EPA air officials said Tuesday they’re in the early stages of additional regulations related to conventional and greenhouse gas emissions from tailpipes. The agency says it is on track to propose new federal light-duty standards sometime next month to replace the Trump rollback, but the Biden administration also is looking even further forward.

Alejandra Nunez, the deputy assistant administrator for mobile sources in the air office, told a virtual gathering of transportation advisers on Tuesday that post-2026 standards are “a priority for us” and that a firmer timeline could come “in the next few months.”

Keep on truckin’: Acting EPA air chief Joe Goffman also promised action on the long-delayed truck nitrogen oxide rule, formally known as the Cleaner Trucks Initiative, which would strengthen nitrogen oxide emissions limits. Administrator Michael Regan is working with the air office on a strategy for the heavy-duty trucking sector, to debut in the “not-too-distant future,” Goffman said.
