トルコの三次医療機関で1300件の消化器内視鏡手技を対象に、GHGプロトコル枠組みで手技別の炭素排出を前向きに算定した。平均総排出は18.22 kg CO2e/手技で、患者輸送が70.3%を占め、単回使用アクセサリーの上流排出が内在排出の48%を占めた。治療的手技は診断的手技より内在排出・廃棄物が多い。
English
A prospective study quantified procedure-level emissions for 1,300 GI endoscopy procedures using the GHG Protocol. Mean total emissions were 18.22 kg CO2e per procedure, with patient transport dominating (70.3%) and single-use accessories comprising 48% of intrinsic emissions. Therapeutic procedures had higher intrinsic emissions and waste than diagnostic ones.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
医療機関のScope 1/2/3算定は日本でも病院・製薬・医療機器メーカーの開示対応で重要性が増す。手技レベルでの排出内訳は、医療系サプライチェーンのScope 3把握や単回使用器材の調達判断に示唆を与える。
In the global GX context
Healthcare decarbonization is an emerging frontier in global disclosure, with hospitals and medical suppliers increasingly expected to report Scope 3 under CSRD and ISSB. This procedure-level LCA offers a replicable methodology for clinical settings, though single-center and partial-boundary limits apply.
👥 読者別の含意
🔬研究者:医療分野の手技レベルLCA手法と排出内訳の実証例として参考になる。
🏢実務担当者:医療機関・医療機器メーカーがScope 3算定や単回使用器材の調達見直しに活用できる。
🏛政策担当者:医療部門の排出削減政策や開示要件設計の基礎データとして留意。
📄 Abstract（原文）
Objective: Gastrointestinal endoscopy (GIE) contributes to healthcare-related greenhouse gas emissions; however, prospective procedure-level data remain limited. This study quantified procedure-level emissions and waste and examined operational factors associated with intrinsic (non-transportation-related) emissions. Methods: This prospective environmental study included 1300 consecutive GIE procedures performed in adults at a tertiary referral center. Activity data included electricity, water, carbon dioxide insufflation, supplemental oxygen, selected single-use accessories, waste, and patient transportation. A partial cradle-to-gate life-cycle assessment was performed for 4 accessory categories. Emissions were calculated within the Greenhouse Gas Protocol framework. Exploratory multivariable regression examined associations with intrinsic emissions. Results: Mean total emissions were 18.22 ± 4.10 kg CO2e per procedure. Patient transportation was the largest contributor (12.81 kg CO2e; 70.3%). Mean intrinsic emissions were 5.41 ± 1.80 kg CO2e per procedure. Modeled upstream emissions from 4 accessory categories contributed 2.60 kg CO2e, representing 48.0% of intrinsic and 14.3% of total emissions. Therapeutic procedures had higher intrinsic emissions than diagnostic procedures (7.01 ± 2.40 vs 4.41 ± 1.50 kg CO2e; P < .001) and generated more waste (1.20 ± 0.30 vs 0.60 ± 0.20 kg; P < .001). Longer procedure duration and greater modeled accessory use were associated with higher intrinsic emissions; procedure category was not associated after adjustment. The model explained 68% of the variance (adjusted R2 = 0.68). Conclusion: Patient transportation dominated total emissions, whereas the 4 modeled single-use accessory categories constituted the largest intrinsic component. Findings should be interpreted within the single-center and partial life-cycle boundaries. Cite this article as: Özden Y, Kaldırım Armutçuoğlu Y, Kani HT.
