Climate Impacts of the EPA’s Proposed Vehicle Emissions Rule
Earlier this month, the Environmental Protection Agency (EPA) published the first of what promises to be several rulemakings aimed at reducing greenhouse gas emissions from the transportation sector. In a new insight, AAF’s Director of Regulatory Policy Dan Bosch assesses the climate impacts of the EPA’s proposed vehicle emissions rule and the implications for future rulemakings.
Bosch’s key points:
- The EPA’s recent proposed rule on greenhouse gas emissions from light-duty vehicles is the first of several expected rulemakings targeting the transportation sector in an effort to help the United States meet its goal of reducing nationwide emissions 50 percent from 2005 levels by 2030;
- The proposed rule projects only modest emissions reductions, setting standards that are essentially equivalent to those adopted by the Obama Administration nearly a decade ago; and
- The modest reductions stemming from this proposed rule mean more substantial emissions cuts will have to come from future rulemakings – at likely record-breaking costs.
