Personal light electric vehicles (PLEVs) are a phenomenon that can currently be observed in cities, intended to be an ecological form of transport. The authors of the paper make an attempt to determine electricity consumption by PLEVs in the context of managing a large city in accordance with the concept of sustainable development. The article is of a cognitive nature. Research questions posed against the background of the goal formulated are as follows: how strong will the demand for PLEVs be (in the example of e-motor scooters, taking into consideration the number of vehicles) and for the electricity consumed by PLEVs. The method used is a simulation model. The conducted analyses demonstrate that a dynamic growth of PLEVs will result in an increased energy demand, which must be taken into account by the cities, developing according to the sustainable development conception.

Nearly two-thirds of the emissions that cause smog come from road transport. In April 2019, the European Parliament adopted new regulations on public procurement to encourage investment in clean buses—electric, hydrogen, or gas. Directive 2009/33/EC is to apply from the second half of 2021. The aim of this article is to make an attempt to simulate the number of zero-emission buses (ZEB) in European Union (EU) member countries in two time horizons: 2025 and 2030, and to forecast the number of clean vehicles in the precise time horizons, including before and after 2050. Research questions are as follows: (1) what will be the number of ZEBs in individual EU countries over the next few years; (2) which of the EU countries will reach by 2030 the level of 95% share of ZEBs in all buses, which are a fleet of public transport buses; and (3) in which year will which EU countries reach the level of 95% share of zero-emission buses. The method used is a Bass model. The conducted analyses demonstrate that, by 2050, only four of the EU members will be able to reach 95% level of share of clean buses in the city bus transport fleets. It is likely that other countries may not achieve this even by 2050.

The main aim of the article is to present an analysis of the current challenges and threats to the Transport-Forwarding-Logistics (TFL) sector in Poland based on internet surveys. The aim of the article is, therefore, to investigate whether the challenges and threats described by managers in a two-year perspective are related to sustainable development. This area primarily concerns external conditions. On the other hand, in the surveys that were the subjects of the analyses, a section related to sustainable development in economic, environmental, and social terms was identified, in which the focus was primarily on the internal activities of the company. The article has a practical dimension. The article analyzes comments from managers posted in an internet survey. They constitute a separate part of the questionnaire, which mainly concerns financial indicators and other factors that determine the company’s competitiveness. Half of the respondents are companies with foreign capital, and half-Polish companies. Based on the comments over a three-year period with over sixty managers from logistics companies in Poland, an analysis of the most important challenges that companies in the logistics industry have to face in the near future was presented. The survey is a part of a broader research project that has been conducted in the form of a quantitative survey among approximately sixty TFL companies for twenty-five years on an annual basis. The results of the survey are supplemented with an attempt to analyze the current situation in 2020 related to the impending economic recession as a result of the coronavirus disease 2019 (COVID-19) threat. The surveyed companies constitute a significant part of the TFL market in Poland. Thus, they are the benchmark for the entire industry. Therefore, an important value of the presented analysis is the up-to-date research, as well as the ability to relate the results and developed scenarios to the entire TFL sector.
