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 Regional Greenhouse Gas Initiative (RGGI, pronounced "Reggie") is the first mandatory market-based program to reduce greenhouse gas emissions by the United States. RGGI is a cooperative effort among the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Pennsylvania, Vermont and Virginia to cap and reduce carbon dioxide (CO2) emissions from the power sector. RGGI compliance obligations apply to fossil-fueled power plants 25 megawatts (MW) and larger within the 12-state region. North Carolina is currently considering joining RGGI.
Business action on climate change includes a range of activities relating to climate change, and to influencing political decisions on climate change-related regulation, such as the Kyoto Protocol. Major multinationals have played and to some extent continue to play a significant role in the politics of climate change, especially in the United States, through lobbying of government and funding of climate change deniers. Business also plays a key role in the mitigation of climate change, through decisions to invest in researching and implementing new energy technologies and energy efficiency measures.
The Global Warming Solutions Act of 2006, or Assembly Bill (AB) 32, is a California State Law that fights global warming by establishing a comprehensive program to reduce greenhouse gas emissions from all sources throughout the state. AB32 was co-authored by then-Assemblymember Fran Pavley and then-Speaker of the California Assembly Fabian Nunez and signed into law by Governor Arnold Schwarzenegger on September 27, 2006.
Western Climate Initiative, Inc. (WCI) is a 501(c)(3) non-profit corporation which administers the shared emissions trading market between the American state of California and the Canadian province of Quebec as well as separately administering the individual emissions trading systems in the Canadian province of Nova Scotia and American state of Washington. It also provides administrative, technical and infrastructure services to support the implementation of cap-and-trade programs in other North American jurisdictions. The organization was originally founded in February 2007 by the governors of five western states with the goal of developing a multi-sector, market-based program to reduce greenhouse gas emissions; it was incorporated in its current form in 2011.
The Climate Registry (TCR) is a non-profit organization governed by U.S. states and Canadian provinces and territories. TCR designs and operates voluntary and compliance greenhouse gas (GHG) reporting programs globally, and assists organizations in measuring, reporting and verifying the carbon in their operations in order to manage and reduce it. TCR also consults with governments nationally and internationally on all aspects of GHG measurement, reporting, and verification.
The United States produced 5.2 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2020, the second largest in the world after greenhouse gas emissions by China and among the countries with the highest greenhouse gas emissions per person. In 2019 China is estimated to have emitted 27% of world GHG, followed by the United States with 11%, then India with 6.6%. In total the United States has emitted a quarter of world GHG, more than any other country. Annual emissions are over 15 tons per person and, amongst the top eight emitters, is the highest country by greenhouse gas emissions per person. However, the IEA estimates that the richest decile in the US emits over 55 tonnes of CO2 per capita each year. Because coal-fired power stations are gradually shutting down, in the 2010s emissions from electricity generation fell to second place behind transportation which is now the largest single source. In 2020, 27% of the GHG emissions of the United States were from transportation, 25% from electricity, 24% from industry, 13% from commercial and residential buildings and 11% from agriculture. In 2021, the electric power sector was the second largest source of U.S. greenhouse gas emissions, accounting for 25% of the U.S. total. These greenhouse gas emissions are contributing to climate change in the United States, as well as worldwide.
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 New England Governors and Eastern Canadian Premiers (NEG-ECP) Climate Change Action Plan 2001 is a resolution adopted on August 28, 2001, by the New England Governors and the Eastern Canadian Premiers. The resolution calls for a reduction in greenhouse gas (GHG) emissions to 1990 levels by 2010, at least 10% below 1990 levels by 2020, 35-45% below 1990 levels by 2030, and a 75-85% reduction of 2001 levels by 2050.
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.
The American Clean Energy and Security Act of 2009 (ACES) was an energy bill in the 111th United States Congress that would have established a variant of an emissions trading plan similar to the European Union Emission Trading Scheme. The bill was approved by the House of Representatives on June 26, 2009, by a vote of 219–212. With no prospect of overcoming a threatened Republican filibuster, the bill was never brought to the floor of the Senate for discussion or a vote. The House passage of the bill was the "first time either house of Congress had approved a bill meant to curb the heat-trapping gases scientists have linked to climate change."
The Asia-Pacific Emissions Trading Forum (AETF) was an information service and business network dealing with domestic and international developments in emissions trading policy in Australia and the Asia-Pacific region. The AETF was originally called the Australasian Emissions Trading Forum, and was founded in 1998 under the auspices of the Sydney Futures Exchange following a proposal from Beck Consulting Services. From 2001 until 2011 the AETF published the AETF Review, held regular member meetings and convened numerous events and conferences. The AETF Review was published six times per year and included original articles on emissions trading developments and related topics.
Climate change in Canada has had large impacts on the country's environment and landscapes. These events are likely to become even more frequent and severe in the future due to the continued release of greenhouse gases into the atmosphere. The number of climate change–related events, such as the 2021 British Columbia Floods and an increasing number of forest fires, has become an increasing concern over time. Canada's annual average temperature over land has warmed by 1.7 degrees Celsius since 1948. The rate of warming is even higher in Canada's north, the Prairies, and northern British Columbia. The country's precipitation has increased in recent years and extreme weather events have become more common.
The climate change policy of the United States has major impacts on global climate change and global climate change mitigation. This is because the United States is the second largest emitter of greenhouse gasses in the world after China, and is among the countries with the highest greenhouse gas emissions per person in the world. In total, the United States has emitted over 400 billion metric tons of greenhouse gasses, more than any country in the world.
The Copenhagen Accord is a document which delegates at the 15th session of the Conference of Parties to the United Nations Framework Convention on Climate Change agreed to "take note of" at the final plenary on 18 December 2009.
The Sustainable Communities and Climate Protection Act of 2008, also known as Senate Bill 375 or SB 375, is a State of California law targeting greenhouse gas emissions from passenger vehicles. The Global Warming Solutions Act of 2006 sets goals for the reduction of statewide greenhouse gas emissions. Passenger vehicles are the single largest source of greenhouse gas emissions statewide, accounting for 30% of total emissions. SB 375 therefore provides key support to achieve the goals of AB 32.
Air pollution in Germany has significantly decreased over the past decade. Air pollution occurs when harmful substances are released into the Earth's atmosphere. These pollutants are released through human activity and natural sources. Germany took interest in reducing its greenhouse gas (GHG) emissions by switching to renewable energy sources. Renewable energy use rate from 6.3% in 2000 to 34% in 2016. Through the transition to renewable energy sources, some people believe Germany has become the climate change policy leader and renewable energy leader in the European Union (EU) and in the world with ambitious climate change programs, though Germany's CO
2 emissions per capita are in fact among the highest in Europe, almost twice those of e.g. France. The current goal of the German government was approved on 14 November 2016 in the German Climate Action Plan 2050, which outlines measures by which Germany can meet its greenhouse gas emissions by 2050. By 2050, Germany wants to reduce their GHGs by 80 to 95% and by 2030 they want to reduce it by 55%, compared to the EU target of 40%.
As the most populous state in the United States, California's climate policies influence both global climate change and federal climate policy. In line with the views of climate scientists, the state of California has progressively passed emission-reduction legislation.
Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning in China, including coal-fired power stations, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for 13 gigatonnes (Gt) or 25% of global emissions.
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'.
