Airlines Efficiency Lie

In a rather timely manner, after my previous post, I read an article about some revelations in emissions caused by the airline industry. I wont lie, I am silently smug because it supports my argument that the airline industry can do more to improve its efficiency. The International Council on Clean Transport, who are behind the VW emissions scandal, released a report that suggested there was a 51% difference in fuel efficiency between the most pollutant and cleanest airline.
