In a school garden in Reading, children are using micro:bit soil moisture sensors they coded themselves to decide when to water their plants, saving water and learning that technology can solve problems they care about. And across the country, students are building air quality trackers that generate real data for local clean air campaigns, energy monitors that help schools cut waste by setting alarms that tell them when to power down, and wildlife trackers deployed on school grounds to monitor biodiversity.
Digit’s sustainability initiative combines hands-on climate action with inclusive digital learning. Using accessible tools, students build real solutions to local environmental problems. Since launch, we’ve reached 1,050,824 learners and trained 23,020 educators across 59 countries, approximately 500,000 this year alone. All programmes are free and designed with equity at their core, specifically targeting underrepresented groups.
Our train-the-trainer model ensures long-term legacy: 23,000+ trained educators deliver our programmes independently, creating ripple effects well beyond our direct delivery. 1,589 teachers independently delivered Coding for Climate Action to 95,000+ students, demonstrating a model that sustains itself. Student projects have produced tangible environmental outcomes: reducing school energy waste, conserving water, tracking air pollution and supporting biodiversity. After a session, one teacher told us the children “went home absolutely buzzing.”
This initiative shows that sustainability education and digital inclusion are interconnected. When delivered with equity at their core, they transform who gets to participate in both the green and digital economy.
