currently I try to teach myself how to conduct an LCA with OpenLCA. I downloaded the software and started with an online tutorial how to implement databases and LCIA.
I downloaded three different databases:
(1) elcd_3_2_greendelta_v2_18 (downloaded from https://nexus.openlca.org/databases
I can open processes and there are results for Impact analyses. However, data is limited so I was looking for further databases.
(2) NREL (downloaded from https://www.lcacommons.gov/
There are many different processes and Inputs and Outputs are listed. However, Impact Analyses are empty, regardless of the LCIA I select (I believe). Why?
(3) EPA (downloaded from https://www.lcacommons.gov/
There are many different processes and Inputs and Outputs are listed. Unit of Inputs and most Outputs is USD(?). I don't know how to interpret this?
Sorry if those questions are dumb...I am still in my beginnings. Do you have any recommendations for a good case study that can be conducted with a database free of charge?
Best regards and thanks :-)
