We have updated our rules on double counting of emissions reductions. Double Counting is a risk that occurs where a Gold Standard carbon credit is issued from a project in a host country that engages in emissions trading (domestically or internationally). In these conditions it is possible that in addition to the claim on the Gold Standard credit a second unit is also inadvertently claimed by the host country or second buyer. This risk undermines the credibility of both the Gold Standard credit and the host country (or international) accounting.
