The Environmental Protection Agency announced plans to eliminate all federal carbon emissions regulations for the electricity sector, according to a statement released Monday. The action represents a repeal of a 2024 rule implemented by the Biden administration that had required electric utilities to either retire coal-fired power plants during the 2030s or equip them with carbon dioxide capture technology. EPA leadership stated that the repeal would benefit consumers through lower power bills and cited uncertainty in climate science as justification.
The Biden administration’s 2024 rule had represented a shift in strategy following a Supreme Court decision that prevented the federal government from unilaterally forcing utilities to abandon coal. The previous approach, termed the “Clean Power Plan” under the Obama administration, had similarly sought to reduce power sector emissions but faced legal challenges. The repeated reversal of federal coal policy between Democratic and Republican administrations has created regulatory uncertainty that has hindered long-term decarbonization efforts in the electricity sector.
Despite the regulatory back-and-forth, coal power in the United States has declined substantially over the past two decades, driven primarily by the economic advantages of natural gas made cheaper through hydraulic fracturing. However, rising electricity demand from artificial intelligence data centers has created renewed interest in maintaining existing coal plants. Several major utilities, including Southern Company, have extended the operational life of coal facilities to meet this increased power demand, departing from previous retirement schedules.
The repeal is projected to have public health consequences. The Biden rule was estimated to prevent approximately $370 billion in health damages from climate change and air pollution by 2035, including prevention of hundreds of thousands of asthma incidents and over 1,200 premature deaths annually. Coal plants emit hazardous substances including mercury and particulate matter in addition to carbon dioxide.
