日本語
本博士論文は、CCUS技術を社会・政治・経済の三次元から捉え、フィンランド・バルト三国の事例を通じて、その展開が規制の不確実性と政策支援への依存に阻まれていることを示す。CCUSは化石燃料システムの縮小と再生可能エネルギー拡大をつなぐ一時的な被害抑制策と位置づけ、気候変動緩和は技術だけでは解決できない広範な課題だと結論づける。
English
This dissertation examines CCUS as a sociotechnical phenomenon across social, political and economic dimensions, drawing on Finnish media discourse and policy interviews in Finland and the Baltics. It finds regulatory uncertainty and heavy reliance on policy support are key barriers to commercial deployment, concluding CCUS is best understood as a temporary damage-control bridge between a winding-down fossil system and a scaling-up renewable one.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではCCUSはGX推進法やエネルギー基本計画で重要技術と位置づけられるが、本論文は規制不確実性と政策依存という実装課題を欧州事例から示し、日本企業のCCUS事業化検討や政策設計に示唆を与える。SSBJ開示との直接接続は薄いが、移行計画における技術前提の妥当性を問う材料となる。
In the global GX context
Globally, CCUS features in many net-zero strategies and transition plans, yet this work highlights the persistent gap between projected potential and actual deployment. It adds a sociotechnical, policy-focused perspective to disclosure scholarship by showing why CCUS business cases remain policy-dependent, relevant to ISSB/CSRD transition-plan credibility debates.
👥 読者別の含意
🔬研究者:CCUSを社会技術システムとして捉える分析枠組みと、バルト海地域の政策・世論データを提供する。
🏢実務担当者:CCUS事業のビジネスケースが政策支援に強く依存することを踏まえ、規制動向のモニタリングと移行計画での技術前提の精査に活用できる。
🏛政策担当者:CCUSの商業展開には規制の明確化と安定した支援策が不可欠であることを示唆する。
📄 Abstract（原文）
The increasing concentration of atmospheric carbon dioxide, driven primarily by industrial activity and fossil fuel use, has made climate change mitigation one of the most urgent challenges of our time. Carbon capture, utilisation and storage (CCUS) technologies have been recognised as important tools in climate change mitigation, but their deployment has consistently fallen short of projected potential. Rather than examining CCUS technologies solely from an engineering perspective, in this dissertation, CCUS technologies are viewed through three dimensions: social, political and economic. This dissertation aims to provide a systemic outlook to CCUS technologies as a sociotechnical phenomenon and find out what role they play in climate change mitigation. This dissertation adopts a qualitative approach and synthesises three individual publications. Publication I investigates public attitudes towards CCUS technologies through Finnish media discourses, uncovering a cautiously positive attitude atmosphere. Publication II utilises a policy cycle approach to examine the regulatory and policy dimensions of CCUS technologies in Finland, Estonia, Latvia and Lithuania through interviews, revealing that regulatory uncertainty is a key barrier to commercial deployment. Publication III critically examines the gap between the projected potential and actual deployment of CCUS technologies and explores the business potential of the technologies through document analysis and interviews, finding that the business case is currently highly reliant on policy support. Overall, the findings of this dissertation suggest that CCUS technologies are best understood as a temporary damage-control measure, bridging a fossil fuel system that must wind down and a renewable energy system that must scaleup. The dissertation contributes to the literature by advancing understanding of CCUS technologies as a sociotechnical phenomenon. The dissertation concludes that climate change mitigation is a wider issue than what technologies alone could fix.
