We emphasize the importance of increasing the number of metropolitan regions, cities and towns that are implementing policies for sustainable urban planning and design in order to respond effectively to the expected growth of urban populations in the coming decades. We note that sustainable urban planning benefits from the involvement of multiple stakeholders as well as from full use of information and sex-disaggregated data, including on demographic trends, income distribution and informal settlements. We recognize the important role of municipal governments in setting a vision for sustainable cities, from the initiation of city planning through to revitalization of older cities and neighbourhoods, including by adopting energy efficiency programmes in building management and developing sustainable, locally appropriate transport systems. We further recognize the importance of mixed-use planning and of encouraging non-motorized mobility, including by promoting pedestrian and cycling infrastructures.
