Emirates plans to operate the first global cross-polar green flight on its service launch from Dubai to San Francisco on 15 December. The carrier is working with the governments of Russia, Iceland, Canada and the US to optimize routings for the aircraft and possibly achieve a continuous descent approach to minimize fuel burn. The carrier aims to save roughly 7,570 litres of fuel and 30,000lb of carbon emissions on the 16-hour flight. Other fuel and emission saving procedures planned for the flight include a special washing pre-flight to minimize drag, a pre-planned priority departure route from Dubai supplying unimpeded climb to cruise altitude and minimal thrust on landing and single engine taxi to the gate.
