Methods for Assessing Technology and Market Readiness for Clean Commercial Transportation

Each year, CALSTART and the California Air Resources Board (CARB) conduct technology status and market readiness snapshot assessments to analyze the technology and market progress of medium- and heavy-duty zero-emission (ZE) and ZE-enabling vehicles and equipment. This report explains the methods and process used to create and update these assessments, which depict a comprehensive view of clean commercial vehicle and equipment platform performance and readiness for the marketplace. This report will be updated on a periodic basis in support of the publication of CARB’s Appendix D: Long-Term Heavy-Duty Investment Strategy.

A previous version of this report was published in March 2022.
