Earth Hour is a global World Wildlife Fund (WWF) climate change initiative. Individuals, businesses, governments and communities are invited to turn out their lights for one hour on March 28, 2009 at 8:30 p.m.-9:30 p.m. to show their support for action on climate change.
Other cities that committed include Moscow, Los Angeles, Las Vegas, London, Hong Kong, Sydney, Rome, Oslo, Cape Town, Warsaw, Lisbon, Singapore, Istanbul, Mexico City, Toronto, Dubai and Copenhagen.
The extensive WWF conservation network also has more than 30 teams working in countries such as India, Spain, Switzerland, France and the Philippines ready to support a local Earth Hour roll out.
"It aims to demonstrate unprecedented solidarity and provide a visual global mandate that will put the heat on world leaders meeting in Copenhagen in December 2009 to strike a new global deal on climate change," WWF said.
"When leaders gather in Copenhagen in December 2009 to negotiate a new deal on climate they must feel that the eyes of the world are upon them. Earth Hour provides an opportunity for the public to send a powerful signal that they are watching and expect action," WWF International Director General Jim Leape said.
"We believe that Filipinos can unite when driven by the common good:
Manny Pacquiao's fights attest to this. The growing realization for the need to act on climate change, coupled with the success of Earth Hour Philippines last March provides us with a springboard to launch a bigger and better campaign next year. On 28 March 2009 we aim to enjoin 10 million Filipinos to join the fight against climate change by simply turning off their lights," added WWF-Philippines Climate Change and Energy Programme Head Yeb Saño.
"The climate movement is in full-swing. Earth Hour is our best chance to meet the challenge with unity and purpose," Saño said.
David Miller, Mayor of Toronto and chair of the C40 Large Cities Climate Leadership Group said the C40 Climate Leadership Group is about cities working together to drive down greenhouse gas emissions.
"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 just that," he said.
Earth Hour Global Executive Director Andy Ridley adds that 2009 is the planet's "destiny year" with critical decisions needed to be made at the Copenhagen meeting on reducing greenhouse gas emissions.
"2009 is the year we decide the future of the earth. It is the year the world finally agrees on a plan to massively reduce carbon emissions across the globe. This is the time to invest in new ways of doing business in a new low-carbon economy. The sum of our actions today can change history and secure the future of our planet," he said.
