Measuring the Circular City
Solid circular planning and decision making requires an understanding of the material and energy flows entering, being consumed, transformed or stocked in and leaving cities, or, in other words, the urban metabolism. This includes measuring material, waste, water and energy flows and stocks in cities, and getting an idea about the (utility) infrastructures, actors and companies that facilitate those. Gathering and visualising this data, helps to identify where and how to intervene and which loops to close. It provides cities with insights into their economic activities and allows connecting the dots between current initiatives and their potential to make their city more circular.
Cities need to understand how their activities impact the state of the circular economy in their region. To achieve circular goals, these need to be defined and progress needs to be measured. Defining operable circular city indicators helps to understand which parameters need to be measured and where citizens and cities can have most impact.
