Cities are getting hotter: the 10 essential green infrastructure solutions needed to combat the urban heat island effect

Trees, parks, green roofs and permeable surfaces can significantly reduce urban temperatures, improving comfort, health and quality of life during the summer months.

During summer, temperatures in most urban areas are reaching extreme levels more frequently, creating hot, humid and increasingly uncomfortable living conditions. Climate change, rising global temperatures and the growing frequency of heatwaves are all contributing to the overheating of cities, particularly in densely built-up areas dominated by concrete and tarmac.

Tarmac, concrete and other impermeable surfaces absorb large amounts of solar energy during the day, helping to keep temperatures high well into the night.

The consequences affect public health, quality of life and energy consumption. Heatwaves increase the risk of heat-related illnesses and respiratory problems, while keeping buildings cool requires vast amounts of energy, especially in densely populated neighbourhoods with older, poorly insulated properties.

Against this backdrop, urban greenery is becoming increasingly important. Trees and vegetation are no longer seen as purely decorative features but as essential climate infrastructure capable of transforming the urban microclimate.

What is the urban heat island effect?

The urban heat island effect refers to the increase in temperatures within cities compared with the surrounding countryside. The main cause is the widespread presence of artificial surfaces such as tarmac, concrete and rooftops, all of which absorb solar energy and release heat slowly into the surrounding environment.

Vegetation behaves very differently. Trees, lawns and green spaces provide shade, reduce the overheating of surfaces and
