In a circular economy, growth comes from ‘within’, by increasing the value derived from existing economic structures, products and materials. This major report quantifies the benefits for Europe – in terms of growth, household income, and environmental outcomes – of adopting a circular development path compared with our current linear one. Incorporating in-depth analysis of three of Europe’s largest basic needs, mobility, food and the built environment, the report provides a vision of how the circular economy could look, and highlights wide-ranging implications for government and business leaders.
