Zeroing In on CALSTART’s 2025 ZET Report

Despite recent news on the regulatory landscape about CARB’s withdrawal request of ACF Fleet Electrification waiver, the data is showing that momentum is not slowing down in the Zero-emission Truck (ZET) market as states, manufacturers, and fleets are continuing deployments to achieve sustainability goals, reduce environmental impact, and capitalize on significant financial savings.

Zero-emission vehicle

CALSTART’s latest Zeroing in on Zero-Emission Trucks market update provides a comprehensive snapshot of deployment trends, tracking the rapid expansion of ZETs across the U.S. medium- and heavy-duty truck market. Covering Class 2b through Class 8 vehicles — including cargo vans, step vans, refuse trucks, and yard tractors—the report highlights how and where the shift toward cleaner transportation solutions are occurring.

The sixth edition of this report offers deeper insights into key market trends, adoption rates, and emerging opportunities through June 2024. This update illustrates how industry participation is growing, deployments are starting to scale, and zero-emission technology is becoming a mainstream solution for commercial transportation.

 

ZET report key findings:

  • Cumulatively, more than 42,500 ZETs are in operation nationwide. A 41% increase over the 2023 figure, but accomplished in just the first 6 months of the year.
  • Over 12,500 new ZETs were deployed in the first half of 2024, with 88% of the growth in the cargo van space highlighting the strong operational savings being achieved.
  • Sixteen states now exceed 1,000 ZET deployments, compared to just six in the previous update with California, Texas, Florida and New York leading the way.
  • Washington and Colorado are one of the fastest markets, which is being driven by the availability of state-level and utility offered vehicle and infrastructure incentives.
  • 37 manufacturers have deployed ZETs, up from 32, reflecting broader industry participation.

Where fleets have found economic success in electrification:

  • Take a full project lifecycle view: Partner to co-develop electrification projects, from the initial planning to asset management.
  • Focus on Class 2B-4 fleets: There is a reason why almost 90% of the EVs deployed this year are in the 2 – 4 class range: Proven technology backed by tier 1 OEMs at a comparable cost to the ICE equivalent; high correlation of range to routes; enhanced operations with onsite or depot charging to optimize energy/fuel costs.
  • Leverage available funding: With reduced federal incentives available, leverage in-state utility make-ready programs to reduce installation costs by up to 80%.

The transition to zero-emission vehicles is proving to be a smart financial decision for fleets. With significantly lower fuel costs, reduced maintenance needs, and access to incentives, electric vehicles can deliver substantial long-term savings. Fleets that make the switch are seeing lower total cost of ownership (TCO), fewer unplanned repairs, and increased operational efficiency — all while meeting sustainability goals and future-proofing their operations against unpredictable fuel prices.
