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 take part in Earth Hour. For 60 minutes people in more than 7,000 cities in over 190 countries switch off their lights as a symbolic gesture of solidarity to show they care about our planet and its future.

Earth Hour isn't just about switching off your lights. Our aim is to spark global conversations on the impacts of climate change and inspire positive action to protect our natural world. By working together we can help shape a bright future for us all.

This year, Earth Hour is at 8:30 pm local time Saturday 25 March. We're inviting all Australians to sign up to take #TimeOutForNature and join the global community of millions supporting stronger action on climate change
