BAFU 2025 v2, Climate change
Each point is one activity: what BAFU 2025 v2 published for Climate change (kg CO2 eq), against what VoLCA computes from the same EcoSpold 1 source under the publisher's own EF 3.1 adapted 1.05 factors. The black line is equality and the grey band is 1%. 11,556 activities were compared; 1,926 from inside the band are drawn, evenly spaced over the published value. Where several fall on one spot, at most three markers are drawn there, since a fourth would not darken it. Median ratio 1.0000, 0.00% 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.
