What is Earth Hour?
WWF’s Earth Hour is the world’s biggest movement to protect our planet.
Every year hundreds of millions of people around the world in more than 7,000 cities in over 190 countries take part by switching off for 60 minutes as a symbolic gesture of solidarity to show they care about our planet's future.
This year, Earth Hour is at 8.30pm local time Saturday 25 March. We're inviting all Australians to sign up to #ShapeOurFuture and join a worldwide community of millions supporting stronger action on climate change. Individual actions can benefit our planet, while symbolically demonstrating support for a renewable future for our country, and for the world.
- Switch to solar power.
- Switching your ride
- Or just #SwitchOff your lights for Earth Hour to show your support for greater action on climate change.
If you're representing a group, look to our dedicated pages to find out how you can take part. We have resources to help individuals, schools, businesses and communities make the most of Earth Hour.
Will you join the movement? Let us know if you’ll be switching off for Earth Hour on Saturday 25 March 2022 at 8:30pm local time, and joining millions of people coming together to #ShapeOurFuture.
