EPA Rescinds 2009 Greenhouse Gas Endangerment Finding, Shifting Emissions Rulemaking
The EPA has finalized a major regulatory change by withdrawing its 2009 endangerment finding on greenhouse gases, a move expected to reshape how federal emissions standards are developed under the Clean Air Act.
The Environmental Protection Agency has finalized a rule rescinding a 2009 federal finding that determined greenhouse gases endanger public health and welfare, a decision that had served as the legal foundation for regulating emissions under the Clean Air Act.
The 2009 determination established the basis for federal limits on greenhouse gas emissions from motor vehicles, power plants, and other major sources. With the findings withdrawn, standards built upon that authority will be reconsidered.
EPA officials described the action as a significant regulatory shift that alters how greenhouse gases may be addressed under existing law. The agency said it will evaluate related emissions rules in light of the updated policy.
Public health and environmental experts have previously cited extensive scientific research linking greenhouse gas emissions to climate change and associated impacts. Legal experts have noted that the move could face challenges given prior court decisions affirming federal authority to regulate greenhouse gases.
The change represents a substantial shift in federal environmental regulation and is expected to influence future rulemaking on emissions standards.
