This paper deals with the analysis of the statistical properties of the CO2 emissions in Africa using both aggregated and disaggregated data by components (gas, liquid, solid, cement and flaring). The results indicate orders of integration which are in all cases equal to or higher than one, finding thus statistical evidence against the hypothesis of mean reversion, which implies shocks having permanent and/or explosive effects on the series under examination. This is in line with the results obtained by other authors for the developed countries, implying that in the event of shocks producing negative economic effects, strong measured should be adopted by the authorities to recover the original trends.
