Greenhouse Gas Standards for Heavy-Duty Vehicles Set

The U.S. Environmental Protection Agency today announced final national greenhouse gas pollution standards for heavy-duty vehicles covering model years 2027 through 2032 – the “Greenhouse Gas* Emissions Standards for Heavy-Duty Vehicles – Phase 3.” Heavy-duty vehicles account for 25% of all greenhouse gas emissions from the transportation sector, which is itself the single largest source of greenhouse gas emissions in the United States. Under these new standards, the heavy-duty industry is expected to realize annualized savings of $3.5 billion compared to annualized costs of about $1.1 billion from 2027 through 2055.**

“In finalizing these emissions standards for heavy-duty vehicles like trucks and buses, EPA is significantly cutting pollution from the hardest working vehicles on the road,” said EPA Administrator Michael S. Regan. “Building on our recently finalized rule for light- and medium-duty vehicles, EPA’s strong and durable vehicle standards respond to the urgency of the climate crisis by making deep cuts in emissions from the transportation sector.”

EPA’s most recent modeling shows that the final standards will result in greater reductions of pollution than the proposed rule, while providing more time and flexibility for manufacturers to develop, scale, and deploy clean heavy-duty vehicle technologies. The 1 billion tons of greenhouse gas emissions avoided by these standards is equivalent to the emissions from more than 13 million tanker trucks’ worth of gasoline.

“With this action, the Biden-Harris Administration is continuing to deliver on the most ambitious climate agenda in history while advancing a historic commitment to environmental justice,” EPA said.
