本論文は、製品炭素フットプリント（PCF）を信頼性高く共有するためのTrustworthy Supply chain eXchange（TSX）を提案する。AnonCredsの選択的開示機能を用いた検証可能な資格情報とブロックチェーン基盤により、機密性を保ちつつ動的PCFを共有可能とし、サプライチェーン全体でのScope 3排出量の正確な把握に貢献する。
English
This paper presents TSX, a trustworthy supply chain exchange for product carbon footprint (PCF) sharing. Using AnonCreds verifiable credentials with selective disclosure and blockchain, it enables dynamic, authentic, and integrity-protected PCF sharing across organizations, addressing confidentiality constraints that previously forced static estimates. The approach is adaptable to any PCF standard.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業にとっては、EUなどのサプライチェーン開示要求に対応するため、信頼性の高いPCF共有が重要。SSBJ開示やScope 3算定の負担軽減に寄与し、サプライヤーとのデータ連携基盤として有用。
In the global GX context
As global disclosure frameworks (TCFD, ISSB, CSRD) demand more granular carbon data, this paper offers a technical architecture to make PCF sharing reliable and standardized, reducing greenwashing risks and enabling dynamic emissions tracking across borders.
👥 読者別の含意
🔬研究者:For GX researchers, this provides a concrete blockchain/verifiable credentials design for interoperable PCF disclosure.
🏢実務担当者:Corporate sustainability teams can leverage this approach to meet customer PCF requests and strengthen Scope 3 data quality.
🏛政策担当者:Policymakers may find this relevant for shaping standards around digital product passports and verified carbon data exchange.
📄 Abstract（原文）
Product Carbon Footprint (PCF) is a systematic measure of the greenhouse gases (GHG) emissions in creating a product. There are several standards for PCF accounting, but sharing the PCF in a verifiable manner is not standardized. The current processes typically rely on sharing digital documents that assert what is typically an estimated and static PCF. In this paper we present our Trustworthy Supply chain eXchange (TSX) approach and compare different technologies that can be used to implement it. Our approach helps the manufacturers to compute the dynamic PCF of products and enables sharing the PCF with other stakeholders by technically solving the confidentiality concerns which led to estimated and static PCFs in the past. We achieve this with the use of the selective disclosure feature in the verifiable credential (VC) technology provided by the AnonCreds VCs. Moreover, the PCF sharing is integrity protected and establishes the authenticity of the PCF data. We use blockchain as an infrastructure that aids in sharing verifiable PCF across organizations and countries. Lastly, our approach has the flexibility to be adopted for any standard of PCF accounting.
