SUMMARY:

This dissertation presents an environmental and cost assessment of the electrification of the Brazilian Air Force’s (FAB) fleet of light-duty vehicles. The scope of the study included Internal Combustion Engine Vehicles (ICEV), Hybrid Electric Vehicles (HEV), and Battery Electric Vehicles (BEV), using ethanol or gasoline. In this context, the Life Cycle Assessment (LCA) methodology was applied, according to the NBR ISO 14040 and NBR ISO 14044 standards, to quantify CO2eq emissions during the production and use phases of the vehicles. Additionally, an economic analysis was carried out, considering the acquisition, maintenance, and operational costs of the vehicles. An inventory model for emissions calculations was created for vehicles in use, based on the year and model data of each one, as well as for future acquisitions, depending on the chosen technology. The findings suggests that ethanol plays a key role in reducing emissions, and for sedans, combined with hybrid technology, the most sustainable results are achieved. For compacts, due to the lack of hybrid models, ethanol-powered ICEV are the most sustainable in most regions of the country, except in the Northeast, where, due to its clean energy matrix, BEV achieved better environmental performance over a 15-year period. The acquisition costs of electric vehicle (EV) remain very high compared to ICEV, suggesting that specific incentive policies for public institutions are necessary to make their adoption feasible. The study aims to support strategic decisions regarding fleet renewal through an integrated approach that considers both environmental and financial benefits, contributing to the sustainability and operational efficiency of the Air Force.
