Air travel emission factors
Passenger travel by air. From 10 libraries, filed in one model so one publisher's factor compares with another's.
What the 8 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.
