Momentum builds at Planetary Health Cities Symposium to shape healthier cities for people and planet


The 2025 Planetary Health Cities Symposium, co-hosted by the Johns Hopkins Institute for Planetary Health and the Carey Business School, brought together global leaders across science, business, policy, and urban planning to reimagine urban life through a Planetary Health lens. With urban populations projected to grow by 1.1 billion in the next decade, sessions explored how cities can safeguard both human health and the planet’s life-support systems. Speakers stressed the need to move beyond a narrow focus on decarbonization to also address toxic building materials, biodiversity loss, and social inequities, while highlighting solutions such as green building standards, community health data tools, and integrated resilience. From addressing “Cancer Alley” in Louisiana to embedding heat resilience in Miami-Dade and strengthening elder care in East Asia, the symposium emphasized the importance of transdisciplinary collaboration and systemic change to foster healthier, more regenerative cities. Looking ahead, the initiative aims to co-develop shared design principles and support the growth of Planetary Health Cities worldwide for the health of both people and planet.

Read a detailed report on these developments and their implications for our global movement.

Together, we plan to reshape how the industry thinks about sustainability and the built environment. We want to expand the current narrow focus on just decarbonization to encompass broader environmental and human health concerns.
