Greenhouse Gas Reporting Program

Basic Information

In response to the FY2008 Consolidated Appropriations Act (PDF) (613 pp, 1.5MB, About PDF) (H.R. 2764; Public Law 110-161), EPA issued the Mandatory Reporting of Greenhouse Gases Rule (74 FR 56260) which requires reporting of greenhouse gas (GHG) data and other relevant information from large sources and suppliers in the United States. The purpose of the rule is to collect accurate and timely GHG data to inform future policy decisions. In general, the Rule is referred to as 40 CFR Part 98 (Part 98). Implementation of Part 98 is referred to as the Greenhouse Gas Reporting Program (GHGRP).

Suppliers of certain products that would result in GHG emissions if released, combusted or oxidized; direct emitting source categories; and facilities that inject CO2 underground for geologic sequestration or any purpose other than geologic sequestration, are covered in Part 98. Facilities that emit 25,000 metric tons or more per year of GHGs are required to submit annual reports to EPA. Part 98 was published in the Federal Register (www.regulations.gov) on October 30, 2009 under Docket ID No. EPA-HQ-OAR-2008-0508-2278.

Categories subject to Part 98 began reporting their yearly emissions with the 2010 reporting year. 2010 emissions were reported to EPA via the electronic greenhouse gas reporting tool (e-GGRT) in September 2011. Additional sources began reporting yearly emissions in September 2012, bringing the total to 41 source categories reporting.

In January 2012, EPA made the first year of GHGRP reporting data available to the public through its interactive Data Publication Tool, called Facility Level Information on GreenHouse gases Tool (FLIGHT), EPA will continue to update the tool and release additional data each reporting year.

If your business is or may be required to report GHG emissions to the GHGRP under Part 98, visit the For GHG Reporters page for more information about reporting requirements, deadlines, training, and the e-GGRT reporting system.
