Earth Hour:
The countdown to secure the future of our home.

Beyond the Hour

Moment to movement

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.

Run by you

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 organisations, Earth Hour’s greatest strength is the power of people.

Protecting life on Earth

As accelerating climate change and staggering biodiversity loss threaten our planet, Earth Hour 2018-2020 endeavours to spark never-before-had conversations on the loss of nature and the urgent need to protect it.

Biodiversity

Nature's importance

Most of the resources we use come from the environment. That’s why we have to do our part to protect the world around us!

Connecting to Earth

People are just one part of Earth’s vast web of life. Let’s get back in touch with our roots and nurture nature by helping to conserve wildlife and their habitats.

Biodiversity

The variety of life and places where they live is our best defence against climate change! Such variety provides us with even more resources to improve our lives.
