Around the world, governments and businesses are talking more and more about the need to move from today's "take, make, waste" economy to a circular one, where products are designed to last, materials stay in use, and waste is dramatically reduced. On paper, the case is compelling: recent assessments show that shifting to a circular economy offers both a major climate opportunity and a significant economic one. A study from the European Commission's Joint Research Centre finds that "reduction, reuse and recovery" measures could cut Europe's heavy industrial emissions by up to 231 million tonnes of CO₂ each year, and global analyses estimate that circular models could generate around $4.5 trillion in value by 2030).
