本レビューは、都市再生の文脈における都市形態と炭素排出の関係を、100以上の実証研究から体系的に整理。コンパクトシティは中小都市で排出削減に有効だが、大都市では逆効果となる可能性があること、建物高さ等の3次元指標は運用時排出にU字効果を示すこと等を明らかにした。ライフサイクル全体を扱う研究は少なく、今後の研究課題を提示。
English
This review systematically examines the relationship between urban morphology and carbon emissions under urban renewal, drawing on over 100 empirical studies. Key findings include spatial heterogeneity and nonlinearity in the impact, with compactness reducing emissions in small-medium cities but potentially increasing them in large metropolises, and a U-shaped effect of three-dimensional metrics on operational emissions. The study highlights the lack of full life-cycle assessments and provides theoretical and practical insights for low-carbon urban strategies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、2050年カーボンニュートラル達成に向け、都市再生事業における脱炭素化が急務。本レビューは、コンパクトシティ政策や建築規制の効果を検証する際のエビデンスとして活用でき、特に三大都市圏と地方都市で異なる対策が必要な点が示唆される。
In the global GX context
Globally, urban areas account for over 70% of CO2 emissions, making urban form a critical lever for climate mitigation. This review provides a comprehensive framework linking urban morphology to carbon emissions across life-cycle stages, informing international efforts such as the UN's Sustainable Development Goal 11 (sustainable cities) and the Global Covenant of Mayors for Climate & Energy.
👥 読者別の含意
🔬研究者:Urban planning and climate researchers can use the synthesized evidence on morphology-emission linkages and the identified gaps in life-cycle assessment to guide future studies.
🏢実務担当者:Urban planners and local governments can apply the insights on compactness and 3D indicators to design low-carbon renewal projects, adjusting strategies by city size and climate zone.
🏛政策担当者:Policymakers in urban development and climate mitigation can leverage the findings to tailor zoning and building regulations that optimize carbon reduction across different city scales.
📄 Abstract（原文）
The greenhouse effect poses a severe environmental challenge to global sustainable development. Carbon emissions, as a major source of greenhouse gases, make their reduction a crucial goal of urban renewal. This paper provides a systematic literature review of over 100 empirical studies published in the Web of Science over the past decade. The results show that the impact of urban form on carbon emissions exhibits spatial heterogeneity and nonlinearity, while urban compactness reduces emissions in small and medium-sized cities but may increase emissions in some large mega cities. Meanwhile, three-dimensional morphological indicators (e.g., building height, sky view factor) exhibit a U-shaped effect on operational carbon emissions, and are primarily mediated by local microclimate effects. In addition, this study also summarized the differences in carbon emissions throughout the entire life cycle of urban renewal and across different climate zones. Only a few studies adopt a full life-cycle assessment, and most of them focused on operational rather than embodied carbon. This review credits itself as the first one of its kind to examine the relationship between urban form, urban function, and carbon emissions from the perspective of urban renewal, providing both theoretical reference and practical insights for low-carbon strategies.
