A youth-led initiative in Accra where walkers carry PM2.5 sensors through neighbourhoods such as Nima and Kanda, mapping pockets of dirty air from traffic and open burning. It pairs the data with school outreach and tree planting, aiming for 500 students and at least 153 trees, then a policy dialogue with city leaders.
