[A] Value for 1994 includes emissions from Nunavut, which was officially separated from the Northwest Territories in 1999. [B] Legacy data for 1994 cannot be attributed to any province or territory. Totals may not add up due to rounding. The indicator reports emissions from human-related activities only. It does not include emissions from natural sources such as forest fires or volcanoes. 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.
