US EPA considering two-year delay in enforcing Biden vehicle pollution rule


WASHINGTON, Dec 11 - The U.S. Environmental Protection Agency is considering delaying enforcement of ⁠a Biden-era regulation requiring ⁠significant cuts in air pollution ‍from vehicles, a senior agency official told Reuters.

In April 2024, the EPA finalized a rule requiring significant reductions in so-called "criteria pollutants" emitted from passenger and commercial vehicles including nitrogen oxides from ;the 2027 through 2032 ‍model years. The EPA is ‍considering keeping the 2026 standard in place for two additional years to give the ⁠agency time to reconsider ‍the Biden-era ​standards and how the agency sets standards. The EPA has separately proposed revoking ;the scientific ⁠finding that ‍justified setting greenhouse gas emission standards ‍for light-duty, medium-duty, and ;heavy-duty ‍vehicles and ​engines.
