Problem with results in Impact assessment method "ecoinvent - EF 3.1 v"

Question

I encountered problems with the results of the Impact assessment method

 "ecoinvent -  EF 3.1 v"

This method provides results for 16  different impact categories.

For two of these, specifically, water use (m^3 depriveded) and energy resources (abiotic depletion potential in MJ), I get null values.

Where could the problem come from?

thank you all in advance for your help.

Answer 1

Maybe you imported the method into a different database and not all elementary flows (UUID numbers) of that new database are compatible, so that not alle elementary flows that are inside the characterization factors tables will be same as the ones used in processes?

Usually the ecoinvent implementation of impact methods (for example ecoinvent - EF v3.1) are only meant to be used inside the corresponding ecoinvent databases. In Nexus we put the right versions of impact methods directly into the ecoinvent databases. The stand-alone ecoinvent methods are only offered in Nexus as a kind of "documentation" or if users want to use them for specific own mappings/projects.
