To ask the Secretary of State for Environment, Food and Rural Affairs what the estimated volume of emissions of sulphur dioxide was in (a) large combustion plants and (b) total in each year since 1997.
Information on the total emissions of sulphur dioxide is held in the National Atmospheric Emissions Inventory (NAEI) and is publicly accessible via the NAEI's website. The latest year for which verified data is available is 2005, although 2006 data will be available shortly.
Information on large combustion plant emissions has been derived from the pollution inventories managed by the relevant environment agencies.
A summary table of the annual emissions data, in kilo tonnes, for 1997-2005 for sulphur dioxide is shown as follows:
