Nitrous Oxide: Definitely No Laughing Matter When It Comes To Global Warming

Launched on February 22, the Nitrous Oxide Focus Group will engage with many organisations including the National Farmers Union, Marks & Spencer, British Sugar, Defra, the Country Land and Business Association and Unilever.

The group will present and explore cutting edge research into the sources and sinks of nitrous oxide in the environment and discuss the prospects of mitigating the release of this destructive gas through re-shaping current policies and practice.

"People are becoming increasingly concerned about the immense problems associated with the unregulated release of this potent greenhouse gas," said Prof David Richardson, Dean of the Faculty of Science at UEA and co-ordinator of the Nitrous Oxide Focus Group.

"It is very encouraging that so many key figures from agriculture, industry and government are interested in mitigating nitrous oxide emissions by learning more about key research questions that are currently being addressed with government funding by groups within UEA, along with collaborating research groups across the UK and Europe."

Better known as 'laughing gas', nitrous oxide (N₂O) accounts for 9 per cent of all greenhouse gases, yet is 300 times more potent than carbon dioxide (CO₂). As a result its longevity in the atmosphere provides a potentially more damaging legacy than CO₂.

Agriculture accounts for around 70 per cent of N₂O emissions. The sources are mainly from soil micro-organisms that make N₂O from nitrogen-rich fertilisers added to soils to maximise crop yields. Other significant biological sources of N₂O come from the wastewater treatment industries where the greenhouse gas is again produced from micro-organisms.

The launch of the new consortium is underpinned by more than five years of interdisciplinary research at UEA and comes as significant new research on an N₂O-generating enzyme from a widespread soil bacterium is published.

Published in the Journal of Biological Chemistry February 15 2008, the research was done in collaboration with the University of Stockholm and largely carried out by UEA graduate Faye Thorndycroft under the guidance of Prof Richardson and Dr Nick Watmough.
