How Travel Emissions Are Estimated
Travel emissions are estimated using widely accepted emissions factors that account for distance traveled, transportation type, and typical fuel use. For flights, estimates consider factors such as route distance, aircraft efficiency averages, and seat class assumptions rather than exact aircraft or load data.
Because real-world conditions vary, these calculations are intended to provide directional insight, not precise measurements. The goal is to help you understand the relative impact of different travel choices and identify opportunities to reduce or offset emissions responsibly.
Why Different Flights Have Different Impacts
Not all flights produce the same level of emissions, even when traveling similar distances. Factors such as flight length, aircraft type, seating configuration, and whether a flight is direct or includes layovers can significantly affect per-passenger emissions.
Shorter flights tend to have higher emissions per mile due to fuel-intensive takeoff and landing phases, while long-haul flights often distribute emissions more efficiently across distance. These differences are why two trips to the same destination can have meaningfully different carbon footprints.
