March 31: Earth Hour 2012

On Saturday, March 31, people around the world will turn off their lights from 8:30 to 9:30 p.m. to celebrate Earth Hour 2012. Sponsored by WWF (the World Wide Fund for Nature), Earth Hour is intended to make a global statement about climate change and to demonstrate a commitment to finding solutions. It also challenges participants to go “beyond the hour” and commit to further ongoing action to address climate change.

The lights-out initiative, which began in 2007 in Sydney, Australia, as a one-city environmental campaign, has evolved into a global sustainability movement. Last year, hundreds of millions of people participated in Earth Hour, which involved 5200 cities in 135 countries worldwide.

We invite everyone to join in celebrating Earth Hour 2012. You can sign up to participate in Earth Hour at or simply join millions of people throughout the world by turning off your lights on March 31 from 8:30 to 9:30 p.m. local time.

Thank you for all that you are doing to counter climate change and create a sustainable future!
