BAFU 2026 v1, Radioactive substances into air
Each point is one activity: what BAFU 2026 v1 published for Radioactive substances into air (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%. 11,651 activities were compared; 8,829 fall outside the band, more than a picture can hold, so 1,942 of the 11,651 are drawn, evenly spaced over the published value whichever side of the band they fall, and the 163 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 1.0312, 75.78% 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.
