Not only the billionaires, even the millionaires, and all the people taking the plane more than once a year. It is an ecological crime the pollution of air transport.
Edit #2: ICE is a type of train in germany. I mistook “ICE cars” as meaning trains and was wondering how flying is supposed to be more efficient than trains. Hence my confusion.
OG comment (invalid, see Edit #2):
Where are these numbers coming from?
I cannot find any source for the 3-4l/passenger/km claim. I cannot find any source for the claim that planes are more efficient. Nothing comes even near this claim.
Edit #1: I just want to add that my old combustion car (VW Up! / Seat Mii / Skoda Citigo) burned around 4.2l/100km. So I according to you, if I had another person with me, I’d beat both planes and trains with what stands uncontested as the most inefficient form of transport?
Since I just had this whole back and forth with someone else a few days ago, I have these handy. I’m not the parent, but he’s right. An individual car can be more fuel efficient with 3+ passengers but the average car trip is only 1.3 passengers. The most popular use of a car is commuting and that stands at 1.2 passengers per trip.
“A new report from the University of Michigan’s Transportation Research Institute shows that flying has become 74% more efficient per passenger since 1970 while driving gained only 17% efficiency per passenger. In fact, the average plane trip has been more fuel efficient than the average car trip since as far back as 2000, according to their calculations.”
“The main findings are that to make driving less energy intensive than flying, the fuel economy of the entire fleet of light-duty vehicles would have to improve from the current 21.5 mpg to at least 33.8 mpg, or vehicle load would have to increase from the current 1.38 persons to at least 2.3 persons.”
A lot of those flights could be replaced with high speed rail. Maybe not New York to LA, but a lot of people live in the cities in the northeast and travel between those cities would be very feasible at reasonable travel times with high speed rail.
Okay let me just lobby the government to build long distance high speed rail before I take my trips.
High speed rail makes more sense for sure, but it’s not available in most of the country. There’s only two stretches in the US, in the northeast corridor and surprisingly in Florida
I know how pitiful our rail networks are. I take Amtrak regularly. It’s faster to drive. It shouldn’t be, but it is. Obviously I’m not talking about today, but building improved rail infrastructure over the next decade is very realistic and a worthwhile investment. Unfortunately the investment Amtrak has gotten isn’t enough to modernize our rail network, and a lot of that money is being used to improve privately owned rail lines that Amtrak leases for their passenger service.
My point was that the US doesn’t have distances that are insurmountable that can only be traveled via plane. It’s an investment issue.
efficient ICE cars consume ~6l per passenger per 100km.
More like 6L per 100km, whatever the number of passengers, I suppose. So it’s usually still less than planes.
And there are better alternatives like trains or buses, which can be actually efficient for long distance travels (high speed trains, night travel. Works well from city centre to city centre)
There is also the additional issue of contrails which are a massive factor of greenhouse effect
Is that planes that are packed to the gills or private planes that actually have space that people aren’t crammed into?
Also, 3-4/6 liters of what? ICE cars and modern planes aren’t burning the same fuel, so I’m not sure what this is intending to portray by directly comparing how much of each (in liters) that they burn (serious question, no snark)
Yeah gotta agree with you. I have to fly a good amount, both families live over 2000 miles away, it’s unavoidable. But I change what I can in society, I am switching to an EV, I pay extra on my electricity to pay for green sources, and I overall try to lower my carbon footprint.
As soon as they come out with an alternative fuel airline I’ll be flying on that as much as possible, but until there are alternatives I’m stuck flying.

fun fact. modern planes consume ~3-4l per 100 passengers per km or 3-4l per passenger per 100km.
efficient ICE cars consume ~6l per passenger per 100km.
add to that, that there’s basically no good alternative to fast very long distance or cross-continent transport

I think you need to learn how to read, buddy.
The alternative is stop traveling such huge distances all the time.
Other than public transportation and filling up the cars with people, instead of having one vehicle per person.
Distances that require a flight are far too common here in the US at least, it’s kind of unavoidable
A lot of those flights could be replaced with high speed rail. Maybe not New York to LA, but a lot of people live in the cities in the northeast and travel between those cities would be very feasible at reasonable travel times with high speed rail.

This ICE car consumes 0.15-0.2l per passanger per 100km
One plane flight a year? What if I want to return home the same year?
You don’t, wait the next year or don’t leave home.
The trick is to go a week before new year’s
But the foreign country only lets me stay for 3 months, and in any case I only get 4 weeks leave

Oh yeah let’s go full authoritarian, that’s what leftism does best after all
What…? Are you responding to the wrong person?
What’s magical about that once-a-year limit? I find that quite a lot already.
Probably you right
