TSL International Student Competition 2027: "Navigating El Niño", ages 7-18, until 1 March

The Trust for Sustainable Living's international competition is open to students worldwide aged 7-18, in two categories: 7-11 and 12-18 (per the previous season's FAQ). The 2027 theme is "Navigating El Niño". Entries opened on 10 September 2026 and close on 1 March 2027; they are submitted on the Submittable platform through a Teacher Champion, and if a school does not take part, a parent or guardian can act as one. Entries must be in English, and non-native English is welcome. Prizes: the Grand Prize is £1,000 and a trophy and the runner-up receives £500; finalists and winners get certificates, and the top two students from each country and category are invited to the international debates on 1 and 2 July 2027. The FAQ does not mention an entry fee.
