Reducing aviation’s climate impact requires more than calling a flight carbon neutral. Aircraft can burn less fuel, use lower-lifecycle-carbon fuels and operate more efficiently. These measures address different parts of the problem and should be assessed separately from any offset claim.

Aircraft technology develops through many incremental improvements as well as a few highly visible new designs. An efficient airplane depends on the whole system: its engines, aerodynamics, structure, controls and the way it is operated. A promising prototype is a different milestone from a certificated aircraft carrying passengers.
