本研究は、プロセスレベルの会計枠組みを用いて、EUの炭素国境調整措置（CBAM）が中国鉄鋼産業に与える長期的影響を定量化した。2050年までのシナリオで、証明書コストは29億～1230億元と推定され、EU ETS価格が主要な要因である。低炭素技術の導入や中国国内炭素市場の活用により、コストの最大18.78%を相殺可能であり、国際的に比較可能な炭素会計とCBAM収入のグリーンイノベーションへの再投資の重要性を強調する。

This study develops a process-level accounting framework to quantify the long-term impact of the EU's CBAM on China's steel industry. Certificate costs are estimated at 0.29–12.3 billion CNY by 2050, with EU ETS price as the main driver. Low-carbon technologies and inclusion of steel in China's national carbon market can offset up to 18.78% of costs. The findings highlight the need for comparable carbon accounting and reinvesting CBAM revenues in green innovation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本も鉄鋼輸出においてCBAMの対象となる可能性があり、本論文の方法論は日本の鉄鋼業界の影響評価に応用できる。また、国内炭素市場とCBAMの連携や、低炭素技術投資の重要性を示唆しており、日本のGX政策や炭素価格設計に示唆を与える。
In the global GX context
This paper provides a rigorous quantification of CBAM's impact on the world's largest steel producer, offering insights for global trade and climate policy. It underscores the need for internationally comparable carbon accounting and demonstrates how national carbon markets can mitigate CBAM costs, relevant for upcoming CBAM implementation and developing economies' climate strategies.
👥 読者別の含意
🔬研究者:The process-level accounting framework and sensitivity analysis provide a methodological reference for assessing carbon border adjustments in other sectors or countries.
🏢実務担当者:Steel industry sustainability teams can use the cost estimates and mitigation scenarios to plan low-carbon technology adoption and prepare for CBAM compliance.
🏛政策担当者:Regulators in China and other developing economies should note the potential of integrating sectors into national carbon markets to offset CBAM costs and the importance of reinvesting CBAM revenues in green innovation.
📄 Abstract（原文）
Summary Mitigating climate change has become a global consensus, yet uneven carbon prices and fragmented policies raise concerns about carbon leakage and trade competitiveness. The European Union’s carbon border adjustment mechanism (CBAM) levies charges on imported goods based on embedded emissions. This study develops a process-level accounting framework to assess the long-term impacts of CBAM on China’s steel industry. Linking production routes, emission intensities, and carbon pricing, we estimate certificate costs of 0.29–12.3 billion CNY by 2050 across scenarios. Sensitivity analysis identifies the EU emissions trading system price as the primary driver, while low-carbon technologies such as direct reduced iron (DRI) and electric arc furnace (EAF) routes significantly reduce the burden. Inclusion of steel in China’s national carbon market could offset up to 11.44% of blast furnace-basic oxygen furnace (BF-BOF) and 18.78% of DRI-EAF costs. The findings highlight the importance of internationally comparable carbon accounting and reinvesting CBAM revenues into green innovation in developing economies.
