  "abstract": "Background and Importance The transport of rural cancer patients to intravenous (IV) chemotherapy administration used to generate periodic greenhouse gas emissions. Rough mountain roads across a large territory forced patients to spend at least 2 hours daily travelling, indirectly contributing to depopulation. The Public Regional Health Area (PRHA) used to invest thousands of euros in driving them to corresponding oncohaematological Urban Hospitals. In March 2025, a new cleanroom was inaugurated in the Rural Hospital, improving access to care and service proximity.Aim and Objectives Analyse carbon footprint, travel time and cost impact during 2021-2024, evaluate savings between March-September 2025 and estimate potential savings during 2026-2030 at rural Hospital.Material and Methods Carbon footprint calculation based on carbon dioxide (CO 2) driving emissions between 13 urban Hospitals and the rural one. The institutions recruited 8% gasoline (134g CO2/km) and 92% gasoil taxis (174g CO2/km) for patients’ transportation, costing 0.73€/km. Wasted time estimation is provided by the shortest standard inter-hospital routes, excluding harsh weather conditions delays, unexpected traffic events and waiting time in medical centres. The retrospective study based on PRHA data between 2021-2024, including patients ≥18 years from 281 villages who received cancer treatment in metropolitan hospitals. Metastatic melanoma, osteosarcoma, germinal, neuroendocrine and neurologic tumour diagnoses excluded. Projections for 2026-2030 derived from soft saturation logistic model.Results Between 2021-24, 191 candidates’ journeys were analysed: total of 80,093 kg CO 2 emitted, 6,381 travelled hours and transport cost 565,175€. Between March-September 2025, eight referred patients benefited from 105 IV chemotherapy administrations in the Rural Hospital, saving 1,787 kg CO2, 142 hours of travel and 7,636€. Extrapolation from 2026–2030, estimates potential savings of 190,784kg CO2, 15,110 h and at least 815,410€, based on the estimated kilometres.Conclusion and Relevance Local preparation and administration of IV chemotherapy at the Rural Hospital significantly reduce CO 2 emissions, patient travel time and cost pertinent. With increasing life expectancy and advances in early cancer detection, more patients are likely to benefit, suggesting current estimations are conservative with respect to the potential impact. More studies are needed to evaluate patients’ satisfaction.References and/or Acknowledgements 1.
