EPA Repeals Biden-Era Power Plant Emissions Limits
The Environmental Protection Agency has repealed Biden-era limits on carbon dioxide emissions from power plants and proposed ending the remaining federal greenhouse gas regulations for the electricity sector.
Under the previous rules, existing coal-fired plants and new natural gas facilities were required to capture or control 90% of their carbon emissions. The EPA identifies power generation as the nation’s second-largest source of carbon dioxide emissions, behind transportation.
The agency’s broader proposal rests on the position that the Clean Air Act does not authorize the federal government to regulate power plant greenhouse gas emissions specifically to address climate change. Because that proposal still requires finalization, its legal and practical effects remain uncertain. An EPA official said the measure was intended to restrict future administrations from using the law to impose climate-focused power plant regulations.
EPA Administrator Lee Zeldin described the rollback as an effort to lower electricity costs for households. The announcement coincided with meetings in Houston involving Zeldin, Energy Secretary Chris Wright, Interior Secretary Doug Burgum and other G20 energy officials. Energy prices and the cost of living are prominent political issues ahead of the November midterm elections, particularly amid higher gasoline and diesel prices linked to the U.S. conflict with Iran.
The action is part of the Trump administration’s broader reversal of climate policies adopted during the Obama and Biden administrations. In February, the EPA also revoked a finding that had classified carbon dioxide as a danger to public health.
The administration has promoted coal, natural gas and oil production while limiting wind and solar projects. Together, these actions mark a change in federal energy and climate policy. The immediate repeal removes Biden-era requirements, while the broader proposal could shape the authority to later administrations. Its final impact will depend on completion of the rulemaking process and legal challenges.
