Public health, green groups sue EPA over repeal of rule supporting climate protections
Coalition argues EPA repeal of 2009 endangerment finding risks public health and climate protections, threatening decades of federal greenhouse gas regulations.
- On February 18, 2026, APHA and allies sued the EPA and Lee Zeldin in the U.S. Court of Appeals for the District of Columbia Circuit over the rescission of the 2009 endangerment finding.
- The 2009 endangerment finding determined six greenhouse gases harm public health and welfare and served as the legal underpinning for nearly all federal climate regulations under the Clean Air Act.
- EPA analysis found removing vehicle standards will increase gas prices and force Americans to spend more on fuel, while vehicle emissions accounted for 28 percent of U.S. emissions in 2022.
- Plaintiffs contend the EPA's rescission is unlawful and filed the D.C. Circuit challenge to block the action, while 18 children and young adults filed a separate petition, creating uncertainty for businesses.
- Environmental groups warn this rollback is the biggest attack on federal climate authority and say lawsuits could elevate the issue to the Supreme Court, recalling Massachusetts v. EPA .
