ecoinvent 3.10.1 cut-off, climate change: fossil, including SLCFs / global warming potential (GWP100)

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 3.10.1 cut-off, climate change: fossil, including SLCFs / global warming potential (GWP100)
Each point is one activity: what ecoinvent 3.10.1 cut-off published for climate change: fossil, including SLCFs / global warming potential (GWP100) (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%. 17,972 activities were compared; 13,591 fall outside the band, more than a picture can hold, so 1,997 of the 17,972 are drawn, evenly spaced over the published value whichever side of the band they fall, and the 172 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 1.0326, 75.62% 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.
