I'm not sure what your point is, but I wouldn't trust Ryanair's suggestion of how much to pay to offset their CO2 emissions, or that they'd use that fee effectively.

It tells you something about how expensive it would be to have someone else save the CO2 you have emitted by flying a plane.

But you are right. The price going to purchase the CO2 offset is probably less than what I would be paying.

I don’t think that was his point. He is saying you can neither assume that this fee is enough to offset the carbon, nor that Ryanair will spend it appropriately. Just because it says carbon offset doesn’t mean all of the carbon is offset.

If the true price were actually that low, it would be easy to solve.
