Abstract. Air quality modeling associated with emission scenarios has become an
important tool for air quality management. The set-up of realistic emission
scenarios requires accurate emission inventories including the whole
methodology used to calculate the emissions. This means a good description
of the source characteristics including a detailed composition of the
emitted fluxes. Two main approaches are used. The so-called bottom-up
approach that relies on the modification of the characteristics of the
sources and the top-down approach whose goal is generally to reach standard
pollutant concentration levels. This paper is aimed at providing a general
methodology for the elaboration of such emission scenarios and giving
examples of applications at local and regional scales for air quality
management. The first example concerns the impact of the installation of the
urban tramway in place of the road traffic in the old centre of Strasbourg.
The second example deals with the use of oxygenated and reformulated car
fuels on local (Strasbourg urban area) and regional (upper Rhine valley)
scales. Finally, we analyze in detail the impacts of the incoming European
emission regulation for 2015 on the air quality of the upper Rhine valley.
