PCF Use Case (Catena‐X)
This use case description is based on the Catena-X PCF use case. The main differences are:
- Using of standard modeling notations for diagrams
- Using a improved Catena-X KIT structure that is currently piloted in the Catena-X use case Due Diligence Check (SME).
Sustainability has become increasingly important in the automotive industry in recent years. In particular, the topic of CO2 emissions is the focus of interest, and the product-specific CO2 footprint (PCF: product carbon footprint) has developed into a key indicator for sustainable product design and supply chains. Accordingly, there is a need to determine this data as precisely as possible across the automotive supply chain and to exchange it among partners in the network. This requires appropriate standards for calculation and exchange of data.
In this context, Catena-X offers a decentralized ecosystem supported by standards and principles like data sovereignty, which can effectively implement such a PCF data exchange. The PCF KIT will be the key enabler for various stakeholders to calculate and exchange PCF data in a standardized format. The objective of the PCF KIT is therefore to:
Provide a comprehensive overview about the methods and tools for a PCF data exchange in the Catena-X dataspace. Offer various standards and guidelines for industry stakeholders. Provide a detailed description of the essential components required.
The PCF Exchange KIT can be used to exchange PCF data within the Catena-X ecosystem in a decentralized and interoperable manner, while maintaining a high level of data sovereignty. To achieve this, the PCF Exchange KIT leverages other KITs (particularly the platform-related ones), standardized data models, and an Identity and Access Management (IAM) system based on OAuth and Self-Sovereign Identity (SSI) technology.
In order to ensure interoperability, as described in the section on Semantic Models, a standardized data model is essential. However, it's not only the data model but also the standardized interfaces (both the PCF Exchange API and the standardized API provided by the Connector KIT) that contribute to interoperability.
To enable data sovereignty, Catena-X relies on Self-Sovereign-Identity (SSI). This allows data providers to precisely specify the conditions that must be met before requested data is transmitted. In the context of the PCF KIT, the "PCF Credential" and "Membership Credential" are mandatory. The PCF Credential references the PCF Framework Agreement signed by a data consumer. The Membership Credential additionally ensures that the requester is an active member of Catena-X.
The diagram shown here illustrates the interaction between the PCF KIT and the other Catena-X components.
This section describes why an organization would invest in creating a solution for exchanging PCF data in their supply chain.
This section the updated design of the business that is required to implement the PCF use case.
