Overview
- President Trump and EPA Administrator Lee Zeldin formally scrapped the 2009 finding that greenhouse gases endanger public health, the legal basis for most federal climate rules since 2009.
- The EPA simultaneously eliminated all federal greenhouse-gas standards for vehicles and engines for model years 2012–2027 and beyond, ending related measurement, reporting and compliance programs.
- The administration projects about $1.3 trillion in savings and lower vehicle prices, while critics cite analyses warning of higher pollution, fuel costs and public‑health risks.
- Environmental groups and several states said they will sue, with legal experts noting potential challenges up to the Supreme Court and warning that Congress may need to act to restore federal climate regulation.
- The repeal constrains EPA’s ability to regulate carbon dioxide and methane under the Clean Air Act and could affect future power-plant and industrial rules, even as EPA says it will continue policing traditional tailpipe pollutants.
