This paper addresses the question of the distributional burden of a carbon tax. It shows that, not only the income measure -- annual or lifetime -- matters for the incidence of the tax, but also the underlying distribution of income. The Swedish carbon tax on transport fuel is regressive between 1999-2012 when measured against annual income, but progressive when using lifetime income. The overall trend, however, is toward an increase in regressivity, which is highly correlated with a rise in income inequality. Analysis of the determinants of distributional effects lends support to our hypothesis that, for necessities -- goods with an income elasticity below one -- rising income inequality increases the regressivity of a consumption tax. To mitigate climate change, a carbon tax should be applied to goods that typically are necessities: transport fuel, food, heating, and electricity. Carbon taxation will thus likely be regressive in high-income countries, the more so the more unequal the distribution of income.
