Starting as a symbolic lights out event in Sydney in 2007, Earth Hour is now the world’s largest grassroots movement for the environment, inspiring millions of people to take action for our planet and nature.

From pushing for environmentally-friendly laws and policies to crowdfunding for a better future, YOU make Earth Hour possible. Coordinated by WWF and other volunteer organizations, Earth Hour’s greatest strength is the power of people.

As accelerating climate change and staggering biodiversity loss threaten our planet, Earth Hour endeavours to spark never-before-had conversations on the loss of nature and the urgent need to protect it.
