Greeting by Federal Minister Klara Geywitz

“Green facades and roofs are an important contribution to increasing the quality of life in our cities and communities. They cool in summer and warm in winter, improve the microclimate and air quality, store rainwater and CO2 and assist in saving energy. For plants and animals they are a valuable habitat and for many people - including me - they are an indispensable piece of urban nature.

At the same time, building greening plays an important role in adapting our urban environment to climate change. Heat, drought, heavy rain or floods - cities and communities worldwide have to adapt to profound changes. At the same time, they must transform their infrastructure and building stock for a climate-neutral and sustainable future.

This year’s World Green Infrastructure Congress will strengthen the importance of roof, facade and interior greening for the climate-friendly transformation of cities and communities and further embed it in public awareness. I would like to thank the German Association of Building Greening “Bundesverband GebäudeGrün” with its national and international partners for making this important congress possible. I wish its visitors exciting encounters, stimulating expert discussions and inspiring excursions. See you in Berlin in June!”
