U.S. EPA Phase 3 Greenhouse Gas Proposal for Heavy-Duty Vehicles
A downloadable summary of the U.S. EPA announced the Phase 3 GHG proposal for heavy-duty vehicles. From 2027 to 2032, 45% reduction in CO2 emissions for light vocational vehicles and 25% for Class 8 sleeper cabs. Over half of light vocational and a quarter of sleeper cabs expected to be ZEVs by 2032.
