Agribalyse 3.1.1, Climate change
Each point is one activity: what Agribalyse 3.1.1 published for Climate change (), against what VoLCA computes from the same SimaPro CSV source under the publisher's own EF 3.1 adapted 1.0 factors. The black line is equality and the grey band is 1%. 2,488 activities were compared; 838 fall outside the band, more than a picture can hold, so 1,244 of the 2,488 are drawn, evenly spaced over the published value whichever side of the band they fall, and the 107 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 0.9936, 33.68% 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.
