The present study examines the relationship between economic growth, population and volume of foreign trade and air pollution in the two groups of countries member of the OECD and non-OECD countries using panel data for the period 2010-1971 deals. Indicator of air pollution and greenhouse gas CO2in the transport sector and total sector. Kuznets curve for this purpose air pollution in the form of total CO2and CO2 transport sector were examined and compared. For each of these two sectors, 3 different models estimated that a total of 12 models for these two groups of countries studied were estimated. The results showed that the inverted U curve for total CO2emissions and CO2transport sector, in both groups of member countries of the OECD and non-OECD countries Confirmed but the turning point inverted U curve is different for the two groups of countries together. Curve turning point for US $ 51025.43 Group member states and non-member countries was US $ 6707.73, Compared with the average per capita income for both groups of countries shows that these two groups of countries still have not reached the turning point of the curve but results showed that the tensile member states closer to the back curve.
