The interurban road transport is one of the largest sources of emissions within all the economical sectors of Spain and accounts for 30% of the total energy consumption and subsequent CO2emissions. Fuel consumption, mostly gasoline and diesel, has decreased by −0.7% between 2004 and 2009 despite the increase of vehicle fleet (14.7%) and related travelled performances (3.1%). The paper estimates the energy consumption and subsequent emissions of CO2 and pollutants, CO, NOx, PM and NMVOC, of the interurban road transport in Spain for the period 2004–2009 by the use of a conceptual procedure. This procedure makes an effort to allocate the fuel sales, liters of diesel and gasoline, across different categories of vehicles (ages and technologies) operating on the interurban Spanish roads. In order to elaborate the inventory of energy consumption and emissions, the procedure uses the emission factors from the Copert process-based model, optimized for the Spanish interurban driving conditions. According to the inventory, total CO2 emissions have decreased from 68.0 Mt of CO2in 2004 to 66.9 Mt (−1.6%). This trend is due to diesel road vehicles. The CO2 emissions of gasoline vehicles and the total emission of related pollutants followed a downward trend due to technological improvements of vehicles and decrease of gasoline consumption. The CO2 emissions of diesel vehicles and the total emission of related pollutants followed an upward trend due to the increase of diesel consumption despite technological improvements of vehicles. Better estimates of energy consumption and emissions are possible in the future by using specific emission factors for different vehicle categories based on telemetric systems.

The primary aim of this study was to assess and compare EU countries in terms of the use of renewable energy sources in road transport. The following research tasks were undertaken to realize this aim: (1) a review of the literature concerning the negative externalities in road transport, the concept of sustainable development, and legal regulations referring to the utilization of renewable energy sources; (2) presentation of changes in energy consumption (both traditional and renewable) in road transport in EU countries in the years 2008–2019; and (3) identification of leaders among the EU countries in terms of consumption of renewable energy sources in road transport. The aim and tasks were realized using the literature review and TOPSIS method as well as descriptive, tabular, and graphic methods. The analysis was conducted for 28 EU countries according to the status for 2019. The period of 2008–2019 was investigated. Sources of materials included literature on the subject and Eurostat data. Although renewable energy sources accounted for as little as 6% of total energy consumption in road transport in EU countries in 2019, this is a significant topical issue. It results from the direction in which changes need to be implemented in terms of energy generation in this area of human activity. It turned out that blended biodiesel and blended biogasoline were the most commonly used fuels originating from renewable sources. The application of the TOPSIS method resulted in the identification of five groups of EU member countries, which differed in terms of the degree of utilization of renewable energy sources in road transport. Luxemburg, Sweden, and Austria were leaders in this respect. In turn, Malta, Estonia, and Croatia were characterized by very low consumption of renewable energy. The greatest progress in the utilization of renewable energy sources in road transport was recorded in Sweden, Finland, and Bulgaria (changes in the relative closeness to the ideal solution from 0.15 to 0.27), while the greatest reduction in relation to other countries was observed in Austria, Germany, and Lithuania (changes from −0.35 to −0.22).

The Impact

This paper analyzes the mobility restrictions in the Palestinian territory on the population and the environment. The literature review shows a scientific concern for this issue, with an emphasis on describing mobility barriers and the severe conditions experienced by the population due to these barriers as well as the impact of mobility restrictions on employment opportunities. On the other hand, the literature review also shows a deficit in quantitative analysis of the effects of mobility restrictions on the environment, particularly on energy consumption and greenhouse gas emissions. This paper aims to fill this gap through a quantitative analysis by including data collection about mobility restrictions, using network analysis to determine the impact of these restrictions on inter-urban mobility, and analysis of the resulting energy consumption and CO2 emissions. The results show that mobility restrictions induce a general increase in energy consumption and CO2 emissions. The average value of this increase is about 358% for diesel vehicles and 275% for gasoline vehicles.

This paper investigates the impact of renewable energy sources (RESs), CO2 emissions, macroeconomics, and the political stability in a country on the Gross Domestic Product (GDP). The authors analyse the dynamics of RESs use, CO2 emissions, and GDP development and also test the following hypotheses: (1) The country’s economic growth is related to the energy consumption, in terms of both human resources and capital; (2) the share of the renewable energy consumption of the total energy consumption has a positive impact on the economic growth; and (3) the share of the renewable energy consumption of the total energy consumption is unrelated to the economic growth. To test the above hypotheses, the authors use the modified Cobb-Douglas production function, which also considers RES production volumes, CO2 emissions, and economic growth. The study employs data between 1995 to 2015 from the candidate and potential candidate countries for the EU membership. The data are drawn from the World Bank and Eurostat. The analyses entail panel unit root tests, Pedroni panel cointegration tests, fully modified OLS (FMOLS), dynamic OLS (DOLS) panel cointegration techniques, and the Vector Error Correction model (VECM). The findings confirm the relationship between RESs, CO2 emissions, and the GDP. For the EU countries, RESs as human resources and capital have an impact on the GDP. Moreover, the results reveal a correction retraction when the economic growth leads to an increase in renewable energy consumption. The investigation also finds that candidate and potential candidate countries for the EU membership should foster renewable energy development. The authors conclude that developing affordable and effective instruments and mechanisms to boost the RES implementation is necessary to decrease the anthropogenic impact on the environment (in particular, decreasing CO2 emissions) without any attendant reduction in the economic growth.

Since the life cycle of a building spans more than 50 years, studies of the environmental impacts in the construction industry have focused on reducing the energy consumption and greenhouse gas emissions during the operation and maintenance phase. The products of the construction industry are assembled using various building materials manufactured outside of the construction site. Consequently, it is essential that the manufactured building materials be transported to the construction site using various types of transportation methods. However, there is a lack of studies that assess the pollutant emissions of road transport while executing a construction project. The purpose of this study is to investigate the changes in the road pollutant emissions when the old diesel vehicles for transporting building materials are replaced according to enhanced pollutant emission regulations. In this study, we found that approximately 89, 64, 77, and 64% of NOx, VOC, PM, and CO, respectively, were emitted during transportation of building materials as a proportion of the emissions during the construction of the structure. The analyzed results also show that about 10, 35, 23, and 35% of NOx, VOC, PM, and CO, respectively, were generated from material transportation as a proportion of the emissions from finishing the work. It is expected that a reduction in pollutant emissions from transporting building materials of up to approximately 64, 39, 49, and 27% of NOx, VOC, PM, and CO, respectively, can be achieved when vehicles registered before 2003 are replaced with ones that adhere to the tightened regulations.

Abstract. Black carbon (BC) is a significant climate forcer with a particularly pronounced forcing effect in polar regions such as the Russian Arctic. Diesel combustion is a major global source of BC emissions, accounting for 25–30 % of all BC emissions. While the demand for diesel is growing in Russia, the country's diesel emissions are poorly understood. This paper presents a detailed inventory of Russian BC emissions from diesel sources. Drawing on a complete Russian vehicle registry with detailed information about vehicle types and emission standards, this paper analyzes BC emissions from diesel on-road vehicles. We use the COPERT emission model (COmputer Programme to calculate Emissions from Road Transport) with Russia-specific emission factors for all types of on-road vehicles. On-road diesel vehicles emitted 21 Gg of BC in 2014: heavy-duty trucks account for 60 % of the on-road BC emissions, while cars represent only 5 % (light commercial vehicles and buses account for the remainder). Using Russian activity data and fuel-based emission factors, the paper also presents BC emissions from diesel locomotives and ships, off-road engines in industry, construction and agriculture, and generators. The study also factors in the role of superemitters in BC emissions from diesel on-road vehicles and off-road sources. The total emissions from diesel sources in Russia are estimated to be 49 Gg of BC and 17 Gg of organic carbon (OC) in 2014. Off-road diesel sources emitted 58 % of all diesel BC in Russia.

Introduction. In order to the road to be durable at the minimum necessary cost for its construction, the topsoil should be carefully removed without disturbing the soil located under the topsoil. The problem of cheapening the roads construction without reducing their quality can be solved by creating a continuous unit for the formation of the underlying layer. The main working elemens of the unit are shovels. The blade of the cantilever knife fixed on the shovel cuts the topsoil from the bottom. It is located at the angle of 45 ° to the direction of movement of the shovel and also has a sharpening angle. The front angle of the blade of the cantilever knife.The method of research. The cantilever knife is divided into the elements: the edge of the blade, the upper face of the blade, the surface of the cantilever knife, a lower plane. The consecutive impact of many cantilever knives on the ground within the operating unit width with the ground of one notional cantilever knife at a distance necessary for the excavation of one cubic meter of soil was replaced. The interacting forces of a notional cantilever knife with soil are called notional forces. The methodology of calculating energy costs when penetrating the edge of the blade of the cantilever knife into the soil is presented: to separate a layer from the body of the soil, to create a gap in the body of the soil, to overcome the friction of the soil against the edge of a blade of a cantilever knife. The total energy consumption during the interaction of a edge of a blade of a cantilever knife in the soil excavation with a volume of one cubic meter was obtained by adding the particular energy consumption.Results. Based on the developed calculation method, the distance at which a cantilever knife has to move to excavate one cubic meter of soil, and the time of this movement determined. The energy costs are calculated when penetrating the edge of the blade of the cantilever knife into the soil: to separate a layer from the body of soil, to create a gap in the body of soil, to overcome the friction of the soil against the edge of a blade of a cantilever knife. The total energy consumption and their structure during the interaction of the edge of a blade of a cantilever knife with the soil during the soil excavation with a volume of one cubic meter are determined.Conclusion. The total energy consumption during the interaction of an edge of a blade of a cantilever knife with the soil during the development of soil with a volume of one cubic meter is about 7 thousand J/cubic meter. In the energy costs structure during the interaction of an edge of a blade of a cantilever knife with the soil, energy costs prevail to overcome the friction of the soil against an edge of a blade. To determine the total energy consumption for cutting soil with cantilever knives shovels of the unit for removing the upper soil layer from the underlying layer of a road, it is necessary to analyze the interaction of other elements of cantilever knives with the soil.Financial transparency: the authors have no financial interest in the presented materials or methods. There is no conflict of interest.

Human activity since the industrial revolution through the use of fossil fuels is changing the natural composition of the atmosphere increasing the so called Greenhouse Gases (GHG). Extremadura’s government decided to react actively towards the predicted climatic variations and for that the “Strategy for Climatic Change for Extremadura” (2009-2012) was approved, which marked the strategies to follow regarding the mitigation and adaptation to climate change. Among the strategies some concrete measures are included like developing annual inventories of GHG emissions and contributing to the development and demonstration of innovative approaches, technology methods and instruments. With this objective in mind, we develop this investigation where data and conclusions dealing with the savings of CO2 emissions are given through a comparison of the actual freight transport in the area of influence of the line Badajoz-Puertollano with various scenarios of exploitation for the new planned infrastructures. The savings of the emissions will be caused by: -       The lowering of the emission factors (kg CO2/t·km) in the upgraded railway line in respect to the actual one. -       The commissioning of the upgraded line will reduce the number of lorries circulating on roads, whose emission factors in unitary terms are far more superior to those ones which will be produced by the use of the new railways. The research concludes that the commissioning of the corridor will delete 863,000 transport operations on lorries for a five-year period, reducing the CO2 emissions in relation with the road: a 59% if the traction is diesel and an 82% if it is electric.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3505

The chapter deals with the road transport optimization and estimation of reduced CO2 emissions. To reduce the latter, several approaches were adopted, like alternative technologies, sustainable community changes, and changes in driving behavior. Another possible approach is to reduce the vehicle miles of traveled (VMT) by the means of transport optimization. In this chapter, the heuristic optimization approach for VMT reduction is firstly presented and tested for the case of School Bus Routing Problem. Afterwards, main focus is dedicated to the models for estimation of reduced CO2 emissions. Herein, MEET emission model is integrated into the Monte Carlo based scenario playing algorithm, which calculates the total CO2 emissions in the dependence of the randomly independently changing average speeds of the vehicles of the driving fleet. This algorithm is applied to the optimized situation, and the calculated results are compared with the unoptimized case. Results show that the applied optimization concept can significantly reduce the CO2 emissions compared to unoptimized conditions.

The trends of energy consumption and the sources of the associated emissions over the past two decades in the United Kingdom have been analysed. There are indications that the levels of emission of CO 2, NOx, CO, VOCs (volatile organic compounds) and black smoke are rising steadily as a result of energy consumption. The road transport sector emerges as the current overall major contributor of these pollutants and the likely candidate to remain as the fastest growing energy consumer and polluter for some years to come. With the current rate of increase in the number of motor cars, that is 3.9 per cent per annum, and the likely environmental consequences, immediate technological solutions to reduce transport pollution are strongly recommended.
