インドのAIG病院でIBD診断の手技別炭素排出量とコストを前向きに定量化した研究。検査1件あたり0.462kgからMRIの21.25kg CO2eまで幅があり、腸管超音波（IUS）は0.850kgで最低炭素・最低コストの画像診断だった。臨床的に適切な場合にIUSへ代替すると大腸内視鏡で78%、MRエンテログラフィで96%の排出削減が可能と試算。
English
Prospective study at AIG Hospitals, India, quantifying per-procedure carbon emissions and costs of IBD diagnostics. Emissions ranged from 0.462 kg CO2e per lab test to 21.25 kg CO2e per MRI; intestinal ultrasound (IUS) was the lowest-carbon imaging modality at 0.850 kg CO2e. Substituting IUS where clinically appropriate could cut emissions by 78% versus colonoscopy and 96% versus MR enterography.

📝 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排出量算定は日本でも病院のサステナビリティ報告で関心が高まりつつあるが、診断手技単位の炭素原単位データは国内に乏しく、医療系GX開示の基礎データとして参考になる。
In the global GX context
Adds granular per-procedure emissions factors for healthcare, a sector largely absent from TCFD/ISSB disclosure practice; supports the emerging 'sustainable healthcare' angle in CSRD-era reporting where Scope 3 of medical supply chains is under scrutiny.
📄 Abstract（原文）
ABSTRACT Background Healthcare contributes 4.4%–5% of global greenhouse gas emissions. Inflammatory bowel disease (IBD) requires repeated diagnostic investigations throughout a patient's lifetime, adding to healthcare's environmental footprint. However, the carbon footprint and cost of IBD diagnostic modalities have not been systematically compared Aims To quantify per‐procedure emissions and relative costs of IBD diagnostics and model potential savings from intestinal ultrasound (IUS) when clinically appropriate. Methods This prospective observational study quantified operational emissions at AIG Hospitals, Hyderabad, India, during December 2025 using the Greenhouse Gas Protocol, institutional data, and a three‐state power model. Procedures included laboratory tests (27,330), colonoscopy/enteroscopy (1290), CT (1520), MRI (589), and IUS (923). Sensitivity analyses were performed to assess the robustness of emission estimates by varying assumptions regarding infrastructure allocation, equipment power consumption, procedure volumes, and electricity grid emission factors. Results Emissions ranged from 0.462 kg CO 2 e per laboratory test to 21.25 kg CO 2 e per MRI. IUS (0.850 kg CO 2 e) was the lowest‐carbon imaging modality, with 4.6‐, 6.8‐, and 25.0‐fold lower emissions than colonoscopy/enteroscopy, CT, and MRI, respectively. Cross‐sectional imaging contributed 53.7% of total emissions (39,778 kg CO 2 e), versus 2.0% for IUS. Costs increased with emissions. When clinically appropriate, substituting IUS for colonoscopy or MR enterography could reduce per‐procedure emissions by 78.0% and 96.0%, respectively. Conclusions Carbon emissions and cost rise together across IBD diagnostics; when clinically appropriate, IUS is the lowest‐carbon, lowest‐cost imaging modality. Patient‐level studies are needed to confirm modelled savings. Trial Registration ClinicalTrials.gov NCT07431983
