NEWSERA is a project funded by the European Commission that analyses the complex and multidirectional science communication strategies by addressing the quadruple helix stakeholders in citizen science projects as the new paradigm for science communication. The aim of NEWSERA is to show the virtues of citizen science as an inclusive, broad and powerful science communication mechanism that can increase trust in science communication while opening up science and innovation to society, raising awareness and reducing the chances of incurring in fake news by means of promoting critical thinking. For this purpose, NEWSERA set up a series of workshops on communication for citizen science projects, the #CitSciComm Labs, that involve representatives from citizen science projects, science communicators, science and data journalists, quadruple helix stakeholders (citizens, academia scientists, policy makers, industries and SMEs): together they collaborate on new and improved strategies of communication to help citizen science projects reach different stakeholders and face new challenges, within the evolving relationship between science and society. Each Lab consists of a series of co-creation workshops that are being organised in Spain, Portugal and Italy, allowing for participation and mutual learning. Building trust among citizens and institutions is still a great challenge. In modern democracies, public institutions need to be close to citizens, to increase their legitimacy, accountability and good governance.In addition, there are many citizens who would like to be actively involved in the policymaking process. Increasingly, policy makers are turning towards citizen science as a way to engage with their citizens and gather evidence for science-informed policies, in order to face the 21 century challenges, including planetary health. In this poster, we will present the Policy Brief that has been developed after the second round of #CitSciComm Labs, addressing the challenges that citizen science initiatives may face when reaching out to Policy-Makers, as well as pinpointing innovative ideas to overcome difficulties and adapt to a changing science communication environment.
