I am sure that the hon. Gentleman would be shocked if I attempted to take responsibility for the parliamentary estate, which is clearly up to the House of Commons. This issue is strictly about central Government, not the parliamentary estate, but I would urge Mr Speaker, using all his great influence, to ensure that the parliamentary estate is performing just as well as central Government.
I warmly congratulate the Government on more than achieving their target, which stands in stark contrast with previous Governments. None the less, at a glance around the governmental estate—and the parliamentary estate, too—we see lights burning all night long, with no use of energy-efficient lighting. We also see the ambient temperature of Ministry of Defence buildings, such as the one in my constituency near Corsham, at 25°, which means that civil servants have to sit with their jackets off, because otherwise it would be too warm. Surely we should get our lights off at night and get the temperature down, so that people feel cold in the office and put sweaters on.
I hesitate to say this, but I entirely agree with my hon. Friend. We have set an ambitious target and there is more work to do. Whether that means getting people to put on woolly jumpers or getting them to turn the lights off, we will do it, and we shall continue our efforts.
