Product Carbon Footprint (PCF) data exchange

This section outlines the steps required to successfully complete the Product Carbon Footprint (PCF) use case within the Data Space Accelerator study.

Product Carbon Footprint (PCF) data sharing enables transparent and standardized CO₂ reporting across the Catena-X ecosystem, helping companies meet sustainability, compliance, and supply chain requirements through secure exchange via the EDC.

The PCF use case distinguishes between calculating PCF data and exchanging PCF data across company borders. The Data Space Accelerator only requires participants to demonstrate PCF data exchange to receive financial compensation. Participants are welcome to explore PCF calculation further, but it's not required for this program.

Prerequisites

Choose your path

Certified PCF App: Follow your application provider's instructions to complete the PCF exchange with Cofinity-X, then continue from Step 2 (Notify Cofinity-X) below.

Step 1: Create your PCF Exchange Endpoint

Create an Asset with semanticId referencing PCF v9.0.0 and dct:type set to cx-taxo:PcfExchange.

Your usage policy must reference FrameworkAgreement: DataExchangeGovernance:1.0, Membership: active, and UsagePurpose: cx.pcf.base:1.

Create a Contract Definition linking your Asset to this policy.

Step 2: Notify Cofinity-X

Send an email to [email protected] with subject line "DSA PCF request", including:

  • Your EDC URL

  • Your BPNL

  • The Product ID for which you want to share PCF data

Step 3: Prepare your PCF data

Prepare PCF data for the specified Product ID, complying with the Catena-X PCF JSON Schema v9.0.0. Schema-compliant test data is also accepted.

Step 4: Respond to the incoming PCF request

Cofinity-X will send a formal PCF request via contract negotiation. Respond using:

  • EDC URL: https://pcf-dsa-2025-edc.dataspaceos.svc.cofinity-x.com/api/v1/dsp

  • BPNL: BPNLCOFINITYEZFA

  • Asset ID: PCF

What happens next

Cofinity-X will consume and check your data for correctness, completing the validation process for Dataspace readiness. Upon successful validation, you'll receive your Data Readiness Certificate in the DSA portal.
