中国福建省の遊休農村建築物をグリーン農村センター（GRC）として転用する枠組みを提案。省エネルギー改修により、運営エネルギー需要を50～70%削減し、新築と比較して埋込炭素を40%以上削減可能。約6万8千校の遊休校舎の30%を改修した場合、2060年までに累積約73万トンのCO2削減が見込まれる。
English
This study proposes a framework for converting idle rural buildings into Green Rural Centers (GRCs) in Fujian, China. Retrofitting can reduce operational energy demand by 50–70% and embodied carbon by ≥40% versus new construction. Retrofitting 30% of ~68,000 idle rural schools could cumulatively reduce CO2 by ~734,400 metric tons by 2060.

日本のGX文脈において
日本の中山間地域における空き家・遊休施設の再生策として参考になる。ただし、中国の政策枠組み（農村振興）に基づいており、日本のGX文脈（SSBJ、有報、投資家対応）との直接的な接点は限定的。
In the global GX context
This paper provides a replicable framework for low-carbon rural regeneration through building reuse, relevant globally for countries facing rural depopulation and idle building stock. It offers quantitative carbon reduction estimates and a policy-integrated approach that could inform ISSB-aligned infrastructure disclosures or transition finance criteria for building retrofits.

📄 Abstract（原文）
The sustainable transformation of idle built environments represents a critical pathway for advancing low-carbon development and achieving carbon neutrality targets. This study examines how idle rural building stocks may contribute to sustainable built environment systems through rural building repurposing and regeneration strategies. It introduces the concept of Green Rural Centers (GRCs), multifunctional facilities formed through the adaptive reuse of idle buildings that integrate low-carbon design, community services, and local economic functions. Within the proposed framework, GRCs are conceptually characterized as facilities that may: (1) achieve 50–70% reductions in operational energy demand through passive and renewable measures, (2) incorporate two or more community-oriented functions (e.g., education, governance, cultural services), and (3) demonstrate embodied carbon savings of ≥40% compared to demolition-and-rebuild scenarios. Grounded in fieldwork from Fujian Province, China, and aligned with national policies, the study evaluates spatial transformation, carbon mitigation, and institutional integration. Using a mixed-methods approach that combines scenario-based carbon-reduction estimation and appraisal, spatial analysis, comparative case studies, and policy evaluation, the findings indicate that retrofitting 30% of approximately 68,000 idle rural schools could achieve approximately 734,400 metric tons of cumulative CO2 reduction by 2060 under the baseline scenario. Under conservative and ambitious implementation conditions, the estimated cumulative reductions are approximately 408,000 and 1,224,000 metric tons of CO2, respectively. Sensitivity analysis shows that moderate improvements in retrofit quality or implementation rates significantly amplify emissions reduction outcomes. Beyond environmental performance, the proposed framework may also support community resilience, decentralized service provision, and socio-economic revitalization. This research reframes idle building stock as a strategic asset within sustainable built environment systems, policy-relevant exploratory framework potentially adaptable to comparable rural contexts. This study contributes to the sustainable built environment discourse by demonstrating how underutilized rural building stocks can function as broader low-carbon rural regeneration systems.
