> Price is volatile, depending on weather and season Not sure why you think that is a problem. Emissions depend on weather and season. It would not be a market if it didn't react to relevant aspects of reality. > price per metric ton should be $50 There are too many certificates, agreed. I wasn't surprised to read that Parliament advocated stricter rules. > Politics - elections, growth, and other factors play a significant role in setting cap and price. I don't find that in the article. It does say that the Commission screwed us over by empting airlines, but well, that's what we expect from the Commission. Anyway, so far I'm not convinced about the alleged loopholes mentioned above. The system doesn't work as an efficient market, that is true. As far as I can tell, that could be fixed by stricter caps.
