本Perspectiveは、製品炭素フットプリント（PCF）を購入時に移転可能な要件とする「カーボンフットプリント・クレジット（CFC）」を提案する。CFCはCO2換算1kgにつき1単位で表示される移転可能なアクセス単位で、原材料・中間・最終製品の適格購入には購入量×検証済みPCFの移転が必要となる。発行上限は管轄区域の排出ベースラインと削減経路に連動し得るが、本枠組みは消費者普及や商業的実現可能性、追加削減を立証するものではなく、拡大前に必要な証拠を定義するものだ。
English
This Perspective proposes Carbon Footprint Credit (CFC), a transferable access unit denominated per kg CO2e, requiring eligible purchases of raw materials, intermediates and final products to transfer units equal to quantity times verified PCF. Annual issuance ceilings could be anchored to a jurisdictional emissions baseline and reduction pathway. The framework defines an institutional proposal and the evidence needed before expansion, not consumer adoption or commercial viability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ基準や有報でのScope3開示が進む日本では、開示情報を実際の取引要件に接続する仕組みとして、製品単位の炭素会計・調達実務への示唆が大きい。公共調達や企業間ネットワークでの実証は、日本企業のサプライチェーン脱炭素を促す政策的論点となり得る。
In the global GX context
As ISSB/CSRD push product-level and Scope 3 disclosure, this paper explores how verified PCFs could become a transferable transaction requirement rather than a reporting artifact. It adds to global disclosure-infrastructure scholarship by linking carbon accounting to procurement and exchange design, with pilot settings in public procurement and enterprise networks.
👥 読者別の含意
🔬研究者:製品単位の炭素会計と取引所制度を接続する新たな研究課題を提示する。
🏢実務担当者:調達・サプライチェーンでのPCF検証とCFC移転要件が将来の取引条件になり得る点を注視すべき。
🏛政策担当者:公共調達やパイロット設計を通じ、開示を実効的な炭素価格シグナルに変える制度オプションとして検討に値する。
📄 Abstract（原文）
Product carbon footprints (PCFs) inform consumer choices, procurement and product policy, but their use does not necessarily create a transferable requirement at purchase. This Perspective proposes Carbon Footprint Credit (CFC) as one way to examine such a requirement. CFC is a transferable access unit denominated at one unit per kilogram of CO₂-equivalent. Every eligible purchase, including transactions in raw materials, intermediate products and final products, requires a transfer equal to the purchased quantity multiplied by that product's valid verified PCF. The seller receives the units alongside an independently determined fiat payment and may reuse them within an eligible supplier network. As one pilot-design option, annual ceilings on new CFC issuance may be anchored to a declared jurisdictional emissions baseline and an explicit future emissions-reduction pathway. The baseline year is selected for the relevant planning and assessment context rather than fixed by the CFC concept. Acceptance capacity, enterprise reuse and idle balances guide release within those ceilings; they do not determine the ceilings themselves. We distinguish these issuance and transaction rules from account-stock accounting and environmental claims. The mechanism depends on buyers assigning an opportunity cost to CFC and on firms obtaining benefits that exceed participation costs. Public procurement, enterprise networks and limited resident pilots offer settings for independent evaluation. The framework does not establish consumer adoption, commercial viability or additional emissions reductions. It defines an institutional proposal and the evidence needed to assess it before expansion.
