Earth Hour 2026
Flip the switch on Saturday, 28 March
Mark your calendars: The ‘biggest hour for Earth’ is back
On Saturday, 28 March 2026, between 20:30 and 21:30, people around the world will take part in Earth Hour 2026. The idea is simple: Turning off non-essential lights for one hour. The message: Protect our planet.
What is Earth Hour?
The initiative was started in 2007 by the World Wildlife Fund (WWF), as a symbolic ‘lights off’ moment. Today it is a global movement. With millions of people across more than 118 countries and territories participating every year, it has become a catalyst for environmental change.
How can I get involved?
The WWF invites everyone to reconnect with the world around you:
- Cook a sustainable, eco-friendly dinner.
- Enjoy some quality ‘unplugged’ time with your friends or family.
- Listen to the official Earth Hour Spotify playlist.
- Calculate your personal carbon footprint.
Whether it is fitness, art or being outdoors, anyone can take part.
Does one hour really make a difference?
It does – because supporters around the world act together. When lights go off during the ‘biggest hour for Earth’, it sets a global spotlight on climate change and the need to work together to keep our future bright.
The Hellenic Industrial Property Organisation (OBI) participates in «Earth Hour» initiative, turning off non-essential lights for one hour in both premises in Paradissos Amaroussiou and in Athens.
Remember: Every day can be Earth Day. So why not find more ways that help the planet – while doing something you enjoy?
