Zero-Emission Trucks Represented Over 4 Percent of New Truck Deployments in the Second Half of 2025

After a slower first half of 2025, zero-emission truck (ZET) deployment in the United States gained momentum in the second half of the year, with ZETs representing 4.14 percent of all truck deployments from July through December 2025, up from 1.32 percent in the first half of the year, according to the June 2026 edition of CALSTART’s biannual Zeroing in on ZETs report.

“The market, even absent tax credits, has shown positive growth. The data points to a strong zero-emission future as operational cost advantages continue to accelerate over fossil fuels, capital costs continue declining, and operator acceptance trends in a positive direction. This report continues to play a vital role in mapping the trajectory and consequences of ZET adoption across the country,” said Jared Schnader, Executive Vice President of Initiatives in CALSTART’s Florida Regional Office.
