The Oxford Saïd Global Climate Tech Challenge (formerly the Global Climate Change Challenge) is an annual international competition run by Saïd Business School at the University of Oxford. It invites teams of 3-5 high school students aged 15-18 from around the world to propose innovative, technology-driven solutions to pressing climate challenges including air pollution, extreme weather events, food security, water scarcity, and biodiversity loss. The competition is free to enter and open to students globally. Finalist teams are invited to present their ideas in person at Saïd Business School in Oxford, with all travel and accommodation expenses covered. The 2026 winning student team receives a full scholarship to a Youth Education summer school in Oxford in 2027. The challenge attracted over 1,600 entries from 75 countries in 2025 and continues to grow as a platform for youth climate innovation.
Deadline check (2026-11-03): The official 2026 challenge page retains the December 1, 2025–August 17, 2026 entry window, closing at 11:59 p.m. GMT. It scheduled finalist announcements for September and Oxford finals for October 2026; those published dates are historical, not confirmation that each event occurred. The winner’s summer-school prize is in 2027, which does not establish a 2027 competition application cycle. No next-cycle deadline was found on the checked page.
