Dr Julian Lewis: To what extent does the hon. Gentleman consider that the Houses of Parliament contribute, by means of their output, to global warming?

[Nick Harvey (representing the House of Commons Commission): I shall resist the temptation that the hon. Gentleman presents to make any puns. A great deal of work is being done to examine our energy conservation and waste management and on other environmental fronts. Given the constraints that we are under with a building of such an age, we are doing what can to keep our environmental impact to a minimum.]
