History of Earth Hour

2007

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.

2008

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.

2009

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.

2010

Earth Hour 2010 takes place on Saturday 27 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.
