Sierra Club, Partners Sue EPA Over Illegal Repeal of Climate Protections - CleanTechnica

A coalition of health and environmental organizations, including the Sierra Club, American Public Health Association, American Lung Association, and others, has filed a lawsuit against the EPA in the D.C. Circuit Court. The suit challenges the Trump administration’s repeal of the 2009 endangerment finding, which recognized climate pollution as a threat to public health and welfare and formed the basis for vehicle emissions standards aimed at reducing carbon pollution. The repeal also eliminated clean vehicle standards that were projected to deliver the largest reduction in U.S. carbon emissions, save lives, and reduce fuel costs for Americans. The plaintiffs argue that the EPA’s rollback is unlawful and contradicts the Supreme Court’s 2007 Massachusetts v. EPA decision, which affirmed greenhouse gases as air pollutants under the Clean Air Act and mandated EPA to regulate them based on scientific evidence. The lawsuit names EPA Administrator Lee Zeldin and the EPA as defendants, emphasizing the agency’s legal obligation under the Clean Air Act to regulate pollutants that endanger public health.
