This deliverable aims at initiating a reflection on how citizen science (CS) can become a science communication tool with potential to tackle misinformation. For this we envisioned to open the discussion with the CS projects enrolled in NEWSERA as pilots, as well as, bring both research and practice experts to enrich the debate and open a new direction in this matter of timely global concern. The reflection process will have two main objectives: i) better understand the nature of misinformation; ii) identify the present and future role of citizen science in this important subject of ethics related to communication. Two workshops were organized and tested with the collaboration of the NEWSERA pilots and invited experts. The content and results are hereby described. Citizens involved in CS projects become important data collectors and producers and can play a key role when it comes to science information and education. In this deliverable we analyze the way that CS projects can contribute to tackling one of the main problems we face nowadays in science communication: misinformation. After a comprehensive reflection on the matter, in a co-creation process with the NEWSERA pilots, partners and other stakeholders such as H2020 SwafS-19 sister projects (for instance, TRESCA and ENJOI) and communication experts, we provide as a main output a set of take-away ideas on how to use data and information in CS projects to help tackling misinformation.
