Earth Hour 2021: Raising people's awareness for climate protection

For the 13th time, the City of Bonn is participating in the annual worldwide Earth Hour climate protection campaign initiated by the environmental foundation World Wide Fund for Nature (WWF). To set an example against the waste of resources and for climate protection, the WWF calls for the 15th time to switch off the light for one hour.

On the day of action, Saturday, March 27, 2021, from 8:30 to 9:30 p.m., the lights will be switched off at well-known municipal buildings.

Mayor Katja Dörner hopes that many citizens will participate in the symbolic action. "Actions like Earth Hour are important to make even more people aware of climate protection. In Bonn, we as a city, but also numerous UN institutions and many other national and international organizations are committed to working on the issues of climate protection and sustainability. But if we want to stop the climate crisis, we all need to further intensify our joint efforts."

In the future, the City of Bonn will place a focus in climate protection on the area of renewable energies. To this end, the City Council has adopted a subsidy program for photovoltaic systems, a solar obligation subject to economic viability for new buildings, as well as a consulting offensive and exemplary projects for the city's own municipal buildings under the title "Solar Bonn". The climate-neutral city administration by the year 2035 is another decided building block on the way to achieving climate neutrality by the middle of the next decade.

Bonn takes part for the 13th time

For the 13th time, the city will extinguish the lighting at city halls, cultural sites and other municipal buildings. In addition, Stadtwerke Bonn will switch off the floodlights at numerous prominent buildings and monuments. The University of Bonn is also participating again.

UN Bonn, Deutsche Post and Deutsche Telekom join in

Deutsche Post DHL has agreed that the Post Tower will also remain dark. Deutsche Telekom will participate with its headquarters and office port on Friedrich-Ebert-Allee, the bridge over Bundesstrasse 9 and the T-Mobile building on Landgrabenweg. The United Nations is also supporting the campaign once again, which is why “Langer Eugen” on the UN Campus will remain dark. The Federal Ministry of Education and Research has also confirmed its participation.

Background: Earth Hour annual campaign

The Earth Hour campaign began in Sydney, Australia, in 2007 and quickly expanded into a global phenomenon. One year later, millions of people in 35 countries switched off their lights for one hour to set an example for climate protection. In 2009, Bonn, Berlin and Hamburg were the first German cities to take part in the international campaign.

Millions of people and countless cities from 190 countries worldwide took part in the last Earth Hour 2020. As for Germany, 373 cities, hundreds of companies and businesses, and thousands of private households took part in Earth Hour.
