Each point is one activity: what ecoinvent 3.10 cut-off published for human toxicity: non-carcinogenic, organics (CTUh), 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%. 21,771 activities were compared; 1,976 from inside the band are drawn, evenly spaced over the published value, plus the 43 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, 0.20% 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.
