This work presents two emission scenarios for PM10 emissions in Lombardy region, based on the results of emission inventory for the year 2008, the analysis of emission factors for different appliances, information about the type and number of appliances sold and considering the effect of different policies. The scenario implemented takes into account the natural trend of appliance renewal as well as technological improvements. New policies for emission reduction are considered, such as informative campaigns and the implementation of legislative actions. In the ‘business as usual scenario' biomass consumption increases 30% from 2008 to 2020 because of a major use of pellets, since wood consumption is decreasing by 23%. In the meantime, PM10 emissions decrease by 33% due to the lower specific emissions of new appliances. Among the policies studied, the ban of less efficient burners is the most effective measure, with a 18% potential reduction; the same potential is obtained combining the regulation of maintenance with an intensive information campaign. The introduction of compulsory standards for appliances sold after 2015, following the model of the German legislation, is associated with the most rapid decrease in emissions; nevertheless benefits would be mainly concentrated after 2020. ; SeriesInformation ; Proceedings of the 20th European Biomass Conference and Exhibition, 18-22 June 2012, Milan, Italy, pp. 2268-2273
