The present deliverable serves as a first progress report of the ECS project, where we investigate the impact pathways of the project and its wider citizen science context, collect evidence for its outcomes, and learn how we can generate contributions at a wider societal level. It is based on a rich collection of quantitative and qualitative evaluation data that aim to demonstrate outputs, outcomes and first contributions to the achieved impacts across six impact areas: social/societal, political, scientific, institutional, technological, and economic. The data have been collected in close collaboration with all project partners, the ECS affiliated entities, and ECS ambassadors.
