Data Sources and Methods for the Greenhouse Gas Emissions from Large Facilities Indicator
2. Description and rationale of the Greenhouse Gas Emissions from Large Facilities indicator
In March 2004, the Government of Canada announced the introduction of the Facility Greenhouse Gas Emissions Reporting Program (GHGRP) for facilities. Unlike Canada's National Inventory Report (NIR), which compiles greenhouse gas (GHG) data at a national level and is developed from national and provincial statistics, the GHGRP applies only to the largest GHG emitters in Canada (industrial and other types of facilities). Through the GHGRP, all facilities that emit the equivalent of 50 000 tonnes (50 kilotonnes [kt]) or more of GHGs (in carbon dioxide equivalent [CO2 eq] units) per year are required to submit a report to Environment Canada. Mandatory reporting of GHG emissions by these facilities was established by the Minister of the Environment under the authority of sections 46 to 53 of the Canadian Environmental Protection Act, 1999 (CEPA 1999)
GHG emissions data reported through the GHGRP are used, where appropriate, to confirm estimates in the NIR. The extent to which the emissions data are used in the NIR is dependent upon the level of detail and type of data available.
The GHGRP ensures the mandatory reporting of GHG emissions by some of Canada's largest industrial emitters. Mandatory reporting of facility emissions provides a more precise picture of the sources and amounts of Canada's GHG emissions, thus contributing to the development, implementation and evaluation of climate change and energy policies and strategies in Canada.
2.3 Recent changes to the indicator
The global warming potentials (GWPs) used under the GHGRP were changed in 2013 to match the GWP values that are now used internationally and in the NIR.Footnote  Recalculations to the CO2 equivalent quantities for all previous years' data (2004–2012) were done to ensure the data is consistent and comparable across all years.
