"WASHINGTON - The U.S. Environmental Protection Agency (EPA) will consider adopting more stringent greenhouse gas emissions rules for heavy trucks after Congress passed new incentives to speed the adoption of zero-emission vehicles, the agency told Reuters.

In March, the EPA proposed new rules to cut smog-forming and greenhouse gas (GHG) emissions from heavy-duty vehicles. The agency said it will reopen the proposed GHG rules after passage in August of the climate and spending Inflation Reduction Act, a move that could speed the U.S. shift to electric heavy-duty vehicles.

The EPA will be issuing a supplemental notice of proposed rulemaking to consider more stringent GHG standards for model years 2027 through 2029 in December.

EPA Office of Air and Radiation official Joseph Goffman told Reuters "the big change here is the Inflation Reduction Act. Congress definitely sent a very strong message backed by significant resources.""
