WWF's Earth Hour - sign up and switch off!

Earth Hour in Parliament

On Saturday 28 March 2009 at 8.30pm, people, businesses and iconic buildings around the world will switch off their lights for an hour – WWF’s Earth Hour.

Let’s help London take part. By switching off you can do your bit for climate change and make a real difference.

London Mayor Boris Johnson has suggested he’ll be sitting in a state of "tranquil calm" in his darkened office during WWF’s Earth Hour. What will you do?
