‘GREEN NIGHT’ is the second experience of Tunisia (after the 'LiLa JemILA' project which has been granted the status of associated event during the last edition) in the European Researchers’ Night after being associated to H2020. A diverse team of experts in scientific research and science communication, from the research and innovation community along with Civil Society Organizations (CSO), have been gathered by the Tunisian Ministry of Higher Education and Scientific Research (MHESR) having the sole target of the organization of the Researcher's Night activities for the year 2020. Deeply aware that researchers are an integral part of the community and that their profession is both fun, challenging, interesting and worth pursuing, the MHESR has fixed as main objective of the project to bring them to the general public and to increase awareness of research and innovation activities specifically leading to a cleaner environment and a better quality of life. Key issues will be enhancing the public recognition of researchers' work, a better understanding of the impact of their work on citizen's daily life, and encouraging young people to embark on research careers developed to ensure real sustainability, zero pollution, affordable secure energy, smarter transport and high quality foods. To achieve these objectives the multi-sites GREEN NIGHT will be held in the Tunisian Science City (CST), the Monastir Science Palace (PSM) and the Science Village of Tataouine (VST), on the 25th September 2020 (starting during Friday afternoon and lasting till Saturday morning). A series of activities will be conducted before and during these events based on an eco-friendly model that will aim a ZERO pollution level by using a paperless approach, less plastic, less ink, less fossil fuels and reducing the amounts of waste generated.
