Coalition for Sustainable Cities & Regions

Mission Statement


  • Drawing on an expert- and practitioner-led process, the Communitas Coalition seeks to:
  • (1) Advance sustainable urbanization as a key component of the future UN Development Agenda, its Goals, tools, means of implementation and partnerships;
  • (2) Contribute to the technical development of an urban Goal with targets related to the economic, social, environmental, spatial and cultural dimensions of sustainable development and a basket of relevant indicators;
  • (3) Ensure the presence, as appropriate, of an urban dimension in the final set of SDGs.

  • On the one hand, Communitas provides expert- and practitioner-led technical input into the UN intergovernmental process. On the other, it gathers a wide multi-stakeholder coalition of organizations keen on advancing sustainable urbanization as a key component of the new UN Development Agenda, particularly in the horizon of Habitat III in 2016.
