Within five key themes we try, along with the city authorities, to find the best solutions for the future security of Copenhagen, based on the complex challenges the city faces. We identify and coordinate smart city-needs in the municipality’s departments and match them with existing knowledge and solutions on the market. In this way, Copenhagen Solutions Lab acts as a bridge between external partners and Copenhagen Municipality’s initiatives concerning smart city. Through collaborations with the research community and the market, from the small and innovative actors to the large and society-carrying, Copenhagen Municipality access the innovation power that is needed to create new and effective urban solutions.
