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. Just one year later, Earth Hour became a global phenomenon with over 35 countries, and an estimated 50-100 million people participating.

2017 will mark the 10th anniversary of Earth Hour as a global phenomenon. What started as an Aussie idea has grown into a global force of nature, that is now celebrated in over 172 countries and over 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 home-grown success story: an Aussie campaign designed to draw attention to tackling global warming and get people talking about what we can do to help.

In Australia, Earth Hour is something that really brings communities together, with 1 in every 4 Aussies taking part. In 2016, millions of Australians took part in Earth Hour to show their support for a low pollution, clean energy future, one in which we can continue to enjoy the best of nature and our great Aussie outdoor lifestyle.

10 years of Earth Hour

In 2017, WWF is celebrating 10 years of Earth Hour and 10 years of progress on changing climate change.

We have come a long way in the last decade. Australian states and territories are now going full steam ahead with their ambitious targets for renewable energy. Right now about 1 in 7 Aussie households have solar panels installed on their roofs - we sure love our sun!

Earth Hour as a global movement has seen remarkable results. Last year 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.

More than ever, our actions on climate change today will shape the future for our children. Since they were born, our children have been taught to be active recyclers, aware of renewable power alternatives, and informed about the effects of pollution on our planet. They know more about climate change than any other generation. And they have extraordinary views on what they want for their planet.

Yet our future is under threat from rising temperatures and more extreme weather. Small changes to our climate as a result of increased carbon pollution are messing up the delicate balance of nature that we enjoy so much.

On Saturday, 25th March, switch off to support progress for the next generation. Switch off to #JoinTheFuture.

Planet to Plate: The Earth Hour Cookbook

As part of the 2015 campaign, Earth Hour launched an Australian-first cookbook, Planet to Plate.

The cookbook features recipes from our top celebrity chefs, stories from farmers about the ways increased carbon pollution is affecting them, and information on how Australians can get involved to safeguard our country’s great food industry into the future.
