The Advanced Clean Fleet Regulation (ACF) is the California Air Resources Board’s overall strategy to accelerate a large-scale transition to zero-emissions medium- and heavy-duty vehicles. ACF works in conjunction with the Advanced Clean Trucks regulation, approved in 2021, which helps ensure zero-emission vehicles (ZEV) are available for sale. To help our stakeholders navigate this regulation, we’ve created a summary document that highlights the key components of the ACF.
