Global warming potential (GWP) is a measure of how much infrared thermal radiation a greenhouse gas added to the atmosphere would absorb over a given time frame, as a multiple of the radiation that would be absorbed by the same mass of added carbon dioxide. GWP is 1 for CO2. For other gases it depends on the how strongly the gas absorbs infrared thermal radiation, how quickly the gas leaves the atmosphere, and the time frame being considered.
The Kyoto Protocol was an international treaty which extended the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that (part one) global warming is occurring and (part two) that human-made CO2 emissions are driving it. The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and entered into force on 16 February 2005. There were 192 parties (Canada withdrew from the protocol, effective December 2012) to the Protocol in 2020.
The United Nations Framework Convention on Climate Change (UNFCCC) established an international environmental treaty to combat "dangerous human interference with the climate system", in part by stabilizing greenhouse gas concentrations in the atmosphere. It was signed by 154 states at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro from 3 to 14 June 1992. Its original secretariat was in Geneva but relocated to Bonn in 1996. It entered into force on 21 March 1994.
The Clean Development Mechanism (CDM) is a United Nations-run carbon offset scheme allowing countries to fund greenhouse gas emissions-reducing projects in other countries and claim the saved emissions as part of their own efforts to meet international emissions targets. It is one of the three Flexible Mechanisms defined in the Kyoto Protocol. The CDM, defined in Article 12 of the Protocol, was intended to meet two objectives: (1) to assist non-Annex I countries achieve sustainable development and reduce their carbon footprints; and (2) to assist Annex I countries in achieving compliance with their emissions reduction commitments.
The emission reduction unit (ERU) was an emissions unit issued under a Joint Implementation project in terms of the Kyoto Protocol. An ERU represented a reduction of greenhouse gases under the Joint Implementation mechanism, where it represented one tonne of CO2 equivalent reduced.
Flexible mechanisms, also sometimes known as Flexibility Mechanisms or Kyoto Mechanisms, refers to emissions trading, the Clean Development Mechanism and Joint Implementation. These are mechanisms defined under the Kyoto Protocol intended to lower the overall costs of achieving its emissions targets. These mechanisms enable Parties to achieve emission reductions or to remove carbon from the atmosphere cost-effectively in other countries. While the cost of limiting emissions varies considerably from region to region, the benefit for the atmosphere is in principle the same, wherever the action is taken.
Joint Implementation (JI) is one of three flexibility mechanisms set out in the Kyoto Protocol to help countries with binding greenhouse gas emissions targets meet their treaty obligations. Under Article 6, any Annex I country can invest in a project to reduce greenhouse gas emissions in any other Annex I country as an alternative to reducing emissions domestically. In this way countries can lower the costs of complying with their Kyoto targets by investing in projects where reducing emissions may be cheaper and applying the resulting Emission Reduction Units (ERUs) towards their commitment goal.
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 models. Policy makers use inventories to develop strategies and policies for emissions reductions and to track the progress of those policies.
"Supplementarity", also referred to as "the supplementary principle", is one of the main principles of the Kyoto Protocol. The concept is that internal abatement of emissions should take precedence before external participation in flexible mechanisms. These mechanisms include emissions trading, Clean Development Mechanism (CDM), and Joint Implementation (JI).
Canada was active in the negotiations that led to the Kyoto Protocol in 1997. The Liberal government that signed the accord in 1997 ratified it in parliament in 2002. Canada's Kyoto target was a 6% total reduction in greenhouse gas (GHG) emissions by 2012, compared to 1990 levels of 461 megatonnes (Mt). Despite signing the accord, greenhouse gas emissions increased approximately 24.1% between 1990 and 2008. In 2011, Conservative Prime Minister Stephen Harper withdrew Canada from the Kyoto Protocol.
The 2008 United Nations Climate Change Conference took place at PIF Congress Centre, Poznań International Fair (PIF), in Poznań, Poland, between December 1 and December 12, 2008. Representatives from over 180 countries attended along with observers from intergovernmental and nongovernmental organizations.
Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005. According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors.

Brazil has established a strong public policy using Clean Development Mechanism Projects to reduce methane emissions from landfills. An important component of these projects is the sale of avoided emissions by the private market to generate revenue.
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 the formal meeting of the UNFCCC parties 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 the Meeting of Parties to the Kyoto Protocol" (CMP); also parties to the convention that are not parties to the protocol can participate in protocol-related meetings as observers. From 2011 to 2015 the meetings were used to negotiate the Paris Agreement as part of the Durban platform, which created a general path towards climate action. Any final text of a COP must be agreed by consensus.
Coal, cars and lorries vent more than a third of Turkey's five hundred million tonnes of annual greenhouse gas emissions—mostly carbon dioxide—and are part of the cause of climate change in Turkey. The nation's coal-fired power stations emit the most carbon dioxide, and other significant sources are road vehicles running on petrol or diesel. After coal and oil the third most polluting fuel is fossil gas; which is burnt in Turkey's gas-fired power stations, homes and workplaces. Much methane is belched by livestock; cows alone produce half of the greenhouse gas from agriculture in Turkey.
The history of climate change policy and politics refers to the continuing history of political actions, policies, trends, controversies and activist efforts as they pertain to the issue of global warming and other environmental anomalies. Dryzek, Norgaard, and Schlosberg suggest that critical reflection on the history of climate policy is necessary because it provides 'ways to think about one of the most difficult issues we human beings have brought upon ourselves in our short life on the planet’.
