The U.S. Environmental Protection Agency (EPA) has finalized the repeal of Biden-era greenhouse gas emissions standards for power plants, marking a major shift in U.S. climate and energy policy. The Trump administration says eliminating the regulations could remove more than $300 billion in projected industry costs, reduce regulatory burdens and help expand reliable American energy production. Supporters say the move will give coal and natural-gas power producers greater flexibility as electricity demand rises, while environmental groups warn that rolling back carbon restrictions could increase greenhouse gas emissions and climate-related impacts. The EPA maintains that other federal and state pollution controls remain in place. The decision is expected to face legal and political challenges, making the EPA power plant emissions rule repeal a major story for the U.S. energy, manufacturing and industrial sectors.
