Establishment of a correlation between indicators of resource saving and environmental safety

Abstract

Purpose. Determination of the relationship between resource saving indicators and the level of environmental safety in the territories of technogenically loaded regions. The methods. A reasonable choice of indicators of resource conservation and environmental safety at objects or territories necessary for comparative analysis was carried out on the basis of a critical analysis of known indicators and their approbation on a priori statistical data. Determining the degree of correlation between the selected indicators and building a relationship between them was carried out on the basis of correlation, regression and dispersion analysis. Findings. The existing indicators of resource saving and environmental safety required for comparison are analyzed. An indicator of resource conservation in the form of deviate – a difference discrete function between the basic value of the use of natural resources and the actual one, i.e. before and after the implementation of environmental measures, is proposed. The Inhaber air pollution index for the city of Dnipro and the Nikopol agglomeration has been determined. A correlation between environmental protection measures and air quality has been established. The originality. It is shown that the proposed deviation is equivalent to the indicator of resource intensity of production, which is advisable to compare with the indicator of environmental safety in the form of the Inhaber index. The selected index characterizes the emissions of suspended substances (aerosols) and SO2 into the atmosphere per capita, and at the same time the contribution of a certain district (or city) to the overall level of air pollution in the country. Therefore, it is recommended by us for comparison with the resource saving of production in Ukraine. The relationship between the resource saving indicator and the atmospheric pollution index is established in the form of a regression equation: y= 1,3∙106x14,7exp(–14,1x). Its adequacy has been proven. Practical implementation. A number of annual indicators of resource intensity/resource saving of GDP production in Ukraine have been identified and evaluated, and for two cities of the Dnipropetrovsk region, taking into account emissions of pollutants into the atmosphere. The obtained dependence in the form of the above equation can be used in the analysis of environmental activities of enterprises, organizations, territories, and the country as a whole.
