This publication provides insights on deliberations regarding the Clean Development Mechanism (CDM) transition and implications for Asia and the Pacific. With the Article 6 Rulebook expected to be finalized at the 26th Conference of Parties in Glasgow, the Asian Development Bank hopes this publication can increase knowledge and understanding of the CDM transition along with its relevance to economies in the region. It is also intended to help stakeholders from Asia and the Pacific become better prepared to contribute to the finalization of the Article 6 Rulebook and move toward operationalizing Article 6 of the Paris Agreement.
