Earth Hour lights the way...
The impact of WWF’s Earth Hour has been acknowledged by world leaders meeting for crucial climate talks this year.
On Saturday 28 March 2009, hundreds of millions of people across the planet switched off lights for one hour to send a visual and symbolic message to all those in power.
Earth Hour was a stunning start to our campaign to persuade global governments to agree on drastic cuts in greenhouse gas emissions, to minimise the effects of climate change - while there's still a chance.
During Earth Hour, iconic international landmarks like Sydney Opera House, the Acropolis, the Bird’s Nest stadium in China, the pyramids of Giza, the Eiffel Tower, the Empire State Building and Big Ben were all plunged into darkness for 60 minutes as part of the largest global action of its kind ever.
