Ammonia Emissions

In 2013, ammonia (NH3) emissions were 492 kilotonnes (kt), an increase of 12 kt (2%) over 2012 levels. NH3 emissions in 2013 were 90 kt (22%) higher than in 1990. The change in emission levels over the period is due to increased agricultural fertilizer use and larger livestock populations.

Sources of ammonia emissions

In 2013, agricultural activity accounted for 94% (460 kt) of the total NH3 emissions in Canada (492 kt). Emissions from industrial sources represented 3% (14 kt) of national emissions, followed by transportation (road, rail, air and marine) and other sources, each representing 2% (8 kt and 10 kt) of national emissions. From 1990 to 2013, NH3 emissions from agricultural sources increased by 99 kt.

How this indicator was calculated

Note: The indicator only reports air pollutant emissions from human-related sources. The source "Other sources" does not include NH3 emissions from agriculture, as it is presented for the purpose of this chart as a stand-alone source. "Other sources" include home firewood burning, off-road vehicles, fuel for electricity and heating, incineration and miscellaneous and other open sources (such as waste). Industry includes the oil and gas industry and other industries. Consult table 1 in the Data Sources and Methods for a complete list of the air pollutant emissions sources included under each category.

Ammonia emissions by province and territory

Alberta contributed the most to Canada's NH3 emissions in 2013, with 29% (142 kt) of the national total (492 kt). Saskatchewan ranked second, with 21% (102 kt). Ontario and Quebec emitted the next highest proportions, with 18% and 14% (89 and 69 kt), respectively. For all provinces, livestock farms and the application of fertilizers were the most important sources of NH3 emissions. Almost all of the increase in emissions between 1990 and 2013 took place in Manitoba, Saskatchewan and Alberta.

Ammonia 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 zoom in to local areas and obtain details on NH3 emissions specific to reporting facilities.
