家园 SOx and CO2 trading

My understanding about why SOx and CO2 trading work so differently:

SOx (and NOx too) trading was a more sectoral approach: the trading was largely between big utility companies, so it is trading oranges with oranges, and with the players more or less on the same knowledge level. Thus the transaction cost is reasonably now, plus information transparency -> efficient market.

But the CDM CO2 trading is more like trading oranges with elephants or whatever, huge information asymmetry among different players, so there are tons of loopholes and transaction cost -> market failure.

村长觉得如何?
