AERIS are to be quantified with the Spain's Emission Projection (SEP) model (Lumbreras et al., 2008). These projections were estimated for each of the pollutants mentioned above, considering only a situation de- fined by the current legislation (CLE) in order to analyse the effective- ness of the implemented plans, measures and policies in Spain. Additional considerations regarding the nature and potential evolution of the macroeconomic drivers of the projections, specifically those concerning the latest economic crisis in southern Europe were imple- mented according to what has been published in MARM (2009) and Torrero (2010). The aggregated national emissions (without SNAP sec- tor distinction) of the studied pollutants across the studied years are presented in Table 1 and Fig. 1.
