WWF is the parent organisation of Earth Hour and started Earth Hour with teams and partners in Sydney, Australia back in 2007.

SWITCH OFF the power tomorrow, April 28th, 2015, for at least one 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 participating, and an estimated 50-100 million people.

In 2014, Earth Hour was celebrated in over 162 countries and over 7000 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 3 Aussies taking part.

In 2015 we’re inviting you to once again join in the action as we throw our support behind Aussie food and farmers.

We grew up with healthy, homegrown food and we all want our children to have the same opportunity. But our food is already being affected by global warming. This includes everything from the bananas we enjoy on our breakfast cereal every morning and our avocado and Vegemite on toast, to our lunchtime ham, cheese, tomato and lettuce wrap, and spaghetti bolognese - our dinnertime favourite.

What's happening?

On March 28th 2015, thousands of food-related events and Earth Hour dinners will be taking place around the country.

Events will range from twilight picnics, to food fairs to night time farmers markets to paddock pop-up restaurants!

All events will be supporting Aussie farmers and highlighting how food and farming is being impacted by global warming.

You’re invited to host an event!
