getting zero values for all impact categories when using NREL USLCI

Question

I keep getting zero values for ALL lifecycle impact results when using NREL USLCI database. I'm using openLCA 2.4. I downloaded USLCI database (.zolca) from NREL github repository. This didn't seem to work so I also downloaded and imported impact assessment methods separately (e.g. https://catalog.data.gov/dataset/recipe2016v1-1-for-fedeflv1). I tested both for recipe and traci methods. But none of these worked. I've included some screenshots. 

I do not have any of these with ecoinvent database I'm using with openLCA. I'd appreciate some insights!

Answer 1

Hi, the USLCI database from LCACommons does not fit to our reference flows and thus to our LCIA methods, therefore you are not getting results.  We are providing a version which is mapped to our flows, on Nexus. I think LCACommons also provides an own LCIA method, this could work for you too.

Answer 2

You can either use GreenDelta's version on the Nexus along with the Nexus LCIA method pack, or you can download data from the Federal LCA Commons (lcacommons.gov) and use the LCIA methods found there, but you can not mix and match like Andreas said.
