Advanced Clean Cars II

In late August, the California Air Resources Board approved a set of regulations dubbed “Advanced Clean Cars II (ACCII).” ACCII codifies the objectives set forth in Governor Gavin Newsom’s Executive Order N-79-20, which, inter alia, requires all new passenger vehicles sold in California to be zero emissions by 2035. Governor Newsom’s order garnered considerable media and political attention in the US.

ACCII, which applies only to automakers and covers only new vehicle sales, includes multiple modifications to the existing framework. First, ACCII accelerates requirements that automakers deliver an increasing number of zero-emission vehicles (including plug-in hybrid, full battery-electric and hydrogen fuel cell vehicles) each year beginning in model year 2026. Second, ACCII includes more stringent regulations for gasoline cars and heavier passenger trucks. To support these changes – and significantly, to offset the higher upfront cost of electric vehicles – the state is offering several incentive programs to consumers, including rebates and “clean fuel rewards.”

Notably, many other states emulate California’s policies regarding automotive emissions: to date, seventeen states have adopted all or part of California’s low-emission and zero-emission vehicle regulations. Additionally, the market for zero-emissions vehicles in California is already substantial; California’s sales of electric vehicles currently account for almost forty percent of US sales, making the California regulatory regime material to the industry.
