An Act relative to the sale of zero-emission vehicles

Maddy summaryThis bill requires Massachusetts' Department of Environmental Protection to annually review manufacturers' compliance with California's Advanced Clean Cars II Rule starting in 2025. It allows the department to delay zero-emission vehicle (ZEV) sales requirements for a model year if either (1) manufacturers collectively selling 70%+ of vehicles fail to meet annual ZEV goals, or (2) sufficient public charging infrastructure isn't available statewide. The bill also mandates that all new Commonwealth purchases of medium- and heavy-duty trucks must be zero-emission starting July 2025, with full fleet conversion by 2035, while permitting exceptions for trucks that don't meet operational needs or charging requirements. Additionally, it delays implementation of California's Advanced Clean Trucks regulations until July 2029.
