In this paper, we examined the relationship between air pollution and economic growth for the case of Tunisia at the beginning of 1970. Our study carried out in particular on the basis of verification of the hypothesis of environmental Kuznets curve by using time series data in VAR model. As indicators of pollution measurement of the area, were chosen, CO2 emissions per capita (PECO2), SO2 emissions per capita (PESO2) and NOx emissions per capita (PENOx). Our dependent variable measuring economic growth is defined by the real per capita GDP (PGDP). We identified a cointegrating relationship between economic growth and the series of emissions. Furthermore, the assumption of CEK has been confirmed for the case of Tunisia, where the mapping showed us a curve in the shape of an inverted U-characterized by a rising phase that peaked when the level GDP was highest to move to a new downward phase where environmental quality is improving over time. First, the amount of GDP according to which CO2 emissions began to decline is estimated at approximately $ 2046.7 or the equivalent of $ 6444.8 (in purchasing power parity (PPP) at constant prices 2005). Second, the turning point of EKC-PESO2 according to which Tunisia has been able to control SO2 emissions was estimated at the value of $ 1528.5 on the amount of $ 4,093.2 (in purchasing power parity (PPP) in constant prices of 2005). Third, in the case of NOx emissions per capita, a new phase decreasing was recorded at CEK-PENOx when real GDP per capita reached a level of $ 1500.6 which is a comparison, similar to $ 4018.6. In terms of the direction of causality, we identified a causal relationship to Granger from GDP to the different emissions which justifies that the implementation of a range of measures protecting the environmental quality of Tunisia should be the top priority in the context of sustainable development and enhancing the long-run growth.
