EPA is moving to repeal the 2024 carbon emissions standards for US power plants and to block future administrations from writing new CO2 limits for fossil fuel generation. White House review of the final rule and a related proposal is complete, and the agency could announce the plan as soon as September 14, 2026. Electricity generation is the second largest source of US carbon emissions, and demand has been rising after years of flat growth. EPA is expected to argue that the Clean Air Act does not authorize direct regulation of power plant CO2, mirroring the earlier repeal of the endangerment finding for vehicles. Critics call that inconsistent, while supporters of the repeal say the Biden-era rules relied on carbon capture that is not commercially viable at scale. The rule will likely face court challenges, with the vehicle endangerment repeal already in litigation.
