Reporting to the Greenhouse Gas Emissions Reporting Program

Under the authority of Section 46 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), operators of facilities that meet the criteria specified in the annual notice with respect to reporting of greenhouse gases (GHGs), published in the Canada Gazette, are required to report facility GHG emissions to Environment Canada by the annual June 1st reporting deadline.

New! The Notice with respect to reporting of greenhouse gases (GHGs) for 2015, which requires the reporting of 2015 GHG emissions data, was published in the Canada Gazette Part I on October 17, 2015. There are no changes to the reporting requirements from last year. Companies that reported their facility emissions in the previous year must inform Environment Canada if their facility(ies) does not meet the current year reporting criteria. The latest technical guidance is also available to support facilities in reporting their 2015 emissions.

The 2014 data collection is complete. The Single Window system will remain open for the submission of any new reports for 2014 and updates to previous years. Updates on the reporting system for 2015 GHG data collection will be posted here in the spring of 2016.

Environment Canada’s Single Window system consists of a central web tool called the Single Window Information Manager (SWIM), where reporters can manage organizational information and which connects to a series of reporting modules that support various partner programs, including Environment Canada’s Greenhouse Gas Emissions Reporting Program. The Government of Canada GCKey Service or Sign-In Partners is used to log into the Single Window system. The Single Window system streamlines the reporting to national and various provincial jurisdictions, thus helping to reduce the reporting burden and the overall costs to governments. Provincial partners using this system for GHG reporting include Alberta, British Columbia and Ontario.

See Related Resources for additional information.

Previous years' reporting requirements can be found under GHGRP Notices - Canada Gazette, Part I. Key changes that were made to federal reporting requirements in previous years included:

  • updates to the Global Warming Potential (GWP) values that facilities are required to use to assess whether they meet the 50-kilotonne (kt) carbon dioxide equivalent (CO2 eq.) reporting threshold and in reporting their emissions (issued in the 2013 Notice);
  • a requirement to report facility latitude and longitude information (except pipeline transportation systems) (issued in the 2013 Notice);
  • a reduction of the reporting threshold from 100 kilotonne (kt) to 50 kt of CO2 eq. (issued in the 2009 Notice);
  • the disaggregation of the reporting category Venting and Flaring Emissions to two separate categories, Venting Emissions and Flaring Emissions (issued in the 2009 Notice); and
  • the disaggregation of the reporting category Waste and Wastewater Emissions to two separate categories, Waste Emissions and Wastewater Emissions (issued in the 2009 Notice).
