Earth Hour at the OpernTurm – together for greater climate protectio

March 2023

Earth Hour is taking place once again on March 25, 2023, from 8.30 to 9.30 p.m., and the OpernTurm will join innumerable private households, public buildings, and prominent structures in turning off the lights.


Back in 2007, 2.2 million households in Sydney turned off their lights for one hour for the first time. Earth Hour was born. Today, the initiative launched by WWF is the world’s largest climate and environmental protection campaign. Every year on the last Saturday in March, countless people, cities, communities, and companies around the globe join together to send a clear signal for greater climate protection and responsible use of resources. OpernTurm has been participating in the campaign for six years now.


With the goal of creating the “Biggest Hour for Earth,” this time round the initiative seeks to encourage us to use Earth Hour to also take some time out from our daily routines and distractions and instead to spend 60 minutes doing something positive for the planet and our environment – so that one single “Earth Hour” becomes millions of hours for the Earth. Everyone can join in.


Make a statement with the OpernTurm on Saturday evening – together for greater climate protection.
