WWF's Earth Hour 2009

Join the more than 500 cities worldwide and turn off your lights on March 28th for one full hour in a global demand for action on climate change. Governments won't act unless they see consensus in the people.

Earth Hour

“Earth Hour is an opportunity for every man, woman and child from all corners of the globe to come together with a united voice and make a loud and powerful statement on the issue of climate change,”- Archbishop Desmond Tutu

“The C40 Climate Leadership Group is about cities working together to drive down greenhouse gas emissions and that is why as Chair of the C40, I support Earth Hour. It's crucial that cities and the public come together to take action against climate change and Earth Hour provides a great platform to do that."- Mr David Miller, Mayor of Toronto and chair of the C40 Large Cities Climate Leadership Group
