Every year, the essay competition focuses on a different global sustainability challenge. This year’s theme is “Navigating El Niño.” Participating students are invited to create a piece of artwork, music, video, poem, essay, letter, or story. The Grand Prize trophy winner will receive a free international trip to a TSL Summit, including £1000 spending money. Schools have to register a Teacher Champion to participate in the competition. The deadline for essay entries is 01 March 2027. Details
