HB2140, titled the Diesel Emissions Reduction Act of 2025, would amend the Energy Policy Act of 2005 to extend the authorization for the federal diesel emissions reduction program. The bill makes a single substantive change: it replaces the program’s current expiration year of 2024 with 2029, effectively reauthorizing the program for an additional five years.
The measure is a straightforward reauthorization bill and does not create a new program or alter the program’s underlying structure in the text provided. Its practical effect would be to continue federal support for diesel emissions reduction activities, which typically include grants or incentives for replacing or retrofitting older diesel engines and vehicles to reduce pollution and improve air quality.
Impact
If enacted, the bill would amend section 797(a) of the Energy Policy Act of 2005 (42 U.S.C. 16137(a)) by extending the sunset date for the diesel emissions reduction program from 2024 to 2029. This would preserve the existing statutory authority for federal diesel emissions reduction funding and related activities, affecting states, local governments, fleets, and other entities that participate in or benefit from the program.
Sentiment
Based on the bill text and available context, the bill appears to have broad bipartisan support and little visible controversy. It was introduced by members from both parties—Ms. Matsui, Mr. Calvert, Ms. Pingree, and Mr. Langworthy—and there are no recorded committee transcripts or votes indicating opposition. The overall tone is procedural and supportive, consistent with a routine reauthorization of an existing environmental and public health program.
Contention
No specific points of contention are documented in the available materials. Because the bill simply extends an existing program, any debate would likely center on program funding priorities, federal spending, or the effectiveness of diesel emissions reduction efforts, but none of those issues are reflected in the provided transcripts or voting history. The absence of recorded opposition suggests the bill was not yet the subject of substantive disagreement at the stage provided.
