PurposeThe goal of this study is to identify which processes contribute most to fuel CO₂e emissions, energy use, and employment generation when driving a typical Brazilian flex fuel vehicle (FFV) model with bagasse-derived ethanol. A hybrid life cycle assessment (LCA) is used to report the associated impacts and a structural path analysis (SPA) is utilized to identify, quantify, and rank the highest carbon emissions, energy use, and employment generation input paths in the supply chain of bagasse-derived ethanol. Additionally, this study explores the integrated hybrid LCA approach as a tool to explain the economic impacts of bagasse-derived ethanol.
