Our project aims to strengthen meaningful youth participation in shaping responsible consumption practices in Trnava. While young people are daily consumers, they are rarely involved in local sustainability discussions. The project will engage 25 young people aged 16–25 in a 12-month participatory process where they analyse local consumption patterns, design youth-led initiatives and engage in structured dialogue with decision-makers. The objectives are to increase knowledge of circular economy, strengthen civic competences, implement at least four youth-led initiatives and develop a Youth Recommendation Document for the municipality.
