I have conducted an LCA in ReCiPe 2016 and have my midpoints on a graph. How do I evaluate the magnitude of my results? I can tell which outcomes are relative to one another - sure - but I want to put the scale of this assessment in context. Is a midpoint normalization score of 0.1 bad? what about 0.5?

Please link me to documentation that guides this - I cannot find it in the ReCiPe publications.

Thanks!

Typically the reference value is quite low meaning a normalised value of 0.5 is quite high, but you can of course select different normalisation values, which can also be smaller. The main purpose of normalisation is to make the impact category results for one study and calculation comparable, removing also different units. And for single score methods, to prepare results for weighting.

Best wishes,
