vehicle emission standards; energy source

HB 2535 would require Arizona to adopt vehicle emission standards identical to California's for model year 2028 and newer vehicles, but only for standards California has received federal approval for. This directly affects automakers selling new vehicles in Arizona and the Arizona Department of Environmental Quality, which would implement the rules. The bill amends state law to align Arizona's standards with California's instead of federal requirements. The bill is currently in early legislative stages (House first/second reading) with no votes cast yet.
