Factors are well-to-wheel CO₂e (fuel production + combustion), based on UK DESNZ/DEFRA 2024 conversion factors and EEA averages; bus, coach and ferry assume average occupancy.
Cars: fuel consumption × 2.69 kg/L petrol, 3.13 kg/L diesel. EVs: kWh × 1.10 charging losses × 251 g/kWh (Romania average). Car emissions are divided among the travellers.
Flights: per-passenger-km factor for the distance band × 1.08 routing uplift, including non-CO₂ effects (radiative forcing ×1.7). Short flights burn proportionally more fuel at take-off.
