In an effort to curb GHG emissions from its transportation sector, California regulators implemented the Low Carbon Fuel Standard (LCFS) in January 2011. The LCFS sets annual carbon intensity (CI) benchmarks on transportation fuels with the intent to incentivize the utilization of low-carbon, cleaner fuels to decarbonize the state’s highest emitting sector. The CI benchmark decreases annually in order to reach the goal of a 20% reduction by 2030 (with a current rate of -11.25% for 2023). In less than a decade from its initial implementation, the LCFS has been responsible for a 77.5 Mt GHG reduction. As state regulators plan to increase the program’s 2030 reduction target, the LCFS will continue to play a central role in helping achieve the state’s decarbonization targets. The transition to cleaner fuels and the subsequent reduction in emissions will also have significant impacts on the demand for and prices of allowances in the state’s cap-and-trade program.
