The administration of U.S. President Donald Trump is preparing to take another major step toward rolling back environmental regulations by eliminating federal limits on greenhouse gas emissions from power plants. The move would mark a significant shift away from climate policies adopted under previous Democratic administrations, particularly those of Barack Obama and Joe Biden.
The Environmental Protection Agency (EPA) is expected to announce the measure as part of the administration’s broader strategy to reduce regulatory restrictions on the energy sector and encourage greater domestic electricity production from fossil fuels. The Trump administration argues that environmental regulations have increased costs for energy companies and made it more difficult to build and operate power plants.
The rules targeted by the administration were finalized in 2024 under President Joe Biden. They applied primarily to coal-fired power plants and certain new natural-gas-fired facilities. To comply with the requirements, operators could have been required to adopt technologies capable of capturing a portion of their carbon dioxide emissions or to use lower-emission fuels.
The Biden-era regulations were designed to significantly reduce greenhouse gas emissions from the U.S. electricity sector over the coming decades. The power sector is responsible for a substantial share of the country’s climate pollution, making the regulations a key component of Washington’s efforts to address climate change.
The Trump administration, however, argues that removing these limits would give energy producers greater flexibility to meet growing electricity demand. This issue has become increasingly important as the United States experiences rapid growth in electricity consumption, particularly because of the expansion of artificial intelligence, data centers and other energy-intensive technologies.
The administration has promoted what it describes as an era of greater “energy abundance,” arguing that the United States needs to expand electricity generation quickly in order to maintain economic competitiveness. Supporters of the policy say that allowing coal- and gas-fired power plants to operate with fewer restrictions could help stabilize electricity supplies and reduce regulatory costs for producers.
Environmental groups strongly oppose the planned rollback. They warn that eliminating greenhouse gas limits could allow fossil-fuel power plants to release significantly more carbon dioxide into the atmosphere. They also argue that air pollution from power plants can have serious consequences for public health, particularly in communities located close to large industrial facilities.
The controversy also extends beyond carbon dioxide. Power plants can release a range of pollutants that affect air quality and human health. While the administration maintains that certain separate regulations governing hazardous pollutants such as mercury and arsenic will remain in place, environmental organizations fear that the broader rollback of climate regulations could weaken overall environmental protection.
The decision is also likely to trigger a new legal battle. Democratic-led states and environmental organizations have indicated that they could challenge the administration’s action in court. The central legal question will be how far the EPA can go in changing or eliminating federal requirements governing greenhouse gas emissions from power plants.
The dispute comes as the Trump administration continues to dismantle or reconsider several environmental policies introduced under previous Democratic administrations. The broader strategy reflects Trump’s stated preference for expanding domestic fossil-fuel production while reducing what his administration considers excessive federal regulation.
The issue is particularly significant because the United States remains one of the world’s largest greenhouse gas emitters. Any substantial change in regulations governing its power sector could therefore have consequences not only for the American energy market but also for global efforts to reduce emissions and slow climate change.
For environmental advocates, the planned rollback represents a major setback that could make it more difficult for the United States to meet long-term climate objectives. For the Trump administration and its supporters in the energy industry, however, it represents an opportunity to increase electricity production, lower regulatory burdens and strengthen American economic competitiveness.
The planned policy therefore illustrates one of the defining features of Trump’s second-term energy agenda: less federal climate regulation, greater freedom for fossil-fuel producers and a stronger emphasis on expanding domestic energy production, despite concerns over emissions, public health and climate change.
