A carbon tax is a tax levied on the carbon emissions from producing goods and services. Carbon taxes are intended to make visible the hidden social costs of carbon emissions. They are designed to reduce greenhouse gas emissions by essentially increasing the price of fossil fuels. This both decreases demand for goods and services that produce high emissions and incentivizes making them less carbon-intensive. When a fossil fuel such as coal, petroleum, or natural gas is burned, most or all of its carbon is converted to CO2. Greenhouse gas emissions cause climate change. This negative externality can be reduced by taxing carbon content at any point in the product cycle.
The politics of climate change results from different perspectives on how to respond to climate change. Global warming is driven largely by the emissions of greenhouse gases due to human economic activity, especially the burning of fossil fuels, certain industries like cement and steel production, and land use for agriculture and forestry. Since the Industrial Revolution, fossil fuels have provided the main source of energy for economic and technological development. The centrality of fossil fuels and other carbon-intensive industries has resulted in much resistance to climate friendly policy, despite widespread scientific consensus that such policy is necessary.
The energy policy of the United States is determined by federal, state, and local entities. It addresses issues of energy production, distribution, consumption, and modes of use, such as building codes, mileage standards, and commuting policies. Energy policy may be addressed via legislation, regulation, court decisions, public participation, and other techniques.
William Dawbney Nordhaus is an American economist. He was a Sterling Professor of Economics at Yale University, best known for his work in economic modeling and climate change, and a co-recipient of the 2018 Nobel Memorial Prize in Economic Sciences. Nordhaus received the prize "for integrating climate change into long-run macroeconomic analysis".

The Stern Review on the Economics of Climate Change is a 700-page report released for the Government of the United Kingdom on 30 October 2006 by economist Nicholas Stern, chair of the Grantham Research Institute on Climate Change and the Environment at the London School of Economics (LSE) and also chair of the Centre for Climate Change Economics and Policy (CCCEP) at Leeds University and LSE. The report discusses the effect of global warming on the world economy. Although not the first economic report on climate change, it is significant as the largest and most widely known and discussed report of its kind.
Richard S. J. Tol is a professor of economics at the University of Sussex. He is also professor of the economics of climate change at the Vrije Universiteit Amsterdam. He is a member of the Academia Europaea.
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.
Carbon emission trading (also called carbon market, 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 reduce the competitiveness of fossil fuels, and instead accelerate investments into renewable energy, such as wind power and solar power. Fossil fuels are the main driver for climate change. They account for 89% of all CO2 emissions and 68% of all GHG emissions.
The environmental policy of the United States is a federal governmental action to regulate activities that have an environmental impact in the United States. The goal of environmental policy is to protect the environment for future generations while interfering as little as possible with the efficiency of commerce or the liberty of the people and to limit inequity in who is burdened with environmental costs. As his first official act bringing in the 1970s, President Richard Nixon signed the U.S. National Environmental Policy Act (NEPA) into law on New Years Day, 1970. Also in the same year, America began celebrating Earth Day, which has been called "the big bang of U.S. environmental politics, launching the country on a sweeping social learning curve about ecological management never before experienced or attempted in any other nation." NEPA established a comprehensive US national environmental policy and created the requirement to prepare an environmental impact statement for “major federal actions significantly affecting the quality of the environment.” Author and consultant Charles H. Eccleston has called NEPA the world's “environmental Magna Carta”.
Climate change has led to the United States warming by 2.6 °F since 1970. The climate of the United States is shifting in ways that are widespread and varied between regions. From 2010 to 2019, the United States experienced its hottest decade on record. Extreme weather events, invasive species, floods and droughts are increasing. Climate change's impacts on tropical cyclones and sea level rise also affects regions of the country.
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 a trillion metric tons of greenhouse gasses, more than any country in the world.

The Climate Action Plan is an environmental plan by Barack Obama, the 44th President of the United States, that proposed a reduction in carbon dioxide emissions. It included preserving forests, encouraging alternate fuels, and increasing the study of climate change. The plan was first prepared in 2008 and was then updated every two years.
The Clean Power Plan was an Obama administration policy aimed at combating anthropogenic 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.
The Climate Leadership Council is a bipartisan non-profit organization that advocates for a carbon fee and dividends policy that would tax carbon emissions and refund all the money to Americans in payments of approximately $2,000 a year for a family of four. The plan would reduce emissions by 50 percent by 2035, according to an economic model by Resources for the Future.

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. John Kerry leads the effort as Special Envoy for Climate.
