Earth Hour 2023 Unites the World in Darkness for Climate Action

Earth Hour 2023 will mark its 20th anniversary this weekend. The global event encourages millions to switch off lights for one hour in support of climate action and biodiversity. From private homes to famous landmarks, participants will take part in a symbolic gesture for the planet. The campaign began two decades ago as a call to protect nature and combat climate change. Since then, it has grown into a worldwide movement. This year, thousands of cities, businesses, and individuals will join in by turning off non-essential lights at 8:30 p.m. local time on Saturday.

Switzerland will take part, with cities, schools, and companies dimming their lights. WWF Switzerland's CEO, Thomas Vellacott, highlighted the link between nature conservation and human health. He stressed that protecting ecosystems is vital for a sustainable future. The event remains a simple yet powerful act. By switching off lights for 60 minutes, participants show their commitment to a healthier planet. No complex measures are required—just a shared moment of awareness.

Earth Hour 2023 will see Switzerland and many other nations unite in darkness for an hour. The annual event continues to raise awareness about environmental challenges. Organisers hope this year's participation will reinforce global efforts to safeguard nature and reduce carbon footprints.
