History
Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change.
In 2008 Earth Hour became a global sustainability movement with more than 50 million people across 35 countries participating.
Global landmarks such as the Golden Gate Bridge in San Francisco, Rome's Colosseum and the Coca Cola billboard in Times Square, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.
