Houdini publishes ambitious planetary-boundaries science but does not quantify its actual emissions. Fabric use grew 70% in a decade while virgin synthetics stayed at 48%. Missing: GHG inventory, SBTi target, renewable energy disclosure, water monitoring, biodiversity metrics. Circular product claims are self-reported and unverified.
