2.6 Ammonia (NH3)
In 2016, approximately 492 kt of NH3 were released in Canada (Table 2-8). NH3 emissions originated primarily from agriculture, which accounted for 94% (460 kt) of total emissions. All other sectors combined accounted for only 6% of emissions.
From 1990 to 2016, Canada’s NH3 emissions increased by 20% (82 kt) (Figure 2-6). This trend is driven by emissions from animal production and fertilizer application within the agriculture sector. Animal production, which dominates the emissions throughout the time series, experienced a steady increase in emissions from 1990 to 2005, followed by a decrease from 2006 to 2016. Emissions from crop production, however, have been steadily increasing since 2006 due to an increase in sales and use of synthetic nitrogen fertilizers.
The most significant changes in NH3 emissions from 1990 to 2016 include:
- agriculture: increase of 24% (90 kt)
- crop production: increase of 97% (77 kt)
- animal production: increase of 5% (13 kt)
- other emissions, dominated by manufacturing, incineration and waste, and transportation and mobile equipment sources: decrease of 31% (7.0 kt)
Long description for figure 2-6
Figure 2-6 displays the three major sections that contribute to national NH3 trends. The following table displays the contributions (kt) for the years 1990 to 2016.
