Nitrous oxide (N₂O)
Nitrous oxide (N₂O) is a greenhouse gas that contributes to the greenhouse effect. In addition to natural sources, agricultural activities and using fertilisers are significant contributors to nitrous oxide emissions. Approximately 40% of total global N₂O emissions result from human activities. The Intergovernmental Panel on Climate Change (IPCC) has estimated that nitrous oxide accounts for about 6% of all greenhouse gas emissions.
