Notes

* Scope 3 boundary · This is a Scope 3 Category 3 well-to-tank factor for emissions from producing and delivering the fuel before it is used. When the reporting organisation burns the fuel in equipment or vehicles it owns or controls, report this separately from the corresponding Scope 1 combustion factor; it does not replace or include combustion emissions.
