One way to improve the airline industry’s perceived environmental impact is for carriers to shout louder.  Ironically, the International Air Transport Association (IATA) calls for operators to make more noise comes as airlines claim to have reduced sound levels by 75 percent in the past 40 years.

In addition, fuel efficiency has been improved by 70 percent and soot eliminated, according to IATA director-general Giovanni Bisignani. He conceded at the group’s annual meeting in Vancouver this month that airlines will increase their carbon footprint by a half by 2020, but said the fleet would be 25 percent more fuel efficient by 2020.
