California Electronic Greenhouse Gas Reporting Tool

The California Electronic Greenhouse Gas Reporting Tool, or Cal e-GGRT, must be used for submitting GHG data reports.

Cal e-GGRT is available for reporting required GHG data.

For assistance contact the GHG Reporting Help Desk.  Cal e-GGRT Help, instructions, spreadsheets, and other information.

Archived Cal e-GGRT Training Sessions

These training sessions were provided during 2012 and are still generally applicable for current reporting. Also see the posted regulation guidance and training resources.

U.S. EPA e-GGRT Training

The Cal e-GGRT reporting framework and “look and feel” is similar to the U.S. EPA e-GGRT system. For this reason the more detailed U.S. EPA training materials for specific reporting sectors are helpful for using the Cal e-GGRT system. Also see the ARB Reporting Guidance documents.

Cal e-GGRT includes numerous additions to support cap-and-trade, verification, and other ARB programs. Because of the differences between ARB and U.S. EPA reporting requirements, data submitted to U.S. EPA will not meet ARB reporting requirements. Therefore, separate reporting to Cal e-GGRT is required. Also, additional data elements provided in Cal e-GGRT must be completed.

The previous CARB reporting tool will remain active for generating reports and approved data revisions, but it will no longer accept new data. All data from 2011 onward will be reported via Cal e-GGRT.
