California operates the longest-standing and largest Low Carbon Fuel Standard (LCFS) program in North America. The program works to lower the Carbon Intensity (CI) of transportation fuels - the state’s largest source of greenhouse gas emissions. Effectively launched in 2015, the program has undergone multiple amendments, including measures to strengthen and extend the CI reduction targets, culminating in a 90% reduction goal by 2045. California also set a precedent of including a wide range of fuel types and transportation types in its LCFS program.
The LCFS program saw an initial rise in LCFS credit values in early years, followed by a sharp decline, driven by an overwhelming supply of credits from biofuels, ethanol and renewable diesel. Meanwhile, electricity has steadily increased its share of the state’s clean fuel supply. The 2025 amendments to the LCFS program took steps to improve the accuracy of CI scores for biofuels and introduced an automated mechanism to better balance credit supply and demand. These changes are designed to gradually reduce the credit surplus and restore stronger LCFS credit prices.
Annual starting in 2027 for 2026 compliance year.

Learn moreThe LCFS program establishes Carbon Intensity (CI) standards for gasoline and diesel fuel produced or imported in the state. Fuel suppliers (typically oil and gas companies) that exceed the CI standard may stay in compliance by purchasing credits that are issued to parties (like electric vehicle charger companies or biofuel producers) that supply fuel with a CI that is lower than the standard. Each year, the CI standard decreases in order to continue to support the market structure (i.e. driving demand for credits) and move towards the program goals of a lower carbon fuel system.
