Welcome to the California Building Standards Commission

Zero-Emission Vehicles (ZEV's)

The Governor’s Office of Planning and Research, in cooperation with numerous state agencies and stakeholders across California, has created several resources to help achieve the goals of Governor Brown’s Executive Order B-16-2012, which directs state government to meet a series of milestones toward a long-term target of 1.5 million ZEVs on California’s roadways by 2025.  Among these resources is the Zero-Emission Vehicles in California: Community Readiness Guidebook (PDF).  To access the Guidebook and other ZEV resources online, visit the OPR website.
