Nitrous oxide (a molecule made of two nitrogen atoms and an oxygen atom) is over 300 times more potent as a greenhouse gas than CO 2 and accounts for 6.3% of all UK greenhouse gas emissions. If nations are to meet their climate change targets, they need to pay attention to N 2 O. read more
Nitrous oxide isn't a problem in the troposphere (where we live). However, it has low solubility in water (comparable to oxygen) , and, as such it sticks around for a long time. As it makes its way into the stratosphere, it becomes a potent greenhouse gas. read more
Nitrous oxide traps almost 300 times as much heat in the atmosphere than carbon dioxide over a 100 year period. It also reacts with ozone in the stratosphere and depletes the ozone layer. With the reduction in CFC usage, nitrous oxide is the most highly emitted ozone depleting substance. read more
