Cost of air pollution from motorized two-wheelers in Paris

Exposure to air pollution is a major cause of mortality worldwide, including in Europe, with transportation emissions being a primary contributor to urban air pollution. This article employs the impact pathway approach to quantify the monetary value of the adverse health effects of motorized two-wheelers on Parisian residents. Key pollutants are identified, and motorized two-wheelers' circulation data in Paris is spatially, temporally, and technologically disaggregated to prepare it for input into the HYSPLIT dispersion model. The total health cost borne by Paris residents due to air pollution from motorized two-wheelers in the city is estimated to be approximately €12 million per year as of 2020, representing 0.34% of the total health cost of air pollution in Paris. This relatively modest figure suggests that the majority of the adverse health effects associated with motorized two-wheelers are experienced not by Paris residents but by those in the surrounding areas.
