Hello, I have some doubts about the new pack of methods nexus impact ecoinvent v2.2.
I want to use the methodology impact 2002+, I can see all characterization factors are included, but not sure if further includes normalization and weighting.
greetings to all the team!
normalisation and weightings nexus pack impact method
Re: normalisation and weightings nexus pack impact method
Hi, the LCIA ecoinvent 2.2 methods are provided by the ecoinvent centre in EcoSpold 1 format, which does not support normalisation and weighting. We provide a separate LCIA method pack as openLCA database, which includes normalisation and weighting as separate values. These are available on the openLCA download page, for free.
Best wishes,
Andreas

Re: normalisation and weightings nexus pack impact method
I see, but as I was trying to express, ecoinvent does not provide the normalisation values and these are the original methods from ecoinvent with only the flows adapted. Our "own" method pack contains the normalisation values (available on the openLCA download page).

Re: normalisation and weightings nexus pack impact method
Hi,
Perhaps this was already clear to everyone, but yes, the results expressed in "points" were normalized (before importation in openLCA, this is more a matter of how ecoinvent distributes CFs, not an openLCA issue.
If you would like a file to convert results back to un-normalized endpoints or midpoints, let me know, I can send one.
