About the 2021 Sustainability Challenge
Theme: Protecting biodiversity
The TSL Sustainability Challenge is a video contest for learners worldwide, organised in parallel with our annual International Schools Essay Competition & Debate.
The Sustainability Challenge provides a platform for voices to be heard and recognises and rewards the sustainability ideas, actions and leadership of learners of all ages.
The overall winner will be awarded the 2021 Challenge Trophy and a cash prize of £500 or equivalent. The winning entry for each age category will receive a special e-medal and gift.
The winners will be announced on 1 May 2021, as part of the lead-up to the next Conference of Parties (COP 15) of the UN Convention on Biological Diversity (CBD). The winning videos will be sent to UN Secretary General António Guterres and other leaders in the international community.
