Nowadays the issue of reducing environmental pollution is on the agenda of all countries. Among the areas that have huge negative consequences for nature, logistics and supply chains take their place

Internal costs refer to the direct monetised costs for a person or organisation undertaking an activity. They are costs that a business bases its price on. External costs are not included in price and consist on the cost of disposing of the product at the end of its useful life, the environmental degradation caused by the emissions, pollutants and wastes from production, the cost of health problems caused by harmful materials and ingredients and social costs associated with increasing unemployment due to increasing automation. In such way, external costs or externalities refer to the economic concept of uncompensated social or environmental effects. The countries of the European Union have long been engaged in converting indirect losses from transport into financial units. The latest existing 2019 Handbook on External Costs of Transport considers not only marginal external costs, but also total and average external transport costs across the EU, Switzerland and Norway. Our goals in this research are: - identification of factors that have a significant impact on the total external costs of transport at the country level; - determining of the degree of such influence; - determination of interdependence (multicollinearity) of factors of influence; - determination of the direction of influence (direct or inverse dependence); - making conclusions regarding the possibility of determining the external costs of the country based on the selected factors. On the basis of correlation-regression analysis, factors were determined that have a clear relationship with the external costs of road transport - the country's GDP, the amount of transport work produced by the country in tkm and the amount invested in road infrastructure. Values of Multiple R and R-square of the regression model (very next to 1) allow us to make a conclusion that these three factors are sufficient to explain the variable (external costs) at a reliability level of 95%. All factors are statistically significant and should be involved in the model. Another important result is the sign with which the coefficients are present in the model: with an increase in % of GDP and transport work, external costs will increase, however, with an increase in investment in road infrastructure, the value of external costs of transport will decrease. Finally, the regression equation of the country's external transport costs as a function of the three aforementioned indicators was obtained. A very good representation of the statistical data with the resulting regression model can be observed. It can be assumed that this model can be used to predict external costs of road transport and transfer the methodology to countries outside the EU, for example, Ukraine..

The article reveals the essence of the conceptual approach to "green" technologies in the logistics activities of enterprises. The concept of "green" technologies has been clarified as technologies that use environmentally safe production processes and supply chains in comparison with the production methods traditionally used at enterprises. The role and opportunities of Ukrainian environmental logistics in the European Green Deal have been studied. It has been established that the European Green Deal is a program of the European Union aimed at protecting the climate and the environment. This program is aimed at making the economies of the European Union countries more resource-efficient, canceling greenhouse gas emissions by 2050 and separating economic growth from the use of natural resources. Currently, Ukraine is only planning to join the European Green Deal, declaring in the National Economic Strategy the intention to achieve climate neutrality by 2060. The state and general trends of the development of strategic logistics infrastructure projects of Ukraine in the context of the implementation of the Green Deal and Digital Europe programs are analyzed. The Europian Green Deal is a dynamic instrument that is at the stage of formation. The purpose of the article is the development of theoretical and methodological foundations, applied recommendations regarding the prospects of "green" technologies in the logistics activities of Ukrainian enterprises: their concepts and features of implementation within the framework of the European Green Deal and Digital Europe programs, "European Union for the Environment" (EU4Environment), development of sustainable logistics in Ukraine, features of application in specific logistics processes, problems and prospects, logistics strategy of Ukrainian enterprises. The process of applying "green" technologies in supply chain management is analyzed. In the logistics chain, processes related to supply, production, warehousing, transportation and distribution are involved, therefore, logistics activities are focused not only on the internal business processes of the enterprise, but also have a significant impact on the environment and contribute to the emergence of negative environmental consequences. In connection with the above, the concept of "green" (sustainable) supply chains, which provides for a minimal harmful impact on the environment during the implementation of logistics business processes, has recently become widespread.

Quality of transport infrastructure determines the quality of the provision of services for the transportation of goods and passengers. The infrastructure sector is a guarantee of efficiency, mobility and uninterrupted economic activity. However, the high quality of the transport infrastructure implies significant and long-term investments. According to a McKinsey research report, to support sustainable economic growth in the world in line with forecasts for 2030, it is necessary to cover the need for additional investment of $ 3.3 trillion annually, equivalent to 3.8% of world GDP. The purpose of this work is to analyze the existing European approach to assessing transport infrastructure expenditures and costs, their impact on transport performance at the country level, as well as trends in Ukrainian policy regarding the support and development of road infrastructure. Transport infrastructure costs include the investment in new infrastructure, the cost of upgrading the existing infrastructure, the cost of maintaining the infrastructure, and the operating costs to enable the use of the transport infrastructure. Directive 2011/76 / EU prescribes that the weighted average infrastructure charges should be linked to construction costs, as well as the costs of operation, maintenance and development of the corresponding infrastructure network. The official Eurostat data of investment and O&M costs of transport infrastructure based on the citizenship principle was taken for this study, namely: - the number of ton-kilometers traveled per year; - the volume of investments in road infrastructure per year; - the amount of funds for the maintenance of road infrastructure per year. The indicators were taken for countries of the EU for which statistics were available for 2016 and 2019. According to the study, the effect of investments in transport infrastructure is strongly manifested both in the same year and affects subsequent years in terms of the volume of annual transport work. That is, an increase in investment in road infrastructure clearly has a positive effect on the volume of transport work performed. On the other hand, the volume of investments in the EU infrastructure brings a much greater positive effect than funds for road maintenance. Thus, the experience of developed countries shows a positive relationship between investment in the maintenance and construction of transport infrastructure and economic performance of the state. Part of the research was devoted to the study of the impact of investments in road infrastructure of Ukraine on the example of the global Ukrainian infrastructure project "Big Construction". It is projected that in 2024, thanks to road works under the Big Construction, Ukraine's GDP will be 4.4% higher than GDP in 2020. But, as the research shows, good transport infrastructure is a necessary, but not a sufficient condition for growth. "Big Construction" project in Ukraine does not show any positive effect on the volume of performed internal transport work now. The reasons may lie both in more long-term effect from improving the infrastructure, and in the facts of corruption and theft of funds allocated for the project.

Road transport is one of the most important elements of the functioning of a modern city. Maneuverability, mobility, speed of delivery of goods and other criteria have provided him with a special and leading place in urban logistics. However, along with the benefits of a developed transport network for society, its progress is accompanied by negative consequences for the environment and the population of the city. High rates of growth in the number of cars, especially in large cities, cause an increase in emissions of harmful products into the atmosphere, which, accordingly, negatively affects the health of the population. Consequently, the problem of environmental pollution in large cities from harmful emissions from vehicles requires an urgent solution. The increase in emissions of harmful substances is affected by an increase in the consumption of fuel materials due to a decrease in speed because of an increase in traffic density in the city. The frequency, duration, prevalence of congestion is increasing along with the urbanization of the population and the increase in the number of cars in cities. The dense development of the central historical districts of the city exacerbates the problem of unhindered passage of individual, public and freight vehicles. In addition, a decrease in the speed of city traffic affects the speed of delivery of goods, correspondence, etc., which negatively affects the speed of business processes, and ultimately worsens the level of logistics services for customers. The purpose of this study is to analyze the current situation in terms of the dynamics of the average speed of the city's traffic flow by hours of the day and to obtain a mathematical model of the dependence of the speed of movement on the consumption of fuel materials for various environmentally friendly means of urban delivery (car, motorcycle, bicycle and pedestrian courier). The research was carried out in two stages. At the first, the study of the dependence of the average speed of movement in the city on the time of day (for all means of city delivery) was carried out. At the second stage, the study of the dependence of the average consumption of fuel materials in the city (which, accordingly, is a function of the speed of movement) on the time of day for motorized urban delivery vehicles was done. In the course of the study, at each stage, an equation of the trend lines was obtained with a sufficient approximation accuracy. In conclusion, the study proposes an algorithm for determining the average speed and average amount of fuel consumption when delivering small consignments in an urban environment using four urban logistics means - a car, a motorcycle, a bicycle, and a pedestrian courier (with the possibility of using public transport). The proposed algorithm can be applied in any delivery conditions in the city.

The article considers the issue of return flow management in supply chains. Recently, this problem has become particularly acute due to growing economic losses and social, economic and security threats, a sharp increase in the return of unused, substandard, end-of-life products, hazardous and hazardous waste, materials for recycling and regeneration. This link of business processes was not even distinguished in the structure of the supply chain before. Based on the analysis of the theory and practice of recycling, resource conservation, recycling and disposal, the authors concluded that it is necessary to form a closed supply chain with the participation of reversible flows and based on the concept of product life cycle. The example of Ukraine illustrates the current situation with the formation and accumulation and processing of waste production and life due to the actual lack of reverse logistics services. The paper develops a comprehensive scheme-structure of existing problems of reverse logistics and offers specific recommendations for solving problems of reverse logistics management in Ukraine. Each aspect of improving the management system considered from the standpoint of economic, social, environmental, technical and technological efficiency. Particular attention paid to the relevant educational work with the population on ways to implement the principles of reversible logistics, improving the culture of consumption together with the introduction of legal and social responsibility.

One of the main directions for improving the quality of the provision of transport services is to bring the level of service and infrastructure development to European standards, increase the level of safety and reduce the negative impact on the environment. Accordingly, the role of an integrated consideration of logistics solutions increases; rationality is no longer considered only in economic terms (expenses, income, payback period, etc.), but also in terms of the impact on the surrounding social and natural environment (harmful emissions, road accidents, traffic congestion, noise, etc.). The purpose of the article is to examine the LTL cargo delivery system in terms of various components of economic and socio-environmental impacts and associated costs. The authors analyze and gives their own vision of the basic terminology and concepts related to the transportation of LTL cargo. The existing demand for LTL cargo transportation between regions of Ukraine has been analyzed and a significant (more than 50%) share of demand for such transportation among the total number of requests for delivery between regions of the country has been determined. The process of LTL cargo delivery is considered on the basis of the interaction of the relevant stakeholders, the list and characteristics of which are determined for a consolidated and non-consolidated delivery technology. The main attention is paid to the assessment of the system of economic and socio-ecological interactions accompanying the delivery process, as well as the corresponding costs and losses. The main components of costs are stated, which, according to the authors, should be taken into account when assessing the feasibility of applying a particular scheme of LTL cargo delivery. A set of factors that affect the boundaries of the expediency of using the consolidated technology of LTL cargo .
