Governments and businesses are acknowledging that the prevailing ’linear systems of resource use’ expose our societies to serious risks. Resource constraints and increasing volumes of waste and pollution pose a threat to people’s well-being and businesses’ competitiveness and sustainability efforts. The ’circular economy’, conversely, is described as an industrial system that is circular in the cradle-to-cradle-recyclability sense by intention and design. This chapter focuses on some assessed integrated impacts - possible societal benefits - that a transformation from a linear to a circular economy might result in. This has been done by applying “what-if-scenarios” into a for this purpose constructed interactive input–output model with a number of changes linked to a circular economy implemented in the model. The model has then been applied to eight European economies showing close to 70% reductions in CO2-emissions while offering new and additional employment and improving the trade balance of fossil-fuels-importing countries.
