§ Mr. Skeetasked the Secretary of State for the Environment what information he has as to the categories of industrial plants in the United Kingdom, apart from thermal power stations, substantially increasing the quantity of sulphur dioxide in the atmosphere.
§ Mr. Giles ShawInformation on sulphur dioxide emissions from fuel combustion by type of consumer is given in the "Digest of Environmental Pollution and Water Statistics" published by my Department. The latest published figures—which relate to 1980—show that power stations contributed 61 per cent. of the total emissions and that the next largest industrial category was the refineries with 6 per cent. Separate figures for other categories of industry are not readily available but together they contributed 22 per cent. A rough calculation indicates that no single category contributed more than 3 per cent.
