More and more data on sustainability is created over the whole supply chain, first and foremost greenhouse gas emission. Verification is required to ensure the reliability of this data for stakeholders. But as the amount of data rises and supply chains are getting more complex, product carbon footprint (PCF) accounting and verification as practiced today face many scalability hurdles. Time consuming on-site audits, non-uniform documentation, secrets about the supply chain, manual information gathering, validation of gathered data and information sharing via mail are common problems, which result in a high price for the customer. TÜV SÜD and an industrial partner want to give insights and results from pilot projects on how these problems can be resolved and what the PCF process of the future may look like.
