ACEEE filed comments opposing a proposed EPA rule for the Reconsideration of 2009 Endangerment Finding and Greenhouse Gas Vehicle Standards. Greenhouse gas standards for vehicles are key to reducing fuel costs for drivers, reducing air pollution, and avoiding the worst impacts of climate change. Additionally, EPA’s technical bases for the proposed repeal of these rules are insufficient: consumer demand for EVs remains strong and continues to drive industry investment, hybrid technologies and efficiency improvements can deliver significant emissions reductions, and EVs can strengthen the resiliency of the grid. ACEEE urges EPA to maintain strong GHG standards for light-, medium-, and heavy-duty vehicles to protect families, the economy, and the climate.
