Transportation is a complex, technology-intensive socio-technical system, which needs to be tackled in an integrated manner. Also, transportation as a sector is a significant component of any national economy, and has far-reaching implications both with regard to socio-economic and environmental well-being of the society and within the context of sustainability science. For this reason, sustainable transportation is not only an important field of research within the academia but also an indispensable constituent of a sustainable economy. Therefore, investigating the path to sustainable transportation requires a holistic approach, encompassing the three dimensions of sustainability, i.e. environment, society, and economy. There are several proposals as to how to transition to a more sustainable transportation sector globally, and one of the most promising options is the electrification of vehicles. Hence, it is crucial to look at the electrification of transportation from different angles, and scrutinize different aspects to this matter. This project developed several integrated sustainability assessment models that include the socio-economic as well as the environmental implications of an electrified transportation sector. These developed models covered a wide variety of means and aspects of an electrified transportation such as passenger vehicles, electric vehicle (EVs) market penetration, electric buses and long-haul trucks, vehicle to grid (V2G) technology that included delivery trucks, and the potential use of electric vehicles as a source of energy both for the grid and homes, i.e. vehicle to home technology (V2H). In the modeling, consideration was applied to stochastic costs, electricity mix sustainability, and life cycle impacts such as environmental, e.g. life cycle greenhouse gas emissions, social, e.g. life cycle health costs, and economic, e.g. life cycle costs. In-depth comparison between electric vehicles and other alternative fuel vehicles (AFVs) (incl. hybrid-electric, plug-in hybrid-electric, liquefied-natural gas, compressed-natural gas, biodiesel-powered vehicles) was carried out to investigate the major advantages and/or disadvantages of electrifying different means and types of transportation, e.g. passenger vehicles, transit buses, and long-haul trucks. |
