Earth Hour turns 20 as millions unite for climate action this weekend

Millions of people around the world will mark Earth Hour this weekend by switching off their lights. The global event, now in its 20th year, encourages cities, businesses and individuals to take part in a symbolic hour of darkness. Switzerland will join the campaign, with landmarks and households dimming their lights to support climate action and nature conservation. Earth Hour begins this Saturday at 8:30 p.m. local time. For sixty minutes, participants will turn off non-essential lights as a gesture of solidarity for the planet. The initiative, launched two decades ago, has grown into a worldwide movement for climate protection and biodiversity.

In Switzerland, hotels under the **Leonardo Hotel Group** will take part by dimming lights across their properties. Cities, municipalities, schools and businesses have also pledged to join. WWF Switzerland CEO Thomas Vellacott has highlighted the event's role in raising awareness about nature's vital role in human well-being. Thousands of cities and countless companies globally will participate. While no other Swiss landmarks have been officially named, the collective effort aims to send a clear message about the need for environmental action.

The 20th anniversary of Earth Hour celebrates two decades of global commitment to sustainability. This year's event will see Switzerland, alongside millions worldwide, briefly darken its lights. The action serves as a reminder of ongoing efforts to protect nature and combat climate change.
