A weighting factor proposed in this paper is a product of a reduction factor (Ni/Ti) and a relative significance factor (fi). A politically determined critical impact (Ti/fi) is assumed to cause a critical damage defined as a level of damage acceptable to a society. A graph showing the relationship between relative damage and normalized impact indicates that the weighting factor ((Ni/Ti) fi) is the slope of this graph. It shows further that the relative damage is the same as the weighted impact.
