Earth Hour:
60 minutes to protect the planet
An hour long event

Around the globe, millions of people, businesses, and landmarks set aside an hour to host events, switch off their lights, and make noise for climate change action. This year Earth Hour is at 8:30pm on 24 March 2018.

Run by you

Earth Hour belongs to you. Each year, millions of you come together to make Earth Hour happen. Coordinated by WWF and other volunteer organisations, together we're shining a light on the need for action on climate change.

Creating impact

Earth Hour is more than an event. It is a movement. Over the last 10 years, we have achieved massive environmental impact. Together with your support, we're helping change laws, lives and our planet! How great is that?

Beyond the hour

Funded projects

Together, we've funded WWF projects all over the globe, including providing communities with climate-smart boats after typhoon Haiyan and bringing solar power to families in India.

Advocated for change

Earth Hour supporters have successfully advocated for more climate-friendly laws and policies, such as those that have banned plastic in the World Heritage site of the Galapagos Islands .

Changing lives

We've helped bring real change to the lives of thousands of people around the world such as when we provided families with fuel-efficient stoves in Nepal & Madagascar .
