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 distribution-loss factor for purchased district heat and steam. Report it separately from the corresponding Scope 2 heat or steam factor; do not add it when the purchased-energy factor already includes distribution losses.
