Following intense summer heatwaves in 2026, various European cities and regions have begun implementing urban cooling and heat protection strategies.

In Belgium and France, efforts have focused on urban planning and community support. Namur, Belgium, launched a ‘Plan Fraîcheur’ to map heat islands, increase vegetation, and protect vulnerable populations through a dedicated heatwave network. In the Var department of France, proposals include transitioning toward ‘sponge cities’ by replacing asphalt with permeable surfaces and creating ecological corridors. Meanwhile, in Aubervilliers, community groups have organized local solidarity efforts to distribute food and water.

In Germany and Austria, the focus has shifted toward protecting educational infrastructure and expanding municipal cooling initiatives. Salzburg is retrofitting classrooms with blinds and greenery while establishing new construction standards that include canopies, reduced glass surfaces, and external sun protection. Additionally, the city plans to utilize school rooftops for photovoltaic systems. Frankfurt is implementing a tiered strategy that prioritizes architectural design and passive cooling, such as nighttime ventilation and external shading, to manage indoor temperatures in schools and existing buildings. The city is also testing new technologies through pilot projects.

In Austria, Klagenfurt has launched the ‘Cool down Klagenfurt’ project. To finance this, 50 percent of parking fees collected in the Ostbucht area will be allocated to a permanent heat protection fund. This initiative aims to plant 1,000 trees by 2030, unseal paved surfaces, and install drinking water fountains and ‘Cool Spots’ in vacant buildings. In Linz, local representatives are advocating for improved urban planning in vulnerable districts, including repurposing a high-rise bunker as a cooling refuge.
