First, this paper shows how the circular economy can help achieve climate and other ESG goals while creating opportunities for new forms of better economic growth, effectively moving beyond the initial progress and focus that ESG investment has achieved over recent years. Second, it highlights how investors, banks, and insurers are already capturing these opportunities, showing that the market for financing the circular economy is rapidly taking off across asset classes and sectors. Third, it provides a direction of travel for finance to fully capitalise on the opportunity by helping to rapidly scale the circular conomy. This paper is intended as an initial exploration rather than a detailed analysis of any individual aspect of finance. Its purpose is to stimulate discussion about how the financial services sector can help scale the circular economy to drive new and better growth that is more distributed, diverse and inclusive, and help build an economy that is restorative and regenerative by design.
