2010 Earth Hour

Earth Hour is organized by WWF. With almost 5 million supporters and a global network in over 100 countries, it’s one of the world's largest and most respected independent conservation organizations. WWF’s mission is to stop the degradation of the Earth's natural environment and build a future where people live in harmony with nature.

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.

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.
