Hi Anne, there are no public explanations so far but it is relatively easy to try out; you can change amounts of exchanges in input / output easily, if you add flows, these need to be also in the "flows" sheet and also in the flow property factor sheet. You should not delete the other sheets as they...

Hello Amy, welcome and: yes, I think this is unfortunately a common topic. The ecoinvent methods that we distribute are directly from ecoinvent; some time ago we have started to develop an own LCIA method pack, reflecting other databases and thereby also other elementary flows, in part, but also to ...

@OFENTSE MOSEKI : well I think this is a different problem (unintuitve "side" of the flow, input instead of output), which happens in some databases due to waste modeling e.g. (and is even less intuitive when negative amounts are applied to preserve the mass balance) @lbhsa: Yes of course that is po...

For some databases, like ecoinvent or Agri-footprint, we are providing the LCIA methods in the database therefore the import is ...

Hello and welcome,

Hi Jasmin,
sometimes the JDK isn't used on a Mac but the default Java installation which is still 1.6 I believe. You can test this by entering "java -version" on the command line. See also other posts about this issue for Mac on this forum.

That approach works but you need to fully reflect the JSON-LD structure, e.g. the line breaks should be removed (but I am not certain if they are only added here in the code window).

Yes indeed, the impact analysis (!)

Hello Pam,
welcome - basically you need to double-click on the box to make it expand and show the products.
Hope this helps,
