Status of CDM projects
In total 8418 CDM projects are now included in the Pipeline excluding the 279 projects given a negative validation by DOEs, the 2380 projects where DOEs terminated the validation, the 280 rejected by EB and the 64 withdrawn. 7857 of the projects are now registered and 2 are in the registration process. 3315 CDM projects have got CERs issued.



2075 Million CERs have been issued. The first column  shows that 1485 MCERs were issued in the period 2008-2012.  The second column shows that 595 MCERs have been issued in the second crediting period. The total issuance in the period 2008-2021 was  2080 MCERs.


Number of CDM projects starting the public comments period each month, the number of them that have requested registration, the number of them that have CERs issued, and the number of them that was rejected by DOEs.

No new CDM projects were added to the pipeline in ay 2021


CERs expected until 2020 in CP2 from CDM projects in each sector
While 71% of the CDM projects are renewables, they  take 55% of the CERs in CP2. Energy efficiency takes 9% of the CERs  for Supply-side EE and only 1% for Demand-side-EE (see sub-page on types).


The monthly average time delay from the start comment date to the date of registration has now decreased to about 100 days.


ERUs expected until 2012 from JI projects ( % in each category)
While 18% of the 761 JI projects are renewables, they only take 3.6% of the ERUs. CH4 and fugitives reduction  takes the majority (53.8%) of the ERUs.

Review history

The graph above shows the total number of project requesting registration each year (we use the date of signature in the request registration letter from the DOE). The yellow bar shows the number of these projects, that are registered automatically. The graph shows that this fraction has gone down from 92% in 2005 to 31% in 2008. After that the system improved and in 2012 94% was again registered automatically like in the beginning of CDM. Now 98% are registered automatically.
