Compact cities have lower carbon emissions, but poorer air quality, less green space and higher mortality rates

A study by ISGlobal analyzed 919 European cities, identifying four urban configurations: compact-high density, open lowrise-medium density, open lowrise-low density, and green-low density. Compact high-density cities have lower carbon footprints but higher mortality rates due to poorer air quality and less green space.
