The energy-and-material valuation (VEM) of the French forest-wood sector, visualised as a Sankey diagram: material is followed from the forest resource through to its end uses, energy and materials alike, in a single flow scheme.
The stages of the sector, from the forest resource to end uses. Arrow thickness is proportional to quantities, so the relative weight of each segment can be read at a glance, along with the way material splits between energy and material valuation.
This work is exploratory: the figures illustrate the structure of the flows and are not a validated sector result.
