Earth Hour 2014: Switch off your lights on March 29

Switch off your lights on Saturday, March 29, from 20h30 to 21h30 local time and save the planet.

Every year in March since 2007, the World Wide Fund for Nature (WWF) celebrates Earth Hour, where millions of people, businesses and governments – including the European Union institutions – around the world turn off their lights for one hour, sending a powerful message for action on climate change.
