Abstract:
Land-based transportation is a significant contributor to global greenhouse gas (GHG) emissions, with internal combustion engine vehicles (ICEVs) being the predominant mode of transport in this sector. As the world population grows and urbanisation accelerates, transport demand in metropolitan areas is projected to double by 2050, underscoring the critical need for sustainable transportation strategies, forecasting, and planning within an urban context. One challenge in this endeavour is the insufficient attention given to the distribution of vehicle grades within the overall car population during GHG impact assessment, despite the recognised importance of car grade by researchers and policymakers. In this study, we incorporate both engine type and vehicle grade distribution, derived from data on over 30,000 passenger cars registered with the Land Transport Authority (LTA) of Singapore between 2018 and 2022, into our Life Cycle Assessment (LCA) analysis. This approach ensures that our scenario-based studies on prediction and planning are more comprehensive than those that consider only the most popular models. Furthermore, while Singapore benefits from a relatively clean electricity supply, the current limitations in charging infrastructure negatively affect the GHG impact of Electric Vehicles (EVs). The insights from this research will inform the development of transportation policies for metropolises like Singapore, contributing to the advancement of a more sustainable transportation system.
