Germany — Sponge cities — OECD: Germany’s sponge cities
Germany promotes nature-based solutions to advance climate adaptation in cities. By mimicking the natural water cycle, green roofs, green façades and other green spaces absorb rainwater where it falls—like a sponge—until it can infiltrate or evaporate.
This helps prevent flooding, cool buildings, support biodiversity, and improve air quality and wellbeing.
