Urban mobility is crucial to sustainable city development, bridging environmental preservation, economic advancement, and social equity. This paper investigates the potential of grassed tramway tracks (or green tracks) in contributing to sustainable urban mobility and aligning with the United Nations Sustainable Development Goals (SDGs). The study highlights the transformative potential of green tracks by analyzing ecological impact, carbon sequestration, and a comparative evaluation of ecological footprints. The findings emphasize their role in mitigating climate change, enhancing urban biodiversity, and promoting resilient infrastructure, positioning them as a critical solution for achieving sustainable urban development.
