Abstract:The present study incorporates globalization and energy intensity into the CO 2 emissions function and investigates the presence of Environmental Kuznets Curve (EKC) in 19 African countries for the time period of 1971-2012. We have applied the ARDL bounds testing approach to cointegration to examine the long run relationship in the variables. Our results confirmed the presence of cointegration between the series in Africa, Algeria, Angola, Cameroon, Congo Republic, Ghana, Kenya, Libya, Morocco, Nigeria, South Africa, Sudan, Tanzania, Togo, Tunisia, Zambia and Zimbabwe. The results indicated the positive effect of energy intensity on CO 2 emissions in Africa, Algeria, Angola, Cameroon, Congo Republic, Ghana, Kenya, Libya, Morocco, Nigeria, South Africa, Sudan, Togo, and Tunisia while energy intensity declines CO 2 emissions in the case of Zambia and Zimbabwe. Globalization decreases CO 2 emissions in Africa, Angola, Cameroon, Congo Republic, Egypt, Kenya, Libya, Tunisia and Zambia but increases CO 2 emissions in Ghana, Morocco, South Africa, Sudan and Tanzania. The EKC exists in Africa, Algeria, Cameroon, Congo Republic, Morocco, Tunisia and Zambia but Ushaped relationship is found between economic growth and CO 2 emissions in Sudan and Tanzania.
