In this paper, I investigate how much individuals living in the Paris area are exposed to local air pollution and how much they contribute to transport-related air pollutant and CO2 emissions. I examine the specific role of income in determining exposure and emissions, leveraging detailed geocoded income, transport and pollution data. I find that exposure to pollution follows a U-shaped curve as a function of income when measured at the place of residence, but tends to be higher for richer households when daily mobility is taken into account. I also find substantial within-decile heterogeneity related to differences in spatial and other socio-economic characteristics. In contrast, travel-related emissions tend to unequivocally increase with income. I discuss the implications for the distributional impacts and political economy issues associated with the planned low emission zone (LEZ) in Paris, in a context where the decision to join the LEZ rests upon municipalities.
