President Donald Trump's administration on Tuesday proposed revoking a scientific finding that has long been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change.

On July 29, 2025, EPA proposed that the Clean Air Act (CAA) does not authorize the agency to promulgate greenhouse gas (GHG) emission standards to address climate change, thereby rescinding EPA's 2009 "Endangerment Finding" that GHG emissions contribute to air pollution endangering public health or welfare.

The Trump administration’s goal is to roll back rules limiting planet-warming greenhouse gas emissions from power plants, vehicles and oil and gas production, but it could backfire for industry.
