Abstract (EN): This study aims to compare soy methyl esters (biodiesel) and liquefied petroleum gas (LPG) as automotive fuels in Portugal using LCA. The potential environmental impacts (PEI) associated with their life cycles are compared for twelve impact categories. As a general conclusion biodiesel has a lower total PEI than LPG. Nonetheless biodiesel shows higher values of some individual impact categories such as acidification, photo-oxidant formation, terrestrial eutrophication, and land use. This study results can be used to support decision making and recommendations about the environmentally preferable fuel to be used in Portugal, which should be complemented with economic and societal considerations.
