Inception of the Low Carbon Fuel Standard Program

This page last reviewed December 11, 2015

This page provides information regarding the inception of ARB's Low Carbon Fuel Standard Program prior to 2010 pursuant to the California Assembly Bill AB 32 and the Governor's Executive Order S-01-07.

Executive Order S-1-07, the Low Carbon Fuel Standard (LCFS) (issued on January 18, 2007), calls for a reduction of at least 10 percent in the carbon intensity of California's transportation fuels by 2020. It instructed the California Environmental Protection Agency to coordinate activities between the University of California, the California Energy Commission and other state agencies to develop and propose a draft compliance schedule to meet the 2020 target. Furthermore, it directed ARB to consider initiating a regulatory proceedings to establish and implement the LCFS. In response, ARB approved the LCFS in 2009 and implemented in 2010 as a discrete early action measure under AB 32 with requirements to reduce the carbon intensity (CI) of gasoline and diesel fuels by at least 10 percent by 2020 with a 2010 baseline. In addition, ARB subsequently approved amendments to the LCFS in December 2011, which began implementation on January 1, 2013. As the result of a court ruling that found procedural issues related to the original adoption of the LCFS, ARB re-adopted the LCFS regulation in September 2015, and the changes went into effect on January 1, 2016. The program establishes a strong framework to promote the low carbon fuel adoption necessary to achieve the Governor's 2030 and 2050 greenhouse gas goals.
