LCFS Workgroups and Subprograms

This page last reviewed November 25, 2014


The Low Carbon Fuel Standard regulation was approved by the Board on April 23, 2009 and became law on January 12, 2010.  The Resolutuion 09-31 directed the ARB staff to establish several workgroups to address the issues that raised by the stakeholders during the rulemaking process.

LCFS Expert Workgroup (EWG)

To address the indirect land use change (iLUC) of the biofuels.  The first meeting was held on February 26, 2010 and monthly thereafter to identify the subjects and workplans. For more information, see the EWG website

LCFS Program Review Advisory Panel

Created to assist staff in assessing the efficacy of LCFS Program implementation.  For more information, see the Advisory Panel website.

LCFS Reporting Tool Workgroup (LRT)

Development of the Compliance Tools and Enforcement Protocol for the LCFS such as tracking, certification, and enforcement of fuels and fuel feedstock of LCFS.  For more more information see the LRT website.

LCFS Sustainability Workgroup (SWG)

The Board directed staff to work with stakeholders to develop sustainability provisions for the LCFS and bring recommendations back to the Board by December 2011. For more information see the SWG website.

LCFS Electricity Workgroup

The Electricity Workgroup was created to address issues related to regulated parties of electricity as a transportation fuel. The Board directed staff at the April 2009 hearing to form the workgroup with stakeholders and continue to work to review applicable provisions. For more information see the Electricity Workgroup meeting website.

    LCFS Crude Oil Lifecycle Assessment

    This page provides information regarding the Crude Oil Lifecycle Assessment under the LCFS.  In 2009, the Board directed staff to prepare guidelines to assist regulated parties in determining carbon intensity values for crude oil used in California.  For more information see the LCFS Crude Oil Lifecycle Assesment website.

      Lifecycle Analysis Workgroup (LCA)

      Investigation of the lifecycle of Energy Use and Greenhouse Gases of available transportation fuel pathways (so called Well-to-Wheel or WTW) including Sustainability, Land Use Conversion, Fuel Co-products, Default Values, Uncertainty, etc.)
