In 2018, the Foundation alongside the UN Environment Programme launched the Global Commitment, the biggest global voluntary effort to tackle plastic waste and pollution. In this podcast episode, we hear from Sander Defruyt, Plastics Lead at the Ellen MacArthur Foundation, who reflects on the progress and learnings to date from five years of the Global Commitment, the need for a legally binding global treaty to end plastic pollution, and what makes him feel optimistic about the last five years.
