The company had previously reported emissions in kilograms of “carbon dioxide equivalent” , a measure that includes the damage to the climate from other aviation emissions, such as water vapour emitted at high altitudes as part of the plane’s contrails, which can have a significantly higher warming effect per tonne than pure COemitted on each journey, effectively halving the stated environmental impact of any given flight.
