Hundreds of millions of people, businesses and governments around the world unite each year to support the largest environmental event in history - Earth Hour.
Find out more about who we are, how we’ve grown, and why you should get involved.

More than 5,200 cities and towns in 135 countries worldwide switched off their lights for Earth Hour 2011, sending a powerful message for action on climate change. It also ushered in a new era with members going Beyond the Hour to commit to lasting action for the planet. Without a doubt, it’s shown how great things can be achieved when people come together for a common cause.

Global warming is the greatest threat facing our planet today. A warming planet alters weather patterns, water supplies, seasonal growth for plants and a sustainable way of life for us, and the world’s wildlife. Climate change has already started, but it’s not too late to take action. There’s still time for us all to be part of the solution.

Earth Hour happens because of the committed teams around the world that work tirelessly to get lights switched off. Coordinating their tremendous efforts is a small team of Sydney-siders – the Earth Hour Global Team.
