This paper examines the dynamic relationship between financial development, income inequality and carbon dioxide (CO2) emissions in a step-wise fashion, using data from 39 sub-Saharan African (SSA) countries during the period 2004–2014. The study uses three income inequality indicators – the Gini coefficient, the Atkinson index and the Palma ratio – to examine these linkages. The study employs the generalised method of moments as the estimation technique. The empirical findings show that financial development unconditionally reduces CO2 emissions in SSA countries. The findings also show that there are threshold levels of income inequality that should not be exceeded in order for the negative impact of financial development on CO2 emissions to be sustained. Specifically, the study finds that the negative impact of financial development on CO2 emissions is likely to change to positive if the following inequality levels are exceeded: 0.591, 0.662 and 5.59, respectively, for the Gini coefficient, the Atkinson index and the Palma ratio. The findings of this study have far-reaching policy implications not only for SSA countries but also for developing countries as a whole. Policy implications are discussed.
