UNFCCC CDM carbon credits were listed for trading through a voluntary electronic exchange platform. A study on CDM CER unit supply potential through 2020 found that the estimated potential supply is considerably lower than ex ante reduction estimates in project design documents for the same period. A study on CER supply potential published by the NewClimate Institute estimates the potential supply of CERs from projects registered under the CDM from 2013-2020 at 4.7 billion CERs, of which 82% are not deemed vulnerable.
