循環経済（CE）対策は温室効果ガス排出削減に貢献できるが、気候変動緩和モデルでの表現は不十分。本レビューでは、CE戦略のGHG削減可能性に関する実証的証拠と現在のモデリング手法を調査。リサイクルに集中する研究が多いが、材料代替や再利用設計への注目が高まっている。リフューズ、リシンク、行動要因、リバウンド効果、気候政策とのシナジー・トレードオフにはギャップが残る。産業エコロジー手法とGHG緩和モデルの連携強化が必要。
English
This review examines the empirical evidence and modelling approaches for circular economy (CE) strategies in climate change mitigation. It finds that while most studies focus on recycling, upstream strategies like material substitution and reuse design are gaining attention. Gaps remain in Refuse, Rethink, behavioral factors, rebound effects, and policy synergies. Better alignment between industrial ecology and GHG mitigation models is needed to support policy-relevant assessments.

📄 Abstract（原文）
Circular economy (CE) measures can play a role in reducing greenhouse gas (GHG) emissions, especially in material- and energy-intensive sectors. Yet, their representation in GHG mitigation pathways is still not well captured in climate change mitigation models. To support modelling efforts towards better CE representation, two reviews were conducted: (1) the empirical evidence on the GHG mitigation potential of CE strategies across material supply and demand sectors and R-strategies, and (2) the current modelling approaches used to assess these strategies. Findings show that, while most studies focus on recycling, increasing attention is given to upstream strategies such as material substitution, design for reuse, and service-based business models. Important gaps remain, particularly around Refuse, Rethink, behavioural factors, rebound effects, as well as synergies and trade-offs with climate policy. Industrial ecology methods provide a detailed material flows representation but lack feedback mechanisms and economic dynamics. In contrast, GHG mitigation models offer broader system coverage but often simplify materials and CE dynamics. Better alignment between methods is needed, including shared definitions, improved data, and more collaboration across modelling communities. Strengthening the modelling of CE strategies can support policy-relevant assessments of CE’s contribution to achieving global climate goals.
