This thesis evaluates the impact of Micro Electric Vehicles (MEVs) on traffic emissions in Lisbon, specifically PMx, NOx, and CO2. The study uses software simulations to assess dif- ferent adoption rates of MEVs and analyzes the resulting data. The study adopts a pragmatic research philosophy, a deductive research type, and a quantitative research approach. The research strategy is a simulation that mirrors the real-world situation and replaces various percentages of fossil-fueled vehicles with MEVs. The results indicate that MEVs reduce traffic emissions, with reductions of 31.2%, 26.1%, and 18.9% for PMx, NOx, and CO2, respectively, at a 100% adoption rate. There is a strong correlation between MEV adoption rates and emissions reductions. The study also finds that time lost in traffic reduces alongside the emissions, with the most effective decrease found between 80% to 100% adoption rates. This study provides insights into the impact of MEVs on traffic emissions in an urban context and can inform pol- icymakers and stakeholders in making informed decisions regarding the adoption of MEVs to reduce emissions and improve traffic flow. The findings also suggest that MEVs can be part of the solution for sustainable mobility and could help address the issue of traffic emissions in Lisbon.
