ecoinvent 3.12 cut-off, climate change: aircraft emissions

A comparison of published impact results with VoLCA calculations from the same source data and the publisher’s impact factors. Points on the diagonal agree.

ecoinvent 3.12 cut-off, climate change: aircraft emissions
Each point is one activity: what ecoinvent 3.12 cut-off published for climate change: aircraft emissions (kg CO2-Eq), against what VoLCA computes from the same EcoSpold 2 source under the publisher's own IPCC 2021 factors. The black line is equality and the grey band is 1%. 20,210 activities were compared; 20,210 fall outside the band, more than a picture can hold, so 1,838 of the 20,210 are drawn, evenly spaced over the published value whichever side of the band they fall, and the 181 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 161588039.4957, 100.00% 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.
