Clean car standards legal resources

Date updated: July 2, 2020

Rigorous Clean Car Standards in place since 2012 reduce dangerous pollution while spurring fuel efficiency improvements that save Americans hard-earned money at the gas pump. The Trump administration is trying to roll back these protections and also attacking states’ long-standing authority to carry out more protective standards.

In September 2019, the Trump administration finalized a rule that purports to block states’ well-established clean car authority. The administration is also advancing a damaging roll back of federal clean car standards. EDF is defending clean car standards in court and administrative proceedings.
