This research investigates the existence of relationships between economic growth and carbon emissions in the Organization of Petroleum Exporting Countries (OPEC) for the period of 1960 to 2005. A model relating economic growth and carbon emissions is used to examine the eventual existence of Environmental Kuznets Curve (EKC) hypothesis. To test our hpothesis, the econometric panel data approach is employed. The results indicate that there is a positive relationship between gross domestic product and CO2 emissions. And, with persistence of economic growth this relationship becomes negative. That is, the estimation has given an EKC relationship between GDP and CO2 emissions in these countrries.
