CARB is scheduled to consider proposed amendments allowing the continued voluntary sale of E15 gasoline at its September 24-25, 2026 Board meeting, following a public comment period that remains open through September 14, 2026.

The proposal would establish a fuel specification for E15 gasoline within the California Reformulated Gasoline Regulations (CaRFG) and clarify the standards under which fuel suppliers may continue to offer both E10 and E15 fuel blends in California.

The rulemaking implements AB 30 (Alvarez, Chapter 247, Statutes of 2025), which was signed by Governor Newsom on October 2, 2025, and championed by the California Problem Solvers Caucus. The legislation authorized the sale of E15 until CARB either adopts a permanent E15 fuel specification or determines that such a standard cannot be established without adverse impacts on public health or the environment.

You can review the regulatory package for more information or the AB 30 FAQ website. Additional information will be posted by CARB as the September hearing date approaches.
