This paper examines the redistributive effects of taxing carbon dioxide emissions on household welfare through changes in prices of consumer goods. To this end, the results of a computable general equilibrium model are sequentially integrated with a household-level analysis based on microsimulation models (MSM). The analysis also allows for comparisons between the effects of using arithmetic and behavioral MSMs. Results show that a carbon tax has negative effects on population welfare, with higher-income households being the most affected and middle-class households the least. Finally, a number of policy recommendations for reducing emissions and including well-being criteria in mitigation measures are presented.
