The indicator reports emissions from human-related activities only. It does not include emissions from natural sources such as forest fires or volcanoes. The category ""other sources"" includes agriculture (livestock, crop production and fertilizer), building heating and energy generation, electric utilities, home firewood burning, incineration and waste, off-road vehicles and mobile equipment, the oil and gas industry, paints and solvents and other miscellaneous sources. The other ore and mineral industries include the aluminum industry, the asphalt paving industry, the cement and concrete industry, foundries, iron and steel industry, iron pelletizing mining and rock quarrying and the mineral products industry. For more details on the sources, consult the Data sources and methods (www.canada.ca/en/environment-climate-change/services/environmental-indicators/emissions-harmful-substances-air.html#DSM). 2024 results should be interpreted with caution. Following the publication of the Air Pollutant Emissions Inventory (APEI) in March 2026, a facility in Newfoundland and Labrador submitted a correction to its reported 2024 emissions data in the National Pollutant Release Inventory (NPRI), in August 2026 (reduction from 15.7 to 1.6 tonnes). The correction is expected to reduce the 2024 emissions totals and will be reflected in the next release of the APEI, planned for March 2027.",,,,,, Source: Environment and Climate Change Canada (2026) Air Pollutant Emission Inventory (www.canada.ca/en/environment-climate-change/services/pollutants/air-emissions-inventory-overview.html).,,,,,, Available on the Environmental indicators website (www.canada.ca/environmental-indicators).,,,,,,
