How does the GHG Protocol define short, medium and long haul flights?

Question

Accepted Answer

The Greenhouse Gas (GHG) Protocol's business travel guidance gives an indicative split: short haul is a flight under 3 hours, medium haul 3 to 6 hours, and long haul usually over 6.5 hours by wide-bodied aircraft. Short flights carry higher factors per kilometre because take-off and landing weigh heavily. Short haul: flights under 3 hours. Medium haul: flights of 3 to 6 hours. Long haul: journeys by wide-bodied aircraft over long distances, typically more than 6.5 hours. The guide says short flights have higher factors per passenger-kilometre because the landing and take-off cycle has a strong influence on emissions. Long flights come out slightly higher than medium ones because of the extra weight of fuel. It calls these descriptions indicative and notes that many countries define flight types in their own way. Sort each trip by time in the air, then use the factor for that band with the distance flown. If your factor source defines its bands by distance instead, use its definition with its factor and write down which one you used. If you add a radiative forcing multiplier, the guide says to disclose the factor.
