Climate change is challenging health systems to simultaneously strengthen resilience, reduce environmental impacts, and deliver high-quality, equitable care. This panel showcases innovative approaches to health system transformation.
Presentations will explore embedding climate resilience and sustainability into hospital operations, regional collaboration to prepare health systems for climate-related hazards, decarbonizing respiratory care through clinical, digital, and policy innovations, and measuring the financial and environmental benefits of alternative models of care. Together, these examples demonstrate how healthcare organizations can integrate sustainability, resilience, quality improvement, and equity to create health systems that are better prepared for future climate challenges while improving care today.
