DEFRA 2025, Long-haul flight — Premium economy class, Factors by Category sheet, ID 21_316_3172_11_1
Derived from direct physical activity measurements (litres, kilometres, kilograms). The most accurate approach where activity data exists.
Radiative forcing (RF) · With RF estimates aviation’s broader climate impact by applying DEFRA’s 1.7 central multiplier to the direct CO₂ component for effects such as contrails, water vapour and nitrogen oxides. Without RF includes direct CO₂, CH₄ and N₂O only. Both choices already include DEFRA’s 8% route-distance uplift. Choose one option, never add them together. Use With RF for a broader climate-impact estimate; use Without RF when a reporting method specifically requires direct greenhouse gases only or for consistency with an established base year.
* Scope 3 boundary · Use this factor for Scope 3 Category 6 passenger flights undertaken for business in aircraft outside the reporting organisation’s ownership or control. Multiply passenger-kilometres by the factor matching the flight type and cabin class. The matching well-to-tank factor is a separate Scope 3 Category 6 upstream-fuel component.
