本レビューは、都市のブルー・グリーン・グレーインフラ（BGGI）による炭素削減と暑熱レジリエンスに関する研究を統合し、直接的な炭素貯留・隔離と微気候調整を通じた運用排出削減を区別している。空間分析・リモートセンシング、モデルシミュレーション、機械学習、LCA・LCC・CBAなどの評価手法を整理し、要素の断片化、生態系サービスの統合不足、時空間的範囲の制約、エンボディドカーボンの考慮不足といった課題を指摘する。より統合的な評価枠組みと一貫した炭素会計の必要性を提唱している。
English
This review synthesizes research on urban blue-green-grey infrastructure (BGGI) for carbon reduction and heat resilience, distinguishing direct carbon storage/sequestration from operational emission cuts via microclimate regulation. It maps methods—spatial analysis, remote sensing, simulation, machine learning, LCA/LCC/CBA—and identifies gaps: fragmented treatment of elements, weak ecosystem-service integration, limited spatiotemporal coverage, and incomplete embodied-carbon accounting. It calls for more integrated assessment frameworks and consistent carbon accounting to support low-carbon spatial planning.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では都市緑化・ヒートアイランド対策・脱炭素先行地域など自治体主導の施策と親和性が高い。SSBJや有報でのScope 3・気候リスク開示に直結はしないが、不動産・建設セクターの気候適応・炭素会計の基礎資料となりうる。
In the global GX context
Globally, this speaks to the adaptation side of climate disclosure (TCFD/ISSB physical risk) and to urban transition finance, where cities and real-estate firms must quantify both mitigation and resilience co-benefits. It highlights the methodological gap that keeps nature-based and grey infrastructure out of consistent carbon accounting.

📄 Abstract（原文）
Urban blue-green-grey infrastructure (BGGI) is increasingly discussed as a strategy for reducing carbon emissions and improving heat resilience, but evidence on its mechanisms and assessment methods remains fragmented. This review synthesizes BGGI studies retrieved from Web of Science and ScienceDirect, focusing on carbon reduction pathways, analytical approaches and unresolved assessment challenges. The review distinguishes direct carbon storage and sequestration in blue-green components from operational emission reduction linked to microclimate regulation and changes in building energy demand. It also considers the life-cycle carbon effects of grey infrastructure design and retrofitting. Existing studies use spatial analysis and remote sensing for observation, model simulation for scenario assessment, whereas machine learning supports prediction and model-based interpretation. Life-cycle assessment (LCA), life-cycle costing (LCC), and cost-benefit analysis (CBA) are used for environmental and economic evaluation. However, most assessments remain limited by fragmented treatment of infrastructure elements, insufficient integration of multiple ecosystem services, restricted spatial and temporal coverage, and incomplete consideration of embodied carbon and service-life differences. Comparative evidence across climate zones and seasons is also limited, making it difficult to evaluate trade-offs among cooling benefits, carbon sequestration and energy demand. The review identifies the need for more integrated assessment frameworks and more consistent carbon accounting. These advances could strengthen the theoretical and methodological support for low-carbon spatial planning and more precise urban decision making.
