Earth Hour is WWF’s global environmental movement. Born in Sydney in 2007, Earth Hour has grown to become the world’s largest grassroots movement for the environment, inspiring individuals, communities, businesses and organizations in more than 170 countries and territories to take tangible climate action for over a decade. The movement recognizes the role of individuals in changing climate change and harnesses the collective power of its millions of supporters to shine a light on climate action.

On Saturday March 25th at 8:30pm, millions of people across the world are switching off lights for one hour to celebrate their commitment to the planet.

Earth Hour is a simple idea that turned into a global phenomenon, with hundreds of millions of people coming together to display a commitment to protect the one thing that unites us all – our planet.

Earth Hour starts with a simple flick of the lights at 8:30 pm on March 25, 2017 in a collective display of commitment to create a better future for the planet. But Earth Hour is more than just this hour. Uniting behind a common purpose demonstrates that we can make a meaningful difference. Earth Hour is our chance to make our commitment to protecting our planet not just for one hour a year, but every day.   It is not  too late to be a part of something big.
