Environmental Performance of Passenger Cars in the KSA: Comparison of Different Technologies via a Life Cycle Assessment Approach
Analyzing the environmental performance of alternative vehicle technologies in the current energy landscape of the Kingdom of Saudi Arabia (KSA) is very important given their expected role in future transportation systems. This study presents a comprehensive life cycle assessment (LCA) of sedans and sport utility vehicles (SUVs) powered by different propulsion systems to analyze their environmental performance in the KSA context. The LCA examines multiple impact categories, with a particular focus on global warming potential (GWP). The results reveal that hybrid electric vehicles (HEVs), fuel cell electric vehicles (FCEVs), and plug-in hybrid electric vehicles (PHEVs) consistently demonstrate the lowest GWP across both sedan and SUV vehicle classes, achieving reductions of approximately 30%, 28%, and 22%, respectively, compared with the baseline gasoline-powered internal combustion engine vehicles (ICEVs). Battery electric vehicles (BEVs) also exhibit lower GWP (approximately 16%) than do conventional ICEVs but to a lesser extent than do other advanced powertrains. The energy supply chain plays a crucial role for BEVs, including FCEVs and PHEVs, underscoring the importance of decarbonizing electricity and hydrogen (H2) production to realize the full environmental advantages of these technologies in the KSA. In terms of deployment feasibility, PHEVs and HEVs have a distinct advantage over FCEVs, as they can leverage the existing electricity grid and fueling infrastructure, making them a more practical and readily available solution for reducing near-term emissions in the KSA transportation sector. Policymakers and industry stakeholders are encouraged to develop targeted incentives, regulations, and support mechanisms to accelerate the market penetration of these technologies while also considering strategies to address their multifaceted environmental implications.
