The Kyoto Protocol (Japanese: 京都議定書, Hepburn: Kyōto Giteisho) 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 global warming is occurring and 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 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.
The Climate Change Act 2008 is an Act of the Parliament of the United Kingdom. The Act makes it the duty of the Secretary of State to ensure that the net UK carbon account for all six Kyoto greenhouse gases for the year 2050 is at least 100% lower than the 1990 baseline, toward avoiding dangerous climate change. The Act aims to enable the United Kingdom to become a low-carbon economy and gives ministers powers to introduce the measures necessary to achieve a range of greenhouse gas reduction targets. An independent Committee on Climate Change was created under the Act to provide advice to UK Government on these targets and related policies. In the act Secretary of State refers to the Secretary of State for Energy and Climate Change.
The Climate Change Committee (CCC), originally named the Committee on Climate Change, is an independent non-departmental public body, formed under the Climate Change Act (2008) to advise the United Kingdom and devolved Governments and Parliaments on tackling and preparing for climate change. The Committee provides advice on setting carbon budgets, and reports regularly to the Parliaments and Assemblies on the progress made in reducing greenhouse gas emissions. Notably, in 2019 the CCC recommended the adoption of a target of net zero greenhouse gas emissions by the United Kingdom by 2050. On 27 June 2019 the British Parliament amended the Climate Change Act (2008) to include a commitment to net zero emissions by 2050. The CCC also advises and comments on the UK's progress on climate change adaptation through updates to Parliament.
The Carbon Pollution Reduction Scheme was a cap-and-trade emissions trading scheme for anthropogenic greenhouse gases proposed by the Rudd government, as part of its climate change policy, which had been due to commence in Australia in 2010. It marked a major change in the energy policy of Australia. The policy began to be formulated in April 2007, when the federal Labor Party was in Opposition and the six Labor-controlled states commissioned an independent review on energy policy, the Garnaut Climate Change Review, which published a number of reports. After Labor won the 2007 federal election and formed government, it published a Green Paper on climate change for discussion and comment. The Federal Treasury then modelled some of the financial and economic impacts of the proposed CPRS scheme.
The environmental policy of the Stephen Harper government was implemented when Stephen Harper was the Prime Minister of Canada from 2006 to 2015, under two minority governments until 2011 when the Conservative Party of Canada won a majority in the 2011 Canadian federal election. During the term of Stephen Harper, Canada's greenhouse gas emissions decreased from 730 to 723 Mt of carbon dioxide equivalent. In contrast, during the period from 1993 until 2006, under various Liberal governments, Canada's greenhouse gas emissions increased 617 to 730 Mt of carbon dioxide equivalent.
Carbon emission trading (also called emission trading scheme (ETS) or cap and trade) is a type of emission trading scheme designed for carbon dioxide (CO2) and other greenhouse gases (GHG). It is a form of carbon pricing. Its purpose is to limit climate change by creating a market with limited allowances for emissions. This can lower competitiveness of fossil fuels and accelerate investments into low carbon sources of energy such as wind power and photovoltaics. Fossil fuels are the main driver for climate change. They account for 89% of all CO2 emissions and 68% of all GHG emissions.
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.
Climate change in New Zealand involves historical, current and future changes in the climate of New Zealand; and New Zealand's contribution and response to global climate change. Summers are becoming longer and hotter, and some glaciers have melted completely and others have shrunk. In 2021, the Ministry for the Environment estimated that New Zealand's gross emissions were 0.17% of the world's total gross greenhouse gas emissions. However, on a per capita basis, New Zealand is a significant emitter, the sixth highest within the Annex I countries, whereas on absolute gross emissions New Zealand is ranked as the 24th highest emitter.
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 Climate Change Accountability Act is a Private Member's Bill that was submitted in the 39th, 40th and 41st Canadian Parliaments. It was originally tabled in October 2006 in the House of Commons of Canada as Bill C-377 of the 39th Parliament by Jack Layton, then the leader of the New Democratic Party of Canada (NDP). It passed third reading by a vote of 148 to 116 with the support of caucuses of the Liberal Party of Canada, the Bloc Québécois and the NDP. However, Bill C-377 died as it was still before the Senate when Parliament was dissolved for the 2008 Canadian federal election.
The New Zealand Emissions Trading Scheme is an all-gases partial-coverage uncapped domestic emissions trading scheme that features price floors, forestry offsetting, free allocation and auctioning of emissions units.
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 Climate Change Response Act 2002 is an Act of Parliament passed by the government of New Zealand.
The Kyoto Protocol was an international treaty which extended the 1992 United Nations Framework Convention on Climate Change. A number of governments across the world took a variety of actions.
Climate change in Scotland is causing a range of impacts on Scotland, and its mitigation and adaptation is a matter for the devolved Scottish Parliament. Climate change has already changed timings of spring events such as leaf unfolding, bird migration and egg-laying. Severe effects are likely to occur on biodiversity.
The Climate Change Response Amendment Act 2008 was a statute enacted in September 2008 by the Fifth Labour Government of New Zealand that established the first version of the New Zealand Emissions Trading Scheme, a national all-sectors all-greenhouse gases uncapped and highly internationally linked emissions trading scheme.
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.
The Clean Energy Act 2011 was an Act of the Australian Parliament, the main Act in a package of legislation that established an Australian emissions trading scheme (ETS), to be preceded by a three-year period of fixed carbon pricing in Australia designed to reduce carbon dioxide emissions as part of efforts to combat global warming.
The Climate Change Response Amendment Act 2019 is an Act of Parliament in New Zealand that amends the Climate Change Response Act 2002 to provide a framework for New Zealand to develop and implement climate change policies in support of the Paris Agreement.
