日本語

本論文は、EUのCBAM(炭素国境調整メカニズム)を気候正義の観点から批判的に分析。CBAMの現行設計は炭素コストの均等化に偏り、発展途上国の異なる能力や非価格政策を軽視していると指摘。公平な炭素コスト差別化への移行と、差別化されたコンプライアンス経路、技術支援、途上国への収益還流を提案する。

English

This paper critically analyzes the EU's Carbon Border Adjustment Mechanism (CBAM) from a climate justice perspective. It finds that CBAM's current design overly focuses on carbon cost equalization and inadequately recognizes differentiated capacities and non-price policies. It recommends moving toward equitable carbon-cost differentiation, including differentiated compliance pathways, technical assistance, and revenue recycling for developing countries.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

EU-CBAMは日本企業の対EU輸出に直接影響する。本論文は気候正義の観点からCBAMの制度的課題を整理しており、日本が今後導入を検討するカーボンプライシング制度の設計や、SSBJ開示との関連性を考察する上でも示唆に富む。

In the global GX context

CBAM is a key instrument in EU climate policy with global trade implications. This paper provides a legal framework evaluating CBAM beyond competitiveness, integrating equity and CBDR-RC principles - relevant for global discussions on carbon pricing and trade law compatibility, including in ISSB and WTO contexts.

👥 読者別の含意

🔬研究者:Offers a critical legal framework integrating climate justice with carbon border adjustment for scholars studying trade-climate intersections.

🏢実務担当者:Highlights compliance pathways and cost implications for EU importers; useful for corporate sustainability teams managing CBAM exposure.

🏛政策担当者:Provides recommendations on equitable CBAM design, including differentiated compliance and revenue recycling, for trade and climate negotiators.

📄 Abstract(原文)

The Carbon Border Adjustment Mechanism (CBAM) raises urgent legal questions about whether climate ambition pursued through border measures can be reconciled with equity and common but differentiated responsibilities and respective capabilities (CBDR-RC), and sustainable development. While Mehling et al. (2019) examine border carbon adjustments as tools for enhanced climate action and trade-law legitimacy, Beaufils et al. (2023) assess their distributional impacts on trade partners, and Boute (2024) analyses the recognition of third-country carbon pricing, these studies remain insufficiently integrated in explaining CBAM simultaneously as a climate-target instrument and a justice-sensitive legal mechanism. This article aims to critically assess whether CBAM can prevent carbon leakage and extend carbon pricing to imports without imposing disproportionate transition burdens on developing countries and carbon-intensive exporters. It employs normative legal research using statutory, conceptual, and critical policy approaches, focusing on Regulation (EU) 2023/956, international climate law, WTO-related principles, and climate justice scholarship. The article finds that CBAM may strengthen carbon accountability and protect the integrity of EU climate policy, but its current design remains overly centred on carbon-cost equalisation and gives inadequate recognition to differentiated capacities, non-price climate policies, procedural participation, and revenue equity. It concludes that CBAM should move from equal carbon pricing toward equitable carbon-cost differentiation. The article recommends differentiated compliance pathways, recognition of diverse mitigation measures, technical assistance, and revenue recycling for affected developing countries. Its contribution lies in offering foreign readers a critical legal framework for evaluating CBAM beyond EU competitiveness, as a test of fairness in global climate-trade governance.
