本研究は、従来の画一的な枠組みを超え、循環炭素経済(CCE)下のサプライチェーン全体に適用可能な統合マテリアルフロー原価計算(MFCA)モデルを開発した。物理量と炭素密度を統一度量に統合し、農薬・生化学セクターの5つの数量センターを含むサプライチェーンに適用した結果、総廃棄物5,478トン(投入の19.3%)、炭素廃棄コスト187,260米ドル、平均炭素循環閉鎖指数0.79が示された。MFCAとチェーン単位の炭素開示要件の統合という会計文献の空白を埋め、強制炭素価格制度下の企業に実用的枠組みを提供する。
English
This study develops an integrated material flow cost accounting (MFCA) model extending beyond one-size-fits-all frameworks to full supply chains under the circular carbon economy. Applying it to an agrobiochemical supply chain with five quantity centers, it found 5,478 tonnes of material waste (19.3% of inputs), US$187,260 in carbon waste cost, and an average carbon cycle closure index of 0.79. The work bridges MFCA with chain-level carbon disclosure requirements, offering an actionable accounting tool for firms under mandatory carbon pricing.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ基準や有報でのScope3開示義務化が進む中、MFCAはマテリアルフローと炭素コストを統合的に可視化する手法として、製造業のサプライチェーン排出管理や統合報告書での説明力向上に寄与しうる。炭素価格制度下でのコスト管理と開示を両立させる実務的示唆がある。
In the global GX context
Globally, this contributes to the growing need for accounting tools that integrate physical material flows with carbon metrics, aligning with ISSB/CSRD requirements for supply-chain emissions and circular economy disclosure. It offers a methodology for firms facing carbon pricing to quantify both waste costs and decarbonization incentives across the value chain.
👥 読者別の含意
🔬研究者:MFCAと炭素会計の統合という会計学の空白を埋める理論的・実証的貢献として注目。
🏢実務担当者:サプライチェーン全体の炭素コストと廃棄物を可視化し、炭素価格下でのコスト削減と開示対応に活用可能。
🏛政策担当者:炭素価格制度下での企業会計と開示の整合性を図る枠組みとして、政策設計の参考になる。
📄 Abstract(原文)
<title>Abstract</title> <p>This study aims to develop an integrated material flow cost accounting (MFCA) model that goes beyond the traditional one-size-fits-all framework and extends to complete supply chains under the requirements of a closed carbon economy (CCE). The proposed model is based on three core pillars: first, integrating the dimensions of physical mass and carbon density into a unified unit of measurement; The applied study is conducted on an integrated supply chain in the agrobiochemical sector that includes five Quantities (QC) centers, through three methodological stages: building the theoretical model, applying it to case data, and then analyzing the scenarios. The results showed that the total material waste was 5,478 tonnes (19.3% of the inputs), and the cost of carbon waste was US$187,260, while the average carbon cycle closure index was 0.79, indicating measurable improvement potential. The study makes a theoretical and practical contribution, filling a gap in the accounting literature related to the integration of MFCA with chain-level carbon disclosure requirements, and provides a framework that is actually applicable in enterprises operating under mandatory carbon pricing systems. By bridging material flow cost accounting with circular carbon economy metrics across supply chain stages, this study provides an actionable accounting tool to advance Sustainable Development Goals (SDGs), particularly SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action), through quantifiable waste reduction and decarbonization incentives.</p>
