This session will explore how San Diego County is advancing a just and equitable transition to a circular economy through a regionwide assessment and roadmap that will deliver actionable solutions prioritizing regeneration, reuse, repair, recycling, and remanufacturing. It will highlight the cross-cutting opportunities for circularity to foster entrepreneurship and strengthen regional markets while addressing zero waste goals, promoting environmental justice, and accelerating climate action. Participants will gain insights into the systems analysis, engagement approach, and policy pathways developed through this data-driven, multi‑stakeholder initiative, with a focus on the unique capacity of regional governments to drive the transition toward a regenerative, low‑carbon economy.
