The California Natural Gas Vehicle Partnership (CNGVP) is an alliance of air quality, transportation and energy agencies, vehicle and engine manufacturers, fuel providers, transit and refuse hauler associations, and other stakeholders interested in increasing and strengthening the deployment of low-emission natural gas vehicles throughout California. CNGVP promotes research, development, demonstration, deployment, accessibility, commercialization, and legislative support across California. The success of these efforts in California has served as a model for low-emission, alternative fuel initiatives in other states across the country and around the globe.
