41832What is conveniently overlooked is the fact that aviation’s contribution to global emissions varies from two per cent to five per cent or more, depending on who’s counting.

There is added complexity because the nitrous oxides created are 310 times more powerful than carbon dioxide, and the effects from condensation trails (contrails) are difficult to quantify.
