CX-0134 Product Carbon Footprint Calculation Integration v1.0.0
ABSTRACT
Catena-X claims to be a flexible and open ecosystem of business applications and infrastructure components for data exchange along the automotive supply chain., e.g. in context of PCF (Product Carboon Footprint) values. For interoperability in the Catena-X network, applications that handle PCF data need to follow the according standards as published by the Catena-X association. As per today, there are several certified COTS (Commercial-Off-The-Shelf) solutions available for PCF data exchange. For PCF calculation solutions, the following specification of a standardized integration can be utilized by PCF calculation solution providers for connecting their applications with PCF data exchange solutions. The specification of this integration represents the scope of the standardard.
FOR WHOM IS THE STANDARD DESIGNED
The CX-0134 specifies the integration of PCF (Product Carbon Footprint) calculation solutions in a way that application providers can integrate their solutions in Catena-X. For interoperability, business applications with functionalities for calculation of PCF data need to implement the specified standard.
A list of roles for whom this standard applies is described in Audience & Scope.
1 INTRODUCTION
1.1 AUDIENCE & SCOPE
This section is non-normative
This standard applies to the roles:
- Data Provider / Consumer
- Business Application Provider
1.2 CONTEXT AND ARCHITECTURE FIT
This section is non-normative
This documents shows
- how PCF values are calculated in a Catena-X compliant manner
- how PCF data in Catena-X can be transferred between PCF Calculation and PCF Exchange tools
- which standards needs to be fulfilled in context of PCF calculation integration in order to be interoperable in the Catena-X network
The following scenario describes, how
- a supplier
- calculates the PCF for his component
- transfers the calculation result to the PCF exchange solution
- provides the PCF to his customer
- a customer
- consumes the PCF from his supplier
- transfers the calculation result from his supplier to the PCF calculation tool
- uses the suppliers calculation result for his PCF calculation
1.3 CONFORMANCE AND PROOF OF CONFORMITY
This section is non-normative
As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.
The key words MAY, MUST, MUST NOT, OPTIONAL, RECOMMENDED, REQUIRED, SHOULD and SHOULD NOT in this document document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
All participants and their solutions will need to prove, that they are conform with the Catena-X standards. To validate that the standards are applied correctly, Catena-X employs Conformity Assessment Bodies (CABs).
1.4 EXAMPLES
Section 2.2 PCF CALCULATION DATA FORMAT describes the relevant data structure in context of integrating PCF calculation tools in Catena-X.
An exemplary data set based on this specification can be found here: CSV Example
1.5 TERMINOLOGY
This section is non-normative
The following terms are especially relevant for the understanding of the standard:
Product Carbon Footprint (PCF)
Total GHG (Greenhouse Gas) emissions generated during the life cycle of a product, measured in CO2e. Within the boundary of the Catena-X PCF Rulebook (see CX - 0029 Product Carbon Footprint Rulebook v2.0.0), emissions related to the product use and end-of-life stages are excluded from the PCF.
2 MAIN CONTENT
This section is normative
To prove conformity with the PCF calculation integration standard, the following criteria MUST be applied:
2.1 PCF CALCULATION METHODOLOGY
The methodology used for calculating a PCF MUST be conformant with CX - 0029 Product Carbon Footprint Rulebook v2.0.0.
2.2 PCF CALCULATION DATA FORMAT
For the integration of PCF calculation solutions, the data format is derived from the standard PCF data model as described in CX - 0026 Product Carbon Footprint Data Model v2.0.0, though in integration context some individual properties are not mandatory but can be specified optionally.
The data format for the integration of PCF calculation solutions in Catena-X MUST follow the following specification:
