But what about all that CO2 compensation stuff, that's really not expensive, in fact it seems like it can't work. What would be real cost to undo all damage I do to the world with a flight? I don't mind paying more. But how much more are we talking about? That is the real question imho. Edit, a recent example, as calculated using https://co2.myclimate.org/ https://co2.myclimate.org/ Your flight: From: Amsterdam (NL), AMS to: Pogdorica (CS), TGD via: VIE, Vienna International, Austria, AT, Roundtrip, Economy Class, ca. 3,300 km, 1 traveller CO2 amount: 0.746 t Take responsibility for your CO2-emissions by supporting climate protection projects in developing and emerging countries. EUR 21.00 To compensate it asks me to pay 21 eur. That's nothing. Just add it to all flights. Actually, it doesn't say that this will undo my emitted CO2. So what does this do? Stimulated eco friendly projects. Of course it would be better to stimulate them AND avoid the flight... I wonder what it would cost to really really just remove that CO2 from the atmosphere.

There’s some good evidence that many carbon offsetting programmes don’t work. E.g. https://news.ycombinator.com/item?id=37660256 https://news.ycombinator.com/item?id=37660256 And there’s probably an argument that taking flights increases general demand for them and that most of that demand comes from people who don’t offset their CO2

That's an extremely optimistic calculation. More realistic is $1-200/tonne. https://www.cell.com/joule/fulltext/S2542-4351(18)30225-3 https://www.cell.com/joule/fulltext/S2542-4351(18)30225-3

I made a calculation for one of the projects posted here https://news.ycombinator.com/item?id=36093771 https://news.ycombinator.com/item?id=36093771 and (after fixing an error pointed out by jlund-molfese ) I got: > For comparison, 1 gallon of gasoline release 9kg of CO2, so it's $12.15 USD more per gallon to be carbon neutral. Let's be optimistic and assume that other projects are better and the cost is a half, i.e. $6 USD A gallon of gasoline cost $4 USD (Planes don't use gasoline, but whatever.) From a random link I got from Google, the 40% of the cost of a plane trip is fuel https://www.quora.com/What-percentage-does-fuel-cost-take-out-of-the-total-cost-for-a-single-airline-flight https://www.quora.com/What-percentage-does-fuel-cost-take-ou... So the price goes from 60%+40%=100% to 60%+(6+4)/4*40%=160%. To simplify, just assume you will have to pay a 50% more per trip. [This assume there is another project that can capture carbon for half of the cost of the linked project. For the full price you get 60%+(12+4)/4*40%=160%, i.e. a +120% increase. And this is very optimistic, because preliminary calculation are usually too optimistic.]
