View the workshop recording

The California Air Resources Board (CARB or the Board) staff held a public workshop to gather input on the development of the Advanced Clean Cars II (ACC II) regulations. The 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.

Building on the September 2020 workshop, staff presented updated analyses and proposals to amend the Low Emission Vehicle (or LEV IV) Regulation to reduce criteria pollutant emissions and preliminary proposals to amend the ZEV Regulation. Staff also presented updates on projections of costs for future ZEV technologies and proposed measures to ensure ZEV durability and serviceability.

This public workshop was held on GoToWebinar, and the workshop recording is now available. 

Date: Thursday, May 6, 2021
Time: 9:00 a.m. – 1:00 p.m. (PDT)
Location: GoToWebinar 

Staff request stakeholder comments following the workshop be submitted to cleancars@arb.ca.gov by June 11, 2021.

Background

In 2012, CARB adopted a set of regulations to control emissions from passenger vehicles, collectively called Advanced Clean Cars (ACC). Advanced Clean Cars combined the control of smog-causing (criteria) pollutants and greenhouse gas (GHG) emissions into a single coordinated package of regulations through 2025 model year vehicles: the Low-Emission Vehicle III regulation for criteria (LEV III Criteria) and GHG (LEV III GHG) emissions, and a technology forcing Zero Emission Vehicle (ZEV) Regulation.

A California midterm review of the standards was presented to the Board in March 2017. At that time, the Board also directed staff to begin working on post-2025 model year vehicle regulations. Since the midterm review, staff have continued to research additional measures to reduce air pollution from light-duty and medium-duty vehicles. Additionally, in September 2020, Governor Newsom signed Executive Order N-79-20 which established a goal that 100 percent of California sales of new passenger car and trucks be zero-emission by 2035 and directed CARB to develop and propose regulations toward this goal. Furthermore, CARB’s 2020 Mobile Source Strategy illustrates that an aggressive deployment of ZEVs will be needed for the State to meet federal air quality requirements and the State’s climate change targets.
