Earth Hour

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 Australianstaking 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.
