Greenhouse Gases

The passage of AB 32, the California Global Warming Solutions Act of 2006, requires a significant reduction of greenhouse gas (GHG) emissions in the state of California.  AB 32 was the first program in the country to take a comprehensive, long-term approach to address climate change.  Three major components of AB 32 include:


  • Cap and Trade Program (and the Mandatory Reporting Regulation (MRR))

  • Low Carbon Fuel Standard (LCFS)

  • Advanced Clean Cars Program

Ashworth Leininger Group (ALG) collaborates with our clients and agency staffs to design, quantify, and implement GHG mitigation programs required to secure pre-construction approvals or CEQA certification. Here our staff leverages technical expertise and direct prior experience in identifying cost-effective and practical GHG reduction options for industrial operations. We also assist our clients and equipment engineers in the integration of GHG reduction technologies into project design, which realizes economic and thermal efficiencies and decreases overall project costs.

Low Carbon Fuel Standard (LCFS)

As with AB32, the CARB Low Carbon Fuel Standard Regulation (LCFS), found in sections 95480 to 95503 of title 17, California Code of Regulations, requires independent verification of data reports specified in section 95500.   ALG is among the first of CARB's accredited verification bodies for the LCFS program, with four approved lead verifiers. 


Entities specified in section 95500 are required to retain the services of independent verifiers accredited by CARB, beginning with 2020 fuel pathway applications and LCFS data reports. Only CARB-accredited verification bodies may provide LCFS verification services.

While, the Low Carbon Fuel Standard (LCFS) verification program is relatively new to industry; ALG already has considerable experience in this program having assisted multiple petroleum clients evaluate and permit Alternative Fuels projects, as well as submit Refinery Investment Credit applications to CARB. ALG is accredited as a Verification Body in the LCFS program, and is one of the few approved to conduct verification services for all types of reports (Fuel Pathway, Quarterly Fuel Transactions, Petroleum-Based Fuel Reports, and Carbon Capture and Sequestration). This, coupled with our longstanding experience with the AB32 MRR reporting and verification program, enable ALG to provide expert, efficient, and cost-effective consulting to the clients we serve.
