After my last post on the Paris Urban Metabolism I continued to research that topic a little more. I came across another example from France. The below Sankey diagram is from an article on territorial metabolism in the rural village of Contres in France. (“H4 développe une démarche de métabolisme territorial à Contres”).

In this study, the consultant company H4 Valorisation analysed the material and energy flows liked to the villages economic and agricultural activities. Different scenarios were evaluated, focusing primarily on (1) reducing imports and rejects (waste and pollutants), (2) increasing usage of local resources, and (3) looking at reuse of material internally (les rebouclages internes).

The Sankey diagram shows both mass and energy in one diagram, so the inputs and outputs of the central node (representing the village of Contres) are not balanced when summed up. Mass flows are in tons (per year?) in blue and red colors. Energy is in Mwh per year and shown in orange color. Greenhouse gas emissions from energy used is also represented in pale yellow expressed in tonnes of CO2-equivalents.
