The Kyoto Protocol implemented the objective of the UNFCCC to reduce the onset of global warming by reducing greenhouse gas concentrations in the atmosphere to "a level that would prevent dangerous anthropogenic interference with the climate system" (Article 2).

, and therefore placed the obligation to reduce current emissions on developed countries on the basis that they are historically responsible for the current levels of greenhouse gases in the atmosphere. The Protocol's first commitment period started in 2008 and ended in 2012. All 36 countries that fully participated in the first commitment period complied with the Protocol. However, nine countries had to resort to the flexibility mechanisms by funding emission reductions in other countries because their national emissions were slightly greater than their targets. The

(UNFCCC) among other agreements. 1995 – Parties to the UNFCCC meet in Berlin (the 1st Conference of Parties (COP) to the UNFCCC) to outline specific targets on emissions. 1997 – In December the parties conclude the Kyoto Protocol in Kyoto, Japan, in which they agree to the broad outlines of emissions targets. 2004 – Russia and Canada ratify the Kyoto Protocol to the UNFCCC bringing the treaty into effect on 16 February 2005. 2011 – Canada became the first signatory to announce its withdrawal from the Kyoto Protocol. 2012 – On 31 December 2012, the first commitment period under the Protocol expired. The official meeting of all states party to the Kyoto Protocol is the annual Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). The first conference was held in 1995 in Berlin ( COP 1). The first Meeting of Parties of the Kyoto Protocol (CMP) was held in 2005 in conjunction with COP 11.


Objectives

The main goal of the Kyoto Protocol was to control emissions of the main anthropogenic (human-emitted) greenhouse gases (GHGs) in ways that reflect underlying national differences in GHG emissions, wealth, and capacity to make the reductions. The treaty follows the main principles agreed in the original 1992 UN Framework Convention. According to the treaty, in 2012, Annex I Parties who have ratified the treaty must have fulfilled their obligations of greenhouse gas emissions limitations established for the Kyoto Protocol's first commitment period (2008–2012). These emissions limitation commitments are listed in Annex B of the Protocol. The Kyoto Protocol's first round commitments are the first detailed step taken within the UN Framework Convention on Climate Change. The Protocol establishes a structure of rolling emission reduction commitment periods. It set a timetable starting in 2006 for negotiations to establish emission reduction commitments for a second commitment period. The first period emission reduction commitments expired on 31 December 2012. The first-round Kyoto emissions limitation commitments were not sufficient to stabilize the atmospheric concentration of GHGs. Stabilization of atmospheric GHG concentrations will require further emissions reductions after the end of the first-round Kyoto commitment period in 2012. , p.122, in The ultimate objective of the UNFCCC is the "stabilization of greenhouse gas concentrations in the atmosphere at a level that would stop dangerous anthropogenic interference with the climate system." Even if Annex I Parties succeed in meeting their first-round commitments, much greater emission reductions will be required in future to stabilize atmospheric GHG concentrations. For each of the different anthropogenic GHGs, different levels of emissions reductions would be required to meet the objective of stabilizing atmospheric concentrations.

() is the most important anthropogenic GHG. Stabilizing the concentration of in the atmosphere would ultimately require the effective elimination of anthropogenic emissions. To achieve stabilization, global GHG emissions must peak, then decline. , in The lower the desired stabilization level, the sooner this peak and decline must occur. For a given stabilization level, larger emissions reductions in the near term allow for less stringent emissions reductions later. , in On the other hand, less stringent near term emissions reductions would, for a given stabilization level, require more stringent emissions reductions later on. The first period Kyoto emissions limitations can be viewed as a first-step towards achieving atmospheric stabilization of GHGs. In this sense, the first period Kyoto commitments may affect what future atmospheric stabilization level can be achieved.


Principal concepts

Some of the principal concepts of the Kyoto Protocol are: * Binding commitments for the Annex I Parties. The main feature of the Protocol is that it established legally binding commitments to reduce emissions of greenhouse gases for Annex I Parties. The commitments were based on the Berlin Mandate, which was a part of UNFCCC negotiations leading up to the Protocol. * Implementation. In order to meet the objectives of the Protocol, Annex I Parties are required to prepare policies and measures for the reduction of greenhouse gases in their respective countries. In addition, they are required to increase the absorption of these gases and utilize all mechanisms available, such as joint implementation, the clean development mechanism and emissions trading, in order to be rewarded with credits that would allow more greenhouse gas emissions at home. * Minimizing Impacts on Developing Countries by establishing an
adaptation In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the p ...
fund for climate change. * Accounting, Reporting and Review in order to ensure the integrity of the Protocol. * Compliance. Establishing a Compliance Committee to enforce compliance with the commitments under the Protocol.


Flexibility mechanisms

The Protocol defines three " Flexibility Mechanisms" that can be used by Annex I Parties in meeting their emission limitation commitments. The flexibility mechanisms are International Emissions Trading (IET), the

, AAUs, or "allowances" for short). The economic basis for providing this flexibility is that the marginal cost of reducing (or abating) emissions differs among countries. , in "Marginal cost" is the cost of abating the last tonne of -eq for an Annex I/non-Annex I Party. At the time of the original Kyoto targets, studies suggested that the flexibility mechanisms could reduce the overall ( aggregate) cost of meeting the targets. , in Studies also showed that national losses in Annex I

(GDP) could be reduced by the use of the flexibility mechanisms. The CDM and JI are called "project-based mechanisms", in that they generate emission reductions from projects. The difference between IET and the project-based mechanisms is that IET is based on the setting of a quantitative restriction of emissions, while the CDM and JI are based on the idea of "production" of emission reductions. The CDM is designed to encourage production of emission reductions in non-Annex I Parties, while JI encourages production of emission reductions in Annex I Parties. The production of emission reductions generated by the CDM and JI can be used by Annex I Parties in meeting their emission limitation commitments. The emission reductions produced by the CDM and JI are both measured against a hypothetical baseline of emissions that would have occurred in the absence of a particular emission reduction project. The emission reductions produced by the CDM are called Certified emission reductions (CERs); reductions produced by JI are called emission reduction units (ERUs). The reductions are called " credits" because they are emission reductions credited against a hypothetical baseline of emissions. Only emission reduction projects that do not involve using nuclear energy are eligible for accreditation under the CDM, in order to prevent nuclear technology exports from becoming the default route for obtaining credits under the CDM. Each Annex I country is required to submit an annual report of inventories of all anthropogenic greenhouse gas emissions from sources and removals from sinks under UNFCCC and the Kyoto Protocol. These countries nominate a person (called a "designated national authority") to create and manage its
greenhouse gas inventory Greenhouse gas inventories are emission inventories of greenhouse gas emissions that are developed for a variety of reasons. Scientists use inventories of natural and anthropogenic (human-caused) emissions as tools when developing atmospheric m ...
. Virtually all of the non-Annex I countries have also established a designated national authority to manage their Kyoto obligations, specifically the "CDM process". This determines which GHG projects they wish to propose for accreditation by the CDM Executive Board.


International emissions trading


= Intergovernmental emissions trading

= The design of the European Union Emissions Trading Scheme (EU ETS) implicitly allows for trade of national Kyoto obligations to occur between participating countries. The Carbon Trust found that other than the trading that occurs as part of the EU ETS, no intergovernmental emissions trading had taken place. One of the environmental problems with IET is the large surplus of allowances that are available. Russia, Ukraine, and the new EU-12 member states (the Kyoto Parties Annex I Economies-in-Transition, abbreviated "EIT": Belarus, Bulgaria, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Russia, Slovakia, Slovenia, and Ukraine) have a surplus of allowances, while many

countries have a deficit. Some of the EITs with a surplus regard it as potential compensation for the trauma of their economic restructuring. When the Kyoto treaty was negotiated, it was recognized that emissions targets for the EITs might lead to them having an excess number of allowances. This excess of allowances were viewed by the EITs as "headroom" to grow their economies. The surplus has, however, also been referred to by some as "hot air", a term which Russia (a country with an estimated surplus of 3.1 billion tonnes of carbon dioxide equivalent allowances) views as "quite offensive". OECD countries with a deficit could meet their Kyoto commitments by buying allowances from transition countries with a surplus. Unless other commitments were made to reduce the total surplus in allowances, such trade would not actually result in emissions being reduced (see also the section below on the Green Investment Scheme).


= "Green Investment Schemes"

= The "Green Investment Scheme" (GIS) is a plan for achieving environmental benefits from trading surplus allowances (AAUs) under the Kyoto Protocol. The Green Investment Scheme (GIS), a mechanism in the framework of International Emissions Trading (IET), is designed to achieve greater flexibility in reaching the targets of the Kyoto Protocol while preserving environmental integrity of IET. However, using the GIS is not required under the Kyoto Protocol, and there is no official definition of the term. Under the GIS a party to the protocol expecting that the development of its economy will not exhaust its Kyoto quota, can sell the excess of its Kyoto quota units (AAUs) to another party. The proceeds from the AAU sales should be "greened", i.e. channelled to the development and implementation of the projects either acquiring the greenhouse gases emission reductions (hard greening) or building up the necessary framework for this process (soft greening).


= Trade in AAUs

= Latvia was one of the front-runners of GISs. World Bank (2011) reported that Latvia has stopped offering AAU sales because of low AAU prices. In 2010, Estonia was the preferred source for AAU buyers, followed by the Czech Republic and Poland. Japan's national policy to meet their Kyoto target includes the purchase of AAUs sold under GISs. In 2010, Japan and Japanese firms were the main buyers of AAUs. In terms of the international carbon market, trade in AAUs are a small proportion of overall market value. In 2010, 97% of trade in the international carbon market was driven by the

In November 2008, only 22 JI projects had been officially approved and registered. The total projected emission savings from JI by 2012 are about one tenth that of the CDM. Russia accounts for about two-thirds of these savings, with the remainder divided up roughly equally between Ukraine and the EU's New Member States. Emission savings include cuts in methane, HFC, and N2O emissions.

s, or CFCs, which are dealt with under the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer. Under the Protocol, only the Annex I Parties have committed themselves to national or joint reduction targets (formally called "quantified emission limitation and reduction objectives" (QELRO) – Article 4.1). Parties to the Kyoto Protocol not listed in Annex I of the convention (the non-Annex I Parties) are mostly low-income developing countries, and may participate in the Kyoto Protocol through the Clean Development Mechanism (explained below). The emissions limitations of Annex I Parties varies between different Parties. Some Parties have emissions limitations reduce below the base year level, some have limitations at the base year level (no permitted increase above the base year level), while others have limitations above the base year level. Emission limits do not include emissions by international aviation and shipping. Although Belarus and Turkey are listed in the convention's Annex I, they do not have emissions targets as they were not Annex I Parties when the Protocol was adopted. Kazakhstan does not have a target, but has declared that it wishes to become an Annex I Party to the convention. For most state parties, 1990 is the base year for the national GHG inventory and the calculation of the assigned amount. However, five state parties have an alternative base year: * Bulgaria: 1988; * Hungary: the average of the years 1985–1987; * Poland: 1988; * Romania: 1989; * Slovenia: 1986. Annex I Parties can use a range of sophisticated "flexibility" mechanisms (see below) to meet their targets. Annex I Parties can achieve their targets by allocating reduced annual allowances to major operators within their borders, or by allowing these operators to exceed their allocations by offsetting any excess through a mechanism that is agreed by all the parties to the UNFCCC, such as by buying emission allowances from other operators which have excess emissions credits.


Negotiations

Article 4.2 of the UNFCCC commits industrialized countries to " akethe lead" in reducing emissions. The initial aim was for industrialized countries to stabilize their emissions at 1990 levels by 2000. The failure of key industrialized countries to move in this direction was a principal reason why Kyoto moved to binding commitments. At the first UNFCCC Conference of the Parties in Berlin, the G77 was able to push for a mandate (the "Berlin mandate") where it was recognized that: * developed nations had contributed most to the then-current concentrations of GHGs in the atmosphere (see
Greenhouse gas emissions Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide (), from burning fossil fuels such as coal, petroleum, oil, and natural gas, is the main cause of climate chan ...
). * developing country emissions per-capita (i.e., average emissions per head of population) were still relatively low. * and that the share of global emissions from developing countries would grow to meet their development needs. During negotiations, the G-77 represented 133 developing countries. China was not a member of the group but an associate. It has since become a member. The Berlin mandate was recognized in the Kyoto Protocol in that developing countries were not subject to emission reduction commitments in the first Kyoto commitment period. However, the large potential for growth in developing country emissions made negotiations on this issue tense. In the final agreement, the Clean Development Mechanism was designed to limit emissions in developing countries, but in such a way that developing countries do not bear the costs for limiting emissions. The general assumption was that developing countries would face quantitative commitments in later commitment periods, and at the same time, developed countries would meet their first round commitments.


Emissions cuts

There were multiple emissions cuts proposed by UNFCCC parties during negotiations. The G77 and China were in favour of strong uniform emission cuts across the developed world. The US originally proposed for the second round of negotiations on Kyoto commitments to follow the negotiations of the first. In the end, negotiations on the second period were set to open no later than 2005. Countries over-achieving in their first period commitments can "bank" their unused allowances for use in the subsequent period. The EU initially argued for only three GHGs to be included – , , and – with other gases such as HFCs regulated separately. The EU also wanted to have a "bubble" commitment, whereby it could make a collective commitment that allowed some EU members to increase their emissions, while others cut theirs. The most vulnerable nations – the

Relation to temperature targets

At the 16th Conference of the Parties held in 2010, Parties to the UNFCCC agreed that future global warming should be limited below 2°C relative to the pre-industrial temperature level. One of the stabilization levels discussed in relation to this temperature target is to hold atmospheric concentrations of GHGs at 450

(ppm) - eq. Stabilization at 450 ppm could be associated with a 26 to 78% risk of exceeding the 2 °C target. Scenarios assessed by Gupta ''et al.'' (2007) , in suggest that Annex I emissions would need to be 25% to 40% below 1990 levels by 2020, and 80% to 95% below 1990 levels by 2050. The only Annex I Parties to have made voluntary pledges in line with this are Japan (25% below 1990 levels by 2020) and Norway (30–40% below 1990 levels by 2020). Gupta ''et al.'' (2007) also looked at what 450 ppm scenarios projected for non-Annex I Parties. Projections indicated that by 2020, non-Annex I emissions in several regions (

Projections indicated that by 2050, emissions in all non-Annex I regions would need to be substantially reduced below "business-as-usual".


Financial commitments

The Protocol also reaffirms the principle that developed countries have to pay billions of dollars, and supply technology to other countries for climate-related studies and projects. The principle was originally agreed in
UNFCCC The United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change. It is an international treaty among countries to combat "dangerous human interference with th ...

Mechanism of compliance

The protocol defines a mechanism of "compliance" as a "monitoring compliance with the commitments and penalties for
non-compliance In general, compliance means conforming to a rule, such as a specification, policy, standard or law. Compliance has traditionally been explained by reference to deterrence theory, according to which punishing a behavior will decrease the viol ...
." According to Grubb (2003), the explicit consequences of non-compliance of the treaty are weak compared to domestic law. Yet, the compliance section of the treaty was highly contested in the Marrakesh Accords.


Monitoring emissions

Monitoring emissions in international agreements is tough as in international law, there is no police power, creating the incentive for states to find 'ways around' monitoring. The Kyoto Protocol regulated six sinks and sources of Gases. Carbon dioxide, Methane, Nirous oxide, Hydroflurocarbons, Sulfur hexafluouride and Perfluorocarbons. Monitoring these gases can become quite a challenge. Methane can be monitored and measured from irrigated rice fields and can be measured by the seedling growing up to harvest. Future implications state that this can be affected by more cost effective ways to control emissions as changes in types of fertilizer can reduce emissions by 50%. In addition to this, many countries are unable to monitor certain ways of carbon absorption through trees and soils to an accurate level.


Enforcing emission cuts

If the enforcement branch determines that an Annex I country is not in compliance with its emissions limitation, then that country is required to make up the difference during the second commitment period plus an additional 30%. In addition, that country will be suspended from making transfers under an emissions trading program.

Article 25 of the Protocol specifies that the Protocol enters into force "on the ninetieth day after the date on which not less than 55 Parties to the Convention, incorporating Parties included in Annex I which accounted in total for at least 55% of the total carbon dioxide emissions for 1990 of the Annex I countries, have deposited their instruments of ratification, acceptance, approval or accession." The EU and its Member States ratified the Protocol in May 2002. Of the two conditions, the "55 parties" clause was reached on 23 May 2002 when

As of May 2013, 191 countries and one regional economic organization (the EC) have ratified the agreement, representing over 61.6% of the 1990 emissions from Annex I countries. One of the 191 ratifying states—Canada—has renounced the protocol.


Non-ratification by the US

The US signed the Protocol on 12 November 1998, during the Clinton presidency. To become binding in the US, however, the treaty had to be ratified by the

wrote a letter to President George W. Bush seeking to identify his position on the Kyoto Protocol and climate change policy. In a letter dated March 13, 2001, President Bush responded that his "Administration takes the issue of global climate change very seriously", but that "I oppose the Kyoto Protocol because it exempts 80 percent of the world, including major population centers such as China and India, from compliance, and would cause serious harm to the U.S. economy. The Senate's vote, 95-0, shows that there is a clear consensus that the Kyoto Protocol is an unfair and ineffective means of addressing global climate change concerns." The administration also questioned the scientific certainty around climate change and cited potential harms of emissions reduction to the US economy. The Tyndall Centre for Climate Change Research reported in 2001:
This policy reversal received a massive wave of criticism that was quickly picked up by the international media. Environmental groups blasted the White House, while Europeans and Japanese alike expressed deep concern and regret. ... Almost all world leaders (e.g. China, Japan, South Africa, Pacific Islands, etc.) expressed their disappointment at Bush's decision.
In response to this criticism, Bush stated: "I was responding to reality, and reality is the nation has got a real problem when it comes to energy". The Tyndall Centre called this "an overstatement used to cover up the big benefactors of this policy reversal, i.e., the US oil and coal industry, which has a powerful lobby with the administration and conservative Republican congressmen." As of 2023, the US is the only signatory that has not ratified the Protocol. The US accounted for 36.1% of emissions in 1990. As such, for the treaty to go into legal effect without US ratification, it would require a coalition including the EU, Russia, Japan, and small parties. A deal, without the US Administration, was reached in the Bonn climate talks (COP-6.5), held in 2001.


Withdrawal of Canada

In 2011, Canada, Japan and Russia stated that they would not take on further Kyoto targets. The Canadian government announced its withdrawal—possible at any time three years after ratification—from the Kyoto Protocol on 12 December 2011, effective 15 December 2012. Canada was committed to cutting its greenhouse emissions to 6% below 1990 levels by 2012, but in 2009 emissions were 17% higher than in 1990. The Harper government prioritized

Country types and their emissions


Annex I countries

Total aggregate GHG emissions excluding emissions/removals from land use, land use change and forestry (LULUCF, i.e., carbon storage in forests and soils) for all Annex I Parties (see list below) including the United States taken together decreased from 19.0 to 17.8 thousand teragrams (Tg, which is equal to 109 kg) equivalent, a decline of 6.0% during the 1990–2008 period. Several factors have contributed to this decline. The first is due to the economic restructuring in the Annex I Economies in Transition (the EITs – see Intergovernmental Emissions Trading for the list of EITs). Over the period 1990–1999, emissions fell by 40% in the EITs following the collapse of

countries. PBL publication number 500253004. JRC Technical Note number JRC65918. This led to a massive contraction of their heavy industry-based economies, with associated reductions in their fossil fuel consumption and emissions. Emissions growth in Annex I Parties have also been limited due to policies and measures (PaMs). In particular, PaMs were strengthened after 2000, helping to enhance energy efficiency and develop renewable energy sources. Energy use also decreased during the economic crisis in 2007–2008.


Annex I parties with targets

Collectively the group of industrialized countries committed to a Kyoto target, i.e., the Annex I countries excluding the US, had a target of reducing their GHG emissions by 4.2% on average for the period 2008–2012 relative to the base year, which in most cases is 1990. As noted in the preceding section, between 1990 and 1999, there was a large reduction in the emissions of the EITs. The reduction in the EITs is largely responsible for the total (aggregate) reduction (excluding LULUCF) in emissions of the Annex I countries, excluding the US. Emissions of the Annex II countries (Annex I minus the EIT countries) have experienced a limited increase in emissions from 1990 to 2006, followed by stabilization and a more marked decrease from 2007 onwards. The emissions reductions in the early nineties by the 12 EIT countries who have since joined the EU, assist the present EU-27 in meeting its collective Kyoto target.

Annex I parties without Kyoto targets

Belarus, Malta, and Turkey are Annex I Parties but did not have first-round Kyoto targets. The US had a Kyoto target of a 7% reduction relative to the 1990 level, but has not ratified the treaty. If the US had ratified the Kyoto Protocol, the average percentage reduction in total GHG emissions for the Annex I group would have been a 5.2% reduction relative to the base year.

Problem areas


Views and criticism of the Protocol

Gupta ''et al.'' (2007) assessed the literature on climate change policy. They found that no authoritative assessments of the UNFCCC or its Protocol asserted that these agreements had, or will, succeed in solving the climate problem. In these assessments, it was assumed that the UNFCCC or its Protocol would not be changed. The Framework Convention and its Protocol include provisions for future policy actions to be taken. Gupta ''et al.'' (2007) , in described the Kyoto first-round commitments as "modest", stating that they acted as a constraint on the treaty's effectiveness. It was suggested that subsequent Kyoto commitments could be made more effective with measures aimed at achieving deeper cuts in emissions, as well as having policies applied to a larger share of global emissions. In 2008, countries with a Kyoto cap made up less than one-third of annual global carbon dioxide emissions from fuel

. World Bank (2010), in commented on how the Kyoto Protocol had only had a slight effect on curbing global emissions growth. The treaty was negotiated in 1997, but in 2006, energy-related carbon dioxide emissions had grown by 24%. World Bank (2010) also stated that the treaty had provided only limited financial support to developing countries to assist them in reducing their emissions and adapting to climate change. Some environmentalists have supported the Kyoto Protocol because it is "the only game in town", and possibly because they expect that future emission reduction commitments may demand more stringent emission reductions (Aldy ''et al.''., 2003, p. 9). In 2001, seventeen national science academies stated that ratification of the Protocol represented a "small but essential first step towards stabilising atmospheric concentrations of greenhouse gases." Some environmentalists and scientists have criticized the existing commitments for being too weak (Grubb, 2000, p. 5). The United States (under former President

Compliance

38 developed countries committed to limiting their greenhouse gas emissions. Because the United States did not ratify and Canada withdrew, the emission limits remained in force for 36 countries. All of them complied with the Protocol. However, nine countries (Austria, Denmark, Iceland, Japan, Lichtenstein, Luxembourg, Norway, Spain and Switzerland) had to resort to the flexibility mechanisms because their national emissions were slightly greater than their targets. In total, the 36 countries that fully participated in the Protocol were committed to reducing their aggregate emissions by 4% from the 1990 base year. Their average annual emissions in 2008–2012 were 24.2% below the 1990 level. Hence, they surpassed their aggregate commitment by a large margin.

significantly reduced emissions during the first Kyoto commitment period. The 36 countries that were committed to emission reductions only accounted for 24% of the global greenhouse gas emissions in 2010. Even though these countries significantly reduced their emissions during the Kyoto commitment period, other countries increased their emissions so much that the global emissions increased by 32% from 1990 to 2010.


Emission trends in developing countries

In several large developing countries and fast growing economies (China, India, Thailand, Indonesia, Egypt, and Iran) GHG emissions have increased rapidly (PBL, 2009). For example, emissions in China have risen strongly over the 1990–2005 period, often by more than 10% year. Emissions per-capita in non-Annex I countries are still, for the most part, much lower than in industrialized countries. Non-Annex I countries do not have quantitative emission reduction commitments, but they are committed to mitigation actions. China, for example, has had a national policy programme to reduce emissions growth, which included the closure of old, less efficient coal-fired power plants.


Views on the flexibility mechanisms

(CDM). Toth ''et al.'' summarize the arguments for and against flexibility: , in The flexibility mechanisms have attracted both positive and negative comments. One of the arguments made in favour of the flexibility mechanisms is that they can reduce the costs incurred by Annex I Parties in meeting their Kyoto commitments. Criticisms of flexibility have, for example, included the ineffectiveness of emissions trading in promoting investment in non-fossil energy sources, and adverse impacts of CDM projects on local communities in developing countries. China, India, Indonesia and Brazil were not required to reduce their CO2 emissions. The remaining signatory countries were not obliged to implement a common framework nor specific measures, but to reach an emission reduction target for which they can benefit of a

for carbon credits multilaterally exchanged from each other. The Emissions-trading Scheme (ETS) allowed countries to host polluting industries and to buy from other countries the property of their environmental merits and virtuous patterns. A 2021 review considers both the institutional design and the political strategies that have affected the adoption of the Kyoto protocol. It concludes that the Kyoto protocol's relatively small impact on global carbon dioxide emissions reflects a number of factors, including "deliberate political strategy, unequal power, and the absence of leadership" among and within nations.

Amendment and successor

In the non-binding " Washington Declaration" agreed on 16 February 2007, heads of governments from Canada, France, Germany, Italy, Japan, Russia, the United Kingdom, the United States, Brazil, China, India, Mexico and South Africa agreed in principle on the outline of a successor to the Kyoto Protocol. They envisaged a global cap-and-trade system that would apply to both industrialized nations and

, and initially hoped that it would be in place by 2009. The United Nations Climate Change Conference in Copenhagen in December 2009 was one of the annual series of UN meetings that followed the 1992 Earth Summit in Rio. In 1997 the talks led to the Kyoto Protocol, and the conference in Copenhagen was considered to be the opportunity to agree a successor to Kyoto that would bring about meaningful carbon cuts. The 2010 Cancún agreements include voluntary pledges made by 76 developed and developing countries to control their emissions of greenhouse gases. In 2010, these 76 countries were collectively responsible for 85% of annual global emissions. Executive summary i

By May 2012, the US, Japan, Russia, and Canada had indicated they would not sign up to a second Kyoto commitment period. In November 2012, Australia confirmed it would participate in a second commitment period under the Kyoto Protocol and New Zealand confirmed that it would not. New Zealand's climate minister Tim Groser said the 15-year-old Kyoto Protocol was outdated, and that New Zealand was "ahead of the curve" in looking for a replacement that would include developing nations.

, an agreement was reached to extend the Protocol to 2020 and to set a date of 2015 for the development of a successor document, to be implemented from 2020 (see lede for more information). The outcome of the Doha talks has received a mixed response, with small island states critical of the overall package. The Kyoto second commitment period applies to about 11% of annual global emissions of greenhouse gases. Other results of the conference include a timetable for a global agreement to be adopted by 2015 which includes all countries. , p.2.
