Greenhouse gas emissions from large facilities
Access PDF (588 kB)
Releases of greenhouse gases (GHGs) and their increasing concentrations in the atmosphere are leading to a changing climate. This change has an impact on the environment, human health and the economy. This indicator tracks and provides consistent information on GHG emissions from the largest emitting facilities in Canada.
- In 2018, 295 megatonnes (Mt) of GHGs in carbon dioxide equivalent (CO2 eq) were emitted by 1 706 facilities reporting to the Government of Canada’s GHG Reporting Program
- Emissions from the reporting facilities account for 40% of Canada's total GHG emissions
Greenhouse gas emissions from large facilities, Canada, 2018
The map of Canada displays the 2018 greenhouse gas emissions from 1 706 facilities across Canada (excluding pipeline transportation systems). Facilities are represented as colour-coded dots according to 6 classes of emissions ranging from below 50 to over 2 000 kilotonnes of carbon dioxide equivalent.

In 2018, there were more facilities reporting to the GHG Reporting Program compared to the previous year (1 706 compared to 1 622). Of these facilities, 1 066 facilities reported emissions in the 10 to 50 kilotonnes (kt) range and 100 facilities with emissions below 10 kt reported voluntarily. Total facility-reported emissions in 2018 increased to 295 Mt CO2 eq, from 292 Mt CO2 eq in 2017.
In 2018, mining, quarrying, and oil and gas extraction accounted for 38% of facility-reported emissions; manufacturing, 30%; and utilities, 25% while in 2005, mining, quarrying and oil and gas extraction accounted for 17%; manufacturing, 33%; and utilities, 44%.
Compared to 2005, total emissions from facilities emitting 50 kt or more decreased by 7 Mt (2%). Over the same period, the number of facilities emitting 50 kt or more has increased from 337 in 2005 to 540 in 2018.
Since 2005, emissions from facilities in the utilities sector have declined overall, while emissions from the mining, quarrying, and oil and gas extraction sector have steadily increased. Emissions from the manufacturing sector have risen since 2016 although the sector’s emissions had significantly decreased between 2005 and 2009.
About the indicator
About the indicator
What the indicator measures
The indicator reports the total emissions of large GHG emitters in Canada for the year 2018.
In March 2004, the Government of Canada announced the introduction of the Greenhouse Gas Reporting Program to annually collect emission information for facilities across Canada. Unlike Canada's National Inventory Report, which compiles GHG data at the national and provincial/territorial levels and covers all GHG sources and sinks in Canada, the GHG Reporting Program applies only to specific emission sources that exist at large GHG-emitting facilities (industrial and other types of facilities).
The GHG Reporting Program requires all facilities that emit the equivalent of 10 000 tonnes (10 kilotonnes) or more of GHGs (in carbon dioxide equivalent units) per year to submit a report to Environment and Climate Change Canada. Mandatory reporting of GHG emissions by facilities was established by the Minister of the Environment under the authority of section 46 of the Canadian Environmental Protection Act, 1999.
Why this indicator is important
The release of GHGs and their increasing concentrations in the atmosphere are having significant impacts on the environment, human health and the economy. The indicator informs the public and decision makers on the release of GHG emissions from the largest emitting facilities in Canada. Consult Greenhouse gas emissions: drivers and impacts for information on the human health, environmental and economic impacts of greenhouse gas emissions.
The GHG Reporting Program ensures that the GHG emissions from Canada's large emitters are tracked and reported. This mandatory reporting contributes to the development, implementation and evaluation of climate change and energy policies and strategies in Canada.
Greenhouse gas emissions data reported through the GHG Reporting Program are used to inform the development of estimates of GHG emissions in Canada in the National Inventory Report, and to support regulatory initiatives.
The Greenhouse gas emissions indicators report trends in total anthropogenic (human-made) GHG emissions at the national level, per person and per unit gross domestic product, by province and territory and by economic sector.
The Global greenhouse gas emissions indicator provides a global perspective on Canada's share of global GHG emissions.
The Carbon dioxide emissions from a consumption perspective indicator shows the impact of Canada's consumption of goods and services, regardless of where they are produced, on the levels of carbon dioxide released into the atmosphere.
The Progress towards Canada's greenhouse gas emissions reduction target indicator provides an overview of Canada's projected GHG emissions up to 2030.
Data sources and methods
Data sources and methods
The data used in the indicator are from Environment and Climate Change Canada's Greenhouse Gas Reporting Program.
The Greenhouse gas emissions from large facilities indicator uses data from the GHG Reporting Program. The data are collected on an annual basis. Facilities are required to report their GHG emissions to Environment and Climate Change Canada by June 1 of each year.
The GHG Reporting Program provides local GHG emissions data from large emitters in Canada (those producing 10 kilotonnes (kt) or more of carbon dioxide equivalent emissions per year). Facilities with emissions below 10 kt per year can voluntarily report their GHG emissions.
Starting with the 2017 reporting year, the GHG reporting threshold was lowered from 50 kt to 10 kt. As a result, more facilities were required to report their emissions compared to the previous years. Additional changes made included expanded data and prescribed methodological requirements for facilities in targeted industry sectors. See Canada’s Greenhouse Gas Quantification Requirements for more information.
The Canadian Environmental Sustainability Indicators’ interactive map provides facility GHG data for the years 2004 to 2018.
The quantity of GHGs released by each facility is calculated or measured by the reporting facility. The methods used to determine emissions are based on monitoring or direct measurement, mass balance, emission factors, engineering estimates and/or fuel and activity data. See the Technical guidance on reporting greenhouse gas emissions for more information.
Environment and Climate Change Canada requires facilities involved in certain industrial activities to follow prescribed methods to determine their emissions. This is part of the reporting program’s expansion initiated in 2017 to improve the quality and usability of the facility data. For reporting facilities that are not subject to the expanded requirements, they can choose the quantification methodologies most appropriate to their particular industry or application. However, these facilities must use methods for estimating emissions that are consistent with the guidelines developed by the Intergovernmental Panel on Climate Change and adopted by the United Nations Framework Convention on Climate Change, for the preparation of national GHG inventories. See the Technical guidance on reporting greenhouse gas emissions for more information.
Caveats and limitations
A facility is required to report to the Greenhouse Gas Reporting Program only if its GHG emissions exceed the reporting threshold of 10 000 tonnes (10 kilotonnes) in carbon dioxide equivalent for a given year.
Comparisons among years may be made, bearing in mind that some facilities might not have been required to report in years for which they did not exceed the reporting threshold. Attention to consistency and comparability in the dataset is needed when comparing emissions from year to year.
Different facilities in a given type of industry may also use different methods for estimating emissions.
