The present study investigates the dynamic relationship between energy intensity and CO 2 emissions by incorporating economic growth in environment CO 2 emissions function using data of Sub Saharan African countries. For this purpose, we applied panel cointegration to examine the long run relationship between the series. We employed the VECM Granger causality to test the direction of causality amid the variables. At panel level, our results validate the existence of cointegration among the series. The long run panel results show that energy intensity has positive and statistically significant impact on CO 2 emissions. There is also positive and negative link of non-linear and linear terms of real GDP per capita with CO 2 emissions supporting the presence of environmental Kuznets curve (EKC). The causality analysis reveals the bidirectional causality between economic growth and CO 2 emissions while energy intensity Granger causes economic growth and hence CO 2 emissions, while across the individual countries, the results differ. This paper opens up new insights for policy makers to design comprehensive economic, energy and environmental policy for sustainable long run economic growth. [ABSTRACT FROM AUTHOR]
