Findings Congress finds as follows: (1) The United States and a number of other countries have the stated objective of stabilizing greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. To that end, the United States has pledged to reduce its greenhouse gas emissions by 50 to 52 percent below 2005 levels by 2030. To support that target, the United States has enacted a wide range of policies, including tax incentives, regulations, and funding for greenhouse gas reduction technologies. (2) To achieve this objective, the increase in global mean surface temperature should not exceed 2°C (3.6°F) above preindustrial temperature by 2100 consistent with the Paris Agreement that entered into force in 2016. (3) The risks associated with a temperature increase above 2°C (3.6°F) are grave, including the disintegration of the Greenland ice sheet, which, if it were to melt completely, would raise global average sea level by approximately 23 feet, devastating many of the world’s coastal areas and population centers. (4) A 2018 report by the Intergovernmental Panel on Climate Change demonstrated that limiting the temperature increase to 1.5°C will result in still harmful, but significantly less severe outcomes than a 2°C increase. (5) The Intergovernmental Panel on Climate Change projects that temperatures will rise 1.5°C between 2030 and 2052. In order to limit the temperature increase to 1.5°C, global net anthropogenic carbon dioxide emissions must reach net zero by 2050. The Intergovernmental Panel on Climate Change notes in their 2023 report that the level of reduction in
