Aviation supply chains can contribute to biodiversity pressure through materials used in uniforms, catering, textiles, packaging, chemicals and fuel supply. 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 TNFD, ISSB and CSRD aligned reporting and helps aviation teams consider nature related impacts across procurement.
