Achieving a Sustainable Economy with Digital Product Passports
Carbon Disclosure Project ( CDP ) scores . In this way , complex supply chains can be modeled and conclusions can be derived along the entire supply chain and product structures . For the realization of this use case the concepts product , product passport , property and semantic reference of the SFW Capability Model have been introduced ( Figure 4-2 ). The derivation of supply chains is possible in the following way :
• Referencing along the product hierarchy ( reflexive relation containsSubProduct ) allows one to derive the sub-products . Manufacturer information can be derived from a product or the DPP . The individual products in turn have a DPP . Based on this DPP , the dashed relation refers _ to can be used to derive the corresponding product ( Figure
5-5 ).

5-5 : Derivation of supply chains from DPPs .
DPPs are characterized by a unique identifier and various properties . Properties can have references to semantic descriptions . Unique referencing and semantic comparability are advantages of this modeling approach .
As described previously , DPPs will not only have to be managed centrally in the supply chain management application but will also be searched and linked via external referencing to support distributed DPPs . So DPPs can be hosted by the manufacturers themselves or connected via registries .
The Supplier Knowledge Base already supports this distributed approach . However , to fully enable the distributed approach , access control and identity provisioning must be detached from the Supply Chain Management Application and the respective interfaces shall be standards compliant . In future , more and more DPPs will have standardized semantics laid down by company associations in an application domain ( such as the GBA ).
