The world will “switch off” and #Challenge60 on Saturday, 23rd March, as Earth Hour returns for its eighteenth consecutive year

Earth Hour, the world’s biggest movement to protect our planet, is back and will be taking place on Saturday, 23rd March, from 8:30 pm to 9:30 pm.


Born in Sydney in 2007, Earth Hour has since gained millions of supporters in 190 countries and territories and more than 7,000 cities. It’s a community-led movement focused on raising awareness of the impacts of climate change and the importance of biodiversity.

For 2024, Earth Hour 2024 is helping raise funds to support critical conservation projects to protect wildlife and wild places by taking part in #Challenge60. Whether it is a walk, run, swim or cycle, participants are encouraged to get outdoors for 60 minutes to raise funds for nature.

Australia urgently needs to scale up solutions to address the escalating threats of biodiversity loss and climate change. Australia is home to unique wildlife found nowhere else, but sadly we hold the record for the highest mammal extinction rate on the planet.

If we want to secure a healthy future for people and nature, then we need to act with urgency to help protect and restore our planet for everything that calls it home, so save the date and switch off this Earth Hour.


Saturday 23rd March from 8:30 pm to 9:30 pm

About Earth Hour

Earth Hour is WWF’s flagship global environmental movement. Born in Sydney in 2007, Earth Hour has grown to become one of the world’s largest grassroot movements for the environment; inspiring individuals, communities, businesses and organisations in more than 180 countries and territories to take tangible environmental action for over a decade. Historically, Earth Hour has focused on the climate crisis, but more recently Earth Hour has strived to also bring the pressing issue of nature loss to the fore. The aim is to create an unstoppable movement for nature, as it did when the world came together to tackle climate change. The movement recognises the role of individuals in creating solutions to the planet’s most pressing environmental challenges and harnesses the collective power of its millions of supporters to drive change.
