Earth Hour 2012

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 2011, hundreds of millions of people took part in the third Earth Hour. Over 4400 cities in 88 countries officially switched off to pledge their support for the planet, making Earth Hour the world’s largest global climate change initiative.

Earth Hour 2012 takes place on Saturday 31 March at 8.30pm (local time) and is a global call to action to every individual, every business and every community throughout the world. It is a call to stand up, to take responsibility, to get involved and lead the way towards a sustainable future. Iconic buildings and landmarks from Europe to Asia to the Americas will stand in darkness. People across the world from all walks of life will turn off their lights and join together in celebration and contemplation of the one thing we all have in common – our planet.

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.

With participation levels now exceeding all expectations, and with more cities and towns signing up every day to be a part of this historic event, the success of Earth Hour 2012 is limited only by the will of the global community to want a say in the future of their planet.

The challenge of Earth Hour is to rethink how we live our lives in the next hour, the next day, and the day after that.

It's always darkest before the dawn. Let's make this hour the dawn of a new greener age.
