The article How to globalize the circular economy, published by international scientific journal Nature on 9 January 2019, calls for a global initiative to advance the circular economy. It should be led by the United Nations and involve G20 countries, the World Economic Forum, industry and citizen-oriented organizations. It should gather data, draw lessons, trigger learning and share experiences on how businesses and people use and recycle resources. Policies, missions and incentives should be developed to spread circular-economy practices worldwide.
