Created to take a stand against the greatest threat our planet has ever faced, Earth Hour uses the simple action of turning off the lights for one hour to deliver a powerful message about the need for action on global warming.

On 31 March 2007, 2.2 million people and 2100 Sydney businesses turned off their lights for one hour - Earth Hour. This massive collective effort reduced Sydney's energy consumption by 10.2% for one hour, which is the equivalent effect of taking 48,000 cars off the road for one hour.

See the difference you can make.
Earth Hour 2007 was a Sydney event.
Earth Hour 2008 is a global movement.

This simple act has captured the hearts and minds of people all over the world. As a result, at 8pm on the 29 March, 2008 millions of people in some of the world's major capital cities, including Copenhagen, Toronto, Chicago, Melbourne, Brisbane, Tel Aviv and Manila will unite and switch off for Earth Hour.
