prior to
19350-432: The time frame for peaking will be longer in developing countries, since social and economic development and poverty eradication are the first and overriding priorities of developing countries . The 2011 COP 17 was held in Durban, South Africa , from 28 November to 9 December 2011. The conference agreed to a start negotiations on a legally binding deal comprising all countries, to be adopted in 2015, governing
19500-483: The use of coal-fired power stations . COP 27 was originally expected to take place in November 2021, but was moved to 2022 due to the rescheduling of COP 26 from 2020 to 2021. It took place in Sharm El Sheikh , Egypt. It led to an agreement on loss and damage , under which rich countries could compensate poor countries for damage caused by climate change. COP 28 took place at Expo City Dubai, in
19650-547: The use of market-based instruments such as emissions trading to address environmental problems instead of prescriptive "command-and-control" regulation. Command and control regulation is criticized for being insensitive to geographical and technological differences, and therefore inefficient; however, this is not always so, as shown by the WWII rationing program in the U.S. in which local and regional boards made adjustments for these differences. After an emissions limit has been set by
19800-414: The wildlife, the poor, dying African children and women". Black also noted that due to delegates concerns over economic costs and possible losses of competitiveness, the majority of the discussions avoided any mention of reducing emissions. Black concluded that was a disconnect between the political process and the scientific imperative. Despite such criticism, certain strides were made at COP12, including in
19950-539: The work on the Buenos Aires Plan of Action, finalizing most of the operational details and setting the stage for nations to ratify the Kyoto Protocol. The completed package of decisions is known as the Marrakech Accords . The United States delegation maintained its observer role, declining to participate actively in the negotiations. Other parties continued to express hope that the United States would re-engage in
20100-472: The world has resulted in the uncertainties around such schemes in Australia, Canada, China, the EU, India, Japan, New Zealand, and the US. As a result, some organizations have had little incentive to innovate and comply, resulting in an ongoing battle of stakeholder contestation for the past two decades. Proposals for alternative schemes to avoid the problems of cap-and-trade schemes include Cap and Share , which
20250-458: The years 2008–2012, defined as the first emissions budget period. The United States would be required to reduce its total emissions an average of 7% below 1990 levels; however Congress did not ratify the treaty after Clinton signed it. The Bush administration explicitly rejected the protocol in 2001. COP 4 took place on 2–14 November 1998 in Buenos Aires , Argentina. It had been expected that
20400-532: Was an agreement adopted by the states' parties that called for the US$ 100 billion per annum " Green Climate Fund ", and a "Climate Technology Centre" and network. However the funding of the Green Climate Fund was not agreed upon. Nor was a commitment to a second period of the Kyoto Protocol agreed upon, but it was concluded that the base year shall be 1990 and the global warming potentials shall be those provided by
20550-646: Was appointed, as the new host. COP 26 was originally scheduled to take place from 9 to 19 November 2020, in Glasgow , United Kingdom, but was postponed to 31 October to 12 November 2021 due to the COVID-19 pandemic . Among other things, this conference led to the development of the Accelerating to Zero coalition to accelerate the phase-out of fossil fuel vehicles , and the Glasgow Climate Pact to "phase down"
20700-561: Was considered by the Irish Parliament in 2008, and the Sky Trust schemes. Carbon emission trading without border adjustments for exports leads to reduced global competitiveness for carbon-intensive products. The Financial Times published an article about cap-and-trade systems, which argued that "Carbon markets create a muddle" and "...leave much room for unverifiable manipulation". Emissions trading schemes have also been criticised for
20850-602: Was convened in Bonn, Germany, from 17 to 27 June 2019. The 25th session of the Conference of the Parties (COP 25) to the UNFCCC was planned to take place from 11 to 22 November 2019 in Brazil. Upon election as President of Brazil, Jair Bolsonaro withdrew Brazil from hosting the event. COP 25 was then planned to take place in Parque Bicentenario Cerrillos in Santiago de Chile, Chile from 2 to 13 December with
21000-496: Was held in Paris from 30 November to 12 December 2015. Negotiations resulted in the adoption of the Paris Agreement on 12 December, governing climate change reduction measures from 2020. The adoption of this agreement ended the work of the Durban platform, established during COP 17. The agreement entered into force (and thus become fully effective) on 4 November 2016. On 4 October 2016
21150-531: Was held in 1995 in Berlin. The first UNFCCC Conference of the Parties took place from 28 March to 7 April 1995 in Berlin , Germany. Delegates from 117 Parties and 53 Observer States attended the conference. One of the central issues of COP 1 was the adequacy of individual country commitments, resulting in a mandate to begin a process toward individual country action for the period beyond 2000. This included strengthening
21300-472: Was later announced that the COP 6 meetings (termed "COP 6 bis") would be resumed in Bonn , Germany, in the second half of July. The next regularly scheduled meeting of the parties to the UNFCCC, COP 7, had been set for Marrakech, Morocco , in October–November 2001. COP 6 negotiations resumed on 16–27 July 2001, in Bonn , Germany, with little progress having been made in resolving
21450-484: Was left to be settled by the UN Conference of Parties (COP). In 1997, the Kyoto Protocol was the first major agreement to reduce greenhouse gases. 38 developed countries committed themselves to targets and timetables. The resulting inflexible limitations on GHG growth could entail substantial costs if countries have to solely rely on their own domestic measures. Carbon emissions trading increased rapidly in 2021 with
21600-568: Was not sufficient to avoid global warming beyond 2 °C as more urgent action is needed. Qatar hosted COP 18 which took place in Doha , Qatar, from 26 November to 7 December 2012. The Conference produced a package of documents collectively titled The Doha Climate Gateway . The documents collectively contained: The conference made little progress towards the funding of the Green Climate Fund . Russia, Belarus and Ukraine objected at
21750-488: Was notable in that it referred to a collective commitment by developed countries for new and additional resources, including forestry and investments through international institutions, that will approach US$ 30 billion for the period 2010–2012. Longer-term options on climate financing mentioned in the accord are being discussed within the UN Secretary General's High Level Advisory Group on Climate Financing , which
21900-704: Was noted (but not adopted) on 18 July 1996, and reflected a United States position statement presented by Timothy Wirth , former Under Secretary for Global Affairs for the United States Department of State at that meeting, which: COP 3 took place on 1–11 December 1997 in Kyoto , Japan. After intensive negotiations, it adopted the Kyoto Protocol , which outlined the greenhouse gas emissions reduction obligation for Annex I countries , along with what came to be known as Kyoto mechanisms such as emissions trading, clean development mechanism and joint implementation. In
22050-459: Was required to meet the ratification criteria and therefore Russia could delay the process. COP 9 took place on 1–12 December 2003 in Milan , Italy . The parties agreed to use the Adaptation Fund established at COP 7 in 2001 primarily in supporting developing countries better adapt to climate change. The fund would also be used for capacity-building through technology transfer. At COP 9,
22200-650: Was to be called the "cap-and-trade" approach to air pollution abatement was first demonstrated in a series of micro-economic computer simulation studies between 1967 and 1970 for the National Air Pollution Control Administration (predecessor to the United States Environmental Protection Agency 's Office of Air and Radiation) by Ellison Burton and William Sanjour . These studies used mathematical models of several cities and their emission sources in order to compare
22350-626: Was to be held in Johannesburg , South Africa. The main decisions at COP 7 included: Taking place from 23 October to 1 November 2002, in New Delhi COP ;8 adopted the Delhi Ministerial Declaration that, amongst others, called for efforts by developed countries to transfer technology and minimize the impact of climate change on developing countries. It is also approved the New Delhi work programme on Article 6 of
22500-472: Was to establish an ambitious global climate agreement for the period from 2012 when the first commitment period under the Kyoto Protocol expires. However, on 14 November 2009, the New York Times announced that "President Obama and other world leaders have decided to put off the difficult task of reaching a climate change agreement... agreeing instead to make it the mission of the Copenhagen conference to reach
