Patronage

Federal Minister for the Environment, Climate Action, Nature Conservation and Nuclear Safety

„Germany needs public and private greening of all kinds. This can be anything from rewilded gardens, urban parks and open areas to greened roofs and façades. You are truly a multi-talented group of people. That is why I was delighted to become patron of the World Congress of Building Greening.

Green plants help to cool our concrete cities, act as a buffer against heavy rain, improve air quality and make our lives healthier. Now we need to ensure that people experience these benefits first hand – starting at their own front doors.

My Ministry promotes this goal with the Federal Action Plan on Nature based Solutions for Climate and Biodiversity. For example, the Action Plan supports local authorities that want more green instead of concrete. That is a win for climate action, public health and precautions against extreme weather events. And it makes our towns and cities attractive and liveable – now and in the future."


Ute Bonde
Senator for Mobility, Transport, Climate Protection and the
Environment

„Berlin has long been a pioneer in innovation, sustainability, and climate-oriented urban development.
The greening of our buildings and public spaces plays a central role in this – it makes our city more resilient, livable, and beautiful.

Green roofs and facades improve the urban climate, promote biodiversity, filter air pollutants, mitigate the risk of heavy rain, and create new habitats – for people as well as animals. In a growing metropolis like Berlin, this potential is invaluable. Building greening is not just an aesthetic extra, but an effective tool for climate adaptation.

As the capital, we want to set impulses for a holistic, nature-based urban planning that connects ecological and social quality of life. With our state-owned funding program „GründachPLUS“, we have been supporting Berliners, companies, and initiatives in the green transformation of their existing buildings – financially and advisory – since 2019.

The World Congress on Building Greening brings together experts, practitioners, and decision-makers from all over the world to exchange knowledge, experiences, and best practice examples. In Berlin, they will encounter many inspiring projects and committed actors.

I cordially invite all Berliners, partners, and interested parties to participate in this significant congress and to jointly develop ideas for a greener, climate-adapted future.“
