Work out a flight's emissions

5,540 km each way · Long-haul from the UK · 11,080 passenger-km

1.69 t CO2e with the radiative forcing uplift

1.00 t CO2e without it (0.1528 and 0.0904 kg CO2e per passenger-km)

2026 government flight factors (DESNZ), applied to the great-circle distance: they already include DESNZ's 8% uplift for indirect routes and delays. Radiative forcing counts the extra warming from emissions at altitude; the government recommends including it. Business travel is Scope 3, category 6.
