The 'Low or No Emission' Bus Program Spent $2 Billion in FY2025. 97% of the Awards Went to Buses That Still Burn Fuel.

The Federal Transit Administration's Low or No Emission program has funded bus purchases since 2016 with one stated purpose: move transit fleets off fossil fuel.▸ The claim built into the program's own name is that the money buys zero-emission — or at worst, low-emission — buses. Test that claim against the FY2025 award list and the "no emission" half mostly vanishes. Meanwhile, a second, quieter number complicates even the buses that qualify: the people who fix them are leaving the trade faster than anyone is training replacements.

On November 20, 2025, FTA announced what it called its largest-ever round of bus funding.▸ A Federal Register notice published January 15, 2026 put the exact figure at $2,027,948,082 for 165 projects across 45 states and Washington, D.C. — split between $1,630,282,606 for 103 Low or No Emission (Low-No) projects and $397,665,476 for 62 projects under the separate Grants for Buses and Bus Facilities Competitive Program.

The Low-No program is the older and larger of the two, created under the 2015 FAST Act specifically — per its own statutory language — to help transit agencies deploy "the lowest and zero-emission vehicles."▸ That's where the claim gets tested. Transportation for America's independent review of the more than 100 Low-No projects FTA selected found "an unprecedented 97 percent of awards made by USDOT in the FY25 funding opportunity went to low-emission buses" — compressed natural gas, propane, and diesel-electric hybrids — rather than the battery-electric or hydrogen fuel-cell buses that qualify as zero-emission. The organization, which has tracked the program since 2016, called it "a drastic departure" from prior years, including the first Trump administration, and concluded that "a program created nearly ten years ago specifically to prioritize the deployment of zero-emission buses is going to buy almost none of them." FTA's own Federal Register notice does not break the $2.03 billion down by vehicle technology, so the 97% figure is T4America's count of individual award announcements, not a government-published statistic — the clearest way to read it is as an outside audit of a public list, not a disputed one.

Even the buses that do qualify as zero- or low-emission need someone to keep them running, and that workforce is not expanding to meet a $2 billion funding wave.▸ The Bureau of Labor Statistics' Occupational Outlook Handbook counted 319,900 diesel service technicians and mechanics nationally in 2024 — the occupational category that covers bus, truck, and other diesel-engine repair work, transit and non-transit alike — and projects employment will grow just 2% by 2034, "slower than average." Despite that near-flat growth, BLS still expects about 26,500 openings a year, on average, over the decade, because "most of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire."

Run BLS's own two published numbers against each other: 26,500 average annual openings against a decade-long net employment gain of just 7,800 workers (2% of the 2024 base) means roughly 780 of those openings a year come from growth — call it 800.▸ The remaining ~25,700 openings a year, on this math, come from workers retiring or transferring out, not from agencies adding capacity. Separately, the American Public Transportation Association's most recent workforce survey — cited in TransitCenter's May 2024 workforce report — found a 13% vacancy rate for bus mechanics across responding agencies, regardless of agency size, second only to bus operator as the hardest position in the industry to fill. New federal money for buses does not, by itself, hire or train the technicians the resulting fleet will need — electric buses in particular carry high-voltage systems that few diesel-trained mechanics are yet certified to touch, per the same TransitCenter report.

The BLS mechanic figures describe the broader "diesel service technicians and mechanics" occupation (SOC 49-3031), which BLS does not break out by transit vs. non-transit employer; the 97% low-emission figure is Transportation for America's independent count of FTA's published award list, not a government-issued statistic, since FTA's own notice does not report funding by vehicle emission type.
