Sharing Data to Achieve Decarbonization of Value Chains

The document addresses the difficulty manufacturers face in establishing accurate emissions baselines due to the high proportion of upstream emissions compared to internal ones. It details a pilot project involving Arçelik, Siemens, and Dow, which developed a decentralized, peer-to-peer data-sharing architecture to exchange PCF data securely. This system utilizes a Trustworthy Supply Chain Exchange (TSX) method, allowing certifiers to verify data authenticity via digitally signed credentials while maintaining supplier confidentiality. The goal is to provide the visibility necessary for companies to set reduction targets and decarbonize their production operations.

• Upstream emissions are significantly larger than internal emissions, with the Carbon Disclosure Project estimating they outweigh internal emissions by a factor of 11.4.
• A pilot collaboration involving Arçelik, Siemens, and Dow simulated a supply network for a washing machine to demonstrate a technical solution for exchanging PCF data across parties.
• The developed technical solution features a distributed peer-to-peer architecture using crypto technology to ensure data is shared only on a request-basis and remains confidential.
• To ensure data sovereignty and compliance with local regulations, the system employs decentralized storage and aggregation of PCF data.
• The project created an open-source ontology and a semantic data model to provide a common interface and standard for interoperability between different databases and systems.
• The Trustworthy Supply Chain Exchange (TSX) method allows a selected certifier to provide digitally signed verifiable credentials that confirm data authenticity without revealing confidential supplier identities.
