To ask the Secretary of State for the Environment if he will give an estimate of annual United Kingdom emissions of nitrous oxide broken down by source; and of the relative global warming effect of nitrous oxide in comparison with other United Kingdom emissions of gases with global warming potential.
Provisional estimates made by Warren Spring Laboratory for my Department are as follows:
|United Kingdom emissions of nitrous oxide—provisional estimates for 1990 (thousands of tonnes per year)|
|Production of adipic acid for nylon manufacture||90||57|
|Emissions from soil||65||41|
|Other fuel combustion||2||1|
