Reporting greenhouse gas emissions

Information and guidance on reporting to the Greenhouse Gas Reporting Program (GHGRP).  

The Notice with respect to reporting of greenhouse gases (GHGs) for 2018 was published on January 19, 2019 in the Canada Gazette. The notice describes who must report and what information must be reported by June 1, 2019.

The Single Window system is now open for 2018 reporting. You can submit your report for 2018 if your facility meets the criteria described in the above notice.

The 2018 notice contains the following key changes - expanded data and methodological requirements now apply to the following sectors:

  • aluminium production
  • ammonia production
  • base metal production
  • cement production
  • CO2 capture, transport, injection or storage
  • electricity or heat-steam generation
  • ethanol production
  • hydrogen production (refineries or stand-alone)
  • iron and steel production
  • lime production
  • mining
  • nitric acid production
  • petroleum refineries
  • pulp and paper production

Facilities that reported their emissions in the previous year must inform us if they do not meet the current year’s reporting criteria by submitting a Does Not Meet Criteria (DNMC) report through the Single Window system.

Use the Single Window system to report your information. This system streamlines the reporting to national and various provincial jurisdictions, and helps reduce the reporting burden and overall costs to governments. Provincial partners using this system for GHG reporting include:

  • Alberta
  • British Columbia
  • Ontario
  • New Brunswick
  • Nova Scotia
  • Saskatchewan

Information sessions

The GHGRP will be conducting information sessions in April 2019 to explain the 2018 reporting requirements and how to report. An email communication will be sent to our distribution list, inviting those who wish to attend to register for the sessions. The website will also be updated with links to register for the sessions.

Greenhouse gas reporting notices in the Canada Gazette

Under the GHGRP, a notice is published every year in Part I of the Canada Gazette. The notice describes who must report and what information must be reported.

Notices for previous years' reporting requirements covering 2004 to 2011 are available at Government of Canada Publications or can be requested from the GHGRP.

Key changes that were made to federal reporting requirements in previous years included:

  • a reduction of the reporting threshold (from 50 kt to 10 kt of CO2 eq.) and new requirements for specific sectors to report additional information following prescribed methodologies (issued in the 2017 Notice)
  • updates to the global warming potential (GWP) values that facilities are required to use to assess whether they meet the specified 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 kt to 50 kt of CO2 eq.) and a further breakdown of specific emission source categories (issued in the 2009 Notice)
