The U.S. Environmental Protection Agency (EPA) has published its strongest-ever U.S. greenhouse gas (GHG) standards for heavy-duty vehicles. The agency estimates the standards will reduce GHG emissions by 1 billion tons, equivalent to the emissions from more than 13 million tanker trucks’ worth of gasoline.

Published on 29 March 2024, “Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles - Phase 3” cover model years (MY) 2027 through 2032. These standards build upon the previous Phase 2 standards established in 2016 and aim to significantly reduce carbon dioxide (CO2) emissions from heavy-duty vehicles, aligned with the completion of The Clean Trucks Plan.
