Greenhouse gas (GHG) emissions reports are due on March 31 of each year for GHG emissions emitted during the previous calendar year.

Certain suppliers and vehicle manufacturers will report GHG emissions at the corporate level. However, for most sources, the reporting is done at the facility level.

Reporting schedule

Each applicable facility or supplier must electronically submit an annual GHG report to the EPA by March 31 of each year for GHG emissions during the previous calendar year. Facilities and suppliers should submit their GHG emissions report using EPA's Electronic Greenhouse Gas Reporting Tool (e-GGRT).

Sources that become subject to reporting requirements in the middle of the year must report for the portion of the year beginning with the first month of operation and ending December 31.

Owners and operators of GHG sources must also keep a number of records. The records must be kept for at least 3 years from the date of submission.
