Dear openLCA team,
I recently downloaded the new methods (2.0.4) and tried out the updated EF method (adapted) with OpenLCA 1.9 and Ecoinvent 3.5.
After comparing it with the impact method set I used before (ILCD 2.0 2018 midpoint) I am shocked about the differences in 'land use'. While all the other impact categories show very similar results (plusminus a few percent), land use differs drastically.
For example the two following Ecoinvent 3.5 datasets:
Extrusion, plastic film
ILCD 2.0 2018: 19.92762 Pt
EF method: 0.38889 Pt
Kraft paper production, bleached
ILCD 2.0 2018: 525.79875 Pt
EF method: 2.04827 Pt
Do you have any idea about the reasons of these dramatic differences?
