Also don't buy 20 pairs of jeans etc per year.

The cheap "fast-fashion" these days has a hidden cost you don't pay directly. And its HUGE.

Airliners get better fuel efficiency per mile per passenger than most single-occupant cars.

The majority of people do not fly multiple times per week.

Having said that, I do agree with the main thrust of your comment: consume less.

They also don't drive several thousand or tens of thousand kilometers in one go once or more a year either in addition to the normal driving, so I'd say that argument is not helpful here.

That’s a good point.

I wonder how many people are willing to eat less beef vs how many are willing to give in their once a year or less long-haul-flight holiday.

That's not how it'll work though. Do vegans get more flight allowances? Do people with kids have to forgo meat as well as vacations?

Obviously no consumer choice driven solution is going to work. The costs have to be included in the goods and services if we want any actual reduction.

Calculating the detrimental costs of air travel is more complex then just fuel burn due to altitude and types of emissions produced: https://en.wikipedia.org/wiki/Environmental_impact_of_aviati...

http://www.greenrationbook.org.uk/resources/footprints-air-t... seems to disagee. In fact, driving a typical car for one year produces less CO2 than one long-distance flight per passenger.

That paper says, multiple times, that flying is about the same, or better, or worse, CO2 emissions per mile than single occupant cars.

Per passenger. Therefore, a single passenger on a single 8000 mile flight produces as much CO2 as an average family car in a year (where I live - 13000 Km/year).

The calculator they base the plane numbers from seems off. Not counting passengers/plane or something.
