Show you care about the future of our planet

Earth Hour is the moment every year when millions unite around the world to show they care about the future of our planet. More than a symbolic event, Earth Hour is a global environmental movement to stop the destruction of nature. 

This year, it's the start of an important decade for climate and nature action. By 2030, nature and wildlife could be recovering all around us. We could have green jobs, cleaner air and a healthier future for the next generation. Everyone has a part to play in making that happen. And it all starts with a single switch...

2021 Classroom Resources

This year our resources are focussing on nature and wellbeing activities for your students to enjoy in the lead up to Earth Hour – or on the night itself. You can also share your Earth Hour plans with us to gain access to our new Earth Hour Certificates. There's also a chance to win one of three WWF adoption packs for your class! 

Teachers: Get your Earth Hour certificates!

Tell us how your school is celebrating Earth Hour to access your Earth Hour certificate template, great for personalising for your school, class or students. You could also be entered into a draw to win one of three WWF adoption packs for your class! T&Cs apply.
