Biodiversity risk in construction arises from materials sourcing, land disturbance and upstream production processes. Fair Supply provides supplier specific biodiversity risk scoring using the nSTAR methodology and integrates datasets such as the IUCN (International Union for Conservation of Nature) red List and the Integrated Biodiversity Assessment Tool (IBAT). This supports reporting aligned with TNFD, ISSB and CSRD and helps teams understand supply chain related biodiversity impacts.
