Notes
* Scope 3 boundary · Use this factor for Scope 3 Category 6 passenger road journeys undertaken for business in vehicles outside the reporting organisation’s ownership or control. Choose the car, motorbike, bus, coach, or taxi record and unit that match the travel data available. Separate factors apply to employee commuting, owned or controlled vehicles, freight transport, rail travel, and upstream well-to-tank emissions.
