This bill would keep a federal program for cutting diesel engine pollution alive for five more years. It extends the program’s legal approval through 2029, but it does not provide the money by itself.
Modern Action explains what the legislation does, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.
Diesel Emissions Reduction Act of 2025 is a House bill in committee. The latest recorded action: Forwarded by Subcommittee to Full Committee by Voice Vote.
Latest action on H.R. 2140: Forwarded by Subcommittee to Full Committee by Voice Vote.
Who this affects: This bill mainly affects groups that use or plan to use the federal diesel emissions reduction program. That includes states, tribes, local governments, and owners of diesel equipment. It also matters for communities near diesel traffic or equipment, since the program supports projects meant to reduce air pollution.
Why this matters: Diesel engines can add pollution to the air, and this bill keeps one federal tool available to help reduce it. Without this extension, the program’s legal approval could lapse. That could make it harder for states, tribes, local governments, and equipment owners to plan diesel upgrade projects. The bill creates more time, but it does not promise future funding.
