New evidence for 21 OECD countries shows that the distributional effects of energy taxes differ by energy carrier. On an expenditure basis, taxes on transport fuels are not regressive on average, as households in lower expenditure deciles spend a lower proportion of their expenditure on taxes on transport fuels. While the unweighted 21-country average of the proportion of income spent on transport fuel taxes is highest for households in the lowest and in the middle deciles, there is heterogeneity across countries. Some countries show progressive effects of taxes on transport fuels both on an expenditure and an income basis, while others show more proportional effects or tend to place the highest burden on middle expenditure deciles. Taxes on heating fuels are slightly regressive, i.e., the percentage of expenditure spent on them decreases with expenditure. Taxes on electricity are more regressive than taxes on heating fuels.
