The California Air Resources Board (CARB) has been working with the U.S. EPA to develop and launch an electronic tool that supports GHG reporting under AB 32 (California's Mandatory GHG Reporting Program). This tool, to collect calendar year 2011 GHG data, is expected to launch on February 23rdCal e-GGRT was launched on February 22, 2012.

Background

At the time the US EPA finalized its Mandatory Reporting of Greenhouse Gases Rule (40 CFR Part 98), more than a dozen states already had or were in the process of implementing their own greenhouse gas data collection programs, including California. As part of its commitment to work with states to harmonize data systems and, where possible, reduce reporter burden, EPA launched a State-EPA Integrated Project Team (IPT) on greenhouse gas data collection and exchange in 2010. Development of Cal e-GGRT was an outgrowth of this effort. Cal e-GGRT supports CARB's effort to harmonize its GHG data collection efforts under AB32 with EPA's Greenhouse Gas Reporting Program. Beginning with the submittal of 2011 data, CARB's annual GHG data reporting methods will gradually align with many of EPA's requirements. Over the next several years, CARB intends to harmonize its program with EPA's. The Cal e-GGRT reporting framework and "look and feel" is similar to EPA's e-GGRT system and should be familiar to California users of EPA's e-GGRT.

Why do CARB reporters need a separate tool from U.S. EPA e-GGRT?
Cal e-GGRT includes numerous modifications to support California's cap-and-trade program, verification, and other CARB programs. Because of the differences between CARB 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.
