The aim of the research is to use the TOPSIS-Sort methodology, based on a sample of ten countries, in order to classify them into those with acceptable (Class 1) and those with less acceptable (Class 2) EPI values in the field of environmental policy. A sorting procedure has been realized in relation to the reference value determined in accordance with the data of countries. In addition, a sensitivity analysis was performed by changing the benchmark used to classify countries. The results of the conducted analyzes show that under strict criteria for the formation of Class 1, no country can be classified in the class of belonging. Only during the conducted sensitivity analysis and less strict formation of Class 1 do the countries join the belonging class. Greece and Slovenia are the first to be classified in Class 1.enEPITOPSISenvironmental performancesensitivity analysisBalkan countriesconferenceObject
