The Alliance for Sustainable Schools (TASS) is a non-profit network of schools working together to help accelerate the transition to a sustainable future. Our members share a commitment to the principles of the Sustainable Schools Charter. As a community of practise, The Alliance connects sustainability practitioners in schools around the world, sharing their learning and amplifying their impact. As an agent of change, we harness the collective influence of our members, engage with their students, and partner with innovative organisations in their local communities to catalyse systems change in five focus areas – school food, school buses, school uniforms, school buildings and education for sustainability.
