Join Earth Hour 2013
March 18 2013
Join millions of people from around the world in the largest environmental event in history and go dark by switching off your lights from 8:30 p.m. to 9:30 p.m. on Saturday 23 March for Earth Hour.
In 2012, more than 6,700 cities and towns in 152 countries switched off their lights for Earth Hour sending a powerful message for action on climate change.
It's more than switching off lights for one hour a year; it's about giving people a voice and working together to create a better future for the planet.
