Earth Hour 2025 to Unite Global Communities with Lights Off and Voices Raised

The WWF-led initiative on March 22 will see landmarks and homes worldwide go dark for an hour, encouraging action on climate change and biodiversity loss.

• Earth Hour 2025 will take place on March 22 from 8:30 PM to 9:30 PM local time, with millions of participants in over 180 countries joining the symbolic action.
• This year's theme, 'Licht aus. Stimme an.' (Lights off. Voice on.), integrates public singing events to amplify messages on environmental protection.
• In Germany, nearly 100 municipalities in North Rhine-Westphalia, including Cologne, Essen, and Dortmund, will turn off lights at landmarks such as the Cologne Cathedral and Zeche Zollverein.
• The initiative aims to raise awareness about climate change, biodiversity loss, and light pollution, particularly in densely populated areas like the Ruhr region.
• WWF encourages individuals to participate by turning off lights at home and joining community events, emphasizing long-term behavioral change over immediate energy savings.
