What it does
This bill would cancel an EPA choice. The choice let California set its own car pollution rules. About 17 other states follow California's car rules. If this bill passes, those states could not enforce their stricter rules. The bill uses the Congressional Review Act to undo the EPA choice.
Who it affects
People in California and states that follow its car rules would be hit. Automakers that build cars would also be hit.
One thing to notice
About 17 states follow California's car rules. Stopping California's waiver could change rules in many states at once. The EPA choice is from 2009. The rule covers cars made after that year.
