CAFE Standards Analysis
In 2018 the U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) issued a proposal to roll back existing Corporate Average Fuel Economy (CAFE) and tailpipe greenhouse gas (GHG) emission standards for light-duty vehicles to model year 2020 levels. Under the existing CAFE and GHG standards, requirements grow increasingly stringent through model year 2025. On behalf of the California Department of Justice, Synapse evaluated the macroeconomic impacts of the proposed rollback. We found that (1) the agencies' own analysis indicated that the proposed rollback would result in job losses; (2) the proposed rollback would result in reduced vehicle sales; (3) when accounting for broader economic impacts, the proposed rollback would result in greater job losses than those predicted under the agencies' analysis; and (4) the proposed rollback would negatively impact U.S. gross domestic product.
