本論文は、再生可能エネルギーやCCS、効率改善だけでは不十分とし、循環経済を脱炭素の体系的補完策として位置づける。廃棄物・産業・農業・都市・エネルギー各部門でのGHG削減メカニズムを分析し、中国の産業共生ネットワークが年間1.09MtのCO₂を削減した事例などを提示。EUと中国の政策枠組み、実施障壁、バイオ素材の土地利用や炭素除去コスト（100〜1,200ドル/トン）の課題を論じる。
English
This paper positions the circular economy as a systemic complement to conventional decarbonization, arguing renewables, CCS, and efficiency alone are insufficient. It analyzes how resource efficiency, product life extension, recycling, and industrial symbiosis cut emissions across waste, industrial, agricultural, urban, and energy sectors, citing a Chinese symbiosis network cutting 1.09 Mt CO2/yr and modelling net-zero municipal waste by 2050. It reviews EU and China policy frameworks, barriers, and challenges like bio-based land-use trade-offs and carbon removal costs of $100–1,200/t.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では資源循環とカーボンニュートラルを統合する政策（循環経済工程表、GX推進法）が進む。本論文の産業共生・廃棄物由来削減の定量手法は、国内企業のScope3・サーキュラー調達戦略や自治体の脱炭素計画に応用可能。
In the global GX context
Globally, the paper bridges circular economy and climate disclosure agendas, offering quantified pathways relevant to CSRD circularity reporting, ISSB Scope 3, and transition finance. Its facility- and economy-level evidence supports integrating material flows into net-zero target-setting beyond energy-only decarbonization.

📄 Abstract（原文）
Global climate change, driven by industrialization and dependence on non-renewable energy, has made carbon neutrality an urgent international objective. This paper examines the role of the circular economy as a systemic complement to conventional decarbonization strategies. It argues that renewable energy deployment, carbon capture, and efficiency gains, while necessary, are insufficient without transforming how materials and products are produced, used, and recovered. Drawing on the concept of carbon as both an energy carrier and a material, the paper analyzes the mechanisms through which circular strategies resource efficiency, product life extension, waste valorization, recycling, and industrial symbiosis reduce greenhouse gas emissions across the waste, industrial, agricultural, urban, and energy sectors. A dedicated empirical case study section presents facility, cluster, and economy-level evidence, including an industrial symbiosis network in China that reduced CO₂ emissions by 1.09 Mt per year, equivalent to 3.63% of a city's total carbon footprint under a business-as-usual scenario. Life cycle assessment of municipal solid waste indicates average global emissions of 89.7 kg CO₂e per tonne in 2023, with open dumping contributing almost 70%, and modelling shows that circular economy implementation could achieve net-zero emissions from global municipal solid waste management by 2050. The paper concludes by discussing policy frameworks in the European Union and China, implementation barriers, and key challenges such as land-use trade-offs of bio-based materials and the high cost of carbon removal technologies, which range from $100 to $1,200 per ton of CO₂.
