Despite recent efforts to promote sustainability considerations in public investment decisions, green infrastructure (GI) and nature-based solutions (NbS) are not yet fully integrated in spatial planning and projects’ appraisal instruments in Italy. For this reason, the OECD has developed a series of recommendations to promote the integration of GI and NbS in infrastructure governance in Italy. The recommendations build on international good practices and 3 main pillars: 1) creating an enabling policy and regulatory environment for the consideration and uptake of GI and NbS; 2) defining clear institutional roles and responsibilities, and establishing co-ordination mechanisms to boost collaboration among the actors responsible for GI planning and implementation of NbS; and 3) building a knowledge-base and technical competencies for planning and implementation of GI and NbS across all levels of government
