California ZEV Population Dashboard
The California Air Resources Board (CARB) and other local, state, and federal partners have invested heavily in the deployment of zero-emission trucks and buses to meet California’s health-based air quality standards and greenhouse gas reduction goals.
For the first time, data from several medium and heavy-duty (MHD) zero-emission vehicle (ZEV) deployments has been compiled into a single dashboard alongside results from the first few years of the Advanced Clean Trucks (ACT) regulation. The California Zero-Emission Vehicle Population Dashboard tracks when and where MHD ZEVs are deployed in California and, if applicable, how much funding was provided to help put them on the road.
Watch our intro video to see how you can quickly use this tool to gather insights about MHD ZEV deployments in California.
A key feature of the dashboard is providing information over multiple geographic layers including Air District, County, State Assembly District, State Senate District, and Disadvantaged Community Status. This initial iteration of the dashboard includes deployed medium-duty and heavy-duty zero-emission vehicles, such as trucks and buses, and in the future will be expanded to include off-road vehicles, light‑duty vehicles, and vehicles supported by other funding or regulatory programs.
