Projects registered under the Kyoto Protocol’s Clean Development Mechanism (CDM) can ask to move to the Paris Agreement’s crediting mechanism under Article 6.4. As read on 10 November 2026, the UNEP Copenhagen Climate Centre’s Article 6 Pipeline lists 1,510 CDM projects and programmes that made that request. 417 of them are listed as approved, and 37 of those are already registered under the new mechanism. The other 1,093 show no approval, and 987 of them — nine in ten — are in two countries: China (527) and India (460).
What each stage means
The pipeline sorts every CDM activity that asked to move into stages, as it lists them on the day of the read. In the words of its glossary:
- Transition requested: «CDM activities for which the activity participants have submitted a formal request to transition to the PACM».
- Approved by Host Party (CDM): «CDM activities for which the transition request has been approved by the respective Host Party».
- All Registered: «Projects that have been approved and are officially registered in the PACM registry».
PACM is the Paris Agreement Crediting Mechanism, the name of the Article 6.4 mechanism. Approvals were due by 30 June 2026 (decision 20/CMA.7, paragraph 25).
The numbers, as read on 10 November 2026
| Stage in the pipeline | CDM projects and programmes | Most in |
|---|---|---|
| Transition requested, no approval listed | 1,093 | China 527, India 460, Viet Nam 21, Colombia 15, Republic of Korea 10 |
| Approved, not yet registered | 380 | Brazil 93, Chile 29, Viet Nam 23, Thailand 19, South Africa 17 |
| Registered under Article 6.4 | 37 | Nepal 8, Bangladesh 7, Uganda 5, Indonesia 3 |
Projects and programmes of activities (PoAs), each counted once at its furthest stage; the components of a programme are not counted apart. The 417 approved activities are in 57 countries, plus 14 programmes listed with no single country; Brazil has 93 of them, Chile 29 and Viet Nam 23.
China and India
China’s 527 requests are 526 projects and one programme; India’s 460 are 445 projects and 15 programmes. On 10 November 2026, none of them appears in the pipeline as approved or as registered under Article 6.4. The pipeline records the stage each activity has reached; it does not give reasons, and this article gives none.
Where to see a project’s stage
A CDM project that asked to transition shows its stage on its CarbonMeld page, as last read from the Article 6 Pipeline, with the date of that read. The CDM standard page lists the projects, and the country pages for India and China list each country’s. For the background, see why most legacy CDM credits are being left behind in the new UN market and the first Article 6.4 methodology for renewable power.
