In 2007, more than two million Sydney businesses and households turned off their lights for one hour - Earth Hour - sending a powerful global message that it’s possible to take action on climate change.
Just one year later, Earth Hour reached more than 50 million people in 35 countries across 18timezones, and the campaign shifted from a Sydney event to a global sustainability movement.
In 2009, Earth Hour aims to reach one billion people in 1000 cities worldwide. If you want to bring Earth Hour to your town or city on 28 March 2009 at 8:30pm, this will help you get started!
