This comparative study covering 41 countries explores whether the distribution of national carbon emissions shapes the public willingness to pay higher environmental taxes and if this relationship is moderated by the quality of government. Using multilevel regression models, it draws on data from all four waves of the International Social Survey Programme’s Environment modules (1993–2020), combined with carbon emissions data from the World Inequality Database. Cross-sectional and longitudinal results suggest that the public willingness to pay additional taxes is lower in contexts where the non-rich are responsible for a larger or increasing share of national carbon emissions, particularly in contexts with low or declining quality of government. It is concluded that the distribution of emissions may impact public support for environmental taxes, but that well-functioning government institutions can mitigate negative public backlash linked to the often-perceived regressive character of these taxes.
