Thousands of cities and millions of people will again join the World Wildlife Fund (WWF) campaign in 20205 by switching lights off at the same time – as a sign for a living planet. In Leverkusen, in addition to the BayArena, the Water Tower and the Rathaus-Galerie will be in the dark to show combined support for climate and environmental protection.
The campaign aims to take a joint stand for environmental and climate protection. It’s an hour for the planet earth – hence the name Earth Hour. The campaign first started in Sydney on 31 March 2007. Now it’s the biggest global climate and environmental protection event worldwide. Further information is available from the WWF.
