Reporting greenhouse gas emissions

Information and guidance on reporting to the Greenhouse Gas Reporting Program (GHGRP). Facilities that meet certain criteria must report their greenhouse gas (GHG) emissions by June 1 each year.

New! You can now submit your 2017 emissions report to the GHGRP through the Single Window system. Consult the Reporting Resources below to access our updated guidance and other helpful information.

The Notice with respect to reporting of greenhouse gases (GHGs) for 2017 describes who must report and what information must be reported by June 1, 2018.

There are 3 significant changes in the reporting requirements for 2017:

  1. The reporting threshold has been lowered from 50 000 tonnes to 10 000 tonnes (10 kilotonnes). All facilities that emit 10 kilotonnes or more of GHGs in carbon dioxide equivalent units (CO2 eq) per year must submit a report.
  2. All facilities engaged in carbon capture, transport and storage (CCTS), regardless of their annual GHG emissions, must submit a report covering these activities for 2017 and relevant years for the period 2014 to 2016.
  3. Expanded data and methodological requirements will apply to manufacturers of lime, cement, iron and steel, and aluminium; and to facilities engaged in CCTS.

Companies that reported their facility emissions in the previous year must inform Environment and Climate Change Canada if any of their facilities do not meet the current year reporting criteria.

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

The following links provide guidance for reporting to the Greenhouse Gas Reporting Program:

  • Technical Guidance on Reporting Greenhouse Gas Emissions (Updated!): a comprehensive overview of the GHG emissions reporting requirements, including guidance for potential reporters to help determine if they are required to submit a report, the greenhouse gases and emission sources subject to reporting, along with general information on methods for calculating emissions and the required reporting format.
  • Canada's Greenhouse Gas Quantification Requirements (New! For a copy, please contact us at ec.ges-ghg.ec@canada.ca): a detailed guide to the quantification methods and expanded reporting requirements that apply to lime, cement, iron and steel, and aluminium manufacturers, and to CCTS activities
  • Questions and Answers (New!): answers to questions you may have regarding the GHGRP reporting requirements
  • Access to Single Window system (Available!): log-in to the on-line reporting system to create and submit your GHG report
  • Instructions for using the Single Window system (Updated!) : provides step by step instructions on how to report your greenhouse gas information using the Single Window system.

Information sessions

In April 2018, the GHGRP conducted several information sessions to assist facilities in understanding the 2017 reporting requirements and preparing their GHG reports. The sessions were held online through WebEx.

Two types of sessions were held:

  1. The General Reporting Requirements information sessions presented an overview of the GHGRP and described the general reporting requirements (including the administrative and GHG emissions information to provide). These sessions were intended for facilities who may be reporting for the first time. A demonstration of our Single Window reporting system and steps to submit a GHG report was also given.
  2. The Expanded Reporting Requirements information sessions discussed the new requirements established through the GHGRP expansion for targeted sectors and activities (lime, cement, aluminium and iron and steel manufacturing, as well as carbon capture, transport and storage) and the provisional options for reporting. A demonstration of our Single Window reporting system was also given.

Recordings of the information sessions are available. To access these recordings and the associated slides, please contact us at ec.ges-ghg.ec@canada.ca.

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.

The 2017 notice (published December 20, 2017) marks the first phase of expanded GHG reporting requirements under the GHGRP.

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:

  • 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).
