2.6 Ammonia (NH3)
In 2015, approximately 490 kt of NH3 were released in Canada (Table 2-8). NH3 emissions originated primarily from agriculture, which accounted for 94% (450 kt) of total emissions. All other sectors combined accounted for only 6% of emissions.
From 1990 to 2015, Canada’s NH3 emissions increased by 22% (87 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 2015. Emissions from fertilizer application, however, have been rapidly increasing since 2006, due to an increase in sales and use of synthetic nitrogen fertilizers. All other emission categories decreased by 24% (10 kt).
The most significant changes in NH3 emissions from 1990 to 2015 include:
- Agriculture: increase of 27% (97 kt)
- Animal production: increase of 7% (18 kt)
- Crop production: increase of 102% (78 kt)
- Other emissions, dominated by manufacturing, incineration and waste, and transportation and mobile equipment sources: decrease of 24% (10 kt)
