本研究は、上流・下流の排出を統合したサプライチェーン全体の排出量算定フレームワークを開発。GLORIAデータを用い、中国、米国、インド、ロシア、日本が主要排出国であることを特定。先進国では下流排出が増加し、新興国では上流排出が増加（特に電気・機械部門）。低炭素サプライチェーンに向け、取引先産業の排出開示義務化を提言。

English

This study develops a supply chain-based emissions accounting framework integrating upstream and downstream emissions. Using GLORIA data, it identifies China, US, India, Russia, and Japan as top emitters. Developed countries show rising downstream emissions, while emerging economies increase upstream emissions, especially in electrical and machinery sectors. It advocates mandatory disclosure of trading partners' emissions to promote low-carbon supply chains.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本は主要排出国として特定され、サプライチェーン排出の把握がSSBJ開示やScope3対応に直結する。取引先排出の開示義務化提言は、日本のサプライヤーへの影響が大きく、政策・実務の両面で示唆に富む。

In the global GX context

This paper contributes to global Scope 3 accounting by proposing a comprehensive supply chain framework. It highlights the shift in emissions across developed and emerging economies, informing ISSB-aligned disclosure policies and supply chain decarbonization strategies.

👥 読者別の含意

🔬研究者:Provides a novel methodology for full supply chain emissions accounting and empirical insights across countries and sectors.

🏢実務担当者:Useful for companies to understand supply chain emissions hotspots and prepare for mandatory disclosure requirements.

🏛政策担当者:Supports policy design for mandatory emissions disclosure and targeted interventions in high-emission supply chains.

📄 Abstract（原文）

Existing Scope 3 emissions accounting methods typically consider emissions from either the upstream or downstream sectors. This study develops a supply chain-based emissions accounting framework to quantify emissions across the entire supply chain, that is, upstream and downstream emissions. Using the GLORIA multi-regional database, the study identifies major emitters-China, the U.S., India, Russia, and Japan-as having the highest supply chain emissions. A shift toward higher downstream emissions is noted in developed countries, while emerging economies have increased upstream emissions, particularly in electrical and machinery sectors between 2000 and 2019. Emissions shares vary across developed and BRICS countries, highlighting the need for targeted policies. To promote low-carbon supply chains, the study advocates for mandatory disclosure of emissions from trading partners' industries, encouraging environmentally responsible sourcing.
