“…And the total or gradual elimination of diesel and gasoline cars. Green cars include, first of all, hybrid, electric and hydrogen-powered cars, as well as the increasingly popular V2G (vehicle to grid) cars [28,29,30,31,32,33]. Replacing the fleet with the so-called green fleet obviously requires a lot of commitment on the part of the entrepreneur in environmental strategies.…”

Supply chain management is one of the most important elements of sustainable development. And due to the fact that the world market is driven by supply and demand, and the determinant of access to products is regional and international logistics, this paper focuses on the possibilities of implementing a green transport strategy in the context of sustainable development in logistic enterprises. This paper presents the results of the SWOT analysis pointing out the strengths, weaknesses, opportunities, threats of green vehicles market for the transport enterprises. It was noticed that the situation on the green vehicles market for the transport enterprises is characterized by the advantage of strengths and these strengths should be used to maximize the use of green vehicles. It emphasized that subsidies for green vehicles would allow to invest in a modern fleet, new solutions (e.g. own charging stations) can have an impact on the greater energy efficiency (self-sufficiency), increase of social awareness would force enterprises to take appropriate actions in the field of environmental protection and development of public transport based on green vehicles.

This study aims to clarify the flow characteristics and wake structure of convertible vehicles. Numerical simulations are performed to obtain a preliminary visualization, and the potential vortical motion characteristics are investigated by examining the Q-criterion across multiple cross-sections. Comparisons between numerical and experimental results validate the reasonableness of our numerical model. The predominant wake topology of a two-seat convertible is obtained in terms of the location, shape, and spin direction of the vortices. We observe a "nook" vortex that is triggered by the flow acceleration induced by the pressure gradient near the windshield step, provoking undesirable aeroacoustic noise and degrading the cabin comfort. Complicated A-pillar vortex dynamics are revealed, with small vortices that are shed into the cabin and impinge the seats, eventually forming a long tail structure above the back of the vehicle. Moreover, periodic fluctuations of the windshield vortex are induced by the Kelvin-Helmholtz instability, significant impacting the streamwise wake. Ultimately, the combined motion characteristics of the A-pillar and windshield vortices exert undesirable effects on the aeroacoustic noise and drag, suggesting fundamental mechanisms for achieving optimal energy-saving and acoustic convertibles in the future. Based on the wake topology and the vortical generating mechanism, approaches are proposed to reduce the drag and aeroacoustic noise by impeding the flow over the door into the cabin and modifying the shape of windshield step, and lengthening the windshield in stream direction.

Malaysia has initiated a roadmap aligned with the United Nations’ 17 Sustainable Development Goals (SDGs) to integrate them into its national development strategy. Chaired by the Prime Minister, the National SDG Council has established a participatory governance structure to foster collaboration among government agencies, civil society, and the private sector, promoting understanding of the SDGs’ interconnectedness. National symposiums and focus group sessions have been conducted to raise awareness and gather stakeholder input in formulating SDG-related policies and programs. Collaboration with NGOs, civil society, and the private sector has been prioritized, with initiatives integrated into the 11th Malaysian Plan to incorporate sustainable development into the national strategy. The creation of a national SDG Roadmap will offer a systematic approach to realizing the UN’s 2030 Agenda for SDGs. Chemistry serves as a crucial element in advancing SDGs by addressing pressing challenges and exploring new avenues for sustainable development. This article examines Malaysia’s sustainable development journey through a chemical lens, addressing 12 of the 17 SDGs. Malaysia aims to play a pivotal role in achieving these goals, addressing environmental, social, and economic challenges by leveraging scientific knowledge and innovation in chemistry. The recommendations underscore Malaysia’s potential to become a more resilient and sustainable nation, contributing significantly to global sustainability efforts.
