本論文は、2025年春に表明された英国ETSとEU ETSの連携構想を巡り、制度面の実現可能性を市場設計・政治経済・経済・環境の4次元で評価する。両制度には高い制度的互換性があり、流動性向上や排出削減の効率化、炭素価格の信認向上、CCS・GHG除去市場での協力深化といった便益が期待される。一方、ガバナンスや規制自治への懸念が障壁となり、長期的成功には継続的な越境政策調整が必要と結論づける。
English
This paper assesses the feasibility of linking the UK and EU Emissions Trading Schemes, following the Spring 2025 announcement of intent to establish a link. Evaluating market design, political economy, economic, and environmental dimensions, it finds strong institutional compatibility and benefits including greater liquidity, more efficient abatement, more credible carbon prices, and cooperation on CCS and engineered GHG removals. Governance and regulatory autonomy concerns remain barriers requiring sustained cross-jurisdictional coordination.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではGX-ETSと排出量取引制度の本格稼働、炭素価格付けの制度設計が進む中、英国・EUの連携交渉は「制度接続」の現実的課題（市場設計の互換性、規制自治、価格信認）を示す先行事例として参考になる。東アジアや国際クレジット連携を視野に入れる日本にとって、リンクの便益と障壁の整理は政策対話の材料となる。
In the global GX context
As ISSB/CSRD disclosure and carbon pricing converge, this paper speaks directly to the global debate on ETS linkage and Article 6 cooperation, offering a structured four-dimension framework for assessing compatibility between jurisdictions. It adds timely post-Brexit empirical grounding to transition-finance and carbon-market-integration scholarship relevant to regulators designing cross-border carbon markets.
👥 読者別の含意
🔬研究者:ETSリンクの制度的互換性を4次元で評価する分析枠組みは、他地域の炭素市場統合研究に応用できる。
🏢実務担当者:炭素価格の信認向上やCCS・除去市場の拡大は、長期の脱炭素投資計画やカーボンクレジット調達戦略の前提条件となりうる。
🏛政策担当者:制度接続における規制自治とガバナンスの調整課題は、GX-ETSや国際クレジット連携の設計に直接示唆を与える。
📄 Abstract（原文）
Adopting climate-neutral and net-zero emissions targets is central to many nations' climate strategies aimed at mitigating climate change effects and promoting sustainable low-carbon transitions. Emissions trading schemes (ETSs) serve as a key policy mechanism, with linked systems enabling international cooperation. With the intention to establish a UK-EU ETS link announced in Spring 2025, this paper examines institutional factors facilitating or constraining implementation, alongside its potential contribution to UK net-zero objectives. It contributes to discussions surrounding UK-ETS linkage by evaluating ETS compatibility literature alongside post-Brexit climate policy. We identify and assess the feasibility of linking ETSs based on four dimensions: market design, political economy, economic, and environmental considerations. Our analysis reveals strong institutional compatibility between the UK and EU ETS. Linkage offers significant benefits including enhanced market liquidity, more efficient emissions abatement, greater carbon price credibility, and improved cooperation on emerging areas like engineered greenhouse gas removals and carbon capture and storage markets. A linked ETS could strengthen policy alignment between UK-EU climate policies, particularly regarding carbon capture and storage, greenhouse gas removals, and broader decarbonisation investments. However, governance and regulatory autonomy concerns, coupled with evolving market design ambitions, pose barriers requiring sustained cross-jurisdictional policy coordination for long-term success.
