§ Mr. Ron Daviesasked the Secretary of State for the Environment what percentages of nitrogen oxide emissions in the United Kingdom are calculated by his Department to have originated in oil refineries in each of the last 20 years for which figures are available; and what forecasts his Department has made of such emissions.
§ Mr. WaldegraveThe percentage of United Kingdom nitrogen oxide emissions originating from oil refineries were as follows:
Year Percentage 1974 3 1975 2 1976 3 1977 2 1978 2 1979 2 1980 2 1981 2 1982 2 1983 2 These figures are available from my Department's Digest of Environment Protection and Water Statistics No. 7, 1984. Figures for earlier years are not available.
Specific forecasts of emission levels are not available, but I am not aware of any reason to expect that nitrogen oxide emissions from oil refineries will increase.
