This paper discusses an important issue for today’s mobile world striving for sustainable development, namely ecotourism. The major objective of the study presented in this article was to carry out a comparative analysis of the conventional tourist trip along the Kharkov (Ukraine)–Varna (Bulgaria) route in an electric car and by air transport. The main criteria for comparing two variants of tourist trip were cost price, time, mobility, and incidental cost. The authors used the Pareto method and the shortest distance to the target method. Comparative analysis of the travel options “electric car” and “air transport” by the Pareto method and the method of the shortest distance to the target showed that traveling by electric car is almost one and a half times more profitable than traveling by plane.

The paper is devoted to the development of criteria for the implementation of the principles of “green” and sustainable development of road and transport infrastructure of the cities of Ukraine on the basis of world experience, as well as own research. It is established that the world experience offers a number of systems for assessing environmental friendliness and sustainability of the development of transport infrastructure, which cannot be applied unambiguously and without adaptation in the cities of Ukraine. Therefore, environmentally significant criteria for assessing compliance with the requirements of “green” standards for the development of the city’s transport infrastructure in the context of assessing its life cycle stages, which in the future will help the environmentally balanced development of the city’s transport system were developed and proposed in the paper. As an example of the practical application of the criteria for “green” construction and assessment of environmental sustainability for the development of the road network, a mechanism was developed and proposed to assess the environmental efficiency of the development of the urban bicycle transport network based on estimates of reduced fuel consumption, pollutant emissions and noise levels by replacing motor work with cycling.

Purpose. To identify environmental climatic impacts resulting from the biodiesel fuel use for vehicles (Vs). Methodology. The methods are based on computation of natural resource consumption and toxic emission with the help of environmental footprint calculator being a software program. Findings. The results of integral assessment of the environmental impact (namely, consumption of water, power, natural resources, and emission of greenhouse gases 2, and NOx in terms of such base traction trucks as VOLVO FM, FH, FE, and FL) were computed for biodiesel fuel types 0, 7, 30, 100 depending upon different standards of EURO propellants. Both positive and negative environmental impact factors have been determined for consuming biofuels during full lifecycle of Vs. It has been defined that minor decrease in 2 emission owing to the use of standard modern biodiesel fuel is followed by significant increase in NOx emission as well as power and water consumption in terms of first-generation biodiesel fuel utilization. VOLVO F Vs were applied for comparative analysis of environmental impact by first-generation biodiesel fuel (i.e. 7, 30, 100) and second-generation fuel being hydrotreated vegetable oil (HVO). Similar tendencies were recognized. Moreover, opportunity to apply biodiesel fuels along with other measures decreasing 2 emission was analyzed. Originality. Originality is stipulated by the use of the integrated assessment of impact of vehicles on climate change as well as use of natural resources while applying biodiesel fuel for vehicles. Practical value. It is possible to forecast environmental consequences resulting from the use of various biodiesel fuels for Vs.

The purpose of the work was to identify environmental climatic impacts resulting from the biodiesel fuel use for vehicles (Vs). The methods are based on computation of natural resource consumption and toxic substances emission with the help of environmental footprint calculator being a software program. The results of integral assessment of the environmental impact (namely, consumption of water, pow basic traction trucks as VOLVO FM, FH, FE, and FL) were computed for biodiesel fuel types В0, В7, В30, В100 depending upon different standards of EURO propellants. Both positive and negative environmental impact factors have been determined for consuming biofuels during full lifecycle of Vs. It has been defined that minor decrease in СО2 emission owing to the use of standard modern biodiesel fuel was followed by significant increase in NOx emission, as well as power and water consumption in terms of first-generation biodiesel fuel utilization. Similar tendencies were recognized. Moreover, opportunity to apply biodiesel fuels along with other measures decreasing СО2 emission was analyzed. Originality it is stipulated by the use of the integrated assessment of impact of vehicles on climate change, as well as the use of natural resources while applying biodiesel fuel for vehicles. Keywords: greenhouse effect, biodiesel fuel, life cycle of Vs, nitrogen oxides.
