Global share of nitrous oxide emissions 2022, by sector
In 2022, almost 70 percent of global nitrous oxide (N2O) emissions were linked to the agriculture sector. A major source of agriculture-related N2O emissions is the use of synthetic fertilizers.
N2O is a highly potent greenhouse gas, with a global warming potential (GWP) almost 300 times greater than carbon dioxide over a 100-year period.
