Cities can be several degrees hotter than surrounding rural areas. This is the urban heat island effect โ and the way we build our cities plays a major role.
๐๏ธ What drives urban heat?
โข Less greenery: Fewer trees mean less shade and natural cooling.
โข Heat-trapping materials: Asphalt and concrete absorb heat during the day and release it later.
โข Dense buildings: Urban layouts can restrict airflow and trap warmth.
โข Human activity: Vehicles, air conditioning systems and industrial operations add waste heat to the environment.
The consequences go beyond discomfort. Extreme urban heat can increase energy demand, worsen air quality, threaten public health and disproportionately affect vulnerable communities.
๐ฑ The solutions are within reach.
More urban trees, green roofs, reflective surfaces, better building design and thoughtfully planned public spaces can help cities stay cooler and more resilient.
The future of sustainable cities isn’t just about reducing emissions โ it’s also about adapting the places where millions of people live, work and move every day.
A cooler city is a healthier, more resilient city.
