Methodology
Derived from direct physical activity measurements (litres, kilometres, kilograms). The most accurate approach where activity data exists.
Notes
* Scope 3 boundary · This Scope 3 Category 3 well-to-tank factor covers upstream fuel-supply emissions associated with purchased heat or steam. Report it separately from the corresponding Scope 2 heat or steam factor; distribution losses and their upstream component are separate records.
