Hydrogen Fueling Station Evaluation
The California Air Resources Board (CARB) may not enforce any element of regulations that would require a supplier to construct, operate, or provide funding to construct or operate a publicly available hydrogen fueling station.
Annually, CARB must aggregate and share the number of hydrogen vehicles that manufacturers project will be sold or leased over the next three years and the total number of hydrogen vehicle registered in the state. Based on this information, CARB must evaluate the need for additional publicly available hydrogen fueling stations for the subsequent three years and report findings to the California Energy Commission (CEC) including the of number of stations, geographic areas where stations are needed, and minimum operating standards, such as number of dispensers and filling pressures.
The CEC will allocate no less than 15% of the moneys appropriated by the Legislature from the Alternative and Renewable Fuel and Vehicle Technology Fund per year to fund the number of stations deemed necessary based on CARB’s evaluation and reports. The CEC may stop funding new stations if it determines, in consultation with CARB, that the private sector is developing publicly available stations without the need for government support.
The CEC and CARB must issue an annual report on progress toward establishing a hydrogen fueling station network that meets the needs of vehicles being used in the state. CARB may also design grants, incentives, loan programs, and other forms of financial assistance to assist in program implementation. For more information see CARB’s Hydrogen Fueling Infrastructure website and the CEC and CARB Joint Agency Report on Assembly Bill 8.
(Reference California Health and Safety Code 43018.9)
Hydrogen and Electric Vehicle (EV) Charger Local Permitting Policies
All cities and counties, including charter cities, must adopt an ordinance that creates an expedited and streamlined permitting process for EV chargers and hydrogen fueling stations. Cities and counties must approve applications to install EV chargers within five to ten business days, depending on the number of chargers proposed in the application. Applications will be approved after 20 to 40 business days, if the county or city does not approve the application, the building official does not deny the application, or the city or county does not submit an appeal. Each city or county must consult with the local fire department or district and the utility director to develop the ordinance, which must include a checklist of all requirements for EV chargers to be eligible for expedited review. A complete application that is consistent with the city or county ordinance must be approved, and entities submitting incomplete applications must be notified of the necessary required information to be granted expedited permit issuance. These provisions must be met by September 30, 2025, by cities and counties with populations above 250,000 residents. Cities and counties with populations less than 250,000 residents must meet these provisions by September 30, 2028.

For more information, see the ZEV Market Deployment Strategy website.
(Reference Executive Order N-79-20)
Low Carbon Fuel Standard
California’s Low Carbon Fuel Standard (LCFS) Program requires a reduction in the carbon intensity of transportation fuels that are sold, supplied, or offered for sale in the state through 2030. The California Air Resources Board regulations require transportation fuel producers and importers to meet specified average carbon intensity requirements for fuel. LCFS regulated fuels include natural gas, electricity, hydrogen, gasoline mixed with at least 10% corn-derived ethanol, biomass-based diesel, and propane. Non-biomass-based alternative fuels that are supplied in California for use in transportation at an aggregated volume of less than 3.6 million gasoline gallon equivalents per year are exempt from LCFS requirements. Other exemptions apply for transportation fuel used in specific applications. The LCFS Program allows producers and importers to generate, acquire, transfer, bank, borrow, and trade credits. Fuel producers and importers regulated under the LCFS must meet quarterly and annual reporting requirements. For more information, see the LCFS Program website.
(Reference California Code of Regulations Title 17, Section 95480-95490; and California Health and Safety Code 38500-38599)
Low Emission Vehicle (LEV) Standards
California’s LEV II exhaust emissions standards apply to Model Year (MY) 2004 and subsequent model year passenger cars, light-duty trucks, and medium-duty passenger vehicles meeting specified exhaust standards. The LEV II standards represent the maximum exhaust emissions for LEVs, Ultra LEVs, and Super Ultra LEVs, including flexible fuel, bi-fuel, and dual-fuel vehicles when operating on an alternative fuel. MY 2009 and subsequent model year passenger cars, light-duty trucks, and medium-duty passenger vehicles must meet specified fleet average greenhouse gas (GHG) exhaust emissions requirements. Each manufacturer must comply with these fleet average GHG requirements, which are based on California Air Resources Board (CARB) calculations. Bi-fuel, flexible fuel, dual-fuel, and grid-connected hybrid electric vehicles may be eligible for an alternative compliance method when operating on gasoline.
In December 2012, CARB finalized regulatory requirements, referred to as LEV III, which allow vehicle manufacturer compliance with the U.S. Environmental Protection Agency’s GHG requirements for MY 2017-2025 to serve as compliance with California’s adopted GHG emissions requirements for those same model years.
In November 2022, CARB approved LEV IV standards, which updates regulations for light- and medium-duty internal combustion engine vehicles by reducing allowable exhaust emissions and emissions caused by evaporation. LEV IV also changes the calculation procedure for new vehicle fleet-average emissions and prohibits zero emissions vehicles from being considered in fleet-average emissions calculations by MY 2029.
For more information, see the CARB LEV website for more information.
(Reference California Code of Regulations Title 13, Section 1961-1961.4)

In consultation with the State Energy Resources Conservation and Development Commission, CARB prepared a funding plan that includes a market and technology assessment, assessments of existing zero and near-zero emission funding programs, and programs that increase access to disadvantaged, low-income, and moderate-income communities and consumers. Potential programs under the initiative include those involving innovative financing, car sharing, charging infrastructure in multi-unit dwellings located in disadvantaged communities, public transit, and agricultural vanpool programs. The funding plan must be updated at least every three years through January 1, 2023.
(Reference California Health and Safety Code 44258.4)
Zero Emission Vehicle (ZEV) Production Requirements
The California Air Resources Board (CARB) certifies new passenger cars, light-duty trucks, and medium-duty passenger vehicles as ZEVs if the vehicles produce zero exhaust emissions of any criteria pollutant (or precursor pollutant) under all possible operational modes and conditions. Manufacturers with annual sales between 4,501 and 60,000 vehicles may comply with the ZEV requirements through multiple alternative compliance options that include producing low emission vehicles and obtaining ZEV credits. Manufacturers with annual sales of 4,500 vehicles or less are not subject to this regulation.
CARB’s emissions control program for model year (MY) 2017 through 2025 combines the control of smog, soot, and greenhouse gases (GHGs) and requirements for ZEVs into a single package of standards called Advanced Clean Cars (ACC). In December 2012, CARB finalized new regulatory requirements that allow vehicle manufacturer compliance with the U.S. Environmental Protection Agency’s (EPA) GHG requirements for MY 2017 through 2025 to serve as compliance with California’s adopted GHG emissions requirements for those same model years.
The accounting procedures for MY 2018 through 2025 are based on a credit system as shown in the table below. The minimum ZEV requirement for each manufacturer includes the percentage of passenger cars and light-duty trucks produced by the manufacturer and delivered for sale in California. The regulation also includes opportunities for compliance with transitional ZEVs, which must demonstrate certain exhaust emissions standards, evaporative emissions standards, on-board diagnostic requirements, and extended warranties.
| MY | ZEV Requirement |
|---|---|
| 2021 | 12% |
| 2022 | 14.5% |
| 2023 | 17% |
| 2024 | 19.5% |
| 2025 and later | 22% |
In November 2022, CARB finalized another rule in addition to the ACC emissions control program for MY 2026 through 2035 called Advanced Clean Cars II (ACCII), requiring an increasing percentage of ZEVs in new vehicle sales beyond MY 2025. ZEV sales requirements under ACCII are shown in the table below.
| MY | ZEV Requirement |
|---|---|
| 2026 | 35% |
| 2027 | 43% |
| 2028 | 51% |
| 2029 | 59% |
| 2030 | 68% |
| 20231 | 76% |
| 2032 | 82% |
| 2033 | 88% |
| 2034 | 94% |
