The aeronautic sector is a complex system where many stakeholders are involved. In this project is analyzed how are performed the Turnaround Processes (TAP) in El Prat Airport. These processes are the ones needed for attending the aircrafts during their scale, involving the use of fourteen different types of ground handling vehicles, classified as Light Duty Vehicles (LDV) or Heavy Duty Vehicles (HDV). As well, a characterization of the Land and Takeoff cycles (LTO cycles) performed in El Prat Airport is carried. The main objectives of this project are the quantification of the emissions generated by the ground handling vehicles and the aircrafts during 2017, and their associated environmental impact using the Simapro software. Then an alternative scenario is purposed, where the 19% of the ground handling vehicles are substituted by electric vehicles. A sustainability analysis using MIVES tool is carried, comparing the environmental, social and economic requirements between the actual scenario and the purposed one. The aircrafts are the main contributors in terms of emissions and environmental impact in comparison with the ground handling vehicles, accumulating a 97% of the total emissions and impacts. The contribution of the aircrafts is higher when the Green House Gases emissions and their associated impacts are analyzed. Oppositely, it decreases when the total polluting gases are compared. The main aircrafts performing LTO cycles in El Prat airport are the A320, the B738 and the A321. In proportion, this three aircrafts types represents a 70% of the total LTO cycles performed in El Prat airport, thus, they are the main contributors in terms of emissions and environmental impact. There aren’t notorious differences between the emission factors of each aircraft, so the total contribution is related to the percentage of aircraft types performing LTO cycles at the airport. Regarding at the ground handling vehicles, the main emission sources are the follow me vehicles, the refueling trucks, the cargo tapes, the pushback vehicle and the catering vehicle. The HeavyDuty Vehicles accumulates a 60% of the ground handling emissions and environmental impact, but the contribution per vehicle depends on the analyzed environmental impact category: for the impacts related with the CO2 emissions, the follow me vehicle (a LDV), is the most contributing vehicle, but for the other impact categories, the HDV are the most contributors. The sustainability analysis results indicate that, just when the economic requirement is set as the most weighted requirement (between the social and the environmental ones), the actual scenario has an increased sustainability index in comparison with the purposed scenario. For any other weighting configuration, the sustainability index is higher for the purposed scenario, meaning that the substitution of diesel vehicles by electric ones is a viable consideration.
