The debate on growth versus environment at the urban scale

The long-standing growth-versus-environment debate has centered on national and global scales, devoting little attention to cities despite steadily increasing urban concentrations of population, activities and emissions. This Perspective clarifies how this debate plays out for cities by relating four urban growth dimensions—economic, population, spatial and environmental—to the narratives of green growth, degrowth and post-growth. To this end, we review theoretical and empirical insights about links between growth dimensions. Specific issues addressed include horizontal spillovers among cities, vertical policy integration and local experiments. Thus we connect the abstract growth-versus-environment debate to evidence regarding urban environmental policy.
