Abstract
California has set some of the most ambitious clean-truck goals in the world. Governor Newsom’s 2020 Executive Order includes a goal that all medium- and heavy-duty trucks be zero-emission by 2045 where feasible. To meet this goal, the California Air Resources Board approved two regulations focusing on trucks—the Advanced Clean Trucks rule, requiring manufacturers to sell zero emission trucks (ZETs), and the Advanced Clean Fleets rule, requiring fleets to purchase them. Rapidly shifting truck purchases toward ZETs requires many concurrent changes—fleets must want to buy these vehicles, manufacturers must provide them, and (with state assistance) their sale prices must be affordable. Success also depends on the timely build-out of charging and hydrogen refueling infrastructure. All of this requires careful planning and tracking of progress. To support this effort, a wide range of data and indicators are needed to track progress and indicate where more effort may be needed. To this end, the research team developed a framework of key performance indicators and a strategy for a statewide database—preferably with public access—that would allow policymakers, fleets, and utilities to monitor progress and identify gaps.
