The Environmental Protection Agency (EPA) under Administrator Lee Zeldin has announced plans to rescind greenhouse gas emissions standards for the power sector, marking a significant shift in federal climate policy. The rollback affects regulations established during the Biden administration aimed at reducing carbon dioxide emissions from electricity generation.
The United States is the world’s second-largest emitter of greenhouse gases, trailing only China. According to preliminary figures from the Department of Energy’s Energy Information Administration (EIA), the electric power sector released approximately 1,485 million metric tons of carbon dioxide in 2025. This total includes emissions from the burning of coal and natural gas, the latter primarily composed of methane. The power sector represents the nation’s second-largest source of CO2 emissions after transportation.
The standards being withdrawn had been projected to cut emissions by about 1 billion metric tons by 2047, contributing to broader efforts to mitigate climate change. The regulations also played a major role in accelerating coal plant retirements, which were instrumental in lowering pollutants linked to negative health outcomes.
Government officials celebrated the move, with Interior Secretary Doug Burgum describing it as a return to “common sense energy solutions” that would save Americans money by rolling back what he termed the “Green New Scam policies” of the previous administration. Zeldin emphasized the balance the administration aims to strike between environmental protection and economic growth, asserting that the change would support important infrastructure projects while safeguarding public health.
The Edison Electric Institute, representing investor-owned electric utilities, supported the repeal. Chief Legal Officer Rachael Marsh said regulatory certainty helps utilities plan for future investments that ensure grid reliability and cost-effectiveness amid rising electricity demand. The group expressed willingness to collaborate with the EPA on developing new regulatory frameworks.
However, the rollback has elicited sharp criticism from environmental and health advocacy groups, who argue that the decision will lead to increased pollution, higher health care costs, and more expensive energy for consumers. Climate Power described the policy shift as favoring profits for fossil fuel interests at the expense of public health, while Moms Clean Air Force warned that the move undermines efforts to protect vulnerable populations from the worsening impacts of climate change.
Zealan Hoover, a senior adviser to former EPA Administrator Michael Regan, warned that ending these regulations would halt federal oversight of power sector climate pollutants entirely and potentially worsen health outcomes due to higher emissions. Advocates underscored the scientific consensus linking human greenhouse gas emissions to climate change, emphasizing the urgency of maintaining strong regulatory measures to curb environmental and public health risks.
The rollback represents a major departure from recent federal climate strategies and is expected to reshape the trajectory of U.S. efforts to reduce emissions from the energy sector in the coming decades.
