The challenges of air pollution and climate change are closely linked, with overlapping solutions, and significant public health co-benefits in addressing them. This necessitates a cohesive policy approach toward maximizing co-benefits, and avoiding unintended trade-offs. In this workshop, the California-China Climate Institute will share lessons-learned from its latest study on the policy and technological options available to maximize public health co-benefits, sharing insights from urban cases of Los Angeles, Beijing and Shenzhen. California has integrated public health into its air and climate policies, primarily by incorporating public health indicators in policies, establishing public health monitoring networks, and measuring implementation action. China, meanwhile, has excelled at developing highly sophisticated air quality monitoring tools and a comprehensive climate policy framework. This culminating event aims to present project findings, seek issue-expert commentary, and share local experiences from urban cities in both jurisdictions.
