Advancing Urban and Extra-Urban Afforestation: A Case Study of the Italian National Urban Forestry Plan in the Metropolitan City of Genoa

Urban afforestation is a key strategy for combating climate change and enhancing urban living by reducing carbon emissions and improving air quality. Reflecting these priorities, Italy’s National Ecological Transition Plan (NETP), led by the Ministry of Ecological Transition (MiTE), introduced the National Urban Forestry Plan to accelerate sustainability and resilience in urban areas. This plan focuses on reducing carbon emissions, enhancing natural capital through reforestation, and promoting Nature-Based Solutions (NBS) for climate adaptation. Our study aligns with this framework by exploring how local urban forestry initiatives support the NETP’s objectives, providing a concrete example of policy implementation. Genoa (Italy) serves as a compelling case study. In 2023, the city received PNRR funding under the “Protection and Enhancement of Urban and Extra-Urban Greenery” initiative to improve air quality, restore biodiversity, and strengthen ecological corridors. Our research identifies three key areas for improvement: ecological planning, citizen engagement, and impact monitoring. We present initial findings and quantitative data, evaluating CO2 sequestration potential, communication strategies, and consider the strengths and weaknesses of the specific context. These findings highlight the need for further investigation to optimize and communicate urban greening efforts.
