Methodology
Derived from direct physical activity measurements (litres, kilometres, kilograms). The most accurate approach where activity data exists.
Notes
* Scope 3 boundary · This is a Scope 3 Category 3 transmission-and-distribution loss factor for purchased UK electricity. Report it separately from the corresponding Scope 2 electricity-generation factor; do not add it when the electricity factor already includes grid losses.
