Workshop 07: Bringing supplier-specific product carbon footprints into LCA calculation engines at scale

Main Presenter:    Martina Prox 

Co-Authors:   Florian Ansgar Jäger                                               

Large industry initiatives (e.g. Catena-X, Together for Sustainability, or World Business Council for Sustainable Development) promote aligned calculation methodologies as well as data formats for standardized PCF exchange along the supply chain. The intention is clear: moving from secondary database values to supplier specific PCFs. Providing companies with both the software to request specific PCFs from suppliers and with standardized options for seamless integration into LCA solutions enhances the calculation of internal PCFs with a high primary data share.

During the workshop we would like to explore with the audience which are the success factors and roadblocks of scaling PCF calculation while increasing the use of supplier-specific PCFs.

The workshop will be kicked off with a presentation of a potential approach for automated PCF data transfer in both ways (tier-to-tier) showcasing the integration of a PCF exchange tool, namely SiGREEN by Siemens AG, with a LCA calculation engine, namely iPoint Product Sustainability (PS).

Currently, concepts for transferring PCF values in various ways between PCF Data Exchange Tools and Calculations engines are under development. Workflow proposals will be shared and explained and the audience will be asked to provide their feedback and jointly explore which factors have the biggest influence on successful scaling. We would also like to explore which roles and responsibilities the audience sees around the workflows of PCF calculation and PCF exchange and how this influences scalability.
