-For particulate emissions, Construction is the second main emissions source in the Mineral industries.+Regarding particle emissions, construction is the second-largest emissions source within NFR 2.A - Mineral industries.
  
 ===== Methodology ===== ===== Methodology =====
  
-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) [(Umweltbundesamt, 2016: Development of Methods for the Generation of Emission Data for Air Pollutants from Building Activity and Construction Zones, Dessau-Roßlau, 2016 FILE?)], 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 EMEP/EEA air pollutant emission inventory guidebook, a tier1 method is applied to estimate particulate matter emissions.  
 +However, this tier1 method is applied with various adaptations to national conditions improving it to a rather higher tier, perhaps T1/T2. 
 + 
 +The approach for uncontrolled fugitive emissions from 2.A.5.b was adapted for national circumstances within a research project by Kampffmeyer & Visschedijk (2016) [(KAMPFFMEYER2016)], partly considering existing emission-control technologies. As a result, statistical information is combined with modified default emission factors for TSP and PM.
  
 ==== Activity data ==== ==== Activity data ====
  
-Activity data are determined taking into account figures for various construction activities. Data is based on production statistics (national statistics). According to the method used, figures of area of land affected by construction activities per building were concluded from statistical data and multiplied with emission factors, as explained below. The common uncertainty of 3% for national statistics could be increased as a result of this  calculation, but the effect is not estimated at the moment.+Activity data are determined taking into account figures for various construction activities and based on national production statistics.

 +AD is a result of multiplying the number of houses constructed and a conversion factor.

 //**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.
