Achieving a Sustainable Economy with Digital Product Passports

The Global Battery Alliance ( GBA ) presented a proof-of-concept battery passport at the World Economic Forum in Davos 2023 ; cf . also [ 10 ]. Catena-X will collaborate with GBA to provide the data backbone for the battery passport in a solution for the automotive industry .
Catena-X has also published seven documents in the category Traceability [ 3 ]. The first three of these documents TRA-001 – TRA-003 describe the identification of serialized ( mass produced ) parts and batches ( a quantity of products produced in the same way ) by considering the part IDs assigned by the manufacturer and customer as well as the serial number of the part instance in the production series . A serialized part may have several local identifiers but has a unique Catena- X identifier in the Catena-X dataspace . The documents TRA-004 – TRA-007 define the protocol to exchange notifications on quality information .
The Eclipse Dataspace Connector ( EDC ) is used as an underlying technology for trustworthy communication with usage policies for the quality data [ 1 ]. Company data is provided to the Catena-X network by transforming it into the Catena-X format and publishing it in the EDC . The company data is represented in Catena-X as a digital twin for each serialized part or batch . The digital twin is realized as an Asset Administration Shell ( AAS ) of Plattform Industrie 4.0 [ 17 ].
The Industrial Digital Twin Association ( IDTA ) is working on AAS sub-model templates to describe PCF and product related environmental data [ 6 ]. A sub-model defines the format and semantics of AAS content .
The Digital Twin Consortium ( DTC ) aims to develop an end-to-end model of carbon emissions in a supply chain together with a vendor-neutral solution for data sharing and reporting emissions and PCF [ 6 ]. DTC intends to include scope 3 emissions covering the logistics , raw materials and PCF of parts used in the supply chain .
