I have recently updated OpenLCA. I have downloaded the most recent zolca file for the US LCI database from the USLCI website, not directly from OpenLCA. When I run a process, I get an inventory but all 0 for impact assessment. I tried ILCD and TRACI.

The USLCI does not come pre-loaded with impact assessment, and because it uses the Federal Elementary Flow List, any impact assessment method must also be compatible with that flow list.

You can find information on how to obtain TRACI and ReCiPe for use with the USLCI here:


More impact methods will be available soon.
