Carbon Emission certificates are traded like stocks. So just learn to read the market and of course they can put food on your table, and get you said table plus the villa which houses the dining room if you trade high volumes of those certificates.
Anyway, although that trading scheme is nonsense as long as it isn't done worldwide, the Europeans are hell bent on expanding it into aviation. In the end it will depend only on them chaining down planes of those airlines that do not participate. If they don't it will fall apart, if they do they can recover the costs that way. Personally I doubt it will happen, there are too many limp handshake persons in Europe.
