What the 6 factor pages say

One chart per unit, since a kilogram and a kWh do not compare. Colour is the boundary, what the factor counts; every row also names it.

Per kg · 4 factor pages

Linear scale, from 10.8
From 10.8 (Hydrogen, EU CBAM) to 11.1 (Hydrogen produced on site - natural gas steam reforming, ADEME) kgCO₂e per kg. 2 boundaries appear here, so part of the spread is what each factor counts, not a disagreement between publishers.

Per kWh · 2 factor pages

Linear scale, from -1
From 0 (Other non-fossil fuels - Hydrogen, Statistics Finland) to 0 (Hydrogen, RVO) kgCO₂e per kWh.
