To ask the Secretary of State for Energy and Climate Change what the amount of emissions of (a) ammonias, (b) nitrogen oxides, (c) particulates and (d) sulphur dioxide in the UK was in each year since 1990. (234495)

I have been asked to reply.

Estimates of annual emissions of (a) ammonias, (b) nitrogen oxides, (c) particulates and (d) sulphur dioxide in the UK source, for each year 1990-2006 are shown in the table.

These results, published as National Statistics by DEFRA on 13 March 2008, are the latest statistics on air emissions for the UK. The 1990-2006 figures in this Statistics Release are from the National Atmospheric Emissions Inventory for 1970-2006, produced for DEFRA and the Devolved Administrations by AEA Energy and Environment. This inventory covers all air pollutants excluding greenhouse gases.

UK national emission estimates are updated annually and any developments in methodology are applied retrospectively to earlier years. The next scheduled update is expected in March 2009.

The full statistical release ‘UK Emissions of Air Pollutants, 2006 results’ is currently published on the DEFRA website:

Please also refer to the Air Quality e-digest statistics page which is currently published on the DEFRA website. This describes the process of measuring emissions and the emissions inventory in detail.
