UNASSIGNED: This study proposes a methodology for calculating the carbon footprint of EBRT and applies it to a single center. Mitigation strategies are derived from the carbon inventory, and their potential reductions are quantified whenever possible.
UNASSIGNED: The average emission per treatment and fraction delivered was 489 kg CO₂eq and 27 kg CO₂eq, respectively. Patient transportation (43 %) and the construction and maintenance of linear accelerators (LINACs) and scanners (17 %) represented the most significant components. Electricity, the only energy source used, accounted for only 2 % of emissions.Derived mitigation strategies include a data deletion policy (reducing emissions in 30 years by 12.5 %), geographical appropriateness (-12.2 %), transportation mode appropriateness (-9.3 %), hypofractionation (-5.9 %), decrease in manufacturers\' carbon footprint (-5.2 %), and an increase in machine durability (-3.5 %).
UNASSIGNED: Our findings indicate that a significant reduction in the carbon footprint of a radiotherapy unit can be achieved without compromising the quality of care.This study provides a methodology and a starting point for comparison and proposes and quantifies mitigation strategies, paving the way for others to follow.
■这项研究提出了一种计算EBRT碳足迹的方法,并将其应用于单个中心。缓解策略来自碳清单,并尽可能量化其潜在的减少量。
■每次处理和部分输送的平均排放量为489千克二氧化碳当量和27千克二氧化碳当量,分别。患者运输(43%)以及直线加速器(LINAC)和扫描仪(17%)的构造和维护是最重要的组成部分。电,唯一使用的能源,仅占排放量的2%。衍生的缓解策略包括数据删除策略(在30年内减少12.5%的排放量),地理适当性(-12.2%),交通方式适当性(-9.3%),低分馏(-5.9%),制造商碳足迹下降(-5.2%),和机器耐久性的增加(-3.5%)。
■我们的发现表明,可以在不影响护理质量的情况下实现放射治疗单元碳足迹的显着减少。本研究提供了比较的方法和起点,并提出和量化了缓解策略,为其他人铺路。
