Abstract: This paper employs a STIRPAT model to conduct a long- and short-run analysis for CO2 emissions in Tunisia during the period of 1971-2008, by using a bounds testing approach for a cointegration methodology. The empirical estimates have shown that the population growth brings about CO2-emission rise. Nonetheless, the environmental impact is found to be more pronounced in the short run rather than in the long run. Affluence has the greatest effect on the CO2 emissions in terms of contribution degree to the change of the environmental impact in the long run. Moreover, the rapid decrease in energy intensity, through optimising industrial and energy structures and thus raising the proportion of clean energy sources and improving energy efficiency, seems to be the main cause of restraining the increase in Tunisia's environmental impact. Finally, the carbon intensity impact remains stable in the short and long runs. Against this background, the paper recommends pursuing a well-structured and coherent policy framework for enhancing energy efficiency for CO2 reduction in Tunisia.
