About Earth Hour

Shifting from a moment to a movement

The Earth Hour Story


Earth Hour launched in Sydney in 2007, with 2.2 million people and 2,100 businesses participating in the ‘lights off’ event.

What started as an Aussie idea is now celebrated in over 180 countries and 7,000 cities and towns worldwide. The symbolic hour has grown into the world’s largest grassroots movement for the environment, with beyond-the-hour projects and initiatives happening throughout the year. Earth Hour is a great Aussie home-grown success: designed to draw attention to tackling global warming and get people talking about what we can do to help.

Earth Hour as a global movement has seen remarkable results. In 2015, the world came together to bridge our differences in a landmark global agreement in Paris to tackle climate change. We have seen 3.4 million hectares of marine parks protected in Argentina, an Earth Hour Forest in Uganda established, and a ban on plastic bags in the Galapagos Islands. Every individual voice, in chorus with the world during Earth Hour, has created an unstoppable momentum for our planet.

In Australia, Earth Hour is something that really brings communities together, with 1 in every 4 Aussies taking part. In 2017, millions of Australians took part in Earth Hour to show their support for a low pollution, clean energy future.

Switch off for Earth Hour on Saturday, 24 March 2018, 8.30 pm local time.
