And while the point of your analogy is clear, your neighbor could only travel the world without remorse if they fund a huge number of new trees.
Offsets are not as illogical as you make them sound.
I'd love to read the details.
Here [0], Easyjet pretend to be offsetting 100% carbon emitted during their flights: https://www.easyjet.com/fr/developpement-durable
Where are the huge Easyjet forests? Planted just so the rich can fly?
I'm sure they have some kind of contract, somewhere, but I can't verify that. And of course any "new" tree can be attached to an offset, that isn't the problem. How can a third-party says that this tree wouldn't have been planted otherwise, when whole world has no choice but go greener/cleaner? All those who make genuine efforts would be stupid not to take the cash (prisoner dilemma). Carbon offsetting is buying time to slow down changes in devastating behaviors.
