This is an estimator for readiness, not a life-cycle assessment and not a compliant product footprint. It stops at the factory gate: no distribution, retail, consumer care or end-of-life. Default factors are indicative industry ranges, not authoritative values, and a figure produced here must not be published as a substantiated environmental claim. Use it to find which stage of your supply chain needs primary data - then go and get that data.
