Italy is building the foundations of its national platform through collaboration among cities, institutional support and a set of shared technical spaces. This process can be traced back to the selection of nine Italian cities under the EU Mission framework in 2022. It continued through the Let’sGOv Pilot Project within NetZeroCities and has gradually evolved into a community of practice connecting cities, national networks and different ministerial actors. Rather than a closed formal structure, what is emerging is an operational ecosystem that is beginning to lay the groundwork for a future national platform that is both stable and tangible.
