For time series data for the period 1980-2009 taking into account the Environmental Kuznets Curve (EKC) was modeling. The results show that there are N-shaped relationship between CO<sub>2</sub> emissions and economic growth, so these findings do not support EKC hypothesis with inverted-U shaped curve. At this point, because of the presence of a cubic polynomial, <em>regression spline</em> method is used as a different approach and a new model has been proposed. The model gives better results according to different model selection criteria.</p> <p><strong>Keywords: </strong>Environmental Kuznets curve; CO<sub>2</sub> emissions; regression spline; thin plate regression spline</p> <p><strong>JEL Classifications:</strong> C14; C22; Q53; Q56</p> ER -
