Eine neue Studie kommt zu dem Ergebnis, dass die Luftverkehrsemissionen durch die Kombination von drei Strategien um 50–75 % sinken könnten: Nur treibstoffeffiziente Flugzeuge fliegen, auf All-Economy-Layouts umsteigen und die Auslastung maximieren. Entscheidend ist, dass durch eine bessere strategische Nutzung bestehender Flotten die globalen Emissionen sofort um 11 % gesenkt werden könnten.

They already are maximizing load. They overbook flights. What they also do is fly empty planes because there’s a schedule. They only have so many planes.
They’re also not going to switch to more fuel efficient planes when current ones are cheaper. First class makes money, so that’s out too.
Now if you taxed CO2, then they might or just heavily tax Jet-A. $0.044 per gallon just doesn’t seem that bad.
You are not going to realistically have airlines switch to all economy layouts, in fact we are right now going through a period where they are increasing first and business class capacity.
1. Does that include the emissions from constructing a new fleet of fuel-efficient planes?
2. I’m not sure executives are going to buy into economy-layout only planes.
>>Global commercial aviation released between 892 and 936 Mt of carbon dioxide (CO₂) in 20191,2,3, contributing roughly 4% of the world’s net human-driven effective radiative forcing
that’s not 11% but also not nothing. some of the recommendations are sadly plain visionary
„all economy layouts“
So even less legroom and more packed like sardines.
The aviation industry still uses dot matrix printers.
Marinate in that for a second.
I would like to know how much % of global emissions could be reduced by limiting use of private jets. Especially in cases when the passengers are flying 500 miles for e.g., a dinner.
Maybe no private jets with one passenger?
Any meta analyzes to see if the increase in deaths from blood clots etc outweighs the deaths from the co2?
Point being is there is a price to be paid for packing people in like sardines.
What are all those other dots in North America? Shouldn’t there only be 23 in total?
I guess maybe including some non-sovereign nations on the North American plate.
Getting more plane traffic to electric train would help reduce carbon emissions.
But then CEOs would have to sit with the peasants and we can’t have that.
Wonder if they factor in that the increase in density would make trains and cars much more appealing
How about a climate tax on private jets? Would solve all of this in one simple step.
You know what else would help….Not flying empty flights just to keep your slots at an airport….
In other words, it will never happen
Aaaaaand avoiding routes that create contrails
Does someone remember the percentage of CO2 emissions that are from private jets?
Also banning same-continent flights under 2 hours would go a hell of a long way; short-haul flights are so wasteful. Why the hell are people flying from Paris to Brussels, or Rome to Milan?
