H.R. 2140: Diesel Emissions Reduction Act of 2025

The bill known as the Diesel Emissions Reduction Act of 2025 aims to amend an existing law to extend the funding and operation of the diesel emissions reduction program. Specifically, it reauthorizes this program until the year 2029, instead of having it expire in 2024. The diesel emissions reduction program is designed to provide funding for projects that help reduce emissions from diesel engines, which can contribute to air pollution and health issues.

Through this reauthorization, the program will likely continue to support initiatives aimed at improving diesel engine technologies, funding retrofits, and promoting cleaner practices in various industries that rely on diesel-powered vehicles and equipment. This may include grants to states and local governments to upgrade or replace older diesel engines, leading to potential reductions in harmful emissions and improved air quality.

This bill was introduced in the U.S. House of Representatives and has been referred to the Committee on Energy and Commerce for review. By extending the program's lifespan, the bill affirms the government's commitment to tackling diesel emissions and supporting efforts to transition to cleaner technologies.
