Abstract The article proves the necessity and expediency of using financial leasing by extractive industry enterprises to minimize the cost of purchasing, using, maintaining equipment and maintaining production capacity. Foreign and domestic financial leasing practices analyzed and their direct impact on the development of the country’s economy is determined. Financial leasing will become more accessible and understandable for enterprises of different sectors of the economy after the entry into force of the Law of Ukraine “On Financial Leasing”. The analysis of the value of the concluded financial leasing agreements by sectors of the economy carried out and their basic tendencies defined. It is determined that the volume of concluded financial leasing agreements by extractive industry enterprises has a small share in comparison with other branches of economy. The analysis of the effectiveness of structural changes confirm the low demand for financial leasing by extractive industry enterprises. It is determined that the use of financial leasing by extractive industry enterprises will expand existing production, introduce the latest technologies, minimize costs for the purchase, use, maintenance and upgrade of equipment and means of production.

The paper represents the analysis, which has helped to establish the usage of gas hydrate technologies in the methane conversion. This gas could be obtained in different ways. Possibilities and sources for the gas obtaining have been demonstrated. Use of other environmentally friendly sources to support operation in such systems in terms of joint energy complex has been considered. The necessary kinetic connections to provide operational sustainability of all the constituents have been given. The approach helps evaluate quantitatively the priority of its physicochemical transformations to obtain gas hydrates artificially. It is possible to transport methane at considerable distances when it is solidified. Actually, in this case there is no necessity to build costly compressor stations and pipelines for its transportation to consumers. The approach is extremely important for mining regions as it helps prolong the operating period and working out of the abandoned and off-balance coal reserves. In this case, it is proposed to apply special gasification technologies tending to maximum methane recovery. The proposed solutions give the possibility to define the trends of our further research. They will be highlighted in the following authors’ studies.

The article is devoted to main theoretical and practical questions concerning “green” investments in logistics infrastructure objects. This type of investments has certain peculiarities as it deals with the sphere which is related to any kind of business and human’s activity. Logistic infrastructure forms mobility. But no significant change in a separate facility will not give a significant result without a support to the relevant network and the highest intellectual level of its use. Planning of logistic infrastructure should be performed in such way that the positive effect on economic growth was maximal, and the negative impact on the environment is minimal. Thant’s why improving logistics infrastructure facilitates achieving sustainable goals as it works simultaneously for economic, environmental and social development. Thus it is extremely important to implement such tool from “green” economy concept as “green” investments towards logistics infrastructure objects. There were analyzed different theoretical approaches to the definition of “green” investments in the paper. The result of deep research of worlds’ best practical trends for “green” investing in logistics infrastructure objects is provided. There studied separately mentioned tendencies for all subtypes of hard logistics infrastructure: transport (electrification of vehicles, low-carbon transport systems, sustainable fuels), warehouse (automation, distribution centers decentralization, energy-efficient equipment and construction), packaging (suitable for processing packaging materials, moving from plastic to more environmental types of packaging), information infrastructure (energy-efficient servers, cloud computing, reducing the number of toxic materials and water required for the production of electronic devices), customs (The Green Customs Initiative), social (smart containers, automated food waste tracking systems and automated technologies of optical scanning). Also were studied main instruments to attract necessary finance support for “green” investments and analyzed ways how to implement them in Ukrainian market with its peculiarities.

This paper focuses on the visualization of eco problems and the latest green technologies, including energy-saving. Today, there are four color-graphic means in advertising: photography, graphics (drawing or computer graphics), font compositions, and often a combination of these. Our study considers the imagery and stylistics of eco poster as a type of public advertising, and ascertains that in the subject of energy-saving a light bulb as the visual stereotype prevails. The paper indicates the importance of system design thinking, the use of creative approaches in the educational process of designers (metaphor, metonymy, hyperbole, association, allegory also) in creating social appeals for a wide audience – from young children to the older generation. Moreover, it emphasized the social value of design, and the aesthetic, moral as well as communicative aspects of visual information of environmental orientation within the context of this study.

Abstract Smart building concepts are a relevant topic for the Ukrainian building sector. Although the current policy is mostly dedicated to the improvement of the current energy-saving situation in the building stock, the concept discussed could provide valuable inputs in the realization of the existing strategy. For an assessment of the expected positive impact of the implementation of smart indicators on building operation and renovation processes, as well as the predictions of scenarios of the range of the application of smart instruments, the research presented proposes a thorough analysis of the building stock in Ukraine and, in a real pilot case, the assessment of smart-readiness indicators (SRI) for a complex multi-family building. The case scenarios used, which are derived on the basis of SRI and a processed questionnaire among the habitants, are considered as the reference foundation for a practical application and disseminating the concept for similar cases.

The paper presents the comparative analysis of the amount of waste generated in Ukraine and European countries (except for radioactive waste) based on the official EU and Ukrainian statistical data. The data on waste generation are compiled according to the following classification: by economic activity and household, waste category, grades of hazard, and regions. In Ukraine, 352.3 million tons of waste was generated in 2018. By 2018, almost 13 billion tons of waste had been accumulated at the managed dumpsites, including about 12 million tons of hazardous and over 200 million tons of household waste. In the European Union, 2.6 billion tons of waste was generated in 2018. Over 70% of it was generated by 10 countries: Germany, France, England, Poland, Romania, Italy, Sweden, the Netherlands, Spain and Finland. By economic activity, the largest amounts of waste in Ukraine are generated by the mineral extraction and processing industry, the smallest – from water treatment and construction. In the EU countries, these values are somewhat different. For example, in Germany and France, the largest amounts of waste are generated from construction and manufacturing, the smallest – from agriculture, forestry and fishery. By waste category, the waste generated both in the EU countries and in Ukraine is mineral and solid waste. In Ukraine, the largest amounts of waste are produced and accumulated in the Dnipropetrovsk, Donetsk and Zaporizhzhia regions which accommodate large enterprises for extraction and mineral processing of iron and manganese ores, titanium-zirconium placers, coal, dolomite, and metallurgical limestone, as well as metallurgical and ferroalloy plants.

The purpose of this article is to analyze the efficiency of management of an apartment building in the context of energy efficiency. The article describes the conduct of an energy audit for apartment buildings, which allows a thorough assessment of this problem and identify optimal ways to save energy resources by apartment buildings. Energy audit is a special examination of residential buildings or enterprises, conducted by specialized specialists in energy certification of buildings to determine their technical condition and energy efficiency. Methodology. Within the framework of this article, the results of a sociological survey conducted among the heads of condominiums to analyze the level of their interest in the implementation of energy efficiency measures were analyzed. The value of the cost of 1 apartment for the implementation of the energy modernization project is calculated. Currently, "energy efficiency" and "energy saving" are extremely popular in Ukraine, due to the following: increasing the cost of energy resources;limited financial capacity of vulnerable groups to pay for services. Results of the survey showed an insufficient level of implementation of energy-saving technologies, although the level of interest of apartment building heads is very high. The development of energy efficiency programs for an apartment building is carried out not only taking into account the necessary priority measures, but also based on the financial capacity of the co-owners of the apartment building. The reason for the insufficient implementation of energy saving measures is the insufficient financial capacity of co-owners and, as a consequence, the apartment buildings themselves. State support for the implementation of energy efficiency in the management of apartment buildings has been studied in detail. It is concluded that large-scale involvement of apartment buildings in the implementation of energy efficiency programs is constrained by the following problems: insufficient funding; insufficient state support for project financing; distrust of co-owners to the effectiveness of the project; unsatisfactory condition of the apartment building, which requires significant financial costs. The growth rate of the number of condominium applications shows an increase in public confidence in the Program. However, they are not enough to talk about launching large-scale energy modernization of multi-apartment housing. Financial support of local authorities to their residents in the implementation of energy saving measures will contribute to even better results.
