Diesel Emissions Reduction Act of 2025

HR 2140, the Diesel Emissions Reduction Act of 2025, extends the expiration date of the existing Diesel Emissions Reduction Act program. It amends Section 797(a) of the Energy Policy Act of 2005 by changing the end date from 2024 to 2029. This bill does not create new programs or funding; it simply prolongs the current program's authorization period. The change affects the continuation of the existing federal program that supports state and local efforts to reduce diesel emissions from older vehicles.
