§ Mr. Speller
To ask the Secretary of State for the Environment (1) what estimate he has of the carbon dioxide emissions resulting from energy used in domestic buildings, from(a) coal, gas, electricity and oil sources, and (b) space heating, lighting, water heating, fridges/ freezers, washing machines and other electrical appliances;
(2) what research he has commissioned or he intends to commission on the potential of energy efficiency measures in the housing stock for reducing carbon dioxide emissions contributing to the greenhouse effect; and if he will make it his policy to summarise the results of such research and make copies available in the Library.
§ Mrs. Virginia Bottomley
The Warren Spring laboratory and the Building Research Establishment have made preliminary estimates of the carbon dioxide emissions resulting from energy use in domestic buildings in 1987 as follows:
The Department is currently considering how further studies of domestic efficiency and its carbon dioxide emission reduction potential can best be carried out. Where appropriate, results of such work will be made available in the Library of the House.
