Aviation is a major climate problem, but electrification and biofuels are solutions
Aviation is a major source of greenhouse gasses, punching above its weight due to additional forcing factors of contrail- and nitrous oxide-related warming in addition to direct carbon dioxide emissions. It’s in the same range of total greenhouse gas emissions as hydrogen manufacturing as a hard-to-decarbonize segment. It’s going to decarbonize, whether the industry likes it or not, because the climate implications are sufficiently significant that it must.
