Abstract
The assimilative capacity is defined as the capacity of an environment to receive a given level of emissions, degrading or dispersing them and converting them in harmless substances to humans or ecosystems. In the case of urban air pollution, it is mainly driven by the meteorological factors that govern air mixing and dispersion of the pollutants. Due to the large temporal variation of these factors, there is a strong diurnal variation in the assimilative capacity, in addition to the diurnal variation in hourly traffic flows and vehicular emissions. In this paper we investigate the effects of the temporal variation of the assimilative capacity on pollution concentration and illustrate the need for temporally differentiated road pricing through an application to the case of the congestion charge in Stockholm, Sweden.
By accounting explicitly for the role of the assimilative capacity on optimal road pricing, we allow for a more comprehensive view of the economy-ecology interactions at stake, showing that price differentiation is an optimal response to the physical environment; higher fees at a certain time of the day are optimal since they discourage traffic when the assimilate capacity is constrained. Moreover, our results are of practical relevance since most congestion charges in place do resemble variable price schemes to some extent as they incorporate price bans to mitigate congestion. Our analysis indicates that such price variations should also be a response to limited air mixing resulting in reduced assimilative capacity.
