“…A literature review related to the future of transportation in sustainable energy systems is presented in [28] which also traces the importance of electric modes of transportation to promote the largest benefits in the transport transition. A multiobjective optimization model was developed by [29] with a particular focus on finding the most efficient bus fleet combination for a city located in the South region of Brazil. The authors pointed out the electrical bus as the best choice for reducing greenhouse gas emissions among the other analyzed alternatives.…”

Shaping a secure and sustainable energy future may require a set of transformations in the global energy sector. Although several studies have recognized the importance of Electric Vehicles (EVs) for power systems, no large-scale studies have been performed to assess the impact of this technology in energy systems combining a diverse set of renewable energies for electricity production and biofuels in the transportation sector such as the case of Brazil. This research makes several noteworthy contributions to the current literature, including not only the evaluation of the main impacts of EVs’ penetration in a renewable electricity system but also a Life-Cycle Assessment (LCA) that estimates the overall level of CO2 emissions resulted from the EVs integration. Findings of this study indicated a clear positive effect of increasing the share of EVs on reducing the overall level of CO2 emissions. This is, however, highly dependent on the share of Renewable Energy Sources (RES) in the power system and the use of biofuels in the transport sector but also on the credits resulting from the battery recycling materials credit and battery reuse credit. Our conclusions underline the importance of such studies in providing support for the governmental discussions regarding potential synergies in the use of bioresources between transport and electricity sectors.

“…Moreover, considering the US practice, which states that bus must remain operational for at least twelve years to qualify for federal funds [32], shows just how much the operability depends on the maintaining quality. Therefore, under the pressure of budget constraints, the agencies road design [69], way of ticketing [70,71], platform issues [10,51], headway regularity [72], emission [73], and special events [74]. All of the factors affect mobility managers' optimisation and scheduling whether they are Bus Rapid Transit (BRT) [75,76] roadways, trolley fixed roadways [77], or conventional infrastructures.…”

The research on Bus Fleet Management (BFM) has undergone significant changes. It is unclear whether these changes are accepted as technological change or as a paradigm shift. Perhaps unintentionally, BFM is still perceived as routing and scheduling by some, and by others as maintenance and replacement strategy. Therefore, the authors conducted a Systematic Literature Review (SLR) to overview the existing concepts and school of thoughts about how stakeholders perceive the BFM. The SLR post-study exposed that BFM should be acknowledged as a multi-realm system rather than a uniform dimension of fulfilling timely service. Nonetheless, the work encapsulates BFM evolution which shows the need for the multi-realm research abstracted as "Bus Fleet Mobility Management" and "Bus Fleet Asset Management". The difficulties of transport agencies and their ability to switch from conventional to Zero-Emission Buses (ZEBs) illustrates why we propose such an agenda, by which the research is validated through needs both in academia and in practice.

“…Together with environmental, various papers dealt with the economic aspects of investment in urban transport decarbonisation. For instance, [16] presented a multi-objective optimization model to find efficient bus fleet combinations taking into account GHG emissions, conventional air pollutant emissions, and costs. Heating and the thermal management of the urban electric buses were the subjects of research in [17].…”

The article deals with green investment focused on urban public transport. This work presents a holistic approach to evaluating investments in electric and CNG buses, i.e., the economic efficiency assessment, including the risk aspect. The investment project is assessed in terms of the source of funding and risk factors affecting the profitability of the project. A non-repayable subsidy from the European Social Fund in the amount of 0%, 25%, 50% and 90% of investment costs is considered. Economic efficiency is assessed in terms of profitability through the financial criterion Net Present Value (NPV) and risk using mean NPV and standard deviation. The result of the evaluation of the variants of the investment project is that the investment project without the support of non-repayable resources is loss-making. With a low level of financial support, it is more economical to procure CNG buses. With a higher level of financial support, investments in electric buses are more profitable, due to lower operating costs.
