This fact sheet surveys the role of Article 6 of the Paris Agreement (PA) in the Nationally Determined Contributions (NDCs) that Parties have submitted to the UNFCCC. The findings indicate that there is in general considerable openness towards Article 6, with the intention to buy ITMOs or A6.4ERs being much more limited than to sell such units. The distribution between sellers vs. buyers largely reflects the structure known from the Kyoto Protocol and its Clean Development Mechanism (CDM), indicating that the distribution of roles might persist under the Paris Agreement.
