"This year is a particular year. We call it the 'super year' for nature and sustainability because leaders can and must take ambitious and decisive action both on climate and nature."

Earth Hour is WWF's flagship global environmental movement. Every year on the last Saturday of March, at 8.30 pm in their local times, millions of people in more than 180 countries and territories switch off the lights to show support for the planet.

Born in Sydney in 2007, the initiative has grown into one of the world's largest grassroots campaigns for the environment, inspiring individuals, communities, businesses and organizations in more than 180 countries and territories to take tangible environmental action.
