The Ellen MacArthur Foundation works across four areas to accelerate the transition to a circular economy: insight and analysis, education and training, business and policy, and communications and publishing. It draws inspiration from past thinkers in related fields like Walter Stahel, McDonough and Braungart, Amory and Hunter Lovins, and Thomas Graedel. The Foundation sees a world of dynamic non-linear systems and believes that economics should reflect science. Its vision includes keeping components and materials in closed loops, renewing rather than depleting resources, and celebrating diversity as a source of innovation and resilience.
