The CTBUH conference, “Vertical Urbanism: Density, Carbon and People,” held 10–12 December 2025 in Mumbai, brought together over 600 industry leaders to explore sustainable, high-density urban development. In partnership with the CVU India Chapter, the event focused on balancing density, carbon reduction, and human-centered design through discussions, case studies, and collaborative sessions. Key topics included net-zero skyscrapers, transit-oriented development, technological innovation, and policy frameworks. The resulting publication captures these insights as a lasting resource for shaping more sustainable and livable cities.
