The objective of this paper is to determine the inflection point of greenhouse gas (CO2) emissions in sub-Saharan African countries over the period 2000 to 2018. The strong and weak sustainability theories were used as a framework to analyze this paper. The panel data approach was used, and fixed and random effect models were used. The results obtained show that energy consumption and CO2 emissions have a non-linear relationship, justifying the existence of an inflection point. These results suggest that, due to a certain level of energy consumption and CO2 emissions of concern, African countries modify their consumption trajectory by adopting much cleaner energies and by boosting cooperation in environmental preservation.
