The increase in industrialization, climatic changes, globalization, urbanization and the decrease in environmental quality due to the combination of many other factors have led to the creation of a new field of study in order to reveal the effects of economic activities on the environment by bringing economics and environmental science closer. The effect of environmental pollution and economic activities on each other has started to attract more attention with development economics. Increases in the use of natural resources such as oil, energy and coal accelerated environmental degradation and brought along concerns about the sustainability of development. In this study, the validity of the Environmental Kuznets Curve Hypothesis was investigated using the quadratic form with the help of ARDL Bounds Test, based on the annual data for the 1975-2018 period for the Turkish Economy. In the model, the relations between ecological footprint and GDP per capita were tried to be revealed; According to the findings, positive and negative relationships were determined between Y, Y2, variables and ecological footprint in the long term, respectively. The results support the Environmental Kuznets Curve Hypothesis. In addition to ARDL cointegration analysis, Toda-Yamamoto causality test was conducted to strengthen the findings and a unidirectional causality relationship was found from economic growth to environmental pollution.
