Bipartisan Legislation Passes in Unanimous Vote
Washington, DC, Sept. 02, 2026 – The Engine Technology Forum (ETF) applauded the House Energy and Commerce Committee for passing H.R. 2140, the Diesel Emissions Reduction Act (DERA) of 2025. This legislation received a unanimous vote, marking a significant step toward reauthorizing DERA, which amends the Energy Policy Act of 2005.
“We recognize and thank Representatives Matsui (D-CA) and Langworthy (R-NY) for their leadership in sponsoring the legislation, and all members of the House Energy and Commerce Committee who supported it,” said Allen Schaeffer, executive director of ETF.
DERA’s Impact
The DERA program has been a bipartisan success due to its structure, competitive process, and ongoing need for funding. According to the U.S. Environmental Protection Agency’s (EPA) Sixth Report to Congress, DERA has enhanced numerous technologies, benefiting various sectors including marine, rail, and public transport.
DERA provides funding to expedite the upgrade or retirement of older diesel engines, with a focus on projects that address emissions in areas suffering from poor air quality. The program has faced overwhelming demand, with funding requests exceeding available resources annually.
Future Considerations
H.R. 2140 aims to reauthorize DERA through 2029, fostering collaboration among manufacturers, fleet operators, and community organizations to reduce diesel emissions effectively.
“We look forward to the consideration of H.R. 2140 by the full House of Representatives,” noted Schaeffer.
