What is Earth Hour?

© Leonie Sii / WWF-Australia


Starting as a symbolic lights out event in Sydney in 2007, Earth Hour has grown to become one of the world’s largest grassroots movements for the environment. It’s been more successful than we ever imagined - inspiring and empowering individuals, communities, businesses and organizations in 190 countries and territories to take actions for climate change and nature loss.

While climate change remains a vital issue for our planet, we believe the spotlight must also focus on the accelerating loss of nature and the threats this poses to us all. It is ever more important to raise awareness that preserving nature is the critical foundation of a healthy planet and an immediate, powerful and cost-effective solution to climate disaster and pandemic prevention.

Earth Hour 2021 is not just a symbolic event, but a moment to take action for a lifetime! It’s time to Speak up for Nature - Nature Positive, for Us, and for our Planet.

Earth Hour then and now

Our relationship with the natural world is dangerously imbalanced. Recently, a series of catastrophic events – wildfires, extreme weather, locust plagues and the COVID-19 pandemic have shaken the world and we are still dealing with the unprecedented, tragic socio-economic, health and humanitarian consequences. It is clearer than ever that our future and the future of our planet are intrinsically linked and both are under threat. 2020 has proved to us that nature is essential for our existence and intact natural systems are imperative to all our futures. What we do to nature - we do to ourselves. We need to urgently mend our broken relationship with nature.

This year, Earth Hour is asking people to speak up for nature in as many diverse and creative ways as possible. We encourage people to join their local Earth Hour events, share their stories of why nature matters to them - or simply learn more about why climate change and nature loss are the two biggest environmental issues facing our planet today.

The time is now! We must speak up now to safeguard the health of our planet and in turn, our own health and well-being.
