This article highlights the impact of innovation on achieving environmental sustainability of regional economic systems in the context of effective man-agement of significantly limited natural resources in modern Ukraine, which was the subject of the study, its key objective and main task. Methodology. The proposed work uses systemic and synergetic approaches, methods of analysis and synthesis, induction and deduction, historical and comparative analysis, etc. Value/originality. Consideration of the issues of regional innova-tion and environmental sustainability of regional economic systems in their combination is a novelty in modern studies of ecological-economic processes. It is exhaustively taken into account that innovation is a complex process of transformation of newly obtained ideas and goals into an actual object of eco-nomic relations. At the same time, it was found that in the conditions of trans-formation of the modern Ukrainian economy began to manifest such features as frequent and unpredictable changes in demand due to the emergence of completely new needs, which can be satisfied only by qualitatively new, pre-dominantly knowledge-intensive products. Therefore, there is an urgent need to restructure regional economies on a fundamentally new basis, which provides a real opportunity to reproduce the existing innovation potential, improve the innovation and technological level of all spheres of economic activity in the re-gion and achieve a much higher degree of competitiveness. At the same time, given the significant role of innovation processes in improving and ensuring the proper environmental sustainability of regional eco-nomic systems, the def-inition of appropriate tasks, taking into account their characteristics, is a pre-requisite for the effective management of natural resources of the country as a whole and its regions. Therefore, in European practice, the European Innova-tion Scoreboard (EIS), calculated by Eurostat, is used to determine the achieved level of regional innovation development. At the same time, the methodology used in its basis to assess the effectiveness of national research innovative projects is not without criticism. And one of the main criticisms was the absence of a conceptual or theoretical model of innovation. Simultane-ously, this paper proposes a fundamentally new approach to determining the effectiveness of innovation in the hierarchical-regional dimension, which is based on the use of appropriate tools of multidimensional statistical analysis and statistics of the European Union (in particular, Eurostat) and the State Statistics Service of Ukraine. In addition, synchronously with their standardi-zation, based on the obtained values of innovation levels in the regions, matri-ces were formed separately for incoming and outgoing regional innovation in-dices. Result. The achieved levels of innovativeness of Ukrainian regions in the context of ensuring appropriate environmental sustainability of their economic systems in the management of significantly limited natural resources were de-termined. Practical implications. Another real opportunity has arisen to signif-icantly improve the management of the available natural resources of each re-gion and the state as a whole in terms of ensuring the proper environmental sustainability of regional economic systems.

The article is devoted to a study of the issues related to the processes of reducing the greenhouse gas emissions using different types of biofuels. The dynamics of carbon dioxide emissions in the global energy sector were analyzed and it was determined that a stable level of the CO2 emissions in the last three years is due to introduction of the technologies with the use of renewable energy sources by developed countries. It was proven that the assessment of total greenhouse gas emissions requires an analysis of emissions throughout the life cycle of a biofuel. The impact of a biofuel on the climate change depends on the raw material from which it is produced, and which has a decisive influence on its chemical composition and performance. It was established that a significant role in ensuring energy security and preventing climate change is attributed to the development of biotechnologies, unrelated to the risks of agricultural production. The use of a biofuel from lignocellulose raw material may be more efficient in terms of reducing the greenhouse gas emissions. A biofuel, obtained from the processing of microalgae, also has important prospects. The ability of microalgae to bind atmospheric carbon dioxide may have a positive effect on solving the problem of greenhouse effect.

A circular economy emerged as an alternative transition model, which is considered to be a solution to massive environmental degradation. The transition from a linear economy to a circular economy requires companies to be actively involved in more sustainable practices. For such a transition, companies must rethink, innovate on business models, and encourage sustainability-oriented innovation to deliver customer value, while simultaneously considering environmental and social aspects. On the other hand, the role of the circular economy in energy conservation and infrastructure has not been mapped out in the current literature. This systematic literature review seeks to map out the main interrelated topics of the circular economy and sustainability-oriented innovation, describing internal and external factors that need to be considered in the transition to a clean energy future. Key lines of research are identified, and suggestions for future research and for how to facilitate the movement towards a circular economy are provided. This study contributes to an enhancement of the literature by identifying priority areas regarding the circular economy and sustainability-oriented innovation to encourage future research that contributes to sustainability and environmental preservation.

The noise problem in hotel rooms is strictly connected to noise generated by heating, ventilating, and air conditioning (HVAC) devices. Hospitality industry companies in many countries have specific requirements and monitor the noise level with technical equipment inside the hotel room. To ensure an adequately low level of noise from the HVAC system, proper calculations and tests are performed before the final application of the system in the hotel room. One of the best methods for assessing the noise level from HVAC devices in hotel rooms is to create a testing room (mock-up) in a certain available space, e.g., in a warehouse, and to perform appropriate standard measurements for the noise level. This method is a popular choice in the hotel industry because the noise level can not only be verified, but also, the installation and operation of the HVAC system inside the room can be checked. The main factors in choosing the space in which the mock-up will be made are availability and appropriate volume. It is not always possible to provide a hall space with a very low background level of noise. This article shows that the selection of a mock-up space is also determined by the noise level in the selected space. The background noise level—thus, the noise level in the mock-up room—must be low enough to be able to reliably measure the noise level from the HVAC equipment to avoid the phenomenon of acoustic masking by other noise sources (background noise) not related to the measurement. Background noise at too high a level will lead to invalidation of the measurement results or overestimation of the actual noise level in the room from the tested HVAC devices. In this study, background noise level measurements made in the testing rooms are described. The results are discussed, and a conclusion is drawn.

The effects of clinostating on physiological processes and biochemical characteristics of wheat plants (Triticum aestivum L.) both healthy and infected by the wheat streak mosaic virus (WSMV) were studied. In six experiments, each lasting over 30 days, healthy and infected plants of the dwarf Apogee variety were grown under conditions of continuous horizontal and vertical clinostating with 2 rpm at 21 +/- 2 degrees C and 6000 1x (the optimal moisture of a substrate being maintained). The control variants (healthy and infected) were simultaneously grown under the same conditions of temperature and illumination in stationary containers and in open pots. During the experiment, visual observations were carried out over the state of tested plants. After completing the experiment, biometric indices, pigment, carbohydrate and dry matter contents were determined in all the plants. It was shown that clinostating sharply reduced the reproductive function of healthy plants and considerably affected their biomass (productivity) and concentration of chlorophylls and sugars. The viral infection resulted in further reduction of these characteristics. In control variants the viral effect was more significant. We speculate that clinostating reduced the rate of reproduction and spread of the virus.

Abstract The study aims to substantiate theoretical and methodological aspects of the use of strategic environmental assessment as an instrument for public regulation of the ecological status of territories. The research methodology is based on using a systematic approach for conducting a strategic environmental assessment of the possibility of environmental problems and threats posed by the implementation of long-term projects and current activities. The development of ecological balance, comparison of the results of normative and exploratory forecasts of the state of the environment become the basis for the formation of goals of strategic environmental management, the appearance of a set of measures for the conservation and restoration of natural resources. Identification of factors influencing the state of the environment is a necessary condition for the prevention of pollution of territories, inefficient use of natural resources, justification of the essential measures of state regulation to ensure the achievement of goals. The practical experience of assessing the achievements in the management of the conditions of the environment is illustrated by the example of regions of Ukraine. The proposed approach to the development of the ecological balance and the methodology of complex assessment of the ecological status of the territory have scientific novelty and contribute to the assessment of the effectiveness of public administration balanced development of the territories.

The relevance of the analysis of Sustainable Development Goals is based on the 2030 Agenda for Sustainable Development. The purpose of the study is to create a model of management/regulation of the quality of education and scientific research systems based on Sustainable Development Goals. The data of the ratings that reflect certain tasks of the Sustainable Development Goals, including those related to educational and scientific activities, are analyzed. The methodology of calculating the index of the success of realization of separate purposes of sustainable development is used. Bibliometric analysis as a research tool is used to create a quality of education management model. The example of the roadmap for achieving SDGs within the relationship chain “quality of education and science + partnership and networks–innovation–socio-economic impact–sustainable development goals” is provided. The suggested methodology for determining the index of success in achieving Sustainable Development Goals includes managing education systems, implementing scientific research, and managing/regulating the economy on micro-(university), meso-(regional), and macro-(national) levels. The tool in this case is a strategy for achieving KPIs, which can be fundamentally implemented in the form of a roadmap, with detailing of its elements using other tools. The “management/regulation” stage of the process of achieving Sustainable Development Goals is concretized by a mind map.

Abstract Ukraine stands on the threshold of economic development and outdated habits. At the same time, the situation with landfills and ecologically oriented productions is much wider than in Western countries. But thanks to the popularity of the transition to alternative energy sources, even the country’s population already partially uses it. The aquaculture sector is one of the promising areas of the Ukrainian economy. Currently, it is only taking its modern form. This study examines the prospects for the development of the aquaculture sector in the circular economy, as a reliable pillar of Ukraine’s food security in the long term. Weaknesses and opportunities of the sector, as well as pre-war growth trends, are identified. A number of recommendations are also offered to direct attention to the issues of the sector.
