Earth Hour in 2009
WWF’s Earth Hour 2009 was a massive global phenomenon.
Our thanks to the millions of people around the world who switched off their lights for one hour on Saturday 28 March – you sent a dramatic visual signal to world leaders that they must take urgent action on climate change. This awe-inspiring event kickstarted our efforts to secure a strong ‘global deal’ at the Copenhagen UN climate summit in December.
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.
WWF's Earth Hour 2009 kicked off at 8.30pm in the Pacific islands and New Zealand, and took the world by storm as it travelled east to west. We compiled some of the many highlights from around the world as they happened...
