EUは2026年から炭素国境調整メカニズム(CBAM)を導入し、輸入品に炭素価格を課す。これによりEU ETSの炭素漏出問題に対処し、排出削減と産業競争力の両立を図る。本稿はETSとCBAMが企業の供給選択に与える影響を定量分析する。
English
The EU will implement the Carbon Border Adjustment Mechanism (CBAM) by 2026, imposing a carbon tariff on imports to prevent carbon leakage from the EU ETS. This analysis quantifies how the ETS and CBAM affect firms' supply choices, domestic prices, and emissions, highlighting the policy's impact on trade and decarbonization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EUのCBAMは2026年から適用予定で、日本企業のEU向け輸出に直接影響する。日本国内のカーボンプライシング議論（GXリーグ等）にも示唆を与え、将来的な日本のCBAM導入の先行事例として重要。
In the global GX context
The EU's CBAM is a landmark policy for global carbon pricing and trade, affecting international supply chains. It sets a precedent for other regions considering border carbon adjustments, and its design and effectiveness provide key insights for global climate policy and corporate carbon management.
👥 読者別の含意
🔬研究者:Provides a quantitative framework for analyzing firm-level responses to carbon border adjustments, useful for trade and climate policy research.
🏢実務担当者:Highlights the need for companies exporting to the EU to prepare for CBAM reporting and potential cost impacts on carbon-intensive goods.
🏛政策担当者:Offers evidence on CBAM's effectiveness in curbing carbon leakage and its implications for designing domestic carbon pricing and border measures.
📄 Abstract（原文）
The European Union has been an early adopter of carbon policies, with the introduction of the EU Emissions Trading System (ETS) in 2005. This scheme sets a common price for carbon and is applied to the most polluting manufacturing sectors. By increasing the cost of emissions-intensive production, the system incentivizes firms to decrease their use of fossil fuels. However, as we show in a companion post, the policy’s impact was moderated by firms increasing their reliance on high-emissions imports. To eliminate this workaround, the EU will expand the ETS to imports in 2026, through the Carbon Border Adjustment Mechanism (CBAM). The CBAM will essentially put a tariff on imported goods based on their carbon content. Our recent work provides a quantitative analysis of how the ETS and CBAM affect firms’ supply choice decisions, and the resulting changes in domestic prices and emissions.
