The Health and Safety Code directed the Board, no later than January 1, 1992, to take whatever actions are necessary, cost-effective and technologically feasible in order to achieve by December 31, 2000, a reduction in reactive organic gases of at least 55 percent and at least a 15 percent reduction in the emissions of oxides of nitrogen from motor vehicles, and the maximum feasible reductions in particulate matter, carbon monoxide, and toxic air contaminants from vehicular sources.

The ARB's fuels effort is made up of several components which broadly fall into two categories: (1) adopting and enforcing fuel specifications, and (2) controlling emissions from marketing and distributing fuels in California. The ARB also has developed a wide variety of general information about California refineries. For example, the ARB has compiled information on California refinery emergency response and outreach programs and has developed an assessment of refineries emissions related to the production of CaRFG2. ARB staff has also completed an assessment of air district civil penalties for violations air pollution control regulations at refineries, as well as, provided other information and links on California refineries.

Executive Order S-1-07, the Low Carbon Fuel Standard (LCFS) (issued on January 18, 2007), calls for a reduction of at least 10 percent in the carbon intensity of California's transportation fuels by 2020. It instructed the California Environmental Protection Agency to coordinate activities between the University of California, the California Energy Commission and other state agencies to develop and propose a draft compliance schedule to meet the 2020 target. Furthermore, it directed ARB to consider initiating a regulatory proceedings to establish and implement the LCFS. In response, ARB identified the LCFS as an early action item with a regulation to be adopted and implemented by 2010.

The ARB also adopts standards for vehicular liquefied petroleum gas and other alternative fuels sold commercially in California (CNG, LNG, Biodiesel, Renewable Diesel, E85) for motor vehicle use and for fuel used in certification testing of new motor vehicles
