Catena-X: Overview and Activation

This article provides an overview of the Catena-X standard in Climate Hub: what it is used for, how it is activated for a PCF report, what changes upon activation, and which areas are affected. For field-level details, please see the linked articles on Base Data and Allocation.

What is the Catena-X standard?

Catena-X is an industry-wide standard for exchanging Product Carbon Footprints (PCF) in the automotive and supplier industry. It defines binding methodological requirements so that PCF values can be exchanged between companies in a comparable and machine-readable format.

In Climate Hub, you can optionally activate the Catena-X standard for a PCF report. This fixes certain inputs and restricts the selection of individual methods.

How is Catena-X activated?

The applicable standards are determined when creating a report. In the "Create Report" dialog, select the desired standards under "Standards be applied". ISO 14067 is preset and always active; Catena-X or PACT can be added in addition.

Important: Only one of the two additional standards can be selected at a time — Catena-X and PACT cannot be selected simultaneously.

The standard selection cannot be changed after the report has been created — no additional standards can be added afterward. Therefore, be sure to determine the required standards already at the time of report creation.


What does activating the Catena-X standard do?

If Catena-X is active for the report, it is displayed in the report header next to ISO 14067. It affects the following areas:

  • Base Data: The system boundary, reference unit, and cut-off rule are fixed; additionally, the "Additional Information in compliance with Catena-X" section appears, containing the mandatory field Net Weight per Declared Unit. For a field overview, see the Base Data article.
  • Allocation: A reduced selection of allocation methods is available compared to ISO 14067. For details, see the article Allocation.
  • Emission Factors: Catena-X only allows ecoinvent emission factors from versions 3.11 and 3.12. The following features of the ISO standard are not available in the PACT standard: search for spend-based emission factors, selection of a predefined standard activity via a dropdown menu, search for activity-based emission factors from databases other than ecoinvent.
In the Data tab, the input is the same for all standards. Standard-related differences are only shown here per emission factor: it indicates whether the respective emission factor is mandatory or optional for the selected standard.
