The poverty and distributional impacts of carbon pricing on households: evidence from Ghana, Nigeria and Uganda

Abstract We examine the distributional impact of domestic carbon pricing in three Sub-Saharan African countries. We combine household expenditure surveys and sectoral carbon intensity data derived from a multi-regional input-output model for Ghana, Nigeria and Uganda. Our findings indicate that domestic carbon pricing is progressive in all three countries. This primarily results from higher budget allocations for direct energy consumption in wealthier households, especially concerning motor vehicles and electrical appliances. Disparities in welfare losses within income groups are primarily due to varying energy consumption patterns. Importantly, we identify low-income households as being disproportionately affected by carbon taxes. Lump-sum transfers could fully compensate most households in the bottom two income quintiles, significantly reducing poverty. Our comparative analysis emphasizes the importance of country-specific differences in energy expenditures and carbon intensities in shaping the distributional outcomes of carbon taxes.
