Sport promotes social inclusion and sustainability in schools. This mixed-method study, conducted in a secondary school in Naples, examines the impact of an innovative sports program on inclusion and sense of belonging, aligned with the UN 2030 Agenda. A total of 100 students participated, with an experimental group engaging in cooperative sports and a control group following traditional physical education. Results showed improved peer collaboration and a 15% increase in belonging and 12% in inclusion in the experimental group. The study highlights the role of structured sports in fostering cohesion, well-being, and inclusive school communities.
