To ask the Chancellor of the Exchequer what specific measures Her Majesty's Treasury has taken to promote energy efficiency; and by what amount and what percentage of its total energy bill Her Majesty's Treasury's energy bill has been reduced over the past year.

On the measures taken and to be taken to promote energy efficiency within Her Majesty's Treasury, I refer the hon. Member to the answer that I gave to the hon. Member for Holborn and St. Pancras (Mr. Dobson) on 28 June 1990 at column 291. As to associated financial savings, for financial year 1990–91 it is estimated that the department will reduce its total energy bill by approximately £5,000 or 2 per cent. of its 1989–90 spend.
