There has been established in the article the correlation and regression relationship between the factors of the country's development and the level of environmental safety on the basis of identifying the patterns of certain factors sets influencing the volume of harmful emissions into the atmosphere. On the basis of modeling, there has been carried out the analysis of individual groups of factors influencing the volumes of harmful emissions in the countries selected for the study. The nature and degree of influence of the selected factors on the resulting indicators (volumes of harmful emissions) have been determined. It has been found that the number of these factors is significantly higher in France than in Ukraine. This is due to both the political and economic situation in the country. The level of energy efficient technologies implementation and environmental restructuring of business entities are no less significant. The ranking of factors has been carried out based on the value of the correlation coefficient within a separate group and each country. There are also highlighted differences in the research results and their reasons
