This technical paper was prepared to support the Subsidiary Body for Scientific and Technological Advice at its sixty-first session in considering the functioning and operation of the processes and institutions under the clean development mechanism in the future. The paper presents a further breakdown of the necessary level of resources for the activities, processes and institutions that need to continue under the clean development mechanism, beyond the information provided previously on this matter, and includes information on modalities for transferring available funds in the trust fund for the clean development mechanism to the Adaptation Fund and to other areas potentially in need of funding.
