I would like to know the reason behind the large difference I noticed between the result obtained from OpenLCA EF2 database and what results from Look@LCI with EF2. The only difference is for the LandUse category.

The process used is modelled following the indications from your manual.

Thank you,

I already reported that it is not the land use method is not working properly here:


Sadly to no avail

Thank you for the answer but I believe is something different since I am talking about the EF database, (https://nexus.openlca.org/database/Environmental%20Footprints) which should make use of different elementary flows.

Dear Nicola,

Please let us know which process exactly you are using to obtain these results, so we can try to reproduce the results and have a look

The process  is: "Electricity grid mix 1kV-60kV, consumption mix, to consumer, AC, technology mix, 1kV - 60kV "
I have found that the method implemented in OpenLCA has multiple non-regionalized flows for land use (I have mostly found 3 duplicated flows with different CFs), and only 1  has the same CF found in the JRC node. Maybe could be related to that.
