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!
Earth Hour was famously started as a lights-off event in Sydney, Australia, in 2007. Since then it has grown to engage more than 172 countries and territories worldwide.
