Transportation - Fossil fuel reduction opportunities - airplanes 3 Items
Our airplane efficiency gain is derived from studies of new airplane designs within each of the major airplane size classes: narrowbody, widebody, and regional. Efficiency gains for each future airplane design are relative to existing 2010 designs.
Decades of improvements in airplane efficiency, logistics, and load factor slashed the fuel burned per seat by 82% during 1958–2010. Compared to early airliners like the Comet 4, engine fuel consumption has dropped by nearly 50%.
Considering historical technology adoption in aviation and entry into service dates for advanced airplanes, the majority of today’s planes could be replaced with more efficient versions by 2050.
