都市街区スケールの低炭素化を評価するため、エネルギー・建築・交通・廃棄物・水・炭素吸収の6領域から22の二次指標を構築し、AHPで重み付けした総合炭素削減指数（CCI）を提案。広州の一事例に適用し、2020〜2025年で総炭素排出26.61%削減、CCI 0.9924を達成。計画・評価・技術最適化を統合した全過程カーボンマネジメント枠組みの有効性を示す。
English
The study builds a two-level low-carbon neighborhood indicator system (6 domains, 22 indicators) using word-frequency analysis and expert validation, weighting them via AHP and aggregating into a composite Carbon-reduction Index (CCI). Applied to a Guangzhou block, total emissions fell 26.61% from 2020 to 2025 with CCI reaching 0.9924. It offers an operational whole-process carbon management framework for urban-block-scale planning and evaluation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では都市・街区単位の脱炭素（環境省の脱炭素先行地域、CASBEE街区、自治体実行計画）が進むが、統合指標と運用評価手法は発展途上。本論文のCCI型アプローチは、自治体・デベロッパーが街区単位の削減進捗を定量管理する際の参考設計になり得る。
In the global GX context
While global disclosure frameworks (TCFD/ISSB/CSRD) focus on corporate and asset-level emissions, this paper addresses the neighborhood scale where most urban GHG originates. Its composite index and whole-process management loop offer a template for city-level transition planning that could complement corporate Scope 3 and building-sector decarbonization reporting.

📄 Abstract（原文）
Urban areas account for approximately 70% of global greenhouse gas emissions and are central to climate governance. However, low-carbon urban-block development still lacks an integrated indicator system and an operational management method for evaluating carbon-reduction performance. This study reviews carbon-emission-related indicators from domestic and international policies, standards, and planning cases, focusing on six domains: energy, buildings, transportation, solid waste, water systems, and carbon sinks. Through word-frequency analysis and a four-step validation procedure, a two-level indicator system with six primary categories and 22 secondary indicators is developed. The analytic hierarchy process and expert scoring are used to determine indicator weights, and a comprehensive carbon-reduction evaluation index (CCI) is introduced to quantify overall performance. The method is applied to a selected block in Guangzhou, China. A whole-process carbon management framework, covering systematic planning, performance evaluation, and technical optimization, is implemented for the case area. From 2020 to 2025, total carbon emissions decreased by 26.61%, and the CCI reached 0.9924, indicating substantial aggregate improvement relative to the 2020 baseline. The results show that the proposed indicator system and CCI-based evaluation method can identify key governance priorities, measure implementation performance, and support refined low-carbon management at the urban block scale.
