AntiLoop is an innovative digital platform crafted specifically for children and youth, aimed at enhancing their understanding of climate impact through real-time data gathered from IoT sensors installed in and around schools. By monitoring variables like CO2 levels, air quality, food waste, and solar energy production, the tool enables students and teachers to observe the direct effects of daily activities on their environment. Designed to seamlessly integrate with school curricula without burdening educators, AntiLoop fosters engaging, data-driven discussions that promote sustainable habits from an early age. Its user-friendly, scalable interface allows schools to customize dashboards swiftly, encouraging quiet changes that contribute to a livable climate. Currently deployed in ten Swedish schools, AntiLoop aspires to become a worldwide resource for climate education among young learners.
