The Strategic Plan of the Single SEZ is governed by Article 11 of Decree-Law No. 124 of September 19, 2023, coordinated with Conversion Law No. 162 of November 13, 2023.

The Plan has a three-year duration and defines,  in line with the National Recovery and Resilience Plan (NRRP) , with national and regional programming of European structural funds, and in compliance with the principles of environmental sustainability, the development policy of the Single SEZ. The plan identifies, also in a differentiated manner, for the regions that are part of it, the sectors to be promoted and those to be strengthened, the priority investments and interventions for the development of the Single SEZ, including those intended to encourage industrial reconversion aimed at supporting energy transition, and the methods of implementation.

Three representatives jointly designated by the Union of the Provinces of Italy (UPI) and the National Association of Italian Municipalities (ANCI) , also participate in the preparation of the Plan.

The Plan is approved by Prime Ministerial Decree, upon the proposal of the Minister for European Affairs, the South, cohesion policies and the NRRP , in agreement with the Minister of Economy and Finance, the Minister of Infrastructure and Transport, the Minister of enterprises and Made in Italy and the Minister for Civil Protection and Maritime Policies, following the opinion of the Steering committee referred to in Article 10, paragraph 1.
