EPA repeals climate pollution limits for power plants. How will it impact NC?

Most coal- and natural gas-fired power plants in North Carolina no longer will face federal limits on their greenhouse gas emissions, drawing pushback from state leaders and environmental groups.

The Environmental Protection Agency announced on Monday the repeal of a 2024 rule put in place by the Biden administration, which limited greenhouse gas emissions from most existing fossil fuel-fired power plants.

The limits were seen as a key way to curb the United States’ contributions to climate change. Currently, the nation’s power plants emit over 1.5 billion metric tons of greenhouse gases each year. Scientists agree that these gases trap heat in the Earth’s atmosphere, causing rising global temperatures and more frequent extreme weather events.

Under President Donald Trump, the EPA has attempted to shift away from renewable energy and toward fossil fuels, arguing that the greenhouse gas emissions that come from fossil fuel power plants do not pose a significant public health risk. In a Monday news release, the EPA argued that the agency had overstepped its authority under Biden.

Munashe Magarira, a senior attorney for the Southern Environmental Law Center, voiced his criticism of a potential repeal before it was officially announced.

“Given what we’re seeing with weather and climate events across the globe, but also very close to home … it’s a very short-sighted decision,” Magarira said. “It’s very disheartening to see that there’s just a very different assessment of the emergency we face right now.”

It’s unclear whether this repeal would affect each state’s ability to limit greenhouse gas emissions. In North Carolina, the state’s Department of Environmental Quality, not the EPA, reviews greenhouse gas emissions from power plants.

“Once details are released, DEQ’s Division of Air Quality would need to review the proposal to understand how it might impact North Carolina,” DEQ spokesperson Shawn Taylor said in an email before the EPA’s announcement.

What repeal means for Duke Energy

Most of North Carolina’s power plants are owned by Duke Energy, the state’s largest utility company. Duke faces a state-imposed goal to become carbon neutral by 2050, but the state legislature recently eliminated an interim goal for Duke to cut its carbon emissions by 70% by 2030.

Duke Energy spokesperson Craig Wilson said Monday afternoon that the repeal “does not change Duke Energy’s clean energy commitments or long-term planning.”

“We are continuing to modernize our generation fleet based on integrated resource plans and regulatory reviews,” Wilson said. “Those plans already reflect coal retirements and significant investments in new generation to serve our customers.”

Electric utilities across the U.S., including Duke Energy, have spent billions in recent years on retiring fossil fuel-fired power plants and building new renewable power plants in order to prevent dangerous health and climate impacts from carbon emissions. Once built out, clean energy like wind and solar is cheaper to operate in most cases, according to research from the Massachsuetts Institute of Technology and the International Renewable Energy Agency.

EPA administrator Lee Zeldin said in Monday’s press release that “Americans will see a decrease in electricity prices” as a result of the rule repeal. He estimated that the move would save $310 billion, but it’s unclear where those savings will come from.

The rule changes will repeal all greenhouse gas limits for existing fossil fuel power plants that use steam combustion, as well as limits for coal plants and combustion turbines that use carbon capture and storage. The EPA also proposed eliminating all other remaining greenhouse gas emission limits.

The announcement came as Zeldin and other top Trump officials attended the Group of 20 conference in Houston, which is focused on “energy abundance.” The series of economic and policy meetings have included leaders from 19 countries and the African and European Unions. A G20 meeting in Chapel Hill earlier this month drew heated protests outside the University of North Carolina campus.

The EPA first moved to repeal the greenhouse gas limits in June 2025, and proposed to do so by issuing a ruling that fossil fuel-fired power plants “do not contribute significantly to dangerous air pollution.”

In response, leaders from 21 states, four cities and the District of Columbia issued comments calling the rule changes “unlawful, arbitrary and capricious.”

Among them was N.C. Attorney General Jeff Jackson, who “urged the EPA not to take this action because it would harm our state and public health and because it would be unlawful,” said Bailey Aldridge, a spokesperson for Jackson, in an email.

“We’re continuing to monitor this issue,” Aldridge said.
