Particulate Matter Emissions

In 2012, emissions of total particulate matter (TPM) were 689 kilotonnes (kt), a decrease of 35 kt (5%) over 2011 emission levels. Emissions of respirable particulate matter (PM10) decreased in 2012 by 12 kt (3%) from 2011 emission levels, to 367 kt. Emissions of fine particulate matter (PM2.5) decreased in 2012 by 10 kt (3%) from 2011 emission levels, to 272 kt.

When compared to 1990 emission levels, 2012 emissions were lower by 546 kt (44%) for TPM, by 288 kt (44%) for PM10, and by 196 kt (42%) for PM2.5. The decline in TPM, PM10 and PM2.5 emissions since 1990 is the result of a reduction in emissions from power plants, transportation and industries for which regulations and agreementsFootnote [1] were put in place.

Emissions of respirable particulate matter decreased in 2012 by 12 kilotonnes or 3% from 2011 emission levels, to 367 kilotonnes. Emissions of fine particulate matter decreased in 2012 by 10 kilotonnes or 3% from 2011 emission levels, to 272 kilotonnes. When compared to 1990 emission levels, 2012 emissions were lower by 546 kilotonnes (44%) for total particulate matter, by 288 kilotonnes (44%) for respirable particulate matter, and by 196 kilotonnes (42%) for fine particulate matter.

How this indicator was calculated

Note: PM10 refers to particulate matter with a diameter of 10 micrometres (μm) or less, while PM2.5 refers to particulate matter with a diameter of 2.5 μm or less. Emissions from natural sources (such as biogenics) and open sources (such as road dust) are not included. However, emissions from open sources related to waste (such as landfills) are included.

Particulate matter emissions by source

In 2012, TPM from industrial sources,Footnote [2] excluding the oil and gas industry, contributed the most to Canada’s TPM emissions representing 67% (462 kt). Home firewood burning emitted the next-largest proportion of national TPM emissions, representing 16% (108 kt), followed by off-road vehicles with 5% (36 kt). Between 1990 and 2012, industrial sources, excluding the oil and gas industry, had the largest reduction (427 kt) in emissions.

As for TPM, PM10 emissions from industrial sources,Footnote [3] excluding the oil and gas industry, contributed the most to Canada’s PM10 emissions with 44% (163 kt). Home firewood burning emitted the next-largest proportion of national PM10 emissions, representing 28% (102 kt), followed by off-road vehicles with 10% (36 kt). Between 1990 and 2012, industrial sources, excluding the oil and gas industry had the largest reduction (185 kt) in emissions.

PM2.5 emissions from the home firewood burning source were the largest emitting source in 2012 representing 102 kt (37% of the national total). Industrial sources, excluding oil and gas industry, emitted the next-largest proportions of national PM2.5 emissions, representing 31% (84 kt), followed by off-road vehicles with 13% (34 kt). Between 1990 and 2012, industrial sources excluding oil and gas industry had the largest reduction (114 kt) in emissions.

Particulate matter emissions from facilities

Environment Canada’s National Pollutant Release Inventory (NPRI) provides detailed information on air pollutant emissions from industrial and commercial facilities. The Canadian Environmental Sustainability Indicators (CESI) program provides access to this information through an online interactive map.

With the CESI interactive map, you can drill down to local areas and obtain details on TPM, PM10 and PM2.5 emissions specific to reporting facilities.

Particulate matter emissions by province and territory

Environment Canada is currently revising, in collaboration with provincial/territorial counterparts, the breakdown of total emissions by province and territory to reflect methodological improvements. Consequently, air pollutant emissions by province and territory could not be included in the update of the indicator at this time.
