Nationwide Impacts Of California’s Advanced Clean Cars II Rule

The Clean Air Act allows California to adopt stronger pollution standards than the federal government and for other states to follow suit. California recently adopted its Advanced Clean Cars II (ACC II) rule, setting a 100 percent zero-emission vehicle (ZEV) sales standard by 2035. New research uses the Energy Policy Simulator to assess the impact of additional state adoption of ACC II accounting for Inflation Reduction Act tax credits, finding adoption by California and 16 other states would accelerate electric vehicle adoption, cut 1.3 gigatons of carbon emissions (equivalent to closing 13 coal plants), create 300,000 new jobs, save households $230 per year, and prevent 5,000 deaths in 2050.
