Last month, CCD signatory Greater Paris Metropolis presented some results from its urban metabolism study. The study among other things showed that the metropolitan "material footprint" amounts to 19 tonnes per inhabitant, with "only" 1.4% of materials extracted locally and 28% from renewable resources. The circularity indicator – the ratio between recycling and local consumption – is 7%

The study also helped show what kind of interventions Greater Paris Metropolis can make to improve the situation. These include reducing waste, developing a sustainable supply, a stronger focus on eco-design, making better use of what already exists and promoting repair, reuse, reconditioning and recycling.

The full results of the study can be found here. To gain a better understanding of urban metabolism, take a look at the work of CCD support partner Metabolism of Cities.
