Water supply emission factors
Mains water supply and its treatment for delivery. From 8 libraries, filed in one model so one publisher's factor compares with another's.
What the 7 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.
