The socio-economic impact assessment of the GreenSCENT project, detailed in this deliverable, employs adual perspective. It quantifies the impact on stakeholders, public administrations, schools, and local authoritiesresulting from the adoption of GreenSCENT solutions. Additionally, it maps the impact of GreenSCENTactivities to analyse how the solutions and activities developed by the project enhance users' conditions duringthe project's development and beyond.The assessment methodology is both qualitative and quantitative, multi-stakeholder, and multidimensional,using the impact value chain method to analyse project inputs, activities, outputs, outcomes, and impacts. Thisapproach supports the identification of the project’s value proposition, its expected impacts, and potentialobstacles to full achievement.To respect the uniqueness of each project’s pilot, the methodology is modular, adaptable to different settingsof the demonstrations and pilots. Project partners were actively involved in the methodology development, witha dedicated workshop early in the project to assist partners in understanding the process and providingnecessary information. The assessment was performed at the end of the project, with output and activitiesmonitored throughout the project's development to provide a mid-term assessment for the partners to adjusttheir actions. The final impact assessment considers impacts on a larger scale and takes into account theupscaling potential of the project.The GreenSCENT impact assessment framework draws inspiration from earlier projects related to citizenscience, such as the ACTION project and the MOTION handbook, focusing on transformative system change.The assessment covers five basic elements: scientific, social, environmental, economic, and political impacts.The results of the assessment highlight the project's added value, transformative capability, and the mostinteresting outcomes.The GreenSCENT project highlighted the crucial role of teachers and educational staff in implementingDemonstrators, emphasizing the need for pedagogical experts to create effective deployment strategies. Theinvolvement of class teachers, who understand classroom dynamics and student motivation, was essential.The project also underscored the importance of discovery and tangible outputs for students, although digitaltools sometimes posed challenges. The presence of experts in classrooms significantly boosted studententhusiasm and motivation.Despite challenges, the Demonstrators positively impacted students by increasing interest in science-relatedtopics and encouraging lifestyle changes. The engagement methods were designed to be fair and motivating,with flexibility and inclusivity being key considerations. The Open Innovation Challenge attracted significantparticipation and could inspire younger students in future projects. The exploration of AI's impact onsustainability education revealed its potential benefits and challenges, highlighting the need for responsibleand balanced AI adoption.
