Vehicle emissions hurt public health, welfare, the environment, and the climate in multiple ways. The Advanced Clean Cars (ACC) Regulation is one of CARB’s most effective programs for addressing vehicle emission harms. It significantly reduces soot, smog-forming pollutants, toxics, and greenhouse gases through coordinated requirements for passenger cars and light trucks.

In 2017, CARB reviewed the effectiveness of the original ACC Regulation and the progress of vehicle manufacturers in meeting its requirements. The conclusion: the standards are feasible and staff should propose strengthened requirements for 2026 and subsequent model years. 

The proposed ACC II Regulation will further reduce harmful vehicle pollution. The new Low-Emission Vehicle (LEV) IV requirements will reduce exhaust and evaporative emissions under a wider range of real-world conditions. The new Zero-Emission Vehicle (ZEV) Regulation requirements will transition all new light-duty vehicle sales in California to zero-emission by 2035 and protect the emission benefits of the program by ensuring these vehicles will meet consumers’ transportation needs. 

ACC II is critical to meeting California’s public health and climate goals and meeting State and federal air quality standards. It will also save lives, reduce hospital admissions and emergency room visits, and provide these benefits more equitably.

In addition to the proposed regulations, the Board will also consider the Draft Environmental Analysis of ACC II.

Inquiries concerning the substance of the proposed regulatory action may be directed to the agency representative Anna Wong, Manager, ZEV Market Advancement Section, at (279) 208-7203 or (designated back-up contact) Shobna Sahni, Chief, New Vehicle/Engines Program Branch, at (951) 542-3369.
