Sustainable development is a kind of development where the pace of technical development, the satiation of increasing supply and the raw materials and resources of the Earth are poised so that the rate of living and the opportunities of the future generations should not decline. For this reason, transportation systems must be developed and the effectiveness of transportation service must be increased while environmental pollution must be decreased or prevented. Vehicles are burning fuels inefficiently. There are two options of decreasing environmental impacts – one is to reduce fuel consumption while another is to do it in a more acceptable way increasing efficiency. There is justifiable demand put forward by the society to moderate environmental impacts caused by road transportation. This article deals with modelling the energetic utilisation of exhaust gas.

“Act so that the effects of your action are compatible with the permanence of genuine human life on Earth.” How can we understand Jonas’ “maxim”? Is it too anthropocentric to be of any interest for an environmental ethic? Is is too limited to survival to have a moral signification in a truly human ethic? One can argue first that it is not so much anti-Kantian than that it challenges the current prevailing “presentism” and obliges us to take into consideration not only future generations, but also the context in which one anticipates these future generations to be living. Therefore, we can distinguish two different interpretations of Jonas’ maxim: in a first stage, that of sustainable development, it was understood as taking into consideration not only the needs but also the rights of future generations; in a second stage, that of an Anthropocene and ecological transition, it means that making sense of humanity implies connecting human beings to the Earth and other living beings far from opposing them.

The aim of this article is to prove the connection between CO2 emission and climate change, and to estimate the CO2 emission of the transport sector in Hungary. We have to clarify the emission of the transport sector in order to get information on externalities, which is a further step toward a sustainable society. The sustainable development is a development, where the pace of technical development, the satiation of increasing supply and the raw materials and resources of Earth are poised so that the rate of living and opportunities of the next generations need not be worse. One of the most emphasized goals of the transport policy of the European Union is sustainable mobility. For this reason transportation systems must be developed and standardized, the effectiveness of transportation services must be increased, while the environmental pollution must be decreased or prevented. Decoupling motorization from environmental pollution is the task for engineers. Decoupling the increase of economical activity from mobility is the task for economists.

Vehicles are burning fuels inefficiently. Nowadays, there is a strong correlation between CO2 emission and climate change. The article estimates a theoretical environmental impact of biofuel mixtures on the transport sector. A high ratio of road transportation in CO2 emission caused by humanity made necessary to research the estimation of the environmental impact of biofuel mixtures. We have to clarify the emission of the transport sector in order to get information about the role of the impact that is a further step to a sustainable society. Sustainable development is a kind of development where the pace of technical development, the satiation of increasing supply and the raw materials and resources of the Earth are poised so that the rate of living and the opportunities of the future generations should not decline.

For this reason, transportation systems must be developed and standardized and the effectiveness of transportation service must be increased while environmental pollution must be decreased or prevented. There is a justifiable demand put forward by the society to moderate the environmental impacts caused by road transportation. This article deals with modelling the environmental impact of ethanol‐gasoline mixtures and diesel oil‐ethanol‐biodiesel mixtures.

The United Nations Sustainable Development Goals are grouped under three main titles; economic development, environmental sustainability, and improvement of social well-being. Environmental sustainability is one of the most important components of sustainable development goals because it is obvious that without a sustainable environment, economic and social development goals will be abandoned. While the unplanned use of the environment and natural resources threatens environmental sustainability, it can be said that one of the most important actors in this process is sports. Mass production and consumption, facility establishment, and increase in organizations in sports accelerate environmental and natural destruction. The sustainability of sports is directly proportional to environmental sustainability. Therefore, reduction of the sports-induced negative environmental impacts will make great contributions to environmental sustainability. In this way, it will be possible to transfer both the natural environment and sports to future generations. This study was limited to environmental sustainability, which is one of the three main titles set for sustainable development goals and the effects of sports on environmental sustainability were evaluated in the light of available literature. Again, regarding the existing literature, suggestions were developed to reduce the negative environmental impacts of sports.

<p>Due to the increasing rate of human’s economic activity and rapid population growth, twenty first century has seen an unprecedented environmental change. These changes have an unprecedented impact on climate, life-sustaining systems on the earth. Future generations are exposed to great harm by the way in which humans exploit environmental resources of the earth. There is a call among environmental ethicists to review human ethical relationship with the environment as to attain sustainable development for the now and the future generations. Hence, the essence of this paper is to discuss the anthropoholistic environmental ethics, sustainable development and the future Generations. This paper argues that humans need to strive for a new and more respectful relationship with the natural environment in other to attain sustainable development. Also, human obligations towards sustainable development for the future must find a firm basis in social ethics: those obligations have to do with our conception of a just society.</p>

Cross-laminated timber (CLT) used in the U.S. is mainly imported from abroad. In the existing literature, however, there are data on domestic transportation, but little understanding exists about the environmental impacts from the CLT import. Most studies use travel distances to the site based on domestic supply origins. The new Adohi Hall building at the University of Arkansas campus, Fayetteville, AR, presents the opportunity to address the multimodal transportation with overseas origin, and to use real data gathered from transporters and manufacturers. The comparison targets the environmental impacts of CLT from an overseas transportation route (Austria-Fayetteville, AR) to two other local transportation lines. The global warming potential (GWP) impact, from various transportation systems, constitutes the assessment metric. The findings demonstrate that transportation by water results in the least greenhouse gas (GHG) emission compared with freight transportation by rail and road. Transportation by rail is the second most efficient, and by road the least environmentally efficient. On the other hand, the comparison of the life cycle assessment (LCA) tools, SimaPro (Ecoinvent database) and Tally (GaBi database), used in this research, indicate a remarkable difference in GWP characterization impact factors per tonne.km (tkm), primarily due to the different database used by each software.

Para sobreviverem à crise global as empresas necessitam adotar medidas de contenção dos gastos, sendo que as operações logísticas se apresentam como fundamental nesse processo, diante dos custos elevados com transporte rodoviário. Acrescenta-se que o principal fator para os altos custos são os preços dos combustíveis, o que remete a mudanças nos processos de transporte com o intuito de diminuir o consumo de combustível utilizado no transporte. O objetivo desta pesquisa é propor mudança no processo de transporte da cana-de-açúcar para redução do consumo de combustível. Para atingir os resultados, foram utilizados como processos metodológicos a pesquisa bibliográfica com consulta em livros, artigos científicos e dissertações, com o devido rigor científico, seguida de estudo de caso com abordagem quantitativa. Dessa forma, foi realizada a fundamentação teórica por meio da pesquisa bibliográfica para embasar o trabalho e, em seguida, desenvolvido o estudo de caso mediante pesquisa documental primária, para realizar um comparativo entre as quantidades de consumo de combustíveis utilizados no método convencional e os valores projetados em uma mudança no método de transporte. Contudo, após a realização do estudo, foi possível observar que, mesmo diante de uma economia estimada em 10% no consumo de combustíveis, haverá aumento nos custos em proporção inversa, no que tange à manutenção de equipamentos, o que revela uma projeção de economia estimada em 9% dos custos totais.   PROCESS ANALYSIS AT A SUGARCANE COMPANY FROM TRIÂNGULO MINEIRO: CASE STUDY TO REDUCE FUEL CONSUMPTION IN TRANSPORTATION SERVICE   ABSTRACT In order to survive the global crisis companies need to adopt some measures to lower costs since logistic operations are essential for this process in the face of high costs with road transportation. In addition, the main reason for the high cost is the heavy price of the fuel resulting in changes in the transportation process in order to increase its fuel consumption. This paper aims to suggest changes in the sugarcane transportation process to reduce fuel consumption.  Conducive to obtain such results, it was used as a methodology for the bibliographic review by using books, scientific articles, and dissertation, with due scientific rigor, followed by a study case with a quantitative approach. Therefore, carrying a theoretical ground out through bibliographic research to support the paper, and, followed by a case study through primary documental research, to compare fuel consumption quantity used for conventional methods and the projected values for a change in transportation. However, after this study had been carried out, it was possible to note that, even in the face of a reduction estimated at 10% for fuel consumption, there will be an increase in costs in inverse proportion, regarding equipment maintenance, which reveals a projection for an estimated reduction in 9% of the total costs.   Keywords: Logistic.

The essence and urgency of government expenditure for regional development is very crucial in realizing sustainable development, meaning that government spending must meet current needs without compromising the fulfillment of the needs of future generations. The higher the state revenue, the higher the state expenditure for regional development. Thus, an increase in understanding of government expenditure for regional development in a sustainable manner must be carried out with the principle of prudence in this country.
