Quantifying or qualifying the circular economy?

The transition to the circular economy (CE) in the built environment seems to rest on the development of professional expertise in quantifying the world. CO₂ emissions, Life Cycle Costs, material flows, and the amount of waste recovered and fed back into the economy are all important indicators of the CE and metrics to which the industry is held accountable. These calculations have become a basis for decision-making, as well as a necessity for documenting compliance to legally binding commitments in transnational, national, and sectoral regulation, as well as being evaluated by stakeholders in the market and the wider society.
