In October 2025, Governor Newsom signed Assembly Bill 30, allowing E15 to be sold in California while CARB finalized the rules adopted today. E15 was the subject of a detailed scientific evaluation to ensure its use will not result in adverse impacts on public health or the environment. The assessment found E15’s impacts to be comparable to E10, with a potential for slight improvement in air quality. Overall, the evaluation determined that the primary health and environmental concerns associated with the gasoline blend come from petroleum portion of the fuel.

What Californians Should Know

• E15 will continue to be authorized for sale in California at gas stations. State law requires dispensers to be clearly labeled, and consumers should consult their owner’s manual to determine whether the fuel is compatible with their vehicle.
• Availability of E15 helps increase the number of choices consumers have at the pump and could help reduce gas prices.
• Ultimately fuel providers set the price of gasoline and decide which fuels to sell.
• The move supports expanding consumer fuel choices following Governor Newsom’s direction to prioritize the rulemaking.
