I found TRACI, which works for the a lot of processes in the LCA Commons database.
When I download additional processes from the Commons database they appear to be unlinked to TRACI. If I understand correctly it is because they use different flows then the ones linked to TRACI. That is, the 'carbon dioxide' linked to TRACI is different from the 'carbon dioxide' flow utilized by other impact assessment methods. In order to return results in TRACI I have been replacing one 'carbon dioxide' with the other.
I hope that makes sense. I am still new to OpenLCA and its terminology.
