Source: International Energy Agency
Last updated: 05 September 2025
Executive order directs state to require that, by 2035, all new light-duty vehicles sold in California be zero-emission vehicles, and establish tougher tailpipe emissions standards for the remaining internal combustion engines in the state beyond that date. The regulations require manufacturers to offer rising percentages of ZEVs in their fleets between 2026 and 2035. Such vehicles must make up 35pc of those offered in the 2026 model year, 68pc of vehicles offered in 2030 and 100pc of new vehicles for the 2035 model year.
