Each point is one activity: what ecoinvent 3.11 cut-off published for land use (dimensionless), against what VoLCA computes from the same EcoSpold 2 source under the publisher's own EF v3.1 factors. The black line is equality and the grey band is 1%. 23,586 activities were compared; 1,965 from inside the band are drawn, evenly spaced over the published value, plus the 16 outside it. Where several fall on one spot, at most three markers are drawn there, since a fourth would not darken it. Median ratio 1.0000, 0.07% outside the band. This meets the agreement a release is held to: at most 5% of activities outside the band and a median ratio inside it.
