At 8:00pm on March 29, cities around the world will turn off their lights for one hour to raise awareness for the need to take action on global warming. Earth Hour uses the simple action of turning off the lights for one hour to deliver a powerful message about the need for action on global warming.
Earth Hour is not just about turning off building lights. It’s about a long-term commitment to reducing global greenhouse gas emissions. Join the growing list of participants and sign up to participate in Earth Hour 08. Earth Hour is an initiative of the 'World Wide Fund for Nature’ (WWF).
