AI-Generated Summary

Updated September 22, 2026 at 5:43 AM UTC

The Diesel Emissions Reduction Act of 2025 updates the Energy Policy Act of 2005 by extending the authorization period for the diesel emissions reduction program. It changes the program’s end date from 2024 to 2029, allowing the program to continue operating and providing funding for diesel emission reduction projects. This affects agencies that run the program and the entities that receive its grants, such as state and local governments and private firms working on diesel emission controls.

Key Provisions

  • Amends Section 797(a) of the Energy Policy Act of 2005 to replace the year “2024” with “2029,” thereby reauthorizing the diesel emissions reduction program through 2029.
