本研究は、EUのETS2（建物・道路交通への排出権取引拡大）による炭素価格負担の世帯脆弱性を、構造的炭素曝露と社会経済的感受性の二つのチャネルに分解して分析。2010～2024年のEU27か国データを用いたクラスター分析・収束テスト・固定効果モデルの結果、両チャネルは地理的に分化し、高い曝露と高い感受性が同時に生じる国グループは存在しない。また、エネルギー生産性向上や再生可能エネルギー拡大が構造的曝露を減らす一方で社会経済的感受性を高める「移行負担メカニズム」が示唆された。政策含意として、両チャネルに対応した差別化補償メカニズムと構造的政策介入の必要性を提言。
English
This study decomposes household vulnerability to ETS2 carbon pricing into structural carbon exposure and socio-economic sensitivity using a dual-channel framework. Analyzing 27 EU member states (2010-2024) with cluster analysis, convergence tests, and fixed-effects models, it finds that the two channels are geographically distinct, with no country group exhibiting both high exposure and high sensitivity. Energy productivity and renewable expansion reduce exposure but increase sensitivity, indicating a transitional burden mechanism. The results call for differentiated compensation and structural policies to ensure an equitable energy transition under ETS2.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも炭素価格制度（GXリーグ、化石燃料賦課金等）の本格化が進む中、本論文は炭素価格が家計に与える負担の構造的二重性を明らかにし、補償メカニズム設計に重要な示唆を与える。特に、エネルギー転換に伴う「移行負担」が日本の政策立案においても考慮すべき点を示唆している。
In the global GX context
As the EU pioneers ETS2 for buildings and road transport, this paper offers a rigorous framework for assessing the distributional impacts of carbon pricing. The dual-channel approach distinguishing exposure and sensitivity is highly relevant for global policymakers designing socially just carbon pricing mechanisms, including in the context of ISSB and transition finance debates.
👥 読者別の含意
🔬研究者:The dual-channel vulnerability framework and the use of convergence tests offer a methodological contribution for studying carbon pricing impacts across heterogeneous regions.
🏛政策担当者:The finding that compensation mechanisms need to target both structural exposure and socio-economic sensitivity is crucial for designing equitable carbon pricing policies.
📄 Abstract（原文）
The extension of the European Union Emissions Trading System to buildings and road transport (ETS2) raises important questions about the distribution of carbon pricing burdens across Member States. While existing research has primarily focused on income differences or household typologies, the structural heterogeneity of vulnerability across EU countries remains insufficiently explored. This study develops a dual-channel framework of household vulnerability to ETS2, distinguishing between structural carbon exposure and socio-economic sensitivity. Using a balanced panel of 27 EU Member States over 2010–2024, we construct composite indices based on Eurostat data and combine cluster analysis, sigma-convergence tests, and two-way fixed-effects models with Driscoll–Kraay standard errors. The results suggest that the two vulnerability channels are empirically distinct and geographically differentiated across Member States, with no country group simultaneously characterized by high exposure and high sensitivity. Energy productivity and renewable energy expansion are associated with lower structural exposure but higher socio-economic sensitivity, consistent with a transitional burden mechanism. Over time, composite vulnerability exhibits statistically significant divergence, despite partial and uneven convergence across the underlying vulnerability dimensions. These findings highlight the need for differentiated compensation mechanisms and structural policy interventions that address both structural exposure and socio-economic sensitivity, supporting a socially equitable and sustainable energy transition under ETS2.
