本研究は、インドネシア・タンジュン・レデブの4つの都市緑地を対象に、車両走行距離モデルと種別アロメトリー式を用いて、交通由来CO2排出量と植物の炭素隔離能力を比較評価した。結果、すべての公園で正味炭素収支がプラスであったが、排出ホットスポットと高吸収能の緑地が空間的に乖離していることが明らかになった。高吸収種であるサマネア・サマンを排出源近くに戦略的に配置するなど、データに基づく生物工学的アプローチの重要性が示された。
English
This study evaluates four green open spaces in Tanjung Redeb, Indonesia, comparing vehicular CO2 emissions (VKT model) with species-specific carbon sequestration. All parks showed net positive carbon surplus, but severe source-sink decoupling was found, with high-emission areas lacking high-capacity vegetation. The study advocates for data-driven biological engineering using hyper-accumulator species like Samanea saman along transport corridors.

日本のGX文脈において
本論文は直接日本のGX政策に関連しないが、都市緑地の炭素吸収源としての評価手法は、日本の都市計画や「地域脱炭素ロードマップ」におけるグリーンインフラ活用に示唆を与える。今後、自治体がSSBJに基づく気候変動適応策を検討する際の参考となる可能性がある。
In the global GX context
This paper contributes to the global discourse on nature-based solutions for climate mitigation, offering a replicable methodology for urban carbon sink assessment. Its findings on species-specific sequestration capacity are relevant for city-level climate action plans, especially where TCFD/ISSB-aligned disclosure may include nature-based offsetting.

📄 Abstract（原文）
Rapid urbanization escalated domestic vehicular CO₂ emissions, necessitating the optimization of urban green open spaces (GOS) as engineered biological sinks. However, urban planning practices frequently prioritized spatial area over species-specific sequestration capacity, leading to potential spatial inefficiencies. This study evaluated the efficacy of four GOS in Tanjung Redeb, Indonesia, by overlaying localized vehicular emission loads—calculated using the Vehicle Kilometer Traveled (VKT) model—with the biological sequestration capacities of the parks, quantified through species-specific allometric equations. The results indicated that all evaluated parks operated at a net positive carbon surplus, with absorption ratios ranging from 1,474.8% to 117,668.6%. Crucially, the empirical data exposed a severe source–sink decoupling. The primary emission hotspot, Taman Bukit Maritam (1,032.33 kg CO₂/year), relied on moderately performing vegetation, yielding the lowest relative surplus. Conversely, the highest sequestration capacity (37,010.96 kg CO₂/year) was located in Taman Sanggam, a low-stress corridor (92.33 kg CO₂/year), driven by the aggressive structural biomass of the hyper-accumulator Samanea saman. The analysis demonstrated that biological filtration performance was strictly dictated by species taxonomy and allometric structure, rather than stand age or total park area. The study concluded that mitigating urban vehicular emissions required a paradigm shift from passive aesthetic landscaping to active, data-driven biological engineering, deploying high-capacity hyper-accumulators strategically along high-emission transportation corridors.
