Calculate flight emissions per passenger including altitude effects.
Short flights emit more per kilometre because take-off and climb consume a large share of the fuel regardless of distance. Cabin class matters because premium seats occupy more floor area per passenger. Flying is usually the single largest discretionary component of a personal footprint, so one long haul return trip can outweigh a year of other choices.
