The Environmental Protection Agency (EPA) announced on September 14 that it will roll back regulations designed to limit greenhouse gas emissions from fossil fuel–fired power plants, reversing measures established under the Biden administration. The move includes rescinding limits on emissions from coal- and gas-fired plants as well as standards regulating mercury and other air pollutants. This comprehensive repeal of remaining greenhouse gas standards for the power sector is expected by the agency to save up to $310 billion.

The announcement came on the first day of a three-day meeting in Houston attended by G20 leaders focused on energy abundance. The United States, as part of its G20 commitments, has expressed a goal of reducing regulatory burdens to promote economic growth and enhance energy independence. EPA Administrator Lee Zeldin has framed the rollback as one of 31 historic deregulation actions initiated since his appointment in March 2025, aimed at removing what the administration considers obstacles to domestic energy production.

Utility industry representatives welcomed the decision, emphasizing its potential to improve the reliability of the nation’s electric grid. They argue that easing emissions regulations will support stable power generation and help meet demand. On the other hand, environmental and public health advocates sharply criticized the rollback, warning that it could lead to increased illnesses and deaths related to pollution, as well as higher long-term healthcare expenses for communities nationwide.

The decision reflects the current administration’s broader skepticism of climate science. President Donald Trump and several Cabinet officials have publicly questioned the validity of climate change, referring to it as a “con job” and a “green scam.” This stance contrasts with warnings from federal and international scientific bodies stressing the importance of lowering emissions to curb global temperature rises. Data show that the past decade has included the 10 warmest years on record worldwide, and the United States recently concluded its hottest meteorological summer in 132 years.

Critics express concern that rescinding these environmental safeguards may exacerbate climate change and its associated impacts on health and the environment. Supporters maintain that the benefits of deregulation, particularly in economic terms and energy supply security, outweigh environmental considerations. The EPA’s latest actions underscore the continuing policy debate over how to balance economic priorities with environmental and public health protections.
