Need to Know
- EPA’s final rule repeals most provisions of the 2024 Carbon Pollution Standards for fossil fuel-fired power plants.
- The action removes guidelines for existing steam-generating units and certain carbon-capture-based requirements.
- A separate proposal would repeal the remaining standards, while the final partial repeal takes effect Nov. 16.
The U.S. Environmental Protection Agency has finalized a partial repeal of the 2024 Carbon Pollution Standards for greenhouse gas emissions from fossil fuel-fired power plants.
The final rule repeals emission guidelines for existing fossil fuel-fired steam-generating units, carbon capture and sequestration or storage requirements for coal-fired units undergoing large modifications and Phase 2 carbon-capture-based standards for new baseload stationary combustion turbines.
The action does not remove every greenhouse gas standard for the power sector. The 2024 efficiency-based standards for new stationary combustion turbines remain in place under the final rule.
EPA separately issued a supplemental proposal that would repeal the remaining greenhouse gas standards for fossil fuel-fired electric generating units under Section 111 of the Clean Air Act. That proposal will proceed through a separate public-comment process.
The final partial repeal was published in the Federal Register Sept. 17 and becomes effective Nov. 16.

Although the rule regulates power plants rather than coatings facilities, changes in power-sector requirements can affect electricity costs, decarbonization planning and investment decisions across energy-intensive manufacturing. PCI follows these developments as part of its coverage of industry regulations and standards.
