Diesel Emissions Reduction Act of 2025
Summary
What This Bill Does
The Diesel Emissions Reduction Act of 2025 is a short reauthorization bill. It amends section 797(a) of the Energy Policy Act of 2005 by replacing 2024 with 2029, extending authorization for the diesel emissions reduction program. That program supports grants, rebates, and related assistance to reduce emissions from older diesel engines and equipment. The bill does not redesign the program; its practical effect is to keep the authorization alive through 2029 so EPA and eligible recipients can continue diesel retrofit, replacement, and emissions-reduction work.
Who Benefits and How
Communities exposed to diesel exhaust benefit if reauthorization supports continued reductions in particulate and nitrogen oxide pollution. Diesel fleet operators benefit from continued eligibility for emissions reduction assistance. State and local clean air agencies benefit from ongoing federal authority for diesel emission projects. School bus and port equipment replacement projects benefit if program authorization continues through 2029.
Who Bears the Burden and How
EPA must continue administering the diesel emissions reduction program under the extended authorization. Federal taxpayers fund grants or rebates supported by the reauthorized program. Diesel equipment owners seeking funds must meet program eligibility and reporting requirements. Congress remains responsible for appropriating any actual program dollars after reauthorization.
