The “ECOinfluencers: Art, Action, and Participation” project aims to empower young people as active agents of change in environmental sustainability and democratic participation. Its main objectives include fostering youth engagement in practical sustainability actions like reforestation and creative recycling; promoting sustainable urban art to raise awareness of responsible consumption and eco-anxiety; encouraging youth activism and civic education through debates, institutional visits, and the ECOinfluencers network; developing key skills in sustainability, digital communication, and leadership; supporting an international youth community through European cooperation; creating lasting social impact via strategic alliances with local and European institutions; and ensuring replication and sustainability of results. The project aligns with the EU agenda for sustainable development and the green transition.
