Speak up for why nature matters & join the movement today!

From changing individual behavior, to legislation, Earth Hour has achieved massive environmental impact - but as accelerating climate change and staggering biodiversity loss threaten our planet, we need to spark never-before-had conversations on the loss of nature and the urgent need to protect it.

Every year millions of people, businesses and landmarks set aside an hour to host events, switch off their lights and make noise for the Earth Hour movement. This year, we want to celebrate the diversity of life on Earth, and we want to invite your friends and family to celebrate with us!
