    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.

      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

        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.

        https://ourworldindata.org/travel-carbon-footprint

        https://www.eea.europa.eu/publications/rail-and-waterborne-transport

        https://www.bbc.com/news/science-environment-49349566

        Can you please provide a source?

        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.”

          http://websites.umich.edu/~umtriswt/PDF/UMTRI-2014-2_Abstract_English.pdf

          “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.”

        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.

        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)

      One plane flight a year? What if I want to return home the same year?

        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.

      What’s magical about that once-a-year limit? I find that quite a lot already.

      Admittedly, I am one of those people taking a plane well over once a year, although I really rather wish I weren’t - I haven’t had a personal trip in over four years, it’s all onsite implementation.
