In view of the challenges posed by climate change and the increasingly ambitious climate targets around the world, the search
for effective climate policy instruments is gaining momentum. Carbon pricing, for example, in the form of a carbon tax, and
its effects are therefore attracting increasing attention in academic as well as policy discussions. We review the empirical
effects of carbon taxes with regard to several impact dimensions commonly studied in the literature: environmental effectiveness,
macroeconomic effects, impacts on competitiveness and innovation, distributional implications, and public acceptance. An increasing
body of empirical studies shows that carbon taxes can effectively reduce carbon emissions or at least dampen their growth
while not negatively affecting economic growth, employment, and competitiveness. The existing empirical evidence suggests
that the distributional impact of carbon taxes depends on the type of energy use and the indicators to capture distributional
effects, as well as on household characteristics. Lump-sum transfers are shown to be better suited to mitigate regressive
effects for lower incomes, while higher incomes benefit more from a reduction of labour taxes. Public acceptance of carbon
taxes can be increased by providing public information, avoiding negative distributional effects, and channelling part of
the revenues into "environmental projects".
