After more than two years of constructive cooperation, the twelve partnerships from the pilot phase of the project 'Municipal Partnerships for Sustainability' met for the results conference in Belgrade from 28 to 30 November 2018. The German cities and municipalities and their partner municipalities from South-East Europe looked together at their successfully implemented measures and forged new plans for the future. Through the municipal partnerships, municipalities support each other in implementing the Sustainable Development Goals and share their experiences and approaches.
