Abstract Many actors are involved in the urban freight delivery system. They hold different visions, perceptions, goals. However, city logistics affects a well-defined set of subjects: their acceptance of (and even positive contribution to) policy can be enhanced by continuing consultation. This evidence stresses the need for the stakeholders' engagement as a strategic factor of any decision-making process. The paper presents the guidelines of the EU-funded project SULPiTER (Interreg Central Europe Programme) for the stakeholders' involvement (both public and private) in the definition of city logistics policies. In particular, the FQP (Freight Quality Partnership) tool is analyzed and discussed. After an overview of the institutional references and the implemented experiences, a methodological approach is presented, describing the steps for an effective FQP implementation. The case of the Metropolitan city of Bologna is presented as the local application of the SULPiTER methodology, considering two aspects: the way of defining the governance for combining horizontally different public authorities, and the tool for e ngaging the private stakeholders in the definition of Sustainable Urban Logistics Plans (SULPs)
