Every year on the last Saturday in March, millions of people around the world take part in Earth Hour and switch off their lights to show their support for our planet. Earth Hour is also celebrated in Berlin: At 8:30 p.m. sharp, the lights go out for one hour in many places.

Earth Hour is an open action and we welcome everyone to join in and help amplify our mission to unite people to protect our planet.
In Berlin, the lights will be turned off on Saturday 27 March 2021 at the following buildings, among others, from 20:30 to 21:30:
- Berlin Rathaus
- Brandenburg Gate
- Schloss Britz
- Rathaus Treptow
- Rathaus Köpenick
- Rathaus Spandau
- and several buildings owned by private companies.

Earth Hour was launched in 2007 by WWF and its partners as a symbolic lights-out event in Sydney and is now one of the world's largest grassroots movements for the environment.But Earth Hour goes far beyond the symbolic action of switching off - it has become a catalyst for positive environmental impact, driving important legislative change by harnessing people power and collective action.
