Etihad Airways said Monday it is launching one of the world’s most fuel-efficient long-haul airplanes, part of a growing industry effort to reduce the environmental and financial costs of flying. Etihad’s “Greenliner” is a Boeing 787 Dreamliner that will depart on its first route from Abu Dhabi to Brussels in Jan 2020. Etihad’s CE Tony Douglas described the aircraft as a flying laboratory for testing that could benefit the entire industry. With fuel costs eating up around a quarter of airline spending, Douglas said the goal of the Greenliner is to be 20% more fuel efficient than other aircraft in Etihad’s fleet. Douglas said the aircraft “not only makes sense economically from a profit and loss account point of view, but because it also directly impacts the CO2 because of the fuel burn.” <br/>
