EU cities and heat extremes
Heatwaves are one of the most concerning consequences of climate change, with record-breaking temperatures becoming more frequent and intense, and projected to continue. Extreme heat is particularly alarming in cities, where it leads to the Urban Heat Island effect. This effect causes higher local temperatures and urban areas to become hotter than surrounding suburban regions and rural areas. This is connected to the presence of more sealed surfaces and higher density of both people and heat-emitting infrastructures. We need to rapidly reduce greenhouse gas emissions to limit climate change. At the same time, we should adapt by diminishing exposure and vulnerability and increasing the overall resilience and adaptive capacity of cities. The deployment of green and blue infrastructures is one of the most effective measures to counteract the urban heat island effect. However, the combination of several strategies adapted to the local circumstances is the most powerful. This policy brief focuses on how to tackle severe heat in cities and provides recommendations, best practices and analytical tools that can be used by local authorities.
