The Trump Administration finally released in March its long-planned rollback of federal fuel economy standards, a gift to the oil industry and its allies. However, the rollback is riddled with errors that will lead to a lengthy court battle and could be halted by a new president next January. Furthermore, long-term industry trends and international efforts to promote cleaner vehicles may make the rollback meaningless.

I detail the administration’s rule-making and the potential for more optimistic outcomes in a new opinion piece published today by the Regulatory Review at University of Pennsylvania Law School. The stakes for the climate fight, given the centrality of transportation emissions to overall greenhouse gas emissions, couldn’t be higher.
