2017 Midterm Review Report
When CARB adopted the Advanced Clean Cars (ACC) program in 2012, the Agency committed to conduct a comprehensive review of three elements of the program - the zero-emission vehicle (ZEV) regulation, the 1 milligram per mile (mg/mi) particulate matter (PM) standard, and the light-duty vehicle greenhouse gas standards for 2022 and later model years.
The Board affirmed Staff’s recommendations at its March 2017 Board Hearing in Riverside, California.
A midterm evaluation of the light-duty vehicle greenhouse gas standards for 2022 through 2025 model years was also conducted at the national level and CARB staff collaborated with the U. S. Environmental Protection Agency (U.S. EPA) and the National Highway Traffic Safety Administration (NHTSA) to review the standards since the California program closely mirrors the national program for these model years.
