How students can take climate action inside school
Twelve real activities that schools have run with their students.
Climate action for students is usually imagined as marches and posters. The schools in our network run quieter projects that produce measurable results inside the school gate. Twelve that work, drawn from real OMG Lab schools:
1. Grow a weekly tray: a class grows part of its own greens, cutting food miles to zero. 2. Water audit: measure water per tray versus field-grown equivalents and publish the saving. 3. Canteen waste count: weigh plate waste for a week, teach portions, weigh again. 4. Compost corner: growing-media and canteen scraps become soil for the school's outdoor plants.
5. Food-miles map: students trace where one lunch's ingredients travelled from, then re-plan the same meal locally. 6. Label audit: rank the tuck shop's snacks by packaging and hidden sugar, and negotiate one healthier swap. 7. Harvest for the mid-day meal: microgreens from the lab enrich school lunches, the same practice that improves nutrition in OMG partner schools. 8. Seed library: students save, label, and exchange seeds, learning biodiversity by handling it.
9. Home-grow challenge: families adopt a tray for a month; the class tracks total household harvest. 10. Junior trainer programme: older students train younger classes, the model behind OMG's 1,000+ trained teachers. 11. Climate quest league: inter-school rounds on food systems, water, and waste. 12. Harvest showcase: a public presentation of the term's data, crops, and lessons, so the whole community sees what student climate action looks like.
None of these needs a stadium or a sponsor. They need a living lab, a teacher with a plan, and permission to let students run something real. Start with one. The rest tend to follow.
