Abstract


This study examines the causal relationship between carbon dioxide emissions, energy consumption, and economic growth using the recent econometric technique ARDL for sixteen selected African countries over the period 1986-2018. The results of the F-bounds test reveal that there is a long run relationship between variables for the following countries: Benin, Burkina-Faso, Cameroun, Chad, Congo-Democratic-Republic, Congo-Republic, Ghana, Guinea, Guinea-Bissau, Niger, Senegal, Sudan and Togo. There is a positive long run elasticity estimates of carbon emission with respect to energy consumption at 1% significant level in Benin, Burkina-Faso; 5% significant level in Congo Republic and Sudan and at 10% significant level in Senegal. Same with respect to real GDP at 1% significant level in Congo Democratic Republic; negative with respect to the square of per capita real GDP per capita at 1% in Guinea-Bissau and 5% in Cameroun. This means that environmental Kuznets curve hypothesis can be easily used in Guinea-Bissau and Cameroun. No long-run relation has been found for Angola, Gabon and Mali. We investigate as well in the same frame-work the causal relationship between variables using error correction base Granger causality models.
