Catena-X Product Carbon Footprint Rulebook
This document aims to reduce the room for interpretation, with a focsss on the exchange of production carbon footprints from tier to tier with increased consistency for PCF accounting. This increased consistency will ensure comparability for the PCFs of parts and components and allow for part and supplier selection. Consequently, the Catena-X Rulebook focusses on the production stage of vehicles.
Allocation
The current version of the guidance has an additional market price hierarchy for economical allocation
Biogenic emissions and removals:
The two guidance are not fully aligned. PACT adapted with the upcoming GHG protocol Land Sectoral and removal Guidance while Catena-X will evaluate its relevance before deciding on adapting the Catena-X guidance
Recycling and energy recovery
The current version of the guidance use the cut-off approach for waste treatment, however the "polluter pays principle" is applied for energy recovery/waste to energy
To align with PACT Methodology: Use the recycled content method as indicated in Chapter 3.3.2.3 of the PACT Methodology
Validity period
The current version of the guidance mandates a yearly checks and if the reported emission increases > 10% based on the screening study compared to the previous reporting period an update of data is mandatory
To align with PACT Methodology: Follow the 3-year cycle or earlier if > 10% variance criteria as indicated in Chapter 3.2.3 of the PACT Methodology
Data quality metrics
The current version assess the data quality of activity data, emission factors, and/or direct emissions while the PACT Methodology only assess emission factors, and/or direct emissions
To align with PACT Methodology: Use the data quality metrics as indicated in Chapter 4.2 of the PACT Methodology
Verification
The current version of the guidance does not include specific requirements about the level and basis for verification. However, a separate document has been developed.
To align with PACT Methodology: Follow the requirements specified in Chapter 5 of the PACT Methodology
