The Environmental Protection Agency announced plans to eliminate federal regulations governing carbon emissions from the electricity sector, effectively rescinding the Biden administration’s 2024 rule that required utilities to either retire coal plants during the 2030s or install carbon capture technology. The decision marks another reversal in the decades-long oscillation between Democratic and Republican administrations on coal policy. The EPA justified the repeal by citing uncertainty about climate science and citing potential consumer savings on electricity bills.
Coal remains the world’s most carbon-intensive major energy source, responsible for approximately half of cumulative global carbon emissions since industrialization began. Climate experts widely view transitioning away from coal as among the most impactful measures for addressing global warming. The Biden administration’s rule represented a compromise approach after the Supreme Court blocked the government from unilaterally forcing utilities to abandon coal. Under the repealed rule, utilities could have chosen either path—retirement or carbon capture—to achieve significant emissions reductions from the power sector.
Despite the repeal, coal power has been declining in the United States over the past two decades, primarily due to the shale gas boom making natural gas significantly cheaper than coal. This economic shift has reduced power sector emissions by nearly half without federal mandates. However, recent developments threaten to reverse this trend. Rising demand from data centers and artificial intelligence infrastructure has increased electricity prices, making existing coal plants economically attractive to maintain longer. Several major utilities, including Southern Company, have extended projected retirement dates for coal facilities due to these new market conditions.
The repeal carries substantial public health implications. The Biden administration had projected that its rule would prevent approximately $370 billion in damages from climate change and air pollution by 2035, along with hundreds of thousands of prevented asthma flare-ups and over 1,200 premature deaths annually. Coal plants emit mercury and other harmful toxins alongside carbon dioxide. The frequent policy reversals between administrations, however, have undermined the effectiveness of such regulations in reshaping utility investment decisions and long-term planning, according to environmental economists.
