City Campaign. Developing a 15-Minute City. Cagliari, Perugia, Pisa, Trieste

• To engage urban planners, municipal managers, and local community organizations in Cagliari, Perugia, Pisa, and Trieste to recognize disparities in access to essential services.

• Bring together citizens, transport authorities, and neighborhood associations to explore which districts meet “15-minute city” criteria and which are underserved.

• Encourage dialogue through simple maps, short reports, and local workshops highlighting gaps in walkable service coverage.

• Invite municipalities to adopt non-binding “15-Minute Access Snapshots,” sharing concise metrics on proximity and diversity of essential services in each district.

• Encourage local actors to post brief visual summaries online and track improvements over time.

• Promote replication by enabling other cities or neighborhoods to apply the same indicators, document progress, and share lessons learned for equitable urban planning.
