日本語
EU22カ国の農業、製造業、運輸セクターを対象に、DEAを用いて炭素強度、環境非効率性、炭素シャドウプライス（限界削減費用）を推定。製造業と運輸では炭素強度が低下したが、農業は安定。製造業のみ収束傾向を示し、シャドウプライスは農業と運輸で上昇、製造業は低下・乖離。セクター別の政策対応の必要性を強調。
English
This study estimates carbon intensity, environmental inefficiency, and carbon shadow prices (marginal abatement costs) for agriculture, manufacturing, and transport sectors across 22 EU countries from 2008 to 2021 using Data Envelopment Analysis. Manufacturing and transport show declining carbon intensity, while agriculture remains stable. Only manufacturing exhibits convergence in intensity; shadow prices rise for agriculture and transport but decline and diverge for manufacturing, highlighting the need for tailored policies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではセクター別の炭素削減費用の推計や収束分析の事例が少なく、本稿の手法は日本の製造業・農業・運輸の脱炭素政策設計に参考となる。特に、シャドウプライスの乖離は政策の非効率性を示唆し、日本のGX推進におけるセクター間のバランス検討に示唆を与える。
In the global GX context
The paper contributes to global climate policy literature by providing empirical estimates of sectoral carbon shadow prices and convergence patterns across EU countries. The findings on divergent abatement costs underscore the importance of tailored sectoral policies, which is relevant for international frameworks like the Paris Agreement and EU Green Deal. The methodology can be applied to other regions.
👥 読者別の含意
🔬研究者:Provides a robust methodology for estimating sectoral carbon shadow prices and convergence, applicable to other regions or extended with dynamic models.
🏢実務担当者:Offers benchmarks for sectoral carbon intensity and abatement costs that can inform corporate carbon management and investment decisions in EU markets.
🏛政策担当者:Demonstrates the necessity of sector-specific policies; the divergence in shadow prices points to inefficiencies that need corrective measures.
📄 Abstract（原文）
ABSTRACT The European Union has committed to ambitious decarbonisation targets, necessitating a deep understanding of sectoral environmental performance. This study assesses the carbon intensity, environmental inefficiency, and carbon shadow prices of the agriculture, manufacturing, and transport sectors across 22 EU countries from 2008 to 2021. We employ a non‐parametric Data Envelopment Analysis (DEA) with a weak disposability assumption to model carbon dioxide emissions as an undesirable output. This approach allows for the estimation of environmental inefficiency and the shadow prices of carbon, reflecting marginal abatement costs. The findings reveal a decline in carbon intensity for manufacturing and transport, while agriculture's intensity remained stable. Manufacturing is the only sector showing convergence in carbon intensity. Environmental inefficiency was highest in manufacturing, though it improved over the period. Shadow prices for carbon increased in agriculture and transport, indicating rising abatement costs, while manufacturing experienced a sharp decline and subsequent divergence among countries. The divergent performance across sectors highlights the need for tailored policy interventions. While manufacturing has seen progress in decoupling, the increasing disparity in shadow prices suggests inefficiencies in policy implementation. Agriculture and transport require targeted strategies to accelerate decarbonisation and foster convergence towards best practices, ensuring the EU meets its sustainable development goals.
