What is AB32?

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

Our Team

ALG’s team of verifiers are accredited in all sectors of reporting under EPA, California, and Oregon Green House Gas (GHG) and Low Carbon Fuel/Clean Fuels standards.

"Verification of GHGs is challenging endeavor especially with numerous diverse facilities. Working with ALG has made this detailed process both a success and a valuable learning exercise. Year after year the results have been professional, on time and on budget. We look forward to many more years of verification success with ALG."
