Annual nitrous oxide emissions in Canada 1990-2022

Nitrous oxide (N₂O) emissions in Canada were equivalent to 44.6 million metric tons of carbon dioxide (GtCO₂e) in 2022, an increase of four percent from the previous year. Canada's annual N₂O emissions have risen by more than 15 percent since the turn of the century. N₂O is a potent greenhouse gas with a far greater warming potential than CO₂ and has a lifetime of more than 100 years. It is primarily emitted from agricultural processes.

2022年，加拿大氮氧化物（N₂O）排放量相当于4460万吨二氧化碳（GtCO₂e），较上年增长了4%。自世纪初以来，加拿大的年N₂O排放量已上升超过15%。N₂O是一种强效温室气体，其温室效应潜力远大于二氧化碳，其在大气中的寿命超过100年。其主要来源于农业活动。
