New York and 20 states sue EPA to block Trump power plant carbon rule repeal

On October 1, 2026, a coalition of 21 states led by New York Attorney General Letitia James, alongside major cities, sued the Trump administration to block the EPA's repeal of Biden-era power plant carbon limits. The coalition petitioned the DC Circuit Court of Appeals, arguing the repeal unlawfully ignores climate and health costs. Conversely, the EPA asserts the rollback will save the utility industry over $300 billion and help unleash American energy.

The EPA's decision to revoke the rule

• ▪The Environmental Protection Agency's rule change for power plants represents a fundamental shift from climate policies enacted under Democratic Presidents Joe Biden and Barack Obama to address greenhouse gas emissions.
• ▪The Environmental Protection Agency announced in September 2026 that it was revoking the Biden-era power plant carbon rule and taking steps to prevent future administrations from regulating climate pollution from power plants.

The multi-state lawsuit against the EPA

• ▪A coalition of 21 states led by New York, along with the District of Columbia, New York City, Chicago, and Denver, filed a federal lawsuit on October 1, 2026, to block the Environmental Protection Agency's repeal of power plant emission rules.
• ▪The coalition challenging the Environmental Protection Agency includes New York, Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New Mexico, North Carolina, Oregon, Rhode Island, Vermont, Washington, Wisconsin, and Pennsylvania's governor.

Arguments against the repeal's environmental impact

• ▪Environmental groups and the multi-state coalition state that the Environmental Protection Agency's repeal of the emissions rule will degrade the environment and come at a direct cost to public health.
• ▪The multi-state coalition argues that dismantling the power plant emissions rule will set the United States back decades and worsen the climate crisis by gutting a significant climate protection.
• ▪New York Attorney General Letitia James stated that the federal government is showing callous disregard for Americans' health and the environment, leaving future generations to pay the price.

The EPA's justification for the repeal

• ▪Environmental Protection Agency Assistant Administrator Aaron Szabo stated in September 2026 that the repeal allows utilities to make decisions for ratepayers based on cost savings rather than being forced to shut down facilities.
• ▪The Environmental Protection Agency stated that repealing the power plant rule would save the utility industry more than $300 billion in costs and help unleash American energy.

Power plant emissions

• ▪The 2024 Carbon Pollution Standards required United States power plants to reduce their greenhouse gas emissions by installing carbon capture technology.
• ▪Power plants are the second largest source of United States greenhouse gas emissions after vehicles, accounting for approximately one-quarter of the nation's carbon dioxide emissions.

Debatable claims

• ▪Mandating carbon capture technology for power plants is economically unfeasible
• ▪The EPA must regulate greenhouse gas emissions from gas-fired power plants
• ▪The EPA's repeal of power plant carbon limits is justified
• ▪The EPA lacks the authority to block future power plant regulations
