Abstract

BACKGROUNDMore than 10 million individuals develop active TB each year. The diagnosis and treatment of TB create greenhouse gas emissions, contributing to climate change. This study estimates the carbon footprint (CF) of successfully treating one person with drug-susceptible pulmonary TB (DS-PTB) in India.METHODSWe defined the cascade of care for DS-PTB using national guidelines, interviews, and direct observation. We estimated the inputs for TB diagnosis and treatment in United States dollars, kilowatts per hour, and kilometres travelled; we converted them into carbon dioxide emissions equivalents (CO₂e) using an appropriate calculator.RESULTSThe CF of diagnosing and treating one person with DS-PTB in India is 103.8 kg CO₂e: 31.9% attributable to diagnosis and 68.1% to treatment. Emissions came primarily from first-line drugs (21.2%), hospitalisations (17.4%), and laboratory processes.CONCLUSIONWe conservatively estimate that treating all persons with TB in India would produce at least 290,640 metric tonnes of CO₂e per year, approximately the same emissions as 63,182 passenger cars in the United States. It is evident that one of India's leading public health challenges also contributes meaningfully to climate change..

清除空气：对药物敏感性肺结核治疗的碳影响进行微成本计算。

背景每年有 1000 多万人罹患活动性肺结核。结核病的诊断和治疗会产生温室气体排放，导致气候变化。本研究估算了在印度成功治疗一名药物敏感性肺结核（DS-PTB）患者的碳足迹（CF）。方法我们通过国家指南、访谈和直接观察，确定了 DS-PTB 的治疗流程。我们估算了结核病诊断和治疗的投入，单位为美元、千瓦/小时和行驶公里数；我们使用适当的计算器将其转换为二氧化碳排放当量（CO₂e）。结果在印度，诊断和治疗一名 DS-PTB 患者的二氧化碳排放量为 103.8 千克 CO₂e：31.9%来自诊断，68.1%来自治疗。我们保守地估计，在印度治疗所有肺结核患者每年将产生至少 290,640 公吨二氧化碳当量，大约相当于美国 63,182 辆乘用车的排放量。很明显，印度面临的主要公共卫生挑战之一也对气候变化产生了重大影响。
