| 内容記述 | Urban green infrastructure plays a vital role in mitigating heat and reducing cooling energy demand. This study examines how declining tree canopy cover impacts cooling energy use, using Utsunomiya Universityʼs Mine Campus (Japan) as a case study. Between 2022 and 2025, the campusʼs canopy coverage declined from approximately 25.0% to 17.5%, mainly due to tree removal for safety and development purposes. Canopy rates were estimated through LiDAR data, satellite imagery, and field verification. Combined with meteorological and electricity usage data, the analysis revealed that a 7.5-point decrease in canopy cover increased cooling energy demand by approximately 4.5%, based on the Tokyo Model (Meili et al., 2025). This translated into an estimated annual rise in electricity costs of about 6.25 million yen and approximately 120 tons of additional CO₂ emissions. Moreover, the removal of about 200 mature trees resulted in the loss of around 180 tons of carbon stock, creating a combined climate impact of roughly 300 tons of CO₂. Comparative analysis with another campus (Yoto Campus), which maintained stable tree cover, further confirmed the substantial influence of canopy loss on energy efficiency. The study also addresses governance challenges, highlighting how tree removal decisions often exclude discussions of long-term environmental and economic impacts. It calls for reflexive governance frameworks that integrate interdisciplinary knowledge and stakeholder participation, especially when managing nature-based solutions (NbS). This research underscores that urban greenery should not be viewed merely as landscape or ecology, but as essential climate-adaptive infrastructure. Strategic canopy management can significantly affect institutional energy efficiency, economic performance, and environmental resilience. | |||||||||||||||||||||||
