California AB 32

The Global Warming Solutions Act of 2006 (also known as Assembly Bill 32 or AB 32) was signed into California State Law by Governor Arnold Schwarzenegger on September 27, 2006.  AB 32 required the California Air Resource Board (CARB) to develop and enforce a mandatory regulation for greenhouse gas (GHG) emissions reporting in the state of California.  CARB implemented a regulation in 2007 that required certain facilities to report and verify their AB 32 greenhouse gas emissions.

Greenhouse Gas Reporting in California

The current version of the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions applies to many facilities in the state of California.  Certain facility categories are required to report their annual greenhouse gas emissions to CARB regardless of their emissions level, while other types of facilities are only required to report if emissions exceed 10,000 metric tonnes of CO2 equivalents.  An abbreviated list of facility types subject to reporting is provided below.

Facilities Subject to GHG Reporting Regardless of GHG Emissions Levels Facilities Subject to GHG Reporting Regulation if GHG Emissions Exceed 10,000 MTCO2e
Electricity Generation Units Subject to 40 CFR 75 Stationary Fuel Combustion
Cement Production Glass Production
Lime Manufacturing Hydrogen Production
Nitric Acid Production Iron/Steel Production
Petroleum Refineries Pulp/Paper Manufacturing
Geological Sequestration of CO2 Petroleum/Natural Gas Systems
CO2 Injection Geothermal Electricity Generation
Lead Production
AB 32 GHG Reporting

Facilities are currently required by CARB to report their greenhouse gas emissions electronically via the California Electronic Greenhouse Gas Reporting Tool (Cal e-GGRT).  The greenhouse gas emissions reports are due by April 10th each year.  For electric power entities, the greenhouse gas emissions reports are due by June 1st each year.

GHG Verification

Entities that are required to report greenhouse gas emissions to CARB are also required to hire a CARB-approved Accredited Verification Body to verify the greenhouse gas emissions report. Davenport Engineering has extensive expertise with CARB’s greenhouse gas reporting regulation.  We have assisted our clients with AB 32 reporting since 2007.  We have helped our clients:

1)  Determine applicability of the AB 32 reporting regulation to their operations

2)  Calculate greenhouse gas emissions in accordance with the procedures outlined in the regulation

3)  Anticipate and address changes in the AB 32 regulation that will impact their potential emissions

4)  Develop and maintain Greenhouse Gas Monitoring Plans that comply with the reporting regulation.

5)  Report accurate greenhouse gas emissions using the Cal e-GGRT web tool.

6)  Identify and address weak points in the facility’s AB 32 compliance strategies.

Davenport Engineering has extensive experience reporting GHG emissions for numerous business and industrial segments with a particularly strong emphasis in the oil & gas, process emissions, and transaction sectors.
