Summary

Story summary

Many flight carbon footprint calculators provide inconsistent estimates due to oversimplified assumptions.
They often omit carbon dioxide equivalent emissions and non-CO2 impacts such as nitrogen oxides and contrails.
Calculators may not reflect actual flight paths, leading to underestimations of fuel use and emissions.
A comprehensive calculator should include all emissions sources, align with ISO 14083 standards, and clearly communicate its methods.
