Earth Hour
On 31 March 2007, more than 2 million Sydney businesses and households turned of their lights for one hour - Earth Hour - sending a powerful national and global message that it's possible to take action on global warming.
In 2008, Earth Hour goes global. Major cities around the world will join us in taking a stand on the greatest threat our planet has ever faced, uniting millions of people to turn the tide on global warming.
Will you be part of Earth Hour?
