Incremental Selection of Regional Air Quality Measures

Abstract To comply with EU regulations, local environmental authorities of the regions where the mandatory air quality limits are not met must develop suitable emission reduction plans. These normally represent a compromise among what is economically feasible, what is politically acceptable, and what can provide measurable benefits. As a consequence, they include a large number of different abatement measures pertaining to a wide variety of fields (transport, building, agriculture…), the total effect of which is different from the simple sum of the individual outcome. We illustrate how such a problem has been tackled in an Italian region, supporting the analysis through an integrated modelling tool.
