CC-DEMOS has recently initiated an in-depth and interdisciplinary study on the impacts of citizen engagement in policymaking. The study consists of various research and collaborative activities, and will be followed by a comprehensive report crafted to support practitioners, academics and policymakers in their efforts to create policy impact by using participatory methods. As a launching event, a first collaborative workshop on citizen engagement impacts has taken place on 21st June 2023. The event has welcomed a variety of participants interested in contributing the discussion on the multiplicity of impacts that citizen engagement has across Europe and beyond. The participants, who represented both academia and the European Commission, were ask to share their stories on impacts and reflect on such questions as how to frame, define and identify the most important areas in which the impact has been taking place. This mapping exercise on the impacts of citizen engagement has led to some initial conclusions that citizen engagement is an effective tool for shaping policy process in case of particularly complex policy issues that require innovatory approach, contextual knowledge and are multi stakeholder orientated. Also, citizen engagement is deemed as a general tool for improving the quality of democracy.
