​At the Smart City World Expo 2024, Rosa Arias, founder and CEO of Science for Change, sat down with us and discussed the OdourCollect app—a citizen science initiative addressing odour pollution. Developed from her experience in environmental consulting, OdourCollect empowers individuals to report odour nuisances, creating real-time maps that inform public policies and promote community engagement.This approach not only raises awareness of often-overlooked environmental issues but also fosters inclusive participation in urban decision-making processes.​
