Around 75% of Europeans live in cities, where higher population density and extensive commercial zones contribute to environmental and health challenges, such as air pollution and climate change effects like heat waves and flooding.

The European Environment Agency (EEA) reports that urban buildings account for 40% of energy use and 36% of greenhouse gas emissions in Europe, with most buildings being energy inefficient. 

Smart renovations can improve sustainability.

As populations age, cities need adaptable, energy-efficient buildings. Municipal governments play a key role in climate change mitigation, promoting green spaces, waste management, and circular economies.

The EEA supports nature-based solutions and effective urban planning for a sustainable future.
