The Association of Flemish Cities and Municipalities (VVSG) is the umbrella organisation of local governments in Flanders. VVSG provides consulting, training, coaching and lobby work for all 300 Flemish municipalities. Within VVSG, the International Team works on issues like local global policy, international cooperation and the local implementation of the Agenda 2030. In a 3-year pilot trajectory and together with a group of 20 municipalities, the International Team explores methods to structurally integrate the SDGs into municipal policy making. The Week of the Sustainable Municipality is a result of this intensive and participative trajectory.
