1 Weighting factors have not been established worldwide; the European weighting factors are recommended for impact potentials located outside Europe or at unknown locality

2 Weighting factors have only been established for human toxicity via soil for

Europe, because there are no Danish reduction targets; the European weighting factor is recommended as default value for impact potentials located in Denmark.
