With only one day to go, Earth Hour 2011 is set to break the record books, with over 131 countries ready to switch-off the lights this Saturday March 26 at 8.30pm.

Earth Hour began in 2007 through a partnership between WWF Australia, Leo Burnett and Fairfax Media, when 2 million Sydney-siders switched off their lights for one hour. By 2010, Earth Hour had created history as the largest voluntary action ever witnessed with participation across 128 countries and every continent. Among the participating venues were some of the world’s most recognised man-made marvels and natural wonders, including the Eiffel Tower, Niagara Falls, The Golden Gate Bridge and many more.
Now Earth Hour 2011 promises to break the record books again. 131 countries and territories have already registered to take part, and many global organisations are set to join hundreds of millions of repeat participants.
“It is only through the collective action of business, organisations, individuals, communities and governments that we will be able to affect change on the scale required to address the environmental challenges we face,” said Andy Ridley, Co-Founder and Executive Director of Earth Hour.
This year marks the beginning of a new phase for Earth Hour – beyond the hour – where participants are asked to use the event as an opportunity to commit to an additional action, big or small, that they will sustain for the future of our planet. Among the thousands of cities taking part in Earth Hour 2011, many have already committed to taking action beyond the hour, including:
• Sydney, Australia where actions include switching to LED lights in parks and streets,
• Medellin, Colombia where long term water protection and tree planting initiatives form part of their commitment, and
• Shenyang, China where 38,000 hectares of land will be reforested.
