Commercial aviation (along with much of aviation in general) has for more than a decade now been committed to "green" development, with much of the sector now dedicated to reducing polluting emissions with a goal of net zero by 2050.

But with the year-to-year expansion of global air traffic, it's been estimated that left unchecked, that less than three percent could rise to 20 by 2050.
