日本語
本研究は、インドネシアの熱帯高地野菜（ジャガイモ、ニンジン、ネギ）のライフサイクル評価を実施し、作物ごとの排出経路と緩和優先順位を明らかにした。ジャガイモは面積当たりの排出量が最も高く、ニンジンは製品単位の排出原単位が最も高い。排出ホットスポットは作物ごとに異なり、肥料・農薬、燃料・エネルギー、現場排出がそれぞれ主要因である。作物別の緩和戦略の必要性を示す。
English
This study conducts a life cycle assessment of tropical highland vegetables (potato, carrot, green onion) in Indonesia, revealing crop-specific emission pathways and mitigation priorities. Potato has the highest emissions per hectare, while carrot has the highest per-unit product intensity. Hotspots vary: fertilizer/agrochemicals for potato, fuel/energy for carrot, and balanced for green onion. Crop-specific mitigation strategies are needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の農業分野では、SSBJやカーボンフットプリント表示の動きが進む中、作物別の排出原単位データは国内の農業生産者や食品企業にとって参考になる。特に、輸入野菜の調達先での排出削減を検討する際に、本研究成果はサプライチェーン排出量の算定に役立つ可能性がある。
In the global GX context
This study contributes to global agricultural LCA literature by providing emission data for tropical highland vegetables, a region often underrepresented. It supports the development of crop-specific mitigation strategies and can inform carbon footprint labeling initiatives in emerging economies, aligning with global sustainability reporting frameworks.

📄 Abstract（原文）
HistoryTropical highland horticulture is a significant production system that has not been sufficiently explored in life cycle assessment (LCA), despite its substantial reliance on fertilizers, agrochemicals, fuel, and electricity.This study aimed to delineate crop-specific emission pathways and establish mitigation priorities for three highland vegetables: potato, carrot, and green onion.A comparative attributional LCA was conducted with cradle-to-farm-gate system boundaries, in accordance with ISO 14040 and ISO 14044, in the Tinggimoncong Subdistrict, Gowa Regency, Indonesia, during the 2025 production season.The results indicated that potatoes exhibited the highest carbon footprint, at 6,281.15 kg CO₂-eq ha⁻¹, followed by carrots at 6,165.21 kg CO₂-eq ha⁻¹ and green onions at 5,763.07 kg CO₂-eq ha⁻¹.However, on a perunit product basis, carrots had the highest emission intensity at 0.680 kg CO₂-eq kg⁻¹, followed by green onions at 0.533 kg CO₂-eq kg⁻¹ and potatoes at 0.440 kg CO₂-eq kg⁻¹.Emission hotspots varied among crops: potato emissions were driven mainly by fertilizer and agrochemical use; carrot emissions were strongly influenced by fuel and operational energy; and green onion emissions showed a more balanced profile.These findings suggest that mitigation strategies should be crop-specific, emphasizing fertilizer and agrochemical efficiency for potatoes, energy efficiency for carrots, and on-site emission management for green onions.
