All resource inflows metrics are estimated using our product lifecycle assessments (LCAs), as these contain verified component-level data, including material composition and measured weight. The LCAs we have available are allocated at the item level across the product portfolio. All LCAs are third-party verified according to ISO 14067. For products currently lacking an LCA, a reference LCA is allocated. Professional judgement is applied in the selection of a reference that will best represent the product or part. An uplift is conducted for items that cannot be represented by an LCA, based on the calculated average per unit volume purchased or produced. For Enterprise, Gaming & Consumer products, one unit packaging per unit product has been assumed.
