This bill reauthorizes the diesel emissions reduction program. It amends the Energy Policy Act of 2005 to extend the program's authorization of appropriations, which had run through fiscal year 2024, through fiscal year 2029. The bill does not change how the program works, only how long it is authorized to receive funding. The House passed it on September 15, 2026, 343 to 79.
Each stop is a step the bill’s own record states, with the date it happened. A ring is a step not yet taken. A bill becomes law when the President signs it or Congress overrides a veto.
At least 14 organizations named this measure in a lobbying filing. A floor, not a total: they were counted by the client name on 57 quarterly reports filed by 5 lobbying firms and by 8 organizations lobbying for themselves in 2025 Q1, 2025 Q2, 2025 Q3, 2025 Q4, 2026 Q1, 2026 Q2 and 2026 Q3. An organization that lobbied this measure without naming it is not counted here.
33 of those filings did not cite this bill by number. They named a short title it shares with its Senate companion, S 2235, so the reference belongs to the pair rather than to one chamber’s vehicle.
The filings record that lobbying was reported on the measure. The form has no per-bill dollar figure and no field for a position, so nothing here says how much was spent or which side an organization took.
5 of them, in no ranking: South Coast Air Quality Management District; Mojave Desert Air Quality Management District; San Joaquin Valley Air Pollution Control District; Cummins Inc; Engine Manufacturers Association. Listed as filed, in the order the filings were read, and 9 others are not shown. These are not the largest, the earliest or the most active: we keep five names per measure, and the filings give no ranking.
From the LD-2 quarterly lobbying filings published at lda.gov by the Senate Office of Public Records. Read for 2025 Q1, 2025 Q2, 2025 Q3, 2025 Q4, 2026 Q1, 2026 Q2 and 2026 Q3. Our copy holds 24 fewer filings for 2025 Q1, 39 fewer filings for 2025 Q2, 42 fewer filings for 2025 Q3, 33 fewer filings for 2025 Q4, 28 fewer filings for 2026 Q1, 48 fewer filings for 2026 Q2 and 218 fewer filings for 2026 Q3 than the Senate's register counts, so those quarters are the filings we could read rather than every one filed. 2026 Q4 is still inside its filing window, so that quarter is only the filings posted so far.
