This workshop brings together scholars and practitioners to discuss the role of green schoolyards as a strategy for environmental justice, health and city climate planning. In many cities, children in low-income and marginalized communities are disproportionately exposed to extreme heat, air pollution, flooding, and limited access to safe green space. Transforming schoolyards into green, multifunctional environments offers an innovative place-based intervention that advances climate adaptation while addressing long-standing health and environmental inequities. Through a comparative analysis of three global cities, scholars, policy makers and practitioners will share experiences on how urban climate and sustainability policy, planning, and governance decisions can either reinforce or reduce environmental injustice—and how schoolyard greening can be used to advance more equitable urban futures. Specifically, the workshop aims to collectively examine how green schoolyards can be meaningfully integrated into city climate and public health plans to prioritize communities most impacted by climate change and structural inequities.
