America's Pledge is a coalition of cities, states, universities, businesses, public sector leaders and citizens that want to ensure that United States fulfill its commitments in Paris Agreement and remains a global leader in the fight against climate change. The organization was created and is led by Michael Bloomberg and Jerry Brown. It was created in 2017 when Donald Trump decided to pull out from the Paris Agreement. The coalition is collecting and spreading information about climate action in the United States and create further action by providing to cities, businesses, states, in USA and possibly abroad, the necessary information for organizing it.

According to the coalition's 2019 report, the number of Americans who support the aim of the initiative is growing. The report states that multiple coalitions committed to support of the Paris Agreement represent 65% of the U.S. population, 51% of U.S. greenhouse gas emissions, and 68% of the U.S. GDP. Already existing policy by these coalitions could reduce emissions by 19% by 2025 and by 25% by 2030, from the level in the year 2005, according to the report which also claims that additional local action without governmental support could reduce greenhouse gas emission of USA by 37% by 2030 from the level in 2005. With federal support, the report claims, the emissions could be reduced by 49% by 2030 and achieve a decline consistent with the 1.5 degree target of the UN. The coalitions formed for the purpose include We Are Still In, US Climate Alliance, Climate Mayors and more [3] [4]
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 the climate system". The main way to do this is limiting the increase in greenhouse gases in the atmosphere. It was signed in 1992 by 154 states at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro. The treaty entered into force on 21 March 1994. "UNFCCC" is also the name of the Secretariat charged with supporting the operation of the convention, with offices on the UN Campus in Bonn, Germany.
Climate Group is a nonprofit organisation with a mission to drive climate action, fast, and achieve a world of net zero carbon emissions by 2050, with greater prosperity for all. The organisation builds influential networks of business and governments to unlock the power of collective action and scale. With its partners, Climate Group drives demand for net zero solutions, moving whole systems such as energy, transport, the built environment, industry and food towards a cleaner future. The organisation and its members are helping to shift global markets and policies towards faster reductions in carbon emissions.
Business action on climate change is a topic which since 2000 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 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.
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. Cumulatively, the United States has emitted over a trillion metric tons of greenhouse gases, 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 Paris Agreement is an international treaty on climate change that was signed in 2016. The treaty covers climate change mitigation, adaptation, and finance. The Paris Agreement was negotiated by 196 parties at the 2015 United Nations Climate Change Conference near Paris, France. As of February 2023, 195 members of the United Nations Framework Convention on Climate Change (UNFCCC) are parties to the agreement. Of the three UNFCCC member states which have not ratified the agreement, the only major emitter is Iran. The United States withdrew from the agreement in 2020, but rejoined in 2021.
Climate change has resulted in an increase in temperature of 2.3 °C (4.14 °F) (2022) in Europe compared to pre-industrial levels. Europe is the fastest warming continent in the world. Europe's climate is getting warmer due to anthropogenic activity. According to international climate experts, global temperature rise should not exceed 2 °C to prevent the most dangerous consequences of climate change; without reduction in greenhouse gas emissions, this could happen before 2050. Climate change has implications for all regions of Europe, with the extent and nature of impacts varying across the continent.
The nationally determined contributions (NDCs) are commitments that countries make to reduce their greenhouse gas emissions as part of climate change mitigation. These commitments include the necessary policies and measures for achieving the global targets set out in the Paris Agreement. The Paris Agreement has a long-term temperature goal which is to keep the rise in global surface temperature to well below 2 °C (3.6 °F) above pre-industrial levels. The treaty also states that preferably the limit of the increase should only be 1.5 °C (2.7 °F). To achieve this temperature goal, greenhouse gas emissions should be reduced as soon as, and by as much as, possible. To stay below 1.5 °C of global warming, emissions need to be cut by roughly 50% by 2030. This figure takes into account each country's documented pledges or NDCs.
The Clean Power Plan was an Obama administration policy aimed at combating climate change that was first proposed by the Environmental Protection Agency (EPA) in June 2014. The final version of the plan was unveiled by President Barack Obama on August 3, 2015. Each state was assigned an individual goal for reducing carbon emissions, which could be accomplished how they saw fit, but with the possibility of the EPA stepping in if the state refused to submit a plan. If every state met its target, the plan was projected to reduce carbon emissions from electricity generation 32% by 2030, relative to 2005 levels, as well as achieving various health benefits due to reduced air pollution.
Climate change is leading to long-term impacts on agriculture in Germany, more intense heatwaves and coldwaves, flash and coastal flooding, and reduced water availability. Debates over how to address these long-term challenges caused by climate change have also sparked changes in the energy sector and in mitigation strategies. Germany's energiewende has been a significant political issue in German politics that has made coalition talks difficult for Angela Merkel's CDU.
The Under2 Coalition is a coalition of subnational governments that aims to achieve greenhouse gases emissions mitigation. It started as a memorandum of understanding, which was signed by twelve founding jurisdictions on May 19, 2015 in Sacramento, California. Although it was originally called the Under2 MOU, it became known as the Under2 Coalition in 2017. As of June 2024, the coalition represents 178 individual states, regions, provinces and subnational governments along with several other national and subnational entities. The list of signatories has grown to 270 governments, representing over 1.75 billion people and 50% of the world economy. The Under2 MOU was conceived through a partnership between the governments of California and Baden-Wurttemberg, with Climate Group acting as secretariat.
The 2017 United Nations Climate Change Conference (COP23) was an international meeting of political leaders, non-state actors and activists to discuss environmental issues. It was held at UN Campus in Bonn, Germany, during 6–17 November 2017. The conference incorporated the 23rd Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), the thirteenth meeting of the parties for the Kyoto Protocol (CMP13), and the second session of the first meeting of the parties for the Paris Agreement.
The 2021 United Nations Climate Change Conference, more commonly referred to as COP26, was the 26th United Nations Climate Change conference, held at the SEC Centre in Glasgow, Scotland, United Kingdom, from 31 October to 13 November 2021. The president of the conference was UK cabinet minister Alok Sharma. Delayed for a year due to the COVID-19 pandemic, it was the 26th Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC), the third meeting of the parties to the 2015 Paris Agreement, and the 16th meeting of the parties to the Kyoto Protocol (CMP16).
The 2019 UN Climate Action Summit was held at the headquarters of the United Nations in New York City on 23 September 2019. The UN 2019 Climate Summit convened on the theme, "Climate Action Summit 2019: A Race We Can Win. A Race We Must Win." The goal of the summit was to further climate action to reduce greenhouse gas emissions to prevent the mean global temperature from rising by more than 1.5 °C (2.7 °F) above preindustrial levels. Sixty countries were expected to "announce steps to reduce emissions and support populations most vulnerable to the climate crisis" including France, a number of other European countries, small island countries and India. To increase pressure on political and economic actors to achieve the aims of the summit, a global climate strike was held around the world on 20 September with over four million participants.
India was ranked seventh among the list of countries most affected by climate change in 2019. India emits about 3 gigatonnes (Gt) CO2eq of greenhouse gases each year; about two and a half tons per person, which is less than the world average. The country emits 7% of global emissions, despite having 17% of the world population. The climate change performance index of India ranks eighth among 63 countries which account for 92% of all GHG emissions in the year 2021.
Sustainable Development Goal 13 is to limit and adapt to climate change. It is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. The official mission statement of this goal is to "Take urgent action to combat climate change and its impacts". SDG 13 and SDG 7 on clean energy are closely related and complementary.
The environmental policy of the Joe Biden administration includes a series of laws, regulations, and programs introduced by United States President Joe Biden since he took office in January 2021. Many of the actions taken by the Biden administration reversed the policies of his predecessor, Donald Trump. Biden's climate change policy focuses on reducing greenhouse gas emissions, similar to the efforts taken by the Obama administration. Biden promised to end and reverse deforestation and land degradation by 2030. The main climate target of the Biden administration is to reduce greenhouse gas emissions by the United States to net zero by 2050. A climate team was created to lead the effort.
The 2021 Leaders' Summit on Climate was a virtual climate summit on April 22–23, 2021, organized by the Joe Biden administration, with leaders from various countries. At the summit Biden announced that greenhouse gas emissions by the United States would be reduced by 50% - 52% relative to the level of 2005 by 2030. Overall, the commitments made at the summit reduce the gap between governments' current pledges and the 1.5 degrees target of the Paris Agreement by 12% - 14%. If the pledges are accomplished, greenhouse gas emissions will fall by 2.6% - 3.7% more in comparison to the pledges before the summit. The results of the summit were described by Climate Action Tracker as a step forward in the fight against climate change.
Climate TRACE is an independent group which monitors and publishes greenhouse gas emissions. It launched in 2021 before COP26, and improves monitoring, reporting and verification (MRV) of both carbon dioxide and methane. The group monitors sources such as coal mines and power station smokestacks worldwide, with satellite data and artificial intelligence.
