-Since the last update of the UNECE Guidebook we use the Tier 1 method to estimate the national emissions of particulate matters. The approach for uncontrolled fugitive emissions for this source category was adapted for national circumstances within a research Project (Umweltbundesamt, 2016) [((bibcite 1))], partly considered exiting control techniques. As a result, the information of the statistics is combined with modified default emission factors for TSP and PM.+Since the last update of the UNECE Guidebook we use the Tier 1 method to estimate the national emissions of particulate matters.

 //**Why do German EFs differ from EEA defaults?**// - It has to do with the default 50% reduction for non-residential buildings and roads (as a result of wetting unpaved temporary roads) that is assumed in the calculations for Germany. This is also already accounted for in the EPA emission factors. It is a result of a control measure that is nearly always taken but in principle optional. In the Guidebook a 50% reduction is advised. //**Why do German EFs differ from EEA defaults?**// - It has to do with the default 50% reduction for non-residential buildings and roads (as a result of wetting unpaved temporary roads) that is assumed in the calculations for Germany.
