المدربThe total number of allowances in circulation (TNAC) is the surplus of allowances held in the market: all allowances issued and not cancelled, minus those surrendered for emissions and those held in the reserve, published each year by the Commission. The market stability reserve (MSR) is a reserve into which allowances are withheld from future auctions when the TNAC is high, and from which they are released when it is low.
