🌡️Germany’s hottest city: Mannheim
According to the Heat Vulnerability Index of the Deutschen Umwelthilfe e.V (DUH), Stadt Mannheim ranks as the city where the most people are affected by summer heat. Here a particularly large share of residents are exposed to extreme conditions. ☀️
The city has been responding decisively for years:
🌳 In 2021, the city council adopted a Heat Action Plan: 1,000 new trees, new green islands & redesign of the station square.
💨 A fresh air corridor developed from the #Bundesgartenschau (BUGA) 2023 area now helps cool the city and shows how innovative planning can directly improve the microclimate.
🌿 An exemplary façade greening on Mannheim’s Planken added 113 m² of plants across 19 species, enhancing the pedestrian zone while improving the microclimate through water storage and evaporation.
🏢 The Sparkasse Rhein Neckar Nord is transforming its new downtown branch with a 300 m² green façade, a green roof terrace, heat pumps, photovoltaics, and a cistern irrigation system
🤝 At the first #Begrünungsforum in 2025, organized under the #LocalGreenDeal, more than 100 experts from business, academia, and administration discussed solutions like green roofs with solar, biodiversity, and the “sponge city” principle.
Mannheim shows: greening, de-sealing, and innovative construction concepts are not “nice-to-have” projects but a matter of survival. Urban spaces need to become innovative, sustainable, and climate-resilient! ♻️
