The Advanced Clean Cars II (ACC II) regulations will seek to reduce criteria and greenhouse gas emissions from new light- and medium-duty vehicles beyond the 2025 model year and increase the number of zero-emission vehicles (ZEVs) for sale.
The following draft ACC II regulation language is available at the Advanced Clean Cars Meetings and Workshop webpage:
- Draft Evaporative Emission Standards and Test Procedures
- Draft Exhaust Emission Standards and Test Procedures
- Draft Electric Vehicle Charging Requirements
- Draft California Refueling Emission Standards and Test Procedures
- Draft Zero-Emission Vehicle Battery Labeling Requirements
- Draft In-Use Compliance, Corrective Action and Recall Protocols for Zero-Emission Vehicles
- Draft Warranty Requirements for Zero-Emission Vehicles and for Batteries in Plug-in Hybrid Electric Vehicles
- Draft Service Information Requirements
- Draft Zero-Emission Vehicle Standards for 2026 and Subsequent Model Year Passenger Cars and Light-Duty Trucks
CARB staff continue to engage with stakeholders on the development of the ACC II regulations, and anticipate the regulatory language and proposal will change for the final staff proposal.
