Earth Hour

Go Back

WWF started Earth Hour in 2007 to unite the world against climate change.

Every year, millions of people countdown together across the globe and take one iconic action: switch off the lights.

Together, participants have created a powerful movement that helps deliver strong global commitments to tackling climate change. It has become a catalyst for positive environmental impact, driving major legislative changes by harnessing the power of the people.

Climate change remains a big challenge for us all. But another urgent threat now demands our attention: the loss of nature. These two combined threats mean we must act – and now.

You can play your part just by flicking off the lights at home!
