Conclusion: These initial findings highlight that the biggest contributor to RT carbon footprint was patient travel. This result suggests how the adoption of hypo-fractionated treatments may represent a possible way to reduce RT carbon footprint. This study represents the initial step of a bigger and ambitious IEO project called Green Radiotherapy , aiming at developing a software to estimate CO 2 emissions generated per patient at the end of RT. The software will be based on a predictive model developed on prospective data that will be applied retrospectively on data of
