Organized by the World Wildlife Fund (WWF), Earth Hour started March 2007 in Sydney, Australia when 2.2 million individuals and more than 2,000 businesses turned their lights off for one hour to take a stand against climate change. It has grown ever since. Earth Hour 2010 was the biggest Earth Hour ever with hundreds of million of people participating. A record 128 countries and territories joined the global display of climate action. Iconic buildings and landmarks from Asia Pacific to Europe and Africa to the Americas switched off. People across the world turned off their lights and came together in celebration and contemplation of the one thing we all have in common - our planet.

This Earth Hour people are being asked to step it up beyond the hour, and to pledge to take personal action to make a difference through an online platform that captures and allows individuals, governments and organisations across the globe to share their actions.

"The challenges that face our planet are immense, but never underestimate the possibility for change when we face these challenges with true common purpose. Hundreds of millions of people around the globe have given us a glimpse of what is possible. It is now time to go beyond the hour and show what can be done - by the people for the planet," said Jim Leape, Director General of WWF.
