本研究は、韓国の地域別炭素フローをスコープ1～3で統合的に評価し、産業地域と首都圏で移行リスクの非対称性を明らかにした。炭素暴露と責任ミスマッチの指標を用い、4つの移行リスク類型を特定。開示制度の拡大が地域の構造的位置に応じて異なる脆弱性をもたらすことを示した。
English
This study provides the first multi-scope regional assessment of carbon flows in South Korea, integrating Scope 1-3 emissions. It reveals stark asymmetries: industrial provinces face high direct exposure, while metropolitan regions have high Scope 3 dependence. Four transition risk archetypes are identified, showing that regional vulnerability stems from structural positions in national supply chains under expanding climate disclosure regimes.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
韓国を対象とするが、日本でも地域間の排出構造格差はGX政策の重要な論点である。本稿の枠組みは、日本の都道府県レベルでのスコープ別移行リスク評価にも応用可能であり、SSBJ開示や地域脱炭素政策への示唆を含む。
In the global GX context
This paper contributes to the global literature on transition risk assessment by providing a regionally explicit, multi-scope framework. It demonstrates how supply-chain-based disclosure (Scope 3) creates uneven vulnerabilities across regions, relevant for TCFD, ISSB, and national climate policy design.

📄 Abstract（原文）
Global climate regulations increasingly extend carbon responsibility beyond direct emitters to the supply chains that sustain regional economies. Yet little is known about how these disclosure regimes redistribute transition risks across regions within a country. This study provides the first nationwide, multi-scope assessment of South Korea’s regional carbon flows by integrating production-based (Scope 1), energy-related (Scope 2) and supply chain embedded (Scope 3) emissions into a regionally extended input-output framework. We develop two indicators, carbon exposure and responsibility mismatch, to capture both the absolute scale of regional emissions and the structural gap between where emissions occur and where they are economically induced. The results reveal stark asymmetries. Industrial provinces such as Chungcheongnam-do and Jeollanam-do exhibit high exposure driven by energy and material intensive production, indicating strong vulnerability to carbon pricing and industrial decarbonization obligations. In contrast, metropolitan regions such as Seoul and Gyeonggi-do show low direct emissions but extremely high Scope 3 dependence, exposing them to disclosure driven risks as embodied emissions become increasingly visible. Cluster analysis identifies four transition risk archetypes, demonstrating that regional vulnerabilities stem not from emission magnitude alone but from structural positioning within national supply chains. These findings contribute to the literature by providing a regionally explicit, multi-scope framework for assessing transition risks, highlighting how structural positions within national supply chains shape regional vulnerability under expanding climate disclosure regimes.
