Climate Change Mitigation Through the Application of LCA Methodology on the Environmental Performance of Two Vehicles with Distinct Engines
The purpose of this paper is to compare the environmental performance of two internal combustion engine vehicles (ICEVs) with distinct engines, one with the conventional diesel engine and the other with an electric motor supply (hybrid diesel) and a diesel engine, and then to assess which one has less environmental impact. The Portuguese automobile park was chosen for this study. The purpose of the comparison of the two researched ICEVs is that they show many similarities in terms of features by having the same type of body and varying only in the power-train system. The life-cycle assessment (LCA) methodology is performed by utilizing one ICEV with 170 kW. In both ICEVs the direct environmental impact is evaluated through a quantitative analysis, and a comparison is made with the purpose to assess the ICEV with the best environmental performance. The inputs and outputs data were collected from different sources and treated by the software OpenLCA for each life-cycle stage. The results have shown that the hybrid ICEV has revealed to have generally a better environmental performance compared to the diesel ICEV.
