Each point is one activity: what ecoinvent 3.8 cut-off published for pesticides into soil (UBP), against what VoLCA computes from the same EcoSpold 2 source under the publisher's own ecological scarcity 2013 factors. The black line is equality and the grey band is 1%. 18,273 activities were compared; 2,472 fall outside the band, more than a picture can hold, so 1,828 of the 18,273 are drawn, evenly spaced over the published value whichever side of the band they fall, and the 177 of the 200 farthest from equality that this walk missed are added. Where several fall on one spot, at most three markers are drawn there, since a fourth would not darken it. Median ratio 0.9935, 13.53% outside the band. This misses the agreement a release is held to: at most 5% of activities outside the band and a median ratio inside it.
