The Effect of Climate Condition on the CO₂ Emissions of Maintenance Activities: a Case Study From Railway

Climate conditions significantly impact the working conditions for inspection and maintenance of railway assets, which may lead to higher carbon dioxide (CO2) emissions.This study investigates the impact of seasonal climate variations on CO2 emissions associated with inspection and maintenance activities for railway infrastructure.A case study from a railway system in northern Sweden is analysed to demonstrate how climate condition affects CO2 emissions during inspection and maintenance, across different seasons.To achieve this, CO2 emissions are estimated under varying climate conditions by integrating multiple datasets and conducting interviews with maintenance experts.The findings reveal that seasonal variations play a critical role in CO2 emissions, with significantly higher emissions observed in cold weather due to increased fuel consumption.These insights underline the importance of accounting for climate-related factors in maintenance planning to mitigate environmental impact.The result of analysis can be used for maintenance planning strategies to reduce CO2 emissions associated with railway asse.
