The aim of this report is to investigate what aspects of the dialogue between city officials and private developers can be improved to increase the chance of circular initiatives making its way into the final building project. Based on interviews with private developers and their consultants as well as workshops with city planners from London, Copenhagen, Vantaa and Hamburg seven recommendations for an improved dialogue on circular economy with developers was extracted. The seven recommendations are a result of a thematic analysis with the premise of the recommendations being as straightforward as possible for the city officials in collaboration with developers to act upon. The recommendations are developed both as a standalone instrument and checklist to be used in all new private building projects, as well as points of attention to be integrated into existing instruments.
