The Patience Method: Sitting Longer at the Gate Could Cut Airplane CO2 Emissions

We may not yet be able to power large airplanes sustainably with biofuels, but there are still ways that the airline industry can easily cut down on its fuel use and CO2 emissions. One ultra-simple solution: Keep planes at the gate longer with their engines turned off instead of having them idle on the runway. The idea comes courtesy of Hamsa Balakrishnan , an MIT professor specializing in airspace efficiency, in a paper published in the MIT Technical Report ( PDF )
