Make a statement and turn "Off" for one hour
March 25 8:30pm - 9:30pm
A record breaking 178 countries and territories took part in this year’s event, making it the biggest Earth Hour yet!
Millions of people and over 400 landmarks from around the world joined in to show they care about the future of our planet, including the Sydney Opera House, the Eiffel Tower, Big Ben and Houses of Parliament, and the Burj Khalifa.
Earth Hour 2017 will be on 25 March, but until then, there are plenty of other ways you can support WWF and do your bit for the planet.
