Nitrous oxide (N2O)

Nitrous oxide is an ozone depleting substance. Despite its low emission volumes, its greenhouse gas impact is over 300 times bigger per unit weight than, for example, that of CO2. The most important sector causing N2O emissions is agriculture and more specifically soil emissions caused by nitrous fertilising.
