President Donald Trump’s administration repealed a rule forcing states to comply with a policy monitoring greenhouse gas levels from tailpipes of American automobiles.
The Federal Highway Administration (FHWA) signed a final rule May 22 that eliminates a mandate requiring state agencies to establish emission targets, calculate their progress toward those targets, and determine a plan of action if they failed to make progress during a performance period.
The rule repealed the performance management measure assessing the percent change in tailpipe carbon dioxide emissions on the Greenhouse Gas (GHG) measure. It also measured total annual tons of carbon emissions from all on-road mobile sources.
States and other locals across the country can still pursue similar actions locally. The repeal of the GHG measure does not affect implementation of the other national performance management measures states are responsible for administering.
This is one of several regulations Trump’s administration has sought to rollback.
Trump announced in April preparations to scrap an Obama-era rule that would have dramatically ratcheted up fuel efficiency guidelines over the course of a decade. The plan would also target California’s ability to set its own vehicle efficiency standards.
