What this bill would do

This bill is known as the Diesel Emissions Reduction Act of 2025. It amends the Energy Policy Act of 2005. The main purpose of the legislation is to reauthorize the diesel emissions reduction program. It does this by changing the year in Section 797(a) of the Energy Policy Act of 2005 from 2024 to 2029. The bill was passed by the House of Representatives on September 15, 2026, and was received and placed on the Senate calendar on September 16, 2026.

What Congress actually voted on

One recorded vote has been taken on this bill.

  • The House: a fast-track vote, needing two-thirds to passPassed 343–79

    The House sets aside its normal procedure to move quickly: no amendments, little debate, and a two-thirds bar instead of a simple majority. It is used for measures expected to be uncontroversial, so a bill that fails here failed despite broad expectations that it would not.
