The U.S. Environmental Protection Agency has revoked the 2009 endangerment finding that classified greenhouse gases as threats to public health, a move estimated to save over $1.3 trillion but raising concerns about increased climate-related financial burdens on American households.
Background on the Endangerment Finding
- The finding originates from the 2007 Supreme Court case Massachusetts v. EPA, which ruled that greenhouse gases qualify as air pollutants under the Clean Air Act.
- In December 2009, the Obama administration issued the endangerment finding, determining that six greenhouse gases endanger public health and welfare.
- Since then, the EPA has regulated emissions from automobiles, power plants, and other sources.
The Repeal and Estimated Savings
- EPA Administrator Lee Zeldin announced the repeal as the "single largest deregulatory action in U.S. history."
- The agency projects savings exceeding $1.3 trillion by eliminating emission standards for vehicles and engines from model years 2012 to 2027 and beyond.
- Average savings per vehicle: approximately $2,400, including avoided costs for electric vehicle equipment.
- Transportation accounts for about 28% of U.S. greenhouse gas emissions, primarily from fossil fuel combustion in cars, trucks, ships, trains, and planes.
