Spirit Airlines has announced it is going out of business after 34 years. The ultra-low-cost airline known for its bright yellow planes and deep discount fares said Saturday it has started winding down operations.
The elephant in the room is obviously the “domestic flight” emissions number sitting proudly at the top of the list. Based on the average length of a UK domestic flight and this source, that’s 20% of all global commercial flights, and just under 50% are under 500 nautical miles/926km, which is still on the highly inefficient end of the spectrum. But then you realize that it only accounts for about 42 million weekly seats when estimates are much closer to 100 million, then you realize it’s 2009 data and you don’t want to deal with this rabbit hole…
That second chart you provided is… tantalizing, and just like my own source I’d much rather have access to the data than the charts they’ve made with it, because napkin math based on their red line falls shy of any sort of accuracy.
If we just rely on the provided numbers, new European internal combustion vehicles are way more efficient than short and long haul flights (cars’ grams of CO2/km should should be divided by ~1.5, which is the US/EUR average vehicle occupancy rate), and the average is dragged down by older ICE cars. New U.S vehicles lose the efficiency battle comically and are about as bad as ultra short haul business flights, lmao. Thanks for the link.
