ABOUT EARTH HOUR
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. Only a year later and Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries participating. Global landmarks such as the, Sydney Harbour Bridge, The CN Tower in Toronto, The Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.
In March 2009, hundreds of millions of people took part in the third Earth Hour. Over 4000 cities in 88 countries officially switched off to pledge their support for the planet, making Earth Hour 2009 the world’s largest global climate change initiative.

Why get involved?Put simply, because our future depends on it!
Earth Hour has done a lot to raise awareness of climate change issues. But there’s more to it than switching off lights for one hour once a year. It’s all about giving people a voice on the future of our planet and working together to create a sustainable low carbon future for our planet.
The future can be brightNew economic modelling indicates the world has just five years to initiate a low carbon industrial revolution before runaway climate change becomes almost inevitable. But it can be done, and the long term benefits will be enormous.
So now's the time to take a stand and give world leaders the mandate they need to make the right climate deal.
