Abstract :The importance of environmental sustainability stems from its contributions to the present and the future. Protecting biodiversity, achieving healthier conditions by reducing pollution, effectively combating global warming, and using resources efficiently is important for a clean and healthy future. To ensure environmental sustainability, the continuity of environmental measurement models is also required. Therefore, The Environmental Performance Index (EPI), consisting of 11 categories and 40 indicators, is published periodically every year by Yale and Columbia University researchers in partnership with the World Economic Forum. This study aims to perform a regional comparison by compiling EPI reports published between 1995-2022 and to reveal the relationship between country income levels and determined indicators. Within the scope of this study, the most important indicators were first selected with Pareto analysis according to EPI indicator weights. The selected indicators were compared in detail by dividing the 180 countries included in the 1995-2022 EPI report into regions. In the next stage of the study, the relationship of the selected indicators with income level was examined statistically. According to the results of the study, a statistically significant difference was found between the income levels of the countries with the nineteen EPI indicators selected.
