Franco-German climate action partnership: citizens identify urban heat and cool islands
At the beginning of October, a delegation from Climate Alliance member Worms visited its French partner city Eurométropole Metz to jointly present the results of citizen participation in mapping perceived urban heat and cool islands in both cities. The mapping of the two cities revealed many similarities: public squares, streets and car parks heat up more quickly in the summer. Citizens avoid staying there due to a lack of shade and ventilation as well as heated surfaces. On the contrary, the cool islands provide shade through trees, cool air through evaporation, proximity to water as well as good ventilation and seating opportunities.
The results also show that it is important to prioritise the following three approaches in order to reduce heat: Green structures through vegetation or trees, white structures through light and radiating surfaces and blue structures through the proximity of flowing water.
The project was implemented with the financial support of the Franco-German Citizen Fund. Since 2016, the cities of Worms and the Eurométropole Metz have been cooperating on the topics of climate action and adaptation. Supported by the TANDEM project, which is coordinated by Climate Alliance and Energy Cities, both cities have already carried out a variety of successful actions within the framework of this cross-border climate action partnership.
