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.
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.

ABOUT
It started with a question: How can we inspire people to take action on climate change?
The answer: Ask the people of Sydney to turn off their lights for one hour.

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.

With Sydney icons like the Harbour Bridge and Opera House turning their lights off, and unique events such as weddings by candlelight, the world took notice. Inspired by the collective effort of millions of Sydneysiders, many major global cities are joining Earth Hour in 2008, turning a symbolic event into a global movement.
