Every year, on the last Saturday of March, Earth Hour is a call to the people of the world to take action to help protect nature and the climate. It involves switching off the lights for an hour or making any other tangible gesture to help the planet.

For one hour, all over the world, major landmarks like the Eiffel Tower in Paris and the Jet d’eau in Geneva go dark. On Saturday, 25 March 2023, CERN’s Globe of Science and Innovation was also plunged into darkness from 8.30 p.m. to 9.30 p.m

“Earth Hour is a powerful reminder that the environment is precious and that we must protect it. That’s why CERN takes part. We strive to minimise our own environmental impact and to identify technologies among those we develop that can make a positive contribution to a sustainable future,” says Charlotte Lindberg Warakaulle, CERN Director for International Relations.

Launched in 2007, the Earth Hour, organised by WWF, is one of the biggest global campaigns for climate and environmental protection. Thousands of towns, cities and businesses in over 190 countries have joined the movement.
