In Figure 4.5 REQ normalised results of considered impact categories are
represented.
The highest normalised indicator results for Germany occur for impact
categories fossil resource demand, greenhouse effect and land use. There is
a particularly large margin with regard to the remaining impact categories.
Taken by themselves the normalised results suggest that the results of
scenarios with respect to the impact categories fossil resources demand,
greenhouse effect and natural utilisation of space should be adequately
considered within an interpretation of the results. A special relevance of
these categories for a comparison of scenarios is also owing to large
absolute differences in REQs.

Weighting

‘Weighting’ for LCAs including comparative assertions to be disclosed to the
public is not permissible in accordance with ISO 14040/44 and therefore not
included in this study.
