Greenhouse Gas Reporting Program (GHGRP) (Annual Notice)

Last updated: 22 February 2022

The Minister of the Environment publishes an annual notice pursuant to authority granted by the Canadian Environmental Protection Act, 1999, requiring any operator of a facility above the reporting threshold (10,000 tonnes of CO2 equivalent) to report the total quantity of the listed greenhouse gas (GHG) emissions. The List includes CO2, CH4, HFC and PFC emissions, among others. The Minister of Environment publishes all information submitted in response to the annual notice.


Canada established the Greenhouse Gas Reporting Program (GHGRP) in 2004. The programme was significantly expanded for the reporting year 2017 and 2018, with a reduced reporting threshold (reduced to 10 kt CO2 eq. from 50 kt CO2 eq. between 2009 and 2016). In addition, facilities in covered industries were required to use specified quantification methods and report additional information. In 2021, the covered sectors include mining, ethanol, lime, cement, aluminium, iron and steel production, electricity and heat generation, ammonia, nitric acid, hydrogen, petroleum refining, pulp and paper, and base metal.


Reporting can be filed through the "Single Window" system. The system allows operators to file a single report to satisfy requirements at the national and provincial level. It is currently used by the following provinces: Alberta, British Columbia, Ontario, New Brunswick, Nova Scotia, and Saskatchewan.
