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 2020 was published on February 13, 2021 in the Canada Gazette. The notice describes who must report and what information must be reported.

The Single Window system will be open for 2020 reporting in the coming months. At that time, you can submit your report for 2020 if your facility meets the criteria described in the above notice.

The 2020 notice does not contain any major changes. It builds on the 2019 notice which includes expanded data and methodological requirements that 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 who also use this system for GHG reporting include:

Alberta
British Columbia
Ontario
New Brunswick
Nova Scotia
Saskatchewan

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:

additional reporting requirements following prescribed methodologies expanded to additional sectors (issued in the 2018 notice)
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)
