Emerging markets are rapidly developing and outperforming developed markets in terms of onshore wind and solar power. Moreover, emerging markets are now getting drivers for the enhancement of global renewable energy as they are seen as territories with the greatest potential for expansion of wind and solar capacities. This study aims to investigate the casual links between financial investments by gas and oil giants and long-term vision around clean energy. We analysed various reports on procurement tools used by corporations, purchasing renewable energy. This gave us an idea about the availability and frequent usage of different instruments employed around world. The empirical results show that state support and policy development both have positive impact on state and private investments in the long run. The influence of energy development is more evident in emerging clean energy markets. The findings of the this study suggest that as renewable energy targets price and performance parity with traditional sources around the world, and is getting able to improve grid efficiency thus strengthening its competitive edge with new technologies, the hurdles to its adoption are disappearing.

Our paper focuses on factors that help to successfully and efficiently manage urban infrastructure in large cities and centres using Big Data solutions. We explain the key points about urban Big Data approaches, including infrastructure that supports urban governance, public services and economic and industrial development, taking into account and supporting the central role of urban Big Data in urban intelligence with particular emphasis on the smart cities. Moreover, we want to add a third dimension to social urban data analysis by assessing the use of social, spatial, and temporal data for key issues to understand how it can influence human behaviour across time and space. Our results might have important implications for urban planners and policy-makers and contribute to the mitigating the regional inequalities as well as to improving urban infrastructure and making the cities of the future happier and healthier places for all their citizens.

The article reveals the problems of improving environmental impact assessment and justification of the economic investments of industrial enterprises. The existing tools for environmental impact assessment are analyzed, information on the role and place of environmental impact assessment and investment design in the justification of the planned economic activity is systematized. For this purpose, considerable attention is paid to the analysis and synthesis of existing methodological approaches to this problem. The authors propose to consider environmental impact assessment and justification of environmental investments as a process aimed at making environmentally oriented management decisions on the feasibility and economic feasibility of implementing planned economic activities, the reasonableness of capital investments, taking into account possible adverse environmental, social, economic impacts and developing measures for their reduction and prevention. Based on the study, the authors developed a classification of the causes of environmental pollution, presented in the form of a tree of systems, allowing for a clear decomposition of the causes of pollution of the environment, specifying and refining the targeting of environmental measures necessary to reduce pollution. This research direction is also complemented by the development of a strategy (decision tree) and a mathematical description of the simulation procedure, which allows real-time making an objectively reasonable choice of options for implementing the planned economic activity, taking into account the totality of known information.
