DEFRA 2026, 5% loss (kWh) — district heat and steam distribution losses, Factors by Category sheet, ID 13_403_4004_5_1
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.
