The unit of the normalised results is in all cases "Person Equivalents" (PE), see 3.4. Negative values indicate a benefit resulting from the treatment method following discarding by the first user, while a positive value indicates an (unwanted) impact of the treatment method. The main aim of the figures is to provide an easier overview than that found in the tables, nut it is underlined that only the tables present the full overview as defined in ILCD.
