“…Criteria for the economic efficiency of vehicles mainly concern the acquisition costs minus any subsidies and the residual value of a vehicle to be achieved, as well as running costs such as energy consumption or maintenance and repair costs. Numerous sources are available for a comprehensive consideration of economic efficiency criteria (Bertram & Bongard, 2014;Hacker et al, 2015;Wietschel et al, 2019).…”

Research purpose. Against the backdrop of climate change, pressure is growing in the transport sector to reduce CO2 emissions. Numerous companies are therefore setting specific targets to curb the CO2 emissions of their own vehicle fleets. As a rule, this requires the replacement of combustion vehicles by vehicles with alternative drives. In addition to the selection of suitable technologies, economic aspects play a prominent role in this transformation process. Based on a practical case study, potential implementation strategies for achieving a specific CO2 target are to be examined for a parcel service provider. The focus here is on a fleet of diesel combustion vehicles from the small van class with a permissible total weight of fewer than 3.5 tons, which are to be replaced by vehicles with electric drive (BEV) in order to achieve a specific CO2-savings target. The research objective can be easily extended if one considers, on the one hand, that climate protection cannot be limited to individual countries but has to take place on a global level and, on the other hand, that sustainable strategic planning of vehicle fleets also concerns other vehicle segments, such as company cars for individual transport or trucks with higher permissible gross weights. Design / Methodology / Approach. In the first step, framework conditions and criteria are defined that are needed for an evaluation of the implementation strategies. In the second step, a practical case study is constructed. In the third step, different scenarios and strategies for the conversion of the vehicle fleet are designed in order to achieve the set CO2-emission targets. In the last step, the economic and ecological effects of the different strategies and scenarios are measured and analysed with the help of the calculation tool "DIPO-tool", which was developed at the Ludwigshafen University of Business and Society LUBS for research and teaching purposes. To evaluate sustainability, in addition to the established metrics for Tank-to-Wheel (TtW) and Well-to-Wheel (WtW), a holistic life cycle approach is implemented that takes into account emissions during vehicle production. Findings. Against the backdrop of expected further technological development and numerous parameters with a considerable leverage effect on economic and ecological evaluation criteria, it seems advisable from the point of view of sustainability to use alternative drives as soon as possible. From the point of view of economic efficiency, a more differentiated picture emerges depending on the framework conditions, e.g., subsidies. Originality / Value / Practical implications. The originality of the approach lies in the application of a practical case study and the attempt to reduce the complexity of the decision problem by using an Excel-based calculation tool. The value of the study lies in the realisation that, due to the complexity, a simple optimisation approach does not seem viable but rather the evaluation and analysis of different scenarios. The practical impact can be described in the sense that the used DIPO-tool can provide effective support for sustainable implementation strategies for vehicle fleets.

“…The recuperation efficiency is determined based on the electric drivetrain efficiency, which is responsible for recuperating the braking energy. The electric drive shares for PHEVs and REEVs are taken to be a function of their yearly driven distance [51]. The average occupancy for all LDVs is assumed to be 1.3 passengers per vehicle, which is the average value for Germany [52].…”

The importance of a flexible and comprehensive vehicle fuel consumption model cannot be understated for understanding the implications of the modal changes currently occurring in the transportation sector. In this study, a model is developed to determine the tank-to-wheel energy demand for passenger and freight transportation within Germany for different modes of transport. These modes include light-duty vehicles (LDVs), heavy-duty vehicles (HDVs), airplanes, trains, ships, and unmanned aviation. The model further estimates future development through 2050. Utilizing standard driving cycles, backward-looking longitudinal vehicle models are employed to determine the energy demand for all on-road vehicle modes. For non-road vehicle modes, energy demand from the literature is drawn upon to develop the model. It is found that various vehicle parameters exert different effects on vehicle energy demand, depending on the driving scenario. Public transportation offers the most energy-efficient means of travel in the forms of battery electric buses (33.9 MJ/100 pkm), battery electric coaches (21.3 MJ/100 pkm), fuel cell electric coaches (32.9 MJ/100 pkm), trams (43.3 MJ/100 pkm), and long-distance electric trains (31.8 MJ/100 pkm). International shipping (9.9 MJ/100 tkm) is the most energy-efficient means of freight transport. The electrification of drivetrains and the implementation of regenerative braking show large potential for fuel consumption reduction, especially in urban areas. Occupancy and loading rates for vehicles play a critical role in determining the energy demand per passenger-kilometer for passenger modes, and tonne-kilometer for freight modes.
