-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.

 +\\ 
 +- pollutant-specific emission factor, not corrected for soil moisture and silt content (kg of emitted pollutants/m² affected area/year), 
 +\\ 
 +- average affected area as product of number of buildings constructed multiplied with conversion factor (average affected area per building), 
 +\\ 
 +- duration of construction activity from default values (EMEP/EEA, 2023)[(EMEPEEA2023)],

-The EF is adapted with Moisture Level Correction factor and Silt Content Correction factor in all cases, both 0.20 and 2.22. The assumption about the duration of the construction activity uses the Default values (EEA, 2023)[(EEA2023)]: 
-^ Type of building                                   ^^  Estimated duration (year)      ^^ 
-| Construction of houses (single and two family)     ||  0.5 (6 months)                 ||
