More than 5,200 cities and towns in 135 countries worldwide switched off their lights for Earth Hour 2011 alone, sending a powerful message for action on climate change. In 2012, a new record was set, with 150 countries and territories across 6,494 towns and cities around the world.
In Berlin, the Brandenburg Gate, the Television Tower and the Red City Hall went completely dark for one hour from 8:30pm – 9:30pm on Saturday 31.03.2012. As part of the event, a map of the world was created by the WWF, using hundreds of colored-paper-surrounded tealights in front of the Brandenburg Gate. In addition, lanterns designed like the earth were handed out to the audience.
