ABSTRACT The present paper introduces informality into the climate change-poverty nexus using 40 Sub-Saharan African countries selected from high-, middle and low-income countries between 1990 and 2019. The empirical results show that informality is an important variable that can mitigate the impact of climate change on poverty. The moderation of the poverty-climate change nexus is nonlinear in income. Informality reduces the negative effect of climate change on poverty in middle income countries while exacerbating its effect in low-income countries. Possible channels of influence are identified. Policy makers need to rethink the role of informality in an environment where informality is mainly seen as a nuisance, to see it as an ally that can achieve key results for the fight against environmental degradation and extreme poverty.
