Pacific Nitrous Oxide Emissions More Than Thought
This is the latest from the Arthur Rank Centre:
Nitrous Oxide is over 300 times more harmful than carbon dioxide and about 66% of man-made
Nitrous Oxide emissions come from agriculture.
It’s an important greenhouse gas because it’s very
efficient at absorbing energy and it stays in the atmosphere for a long time.
Natural emissions of N2O
can be increased by a variety of agricultural practices and activities, including the use of synthetic and
organic fertilisers, production of nitrogen-fixing crops, cultivation of high organic content soils, and the
application of livestock manures and slurries to growing crops.
