The Biggest Hour for Earth is back
Last year, over 410,000 hours were given to our planet by supporters in over 190 countries and territories. This year, we're aiming to make the Biggest Hour for Earth even bigger, and once again create a moment the world can't miss.
Uniting for our one shared home
Since our beginnings in 2007, Earth Hour has been known for the “lights off” moment – a symbolic event to show our collective support for the planet. But in 2023, we're stepped things up, breathing new life into our movement and mission to create the Biggest Hour for Earth.
