日本語

この系統的レビューは、エネルギー分野の循環経済(CE)移行における持続可能なビジネスモデルとグリーンファイナンスの共進化を分析。93の研究を統合し、EUタクソノミーやグリーンボンドが循環投資のリスク軽減に果たす役割を評価。ブロックチェーンやAIの活用可能性と規制の断片化という課題を指摘し、「規制-技術的接合」の研究枠組みを提案する。

English

This systematic review of 93 studies examines the co-evolution of circular business models and green finance in the energy sector. It finds a shift toward higher-order circularity and analyzes the role of EU Taxonomy, green bonds, and crowdfunding. It identifies the transparency paradox and efficiency-waste trade-off, and proposes a regulatory-technical nexus for future research.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

本論文はEUタクソノミーやグリーンボンドなど、日本でもGXリーグやグリーンボンドガイドラインで導入が進む金融メカニズムを体系的にレビューしており、日本のGX政策や企業の循環型ビジネスモデル構築に示唆を与える。

In the global GX context

This paper provides a timely synthesis of circular business models and green finance mechanisms, with a focus on the EU Taxonomy. It highlights regulatory fragmentation and the need for digital tools like circular digital twins, offering valuable lessons for global jurisdictions (e.g., ISSB, SEC) working on transition finance frameworks.

👥 読者別の含意

🔬研究者:This review maps the landscape of circular business models and green finance in energy, identifying research gaps such as the need for empirical validation of digital tools and standardized decommissioning protocols.

🏢実務担当者:Corporate sustainability teams can use the 10R framework to assess circularity options and understand the applicability of green bonds and EU Taxonomy for de-risking circular investments.

🏛政策担当者:The paper highlights regulatory fragmentation and the transparency paradox in second-life markets, suggesting a need for harmonized standards and circular digital twins to accelerate the energy transition.

📄 Abstract（原文）

The energy sector’s transition to a circular economy (CE) is critical for achieving global decarbonization and resource security. The primary objective of this systematic literature review is to examine the co-evolution of circular business models (CBMs) and green financing mechanisms across the energy value chain. To achieve this, we synthesized 93 high-impact studies published between 2015 and 2024, which were retrieved from the Web of Science and Scopus databases. Using the 10R hierarchy as an analytical framework, this study identifies a strategic shift from low-order recycling to high-value circularity, such as rethink, repurpose, and remanufacture. We analyze the role of the EU Taxonomy, green bonds, and equity crowdfunding in de-risking circular investments, while highlighting the “transparency paradox” in second-life markets and the “efficiency-waste trade-off” in rapid technological turnovers. Our findings reveal that while digital catalysts like blockchain and AI optimize resource flows, their scaling is hindered by a lack of empirical validation and fragmented regulations. The review concludes by proposing a “regulatory-technical nexus” for future research, emphasizing the need for circular digital twins and standardized decommissioning protocols to bridge the gap between theoretical optimization and operational reality in the renewable energy sector.
