Is anybody making decisions?

Sir Richard Branson at Virgin is lobbying the idea that all airplanes be towed from the gate to the runway rather than turn on their engines at the gate and then remain, engines running, for minutes (or hours) waiting for a take-off slot.

He said that if this was applied to all airplanes, “8 to 9 % of the carbon produced by airlines could be avoided”. [via Bruno Giussani]
