Zero Emission Truck Deployments Surged 37% in 2025

Zero-emission truck deployments in the United States experienced a significant surge of 37% in 2025, according to CALSTART's "Zeroing in on Zero-Emission Trucks" report. While the first half of the year saw a slower uptake, the latter half witnessed a substantial acceleration, leading to zero-emission trucks comprising 4.14% of all new truck deployments by the end of 2025. This marks a considerable increase from previous periods, indicating growing momentum in the adoption of cleaner freight transportation solutions.

The report highlights that this growth was driven by increased availability of vehicles and expanding charging infrastructure. Specific data points from the report indicate that the number of zero-emission trucks on the road more than doubled compared to 2024 figures. Key manufacturers like Tesla, BYD, and Freightliner have been instrumental in supplying a wider range of electric truck models, from light-duty vans to heavy-duty tractors. The expansion of public and private charging networks, supported by government incentives and private investment, has also played a crucial role in alleviating range anxiety and facilitating daily operations for fleet managers.

CALSTART's analysis further breaks down the deployment figures by truck class and region. Medium-duty electric trucks saw the most significant percentage increase, driven by last-mile delivery services in urban areas. Heavy-duty electric trucks, while still representing a smaller fraction of the total, also showed robust growth, particularly in regions with supportive policies and dedicated charging hubs. The report attributes this trend to a combination of regulatory pressures, corporate sustainability goals, and the increasing economic viability of electric powertrains due to lower operating and maintenance costs compared to their diesel counterparts. The total number of zero-emission trucks deployed across the US in 2025 reached over 15,000 units, a substantial leap from the approximately 11,000 units deployed in 2024.
