Advanced Clean Cars II Program

Advanced Clean Cars II Program

The Advanced Clean Cars I Program was first adopted by CARB in 2012, including the Low-Emission Vehicle (LEV) III Criteria Regulation, the LEV III Greenhouse Gas Regulation, and the Zero-Emission Vehicle (ZEV) Regulation. Following the Board’s direction to begin development of standards for model years after 2025, the Advanced Clean Cars II (ACC II) rulemaking is currently in process to establish the next set of low-emission vehicle and zero-emission vehicle requirements to further reduce emissions of criteria air pollutants and precursors and greenhouse gases from light and medium-duty vehicles in California. Accordingly, the proposed ACC II Program would include more stringent emission standards and requirements for passenger vehicle manufacturers to increase the proportion of zero emission vehicles (ZEVs) offered for sale in California (e.g., hydrogen fuel cell electric vehicles, battery electric vehicles, and plug-in hybrid electric vehicles). The main objective of the ACC II Program is to maximize criteria emission benefits from internal combustion engine vehicles, while accelerating the transition to ZEVs through both increased stringency of requirements and associated actions to support wide-scale ZEV adoption and use. The targets of Governor Newsom’s Executive Order N-79-20 calling for all new in-state sales of passenger cars and trucks to be zero emission by 2035 is a key consideration of the ACC II Program. Under the ACC II Program, LEV IV will aim to reduce emissions by tightening standards where necessary Advanced Clean Cars II Program and pursuing additional requirements that will translate to real-world emission benefits, such as ensuring that cold-start emissions are well-controlled, revising medium-duty vehicle standards to cover a broader range of in-use driving conditions, and strengthening emission standards for aggressive driving. The ZEV Regulation will increase the new vehicle sales requirements to 100% plug-in hybrid electric vehicles and ZEVs by 2035 in California. Additionally, the ACC II Program will aim to ensure that ZEVs are full replacement vehicles for all drivers, for both new and used markets, by adding ZEV assurance measures, such as requiring a consumer-facing battery state of health indicator, adding ZEVs into existing service information requirements, and adding useful life and minimum warranty requirements for ZEVs. The project is the collective set of proposed regulatory amendments to the Low- Emission Vehicle and Zero-Emission Vehicle Regulations that would affect manufacturer production and design of vehicles. The amendments to these regulations are analyzed as one project because the regulations are related and compliance responses by vehicle manufacturers would have a combined effect on the statewide vehicle fleet, the ways light- and medium-duty vehicles are sold and leased, and the use of alternative fuels. The project collective is necessary to provide a comprehensive review of the combined, or cumulative, effect of these regulatory amendments.
