The United States Environmental Protection Agency has formally repealed major federal regulations that restricted greenhouse gas emissions from coal-fired and natural gas-fired power plants. The sweeping move unravels decades of environmental standards designed by previous administrations to curb the atmospheric pollutants that scientists identify as the primary drivers of global warming.
EPA Administrator Lee Zeldin announced the policy reversal on Monday during a press conference in Houston, Texas. Zeldin characterized the deregulation as a direct response to public demand for reduced federal oversight, framing the decision as an effort to eliminate administrative hurdles and accelerate the construction of new domestic energy generation facilities.
According to agency projections, rescinding these emission caps will eliminate more than $300 billion in regulatory and compliance expenses for power plant operators. Administration officials stated that lifting the mandates gives utility providers the flexibility to make economical choices for their consumers rather than being compelled by federal rules to retire older or less efficient power stations.
Alongside the immediate repeal, the EPA introduced an additional proposed rule that it expects to finalize next year. This secondary measure is specifically crafted to establish regulatory roadblocks that would hinder future administrations from reinstating federal limits on greenhouse gas pollution from power generation facilities.
The announcement coincided with a G20 ministerial gathering on "energy abundance" held in Houston. Delivering the policy shift in Texas served as an intentional showcase of the state's traditional energy sector, while also marking a notable divergence from European and other international allies participating in the summit who continue to implement climate-focused energy transitions.
The regulatory rollback represents a key component of President Donald Trump’s agenda to expand domestic energy production following his return to office in 2025. Trump, who previously described climate change as "the greatest con job ever perpetrated on the world" during a speech to the United Nations, has repeatedly committed to unleashing American energy resources and previously withdrew the nation from the 2015 Paris climate accord for a second time.
The administration’s emphasis on expanding conventional fuel infrastructure comes amid persistent volatility in fuel markets linked to the ongoing war involving Iran. Domestic retail gasoline prices have climbed past $4.31 per gallon, or roughly $1.14 per liter, marking an increase of over one dollar compared to prices recorded twelve months prior.
The power plant decision follows an extensive deregulatory campaign initiated by Zeldin in early 2025, when the EPA targeted nearly three dozen environmental rules in what the agency chief hailed as the most consequential single day of deregulation in United States history. Zeldin maintained that the administrative shifts were required to dismantle policies from the Barack Obama and Joe Biden administrations that he argued had constrained domestic energy supplies.
A central precursor to Monday's action occurred in February, when the EPA revoked a foundational 2009 scientific endangerment finding. That scientific determination had formally concluded that carbon dioxide and other greenhouse gases pose a danger to public health and general welfare, providing the essential legal basis for regulating emissions across motor vehicles, power stations, and industrial facilities.
At the time of that February decision, Trump praised the revocation as the single largest deregulatory action in the nation's history. That repeal promptly triggered a lawsuit from public health and environmental advocacy groups, who argued that abandoning the underlying science endangered the safety and welfare of the American public.
Monday's repeal of power sector emission rules has drawn similarly fierce pushback from climate and legal organizations. Maggie Coulter, an attorney with the Climate Law Institute at the Center for Biological Diversity, sharply criticized the administration for disregarding a major portion of the nation's carbon footprint, warning that ignoring a quarter of the country's climate pollution will result in increased casualties and heighten the severity of heatwaves, storms, and wildfires.
Elected officials also condemned the agency's rollback. Democratic Senator Patty Murray of Washington state issued a statement criticizing the move, arguing that granting power plants unrestricted pollution limits poses grave health hazards to families and threatens the nation's air and water quality while urging the public to resist the rollback.
Environmental groups further stressed that the EPA has an enduring legal obligation to safeguard the population from harmful air pollution. Vickie Patton, general counsel for the Environmental Defense Fund, warned that removing safeguards against power plant pollution will inflict severe costs on public health and safety at a time when communities are already grappling with extreme heat, destructive storms, flooding, and rising insurance expenses.
Patton added that cost-effective and dependable clean energy technologies are readily available to supply electricity to homes and businesses across the country. With environmental and public health advocacy organizations pledging immediate court challenges, the rollback is set to become the focus of a prolonged legal battle over the federal government’s authority to regulate industrial emissions.
