-According to the method applied, 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  alculation, but the effect has not yet been quantified.+AD is a result of multiplying the number of houses constructed and a conversion factor.
