Despite recent efforts to improve the environmental performance of public investments in Italy, more needs to be done for the country to ensure a widespread adoption of green infrastructure (GI) planning across the national territory. This chapter provides a detailed overview of how GI and nature-based solutions (NbS) are currently implemented in Italy. It outlines the main policies, strategies, laws, and planning instruments relevant for GI and NbS and identifies the main actors responsible for infrastructure planning and implementation. At the project-level, the chapter looks at the different tools in place to integrate environmental considerations in infrastructure planning and appraisal, as well as in the financing and delivery of public investment projects. The chapter includes the analysis of four case studies in Italy, which highlight good practices and main areas for improvement to mainstream GI and NbS implementation.
