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.
