Home » Tools CatalogueFair Supply’s extinction risk footprint Fair Supply Fair Supply’s platform quantifies the species extinction risk embodied in supply chains. Using basic business data, you can map your entire supply chain portfolio and gain an understanding of the associated species extinction risk. The species extinction risk footprint calculated is presented by entity, by location, and by sector. Our methodology uses input-output analysis to map more than 40 billion global supply chains, and connects the sectors and locations at each node of those supply chains to the activities that threaten species, as recorded in the IUCN’s Red List of Threatened Species. The resultant species extinction risk is quantified using the nSTAR metric, a unit-less measure of extinction risk first proposed in the following scientific paper: https://doi.org/10.1038/s41598-022-09827-0 Visit Tool Case study: Locating and assessing operational and supply chain interfaces with biodiversity This case study has been prepared by the tool provider as an illustrative example of the tools application to the TNFD recommendations and guidance. The TNFD had not endorsed this case study.
