What steps are being taken to turn off unnecessary lights on the House of Commons estate.

A campaign to raise awareness of environmental issues has been running for more than a year to encourage people to switch off unnecessary equipment and lighting. The campaign has included regular presentations, guest speakers, two exhibitions and articles in the staff magazine, "inHouse". It is reckoned that the most cost-effective way to control unnecessary lighting is for people to switch off lights when they leave rooms rather than to have automatic light systems that allow a time delay before switching lights off automatically.

I do not know who is responsible for keeping the lights on in Star Chamber Court throughout the day under the very expensive £450,000 glass canopy, but could they be instructed to turn them off during the day? For a Parliament that is meant to be interested in climate change, a remarkably large number of lights are left on throughout the daylight hours.

I will take note of the hon. Gentleman's specific point about the covered walkway and ask for officers to investigate that. I repeat that the most effective way to save electricity is simply for everybody on the estate to be more diligent about turning lights off.
