The US Environmental Protection Agency is set to roll back key climate standards for power plants, signalling a significant shift in federal environmental policy and renewing industry uncertainty over decarbonisation strategies.
The US Environmental Protection Agency is preparing to unwind former President Joe Biden’s power-plant climate standards in two stages, according to people briefed on the administration’s plans, with the first move expected within the next two months.
The agency’s opening argument is likely to centre on a technical claim with major policy consequences: that carbon capture and natural gas co-firing are not credible decarbonisation routes for the country’s coal-fired fleet. Industry insiders say that line of reasoning would be used to justify scrapping the 2024 rule, which imposed greenhouse-gas limits on power plants.
A second step could follow quickly or arrive later. According to people familiar with the discussions, EPA is considering a separate proposal that would go further and restrict the agency’s future regulatory reach, echoing its recent attempt to roll back the endangerment finding. That broader move would not be final immediately; it would first go out for public comment and then require another rulemaking process before being completed.
The timing matters for utilities and industrial power users trying to plan for long-lived assets. If the repeal proceeds as expected, it would create another sharp swing in federal climate policy for the power sector, after years of back-and-forth between administrations over the scope of EPA authority under the Clean Air Act.
EPA has already moved aggressively against Biden-era power-sector rules. In a separate announcement, the agency said it had finalised repeal of the 2024 amendments to the Mercury and Air Toxics Standards for coal- and oil-fired power plants, describing that action as a way to cut costs for households. The agency has also proposed scrapping all greenhouse-gas standards for the power sector, arguing that doing so would support affordable and reliable energy while reducing regulatory burdens.
The broader regulatory reset follows an earlier pattern. In 2019, the Trump administration repealed the Clean Power Plan and replaced it with the more limited Affordable Clean Energy rule, before the Biden administration restored a more aggressive climate framework for power plants.
For industrial decarbonisation professionals, the likely consequence is not just a change in federal compliance costs, but renewed uncertainty over the investment case for carbon capture, gas co-firing and other emissions-control strategies that depend on a stable policy horizon.
