From the Document: "On August 5, 2021, the Biden Administration proposed amendments to the federal standards that regulate fuel economy and greenhouse gas (GHG) emissions from new light-duty vehicles--a category that includes passenger cars and most sports utility vehicles, vans, and pickup trucks. These standards include the Corporate Average Fuel Economy (CAFE) standards promulgated by the National Highway Traffic Safety Administration (NHTSA) and the Light-Duty Vehicle GHG emission standards promulgated by the U.S. Environmental Protection Agency (EPA). President Biden also signed Executive Order 14037, 'Strengthening American Leadership in Clean Cars and Trucks,' which (1) requires EPA and NHTSA to begin work on future rulemakings for multipollutant and fuel efficiency standards for both light-duty vehicles and heavy-duty vehicles and engines that would take effect beginning in model year (MY) 2027, and (2) sets a nonbinding electrification goal that '50 percent of all new passenger cars and light trucks sold in 2030 be zero-emission vehicles, including battery electric, plug-in hybrid electric, or fuel cell electric vehicles.'"
