BAFU 2025 v1, Energy resources
Each point is one activity: what BAFU 2025 v1 published for Energy resources (UBP), against what VoLCA computes from the same EcoSpold 1 source under the publisher's own Ecological Scarcity 2021 factors. The black line is equality and the grey band is 1%. 11,579 activities were compared; 3,972 fall outside the band, more than a picture can hold, so 1,930 of the 11,579 are drawn, evenly spaced over the published value whichever side of the band they fall, and the 164 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 1.0059, 34.30% 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.
