Designing greener cities is not simply an environmental ambition, but a practical urban priority tied to resilience, public health, and quality of life. This session explores how cities are moving from vision to implementation through parks, urban forests, green corridors, and other nature-based solutions, while addressing the governance, financing, and delivery challenges that often shape their impact. Bringing together case-based experiences, the discussion will look at what is working, how cities are embedding green infrastructure into broader urban strategies, and what it takes to scale these interventions in ways that deliver tangible benefits for both people and the urban environment.
