A carbon tax is a tax levied on the carbon emissions required to produce goods and services. Carbon taxes are intended to make visible the "hidden" social costs of carbon emissions, which are otherwise felt only in indirect ways like more severe weather events. In this way, they are designed to reduce greenhouse gas emissions by increasing prices of the fossil fuels that emit them when burned. This both decreases demand for goods and services that produce high emissions and incentivizes making them less carbon-intensive. In its simplest form, a carbon tax covers only CO2 emissions; however, it could also cover other greenhouse gases, such as methane or nitrous oxide, by taxing such emissions based on their CO2-equivalent global warming potential. When a hydrocarbon fuel such as coal, petroleum, or natural gas is burned, most or all of its carbon is converted to CO
2. Greenhouse gas emissions cause climate change, which damages the environment and human health. This negative externality can be reduced by taxing carbon content at any point in the product cycle. Carbon taxes are thus a type of Pigovian tax.
The economic analysis of climate change explains how economic thinking, tools and techniques are applied to calculate the magnitude and distribution of damage caused by climate change. It also informs the policies and approaches for mitigation and adaptation to climate change from global to household scales. This topic is also inclusive of alternative economic approaches, including ecological economics and degrowth. In a cost–benefit analysis, the trade offs between climate change impacts, adaptation, and mitigation are made explicit. Cost–benefit analyses of climate change are produced using integrated assessment models (IAMs), which incorporate aspects of the natural, social, and economic sciences. The total economic impacts from climate change are difficult to estimate, but increase for higher temperature changes.
The United Nations Intergovernmental Panel on Climate Change (IPCC) published a special report on Renewable Energy Sources and Climate Change Mitigation (SRREN) on May 9, 2011. The report developed under the leadership of Ottmar Edenhofer evaluates the global potential for using renewable energy to mitigate climate change. This IPCC special report provides broader coverage of renewable energy than was included in the IPCC's 2007 climate change assessment report, as well as stronger renewable energy policy coverage.
The Potsdam Institute for Climate Impact Research is a German government-funded research institute addressing crucial scientific questions in the fields of global change, climate impacts, and sustainable development. Ranked among the top environmental think tanks worldwide, it is one of the leading research institutions and part of a global network of scientific and academic institutions working on questions of global environmental change. It is a member of the Leibniz Association, whose institutions perform research on subjects of high relevance to society.

He is a Professor of the Dynamics of the Climate System at Institute for Physics and Astrophysics of the Potsdam University, Germany. He has been involved in the assessment report of the Intergovernmental Panel on Climate Change since 2004. Levermann advises political and economic stakeholders on the issue of climate change.
The economics of climate change mitigation is part of the economics of climate change related to climate change mitigation, that is actions that are designed to limit the amount of long-term climate change.
Johan Rockström is a Swedish scientist, internationally recognized for his work on global sustainability issues. He is joint director of the Potsdam Institute for Climate Impact Research (PIK) in Germany, together with economist Ottmar Edenhofer. He is also Professor in Earth System Science at the University of Potsdam and Professor in Water Systems and Global Sustainability, Stockholm University.
The contributions of women in climate change have received increasing attention in the early 21st century. Feedback from women and the issues faced by women have been described as "imperative" by the United Nations and "critical" by the Population Reference Bureau. A report by the World Health Organization concluded that incorporating gender-based analysis would "provide more effective climate change mitigation and adaptation."

He is currently Chair of the Intergovernmental Panel on Climate Change (IPCC) for its seventh assessment cycle, and a Professor of Sustainable Energy at Imperial College London. Before being elected as Chair, Skea was Co-Chair of Working Group III of the IPCC. He was a founding member of the UK Government's Committee on Climate Change and currently chairs Scotland's Just Transition Commission. He was a co-author of the IPCC 2018 Special Report on Global Warming of 1.5 °C. In July 2023, Skea was elected as Chair the IPCC.
The Mercator Research Institute on Global Commons and Climate Change (MCC) conducts research and fosters dialogue about how the global commons, such as the atmosphere and the oceans, might be used and shared by many yet nevertheless be protected. In 2021, The International Center for Climate Governance ranks MCC among the top ten think tanks worldwide for the fourth consecutive year.
Andreas Löschel is a German economist currently holding the chair of Energy and Resource Economics at the University of Münster. He is the director of the Centre of Applied Economic Research Münster (CEAW). His research interests include applied microeconomics, energy economics and the economics of climate change. He is ranked among the most influential economists in his field. In an annual Frankfurter Allgemeine Zeitung Ranking, he is among the 25 most influential economists in Germany.
Sérgio Campos Trindade was a Brazilian chemical engineer and researcher, specialist in renewable energies and consultant in sustainable business. Trindade was the coordinating lead author for a chapter of an Intergovernmental Panel on Climate Change (IPCC) report, Methodological and Technical Issues in Technology Transfer (2000); the IPCC as an organization won the 2007 Nobel Peace Prize as a result of its contributors' work.
