Background
On July 29, 2025, the Department of Energy (DOE) published a report entitled A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate, evaluating existing peer-reviewed literature and government data on climate impacts of Greenhouse Gas (GHG) Emissions and providing a critical assessment of the conventional narrative on climate change.
Among the key findings, the report concludes that carbon dioxide (CO2) -induced warming appears to be less damaging economically than commonly believed, and that aggressive mitigation strategies could be more harmful than beneficial. Additionally, the report finds that U.S. policy actions are expected to have undetectably small direct impacts on the global climate and any effects will emerge only with long delays.
The report was developed by the 2025 Climate Working Group, a group of five independent scientists assembled by Energy Secretary Chris Wright with diverse expertise in physical science, economics, climate science and academic research.
