DEFRA 2026, Small car (Plug-in Hybrid Electric Vehicle) — electricity T&D losses, Factors by Category sheet, ID 14_301_3051_4_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 the Scope 3 Category 3 transmission-and-distribution loss component of EV charging, not the vehicle’s complete journey footprint. Use it alongside the matching Scope 2 UK electricity-for-EVs factor when the charging electricity is inside the reporting boundary; do not add it when grid losses are already included. Petrol or diesel combustion by a PHEV is not included.
