In 2012, the California Air Resources Board (CARB) established the Advanced Clean Cars Program (ACC) that 1) sets strong emission standards for new-light duty vehicles through MY 2025, and 2) requires manufacturers to sell an increasing number of zero-emissions vehicles (ZEV) each model year. Recently, CARB has proposed an updated rule to set a new, more stringent standard, for the sale of light-duty passenger vehicles beginning in 2026, leading up to a 100% new zero-emission vehicle sales requirement in 2035.
Currently, cars and trucks are the number one source of dangerous air pollutants in California. Additionally, transportation accounts for 29% greenhouse gas emissions in the United States. Light-duty vehicles account for 58% of these emissions. As the largest light duty market in the U.S. (12%), California must continue to be a national and global clean transportation leader, and push for the highest percentage of EV sales possible.
