Each point is one activity: what BAFU 2025 v1 published for Carcinogenic 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%. 11,551 activities were compared; 1,920 from inside the band are drawn, evenly spaced over the published value, plus the 35 outside it. Where several fall on one spot, at most three markers are drawn there, since a fourth would not darken it. Median ratio 0.9999, 0.30% 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.
