It started with a question: How can we inspire people to take action on climate change?
The answer: Ask the people of Sydney to turn off their lights for one hour.
About Earth Hour On March 31 2007, for one hour, Sydney made a powerful statement about the greatest contributor to global warming – coal-fired electricity – by turning off its lights. Over 2.2 million Sydney residents and over 2,100 businesses switched off, leading to a 10.2% energy reduction across the city. What began as one city taking a stand against global warming caught the attention of the world. If the greenhouse reduction achieved in the Sydney CBD during Earth Hour was sustained for a year, it would be equivalent to taking 48,616 cars off the road for a year.
With Sydney icons like the Harbour Bridge and Opera House turning their lights off, and unique events such as weddings by candlelight, the world took notice. Inspired by the collective effort of millions of Sydneysiders, many major global cities are joining Earth Hour in 2008, turning a symbolic event into a global movement.
On 8PM March 29th, 24 global cities will participate in the Earth Hour, with over 13,000 businesses joining in, to turn off the lights. Imagine all 24 cities will be in darkness for 1 hour, only lid by candles by everyone.
Almost 200,000 had signed up for Earth Hour, so what are you waiting for? Sign up for the Earth Hour, and help to make a significant change on this world. But don’t just only sign up, remember to do your part!
