The U.S. Environmental Protection Agency announced in September that it would relinquish its regulatory authority over greenhouse gas emissions from power plants under the Clean Air Act. This action effectively eliminates emissions limits on coal and gas facilities and reduces federal capacity to constrain such pollution. The agency estimates the decision will result in an additional 123 million metric tonnes of carbon dioxide entering the atmosphere over the next decade.
The move reverses standards that were established in 2024 and had been projected to reduce greenhouse gas emissions by 1 billion tonnes by 2027 while generating $370 billion in net benefits. Those earlier standards were also anticipated to prevent approximately 1,200 premature deaths and 360,000 asthma attacks annually by 2035 through air quality improvements. The EPA’s current analysis estimates the rollback will save power plant operators $370 million in compliance costs but does not include financial valuations of prevented deaths and health improvements in its calculations.
The decision represents one of several recent environmental regulatory changes by the Trump administration. Earlier in the year, the EPA overturned the 2009 endangerment finding that identified greenhouse gases as a significant threat to public health and the environment. In February, the agency also eliminated pollution standards for vehicles. EPA Administrator Lee Zeldin characterized the power plant decision as ending the “war on coal” and stated Americans would experience lower electricity prices, emphasizing job creation and economic growth potential.
The EPA statement accompanying the announcement claimed that greenhouse gas emissions from power plants have no material impact on global climate change. This position contradicts established climate science, including recent research documenting that climate change from greenhouse gas emissions over the past 70 years has caused a 36 percent decline in mountain snowpacks in Western U.S. states. Electricity generation accounts for approximately one quarter of U.S. greenhouse gas emissions and would rank as the world’s fifth-largest carbon polluter if considered independently.
Environmental organizations responded with legal challenges and criticism. The decision arrives as the United Nations has warned that global warming is on track to exceed the 1.5 degrees Celsius target, with expected consequences including increased extreme weather events, glacier melt, rising sea levels, and potential disruption of critical ocean circulation systems. The Trump administration’s regulatory actions contrast sharply with international climate initiatives and efforts by other nations to reduce emissions.
