Overview

• Assembly Bill 30 permits retailers to sell gasoline with 15% ethanol immediately while the California Air Resources Board completes its air-quality compliance assessment.
• A UC Berkeley and U.S. Naval Academy study estimates potential savings of up to 20 cents per gallon, or roughly $2.7 billion annually statewide, contingent on station upgrades.
• UC Riverside research cited by the state indicates no increase in NOx emissions from higher ethanol blending and a reduction in particulate emissions.
• E15 is already available at more than 3,000 stations across 31 states, according to the governor’s office.
• State officials frame AB 30 as part of broader efforts launched after 2022 price spikes, including refinery transparency rules and ongoing CEC work on minimum inventory and resupply planning.
