Environmental and public health groups sued the Trump administration on Thursday, challenging the Environmental Protection Agency's rollback of carbon emission limits for fossil fuel-fired power plants established by the Biden administration. Six organizations, including the Natural Resources Defense Council and American Lung Association, filed a lawsuit in the U.S. Court of Appeals for the D.C. Circuit, arguing that the EPA violated its obligations under the Clean Air Act. The EPA countered that the rollback would save an estimated $310 billion in compliance costs while ensuring reliable energy supply.

Story summary
Environmental and public health groups sued the Trump administration in August 2023 over the rollback of Biden-era limits on carbon emissions from fossil fuel-fired power plants. The lawsuit was filed by organizations including the Natural Resources Defense Council, American Lung Association, and others, arguing that the Environmental Protection Agency (EPA) violated its obligations under the Clean Air Act by repealing the standards without providing replacements. Three days prior to this legal action, the EPA had finalized a partial repeal of carbon pollution standards set in 2024. The agency claimed this move would reduce regulatory costs and save an estimated $310 billion in compliance costs while enhancing electric-grid reliability. Meredith Hankins from NRDC criticized the EPA’s actions as an "abdication" of its legal responsibility to protect public health and the environment.

Environmental and public health groups sued the Trump administration Thursday over the Environmental Protection Agency’s rollback of Biden-era limits on carbon emissions from fossil fuel-fired power plants.
asserted
groups → sue → plants
The Natural Resources Defense Council, American Lung Association, American Public Health Association, Clean Air Council, Clean Wisconsin, and Environmental Defense Fund filed the lawsuit in the U.S. Court of Appeals for the D.C. Circuit, arguing the EPA violated its obligations under the Clean Air Act by repealing the standards without replacing them.
asserted
EPA → file → them
The lawsuit comes three days after the EPA finalized a partial repeal of the Biden administration’s 2024 carbon pollution standards.
asserted
EPA → come → standards
The agency said the move would reduce regulatory costs, strengthen electric-grid reliability, and save an estimated $310 billion in compliance costs.
asserted
move → say → costs
The EPA separately proposed eliminating the remaining greenhouse gas standards for power plants.
asserted
EPA → propose → plants
“Repealing these standards without a replacement is an abdication of EPA’s legal responsibility to protect public health and the environment,” Meredith Hankins, federal climate legal director at NRDC, said Thursday.
asserted
Hankins → repeal → NRDC
“The Clean Air Act and Supreme Court precedent demand that the EPA address climate pollution from the largest industrial source in the nation.”
asserted
EPA → demand → nation
The groups also argued that power plant emissions pose significant health risks.
asserted
emissions → argue → risks
“Clean air is a basic human right,” said Georges C. Benjamin, CEO of the American Public Health Association.
asserted
Benjamin → say → Association
He said power plant pollution threatens millions of Americans and that weakening the standards would particularly affect children, pregnant people, and communities already facing high levels of pollution.
asserted
weakening → say → pollution
American Lung Association President and CEO Harold Wimmer said power plant emissions contribute to climate change and that reducing carbon emissions can also reduce other pollutants harmful to lung health.
asserted
reducing → say → health
The EPA has defended the rollback as a way to expand access to reliable, affordable energy since it was announced on Monday.
asserted
it → defend → Monday
“For over 15 years, the Obama and Biden administrations implemented a war on coal to destroy reliable and affordable energy,” EPA Administrator Lee Zeldin said Monday.
asserted
Zeldin → implement → energy
“The Trump Administration has come in to protect American energy and to make sure you can afford to keep the lights on.”
asserted
you → come → lights
Under the final rule, new coal-fired power plants will remain subject to standards established in 2015.
asserted
plants → fire → 2015
New natural gas plants will also remain subject to the 2015 standards and certain efficiency requirements established in 2024.
asserted
plants → remain → 2024
The Biden-era rules required existing coal plants and new natural gas plants to meet carbon pollution limits based on technologies such as carbon capture.
asserted
rules → require → capture
The Trump EPA said repealing those requirements would reduce compliance costs and preserve energy options as electricity demand grows.
asserted
demand → say → options
The dispute is the latest chapter in a yearslong legal battle over EPA authority to regulate greenhouse gas emissions from power plants.
asserted
dispute → regulate → plants
The Supreme Court limited that authority in its 2022 West Virginia v. EPA ruling, after which the Biden administration crafted its 2024 regulations.
asserted
administration → limit → regulations
Now, environmental groups are asking the D.C. Circuit to block the Trump administration’s rollback, setting up another legal fight over the scope of federal authority to regulate power plant carbon emissions.
asserted
groups → ask → emissions
