The Environmental Protection Agency has made a major shift in federal climate policy for the power sector, reversing course on rules adopted in 2024 for fossil fuel-fired generators. On September 14, 2026, the agency said it had finalized a repeal of key carbon pollution standards for coal- and gas-fired power plants and proposed scrapping the remaining greenhouse gas limits for those facilities.
EPA action rolls back 2024 standards
The EPA said Administrator Lee Zeldin signed the final partial repeal on September 14, according to the agency’s rule page and a same-day EPA news release. The agency said the action repeals most of the 2024 Carbon Pollution Standards for fossil fuel-fired electric generating units and is paired with a supplemental proposal to remove the remaining greenhouse gas standards for coal and gas plants under Section 111 of the Clean Air Act. The EPA said the final repeal and broader proposal together would reduce compliance costs for the industry by more than $300 billion.
The rollback targets rules finalized on April 25, 2024, during the Biden administration. Those standards had required certain existing coal plants and some new natural gas plants to control carbon dioxide emissions, with EPA at the time pointing to carbon capture and storage as a compliance pathway. In its current action, the agency said it no longer views those requirements as legally supportable in light of the Supreme Court’s decision in West Virginia v. EPA and related case law.
The Associated Press reported that the EPA also took a separate step intended to limit future administrations’ ability to regulate greenhouse gas emissions from power plants. In a technical fact sheet, the agency said it is proposing to rescind the legal findings underpinning those power-sector greenhouse gas rules. That proposal is not yet final.
The immediate effect is national because the rule applies across the U.S. power fleet, not to one state or utility. According to the U.S. Energy Information Administration, natural gas produced about 41% of U.S. electricity in 2025 and coal produced about 17%, meaning the repeal reaches generators that still account for a majority of the country’s power supply. That makes the policy change especially significant in states with large fleets of gas-fired units and in regions that continue to rely on coal for dispatchable power.
What is not yet known is the full plant-by-plant impact. The EPA has not released a comprehensive public list, in its repeal announcement, of every individual facility that will see compliance obligations lifted or delayed as a result of the September 14 action. Some requirements were repealed immediately, while other remaining standards are only subject to a supplemental proposal and will go through further rulemaking before any broader changes take effect.
That means utilities, grid operators and state regulators are still sorting through what changes, and when. EPA materials indicate the agency expects the repeal to ease pressure on coal generation and support new gas development, but the timing of any investment, retirement or construction decisions will still depend on fuel prices, electricity demand, state rules and possible court challenges.
The EPA rooted its decision in legal arguments and energy market policy. In its prepublication supplemental proposal, the agency said Section 111 of the Clean Air Act does not authorize power plant greenhouse gas regulation in the way the 2024 standards attempted, and it cited the Supreme Court’s major questions doctrine analysis in West Virginia v. EPA. Axios reported that the administration’s broader strategy is to make that interpretation harder for a future administration to reverse.
The agency also framed the repeal as an economic measure. EPA said the action would “unleash” coal and natural gas generation and lower regulatory burdens on baseload power plants. In its technical fact sheet, the agency said coal use in the power sector could increase sharply if the repeal remains in place, while its Annual Energy Outlook 2026 shows coal’s long-term share remains higher in scenarios where greenhouse gas limits on power plants do not stay in effect.
For households and businesses, the most immediate takeaway is that this does not change electric service overnight. Customers should expect the rule fight to continue through public comment, possible litigation and additional federal action before the longer-term regulatory picture is settled. For now, the September 14 final repeal removes major 2024 federal climate requirements for coal and gas plants, while the broader effort to erase the rest of the sector’s greenhouse gas standards is still pending.
