The GCC countries’ unified economic agreement which has been signed on 1981 and activated in 2002 aimed for easing free trade and attract more FDI to enhance the level of economic growth. This agreement has also emphasized on reducing levels of pollution and achieving a sustainable economic growth. In reality, there is an increase in the level of emissions along with the level of rising of economic growth in GCC countries. Accordingly, in this study we will test the most significant variables pertaining to the increasing carbon dioxide emissions in GCC countries. The research objective is to determine how much the FDI inflows, economic growth, and commodity imports influenced the increasing level of emissions, and which variable has most effect? For this purpose, an empirical model is specified as a function of FDI inflows, per capita GDP growth rate, and commodity imports. However, we have built this model based on Environmental Kuznets Curve assumption (EKC), as well as Pollution Haven Hypothesis (PHH). It will be examined simultaneously a 66 balanced observation of the six GCC countries within the panel data technique using cross-section random effects
