Earth Hour

On 26 March, it was once again 'Lights out for a peaceful and living planet!' in all of KfW's larger building units in Frankfurt, Berlin, Bonn and Cologne. As a responsible bank, KfW participated for the twelfth time in the worldwide Earth Hour, which was launched by the World Wildlife Fund For Nature (WWF) in 2007.

For this purpose, the lights will be switched off for one hour at all the above-mentioned locations between 8:30 and 9:30 pm. In view of war, the climate crisis and our dependence on fossil fuels, the signal sent out by Earth Hour is more important than ever. It is the largest peaceful climate protection and environmental action in the world. It stands for bringing people together across borders to protect our Earth.

"Climate action remains the key task for the future. The most recent report of the IPCC (Intergovernmental Panel on Climate Change) demonstrated this once again in a very important way. As KfW, we have repeatedly accompanied disruptive challenges. In this decade, too, we want to make an effective contribution to ensuring that the transformation of the economy and society succeeds", explains Stefan Wintels, CEO of KfW.

It all began 15 years ago in the Australian metropolis of Sydney. More than 2.2 million Australian households took part in the first Earth Hour on 31 March 2007 and switched off the lights at home for one hour to set an example for climate protection. One year later, Earth Hour reached 370 cities in 35 countries across 18 time zones. In the meantime, Earth Hour has become the largest global climate and environmental protection campaign worldwide. In Germany, more than 650 cities and over 750 companies have signed up again this year.
