本研究は、中国の都市レベルで廃棄物と炭素排出の結合調整を評価。メガロポリスは消費ハブとして廃棄物・炭素を外部化するが、高い結合調整を示す。消費側からの調整度は生産側より20.4-68.8%高く、最終需要の重要性が明らかに。2015-2019年、中小都市で有害廃棄物と炭素の調整度が18.4%上昇。

This study provides a novel city-level assessment of the coupling coordination between waste and carbon emissions in China. Megalopolises outsource waste and carbon but maintain high coordination. Consumption-based coordination is 20.4-68.8% higher than production-based, highlighting demand-side leverage. Between 2015-2019, coordination in small/medium cities increased by 18.4% for hazardous waste and carbon.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国都市を対象とするが、廃棄物と炭素の統合管理の枠組みは日本の自治体や企業にも示唆を与える。特にサプライチェーン全体での環境負荷の把握は、Scope 3 排出量算定やゼロウェイスト政策と親和性が高い。
In the global GX context
This paper offers a novel method for city-level coupling coordination analysis of waste and carbon, relevant for integrated governance globally. It emphasizes demand-side strategies, which align with Scope 3 thinking and circular economy policies. The findings are particularly useful for countries like China and also for global supply chain decarbonization efforts.

🔬研究者:The coupling coordination index and consumption-based perspective provide methodological advances for urban-industrial ecology research.
🏢実務担当者:Companies can use the demand-side insights to identify upstream environmental pressures in their supply chains and prioritize source reduction.
🏛政策担当者:The results support integrated policies for carbon neutrality and zero-waste cities, highlighting the need for consumption-oriented measures.
📄 Abstract（原文）
Waste management and carbon emission reduction, both central to the Sustainable Development Goals, are increasingly encouraged to be integrated due to the strong and inherent linkages between waste generation and greenhouse gas emissions. A system-wide understanding of this relationship across the entire supply chain, from production to final consumption, is fundamental for identifying leverage points for source reduction. This study provides a novel city-level assessment of the coupling coordination between waste and carbon emissions in China. The results reveal that, although megalopolises act as consumption hubs, benefiting from reduced local generation of hazardous waste, industrial solid waste, and carbon emissions through outsourced production, they still exhibit consistently high coupling coordination between carbon and waste emissions. Furthermore, demand-side strategies are equally critical because coupling coordination is 20.4-68.8% higher from the consumption perspective than from the production perspective, underscoring the decisive role of final demand in driving upstream environmental pressures. Between 2015 and 2019, the average coordination between hazardous waste and carbon emissions from a production perspective increased by 18.4%, whereas other coordination indicators remained relatively stable. The strengthening was particularly pronounced in medium and small cities, where increases in hazardous waste and carbon intensities were the primary drivers, outweighing the influence of sectoral output changes. These findings provide a foundation for integrated environmental governance to support both carbon neutrality and zero-waste development goals.
