BAFU 2025 v1, Heavy metals into water
Each point is one activity: what BAFU 2025 v1 published for Heavy metals into water (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%. 11,549 activities were compared; 1,906 from inside the band are drawn, evenly spaced over the published value, plus the 115 outside it. Where several fall on one spot, at most three markers are drawn there, since a fourth would not darken it. Median ratio 1.0002, 1.00% 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.
