The purpose of the dissertation is to deepen the theoretical and methodological foundations, methodological approaches and the development of statistical support for assessing, modeling and forecasting the components of environmental safety of Ukraine to form recommendations for its improvement. The object of research is the environmental safety of Ukraine. The subject of research is theoretical and methodological principles, methodological approaches and practical aspects of statistical assessment and modeling of environmental safety. The scientific novelty of the obtained results is that the study allowed to deepen the theoretical and methodological principles of environmental safety assessment, to study the current ecological state of Ukraine, to predict its possible changes and to develop priority practical recommendations for improving environmental safety taking into account the principle of ecological and economic balance. The main results that characterize the novelty of the study and the personal contribution of the applicant are as follows: improved: the conceptual framework of statistical assessment of environmental safety, taking into account the factor of ecological and economic balance, which, unlike existing, implemented a methodological approach to determining the level and cost of elimination environmental safety risks, their modeling and forecasting, which allows to form directions of effective management decisions to improve the level of environmental safety; system of statistical indicators of ecological safety due to the use of indicators of volume, structure and dynamics: the proposed calculation of the cost of eliminating environmental risks per unit of pollution allows to assess the level of potential threats and unreasonable expenditures on environmental measures; methodical approach to statistical assessment of ecological and economic balance based on the calculation of integrated indices of ecological and economic development using the method of multidimensional classification, which allows to quantify the level and dynamics of balance, as well as calculate the impact of each factor on the development of ecological and economic subsystems proportional distribution method; methodical approach to assessing the level and cost of eliminating environmental safety risks, which is based on calculating the value of exceeding the actual levels of pollution over their theoretical values, calculated by trend statistical models of pollutant emissions into the atmosphere, water resources and hazardous waste at the macro level and a scientifically sound way. received further development: the meaning of the concept of "environmental security", which, in contrast to the existing, the observance of ecological and economic balance of the country's development as a key factor. Environmental security reflects a set of conditions and processes that provide all the vital human needs without deteriorating the living conditions of future generations, taking into account the economic and environmental balance of sustainable economic development; the concept of "ecological and economic balance", which provides for a parallel synchronous growth of indices of development of environmental and economic subsystems at the macro level, which allows to maintain the environmental security of the country while ensuring economic efficiency; absolute and relative assessment of environmental safety risks, which allowed to determine the cost of eliminating the risks of air pollution, water bodies and the formation of hazardous waste of I-III classes.
