Each point is one activity: what ecoinvent 3.10.1 cut-off published for photochemical oxidant formation: human health (kg NMVOC-Eq), 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%. 21,759 activities were compared; 1,979 from inside the band are drawn, evenly spaced over the published value. Where several fall on one spot, at most three markers are drawn there, since a fourth would not darken it. Median ratio 1.0000, 0.00% 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.
