Article 6 Pipeline

Article 6 of the Paris Agreement provides a framework for countries to cooperate towards the implementation of their Nationally Determined Contributions (NDCs) through carbon markets (Articles 6.2 and 6.4) and non-market modalities (Article 6.8). These cooperative approaches can help countries to achieve and enhance their NDC targets. The overall objective is to increase climate ambition, promote sustainable development, and safeguard environmental integrity.  

Building on the extensive experience from the Clean Development Mechanism (CDM), as a first step, UNEP Copenhagen Climate Centre (UNEP-CCC) has set up an Excel-based database for Article 6 activities. The aim is to provide insights on the development of Article 6 projects, their contribution to countries’ NDC implementation and SDG achievement at the national and global level. Find a short video introducing this work here. 

UNEP-CCC will continue expanding this pipeline’s functionality as new Article 6 projects emerge and the modalities become clearer. Ultimately, the pipeline will take the shape of a more interactive and user-friendly platform. This will provide transparency and allow users to easily explore information on cooperation under Article 6. Additional background on projects potentially transitioning to the Article 6.4 Mechanism can be found in the CDM Pipeline and on the UNFCCC website 

CDM activities that are eligible and have requested transition to the A6.4 Mechanism 

The deadline for submitting requests has passed. In a new explainer video, we examine those activities that intend to transition using CDM methodologies and outline the next steps. 

Video on the CDM Transition (08:30 minutes) – find the slide deck here

As of 5 July 2024, transition requests were correctly submitted for 1,356 Project Activities (PA), 118 Programmes of Activities (PoA), and (together with these PoAs) 949 Component Project Activities (CPA) (see the figure below). While these numbers are close to the new potential maximum of CDM transitions, there may be additional activities for which re-submissions are possible after the first request did not meet procedural requirements.

Update: As of May, amendments for resubmissions were initiated for an additional 96 transition requests. For another 223 PA and PoA, there was no further communication with the UNFCCC after submitting the original request. For these 319 projects and programmes, authorized entities now have until 4 November 2024 to submit the corrected documentation. After this, the list of potentially transitioning activities is final.

Of the potential reductions of around 1.5 billion tonnes of CO2e that eligible activities could generate after transition while using CDM methodologies, this could amount to more than 900 million tonnes (60%). 

For more details (such as submissions by host countries, regions, and activity types) please refer to the sheet Analysis CDM Transition in the A6 Pipeline. The list of requests including the link for stakeholder comments can be found here. 


Summary of the Article 6 Pipeline’s other components: 

     1. Overview of the Bilateral Agreements and pilot projects/activities under Article 6.2 of the Paris Agreement  

Table 1 provides an overview of signed Bilateral Agreements (BA) for the cooperation under Article 6.2 of the Paris Agreement as of 5 July 2024.  

  • There are 83 BAs between 10 different buyers and 46 host countries 
  • A total of 140 pilot projects have been recorded, out of which 119 belong to Japan’s Joint Crediting Mechanism (JCM).  

Out of 140 pilot projects, 5 have Authorization Statements. The involved countries – Ghana (3x), Switzerland (4x), Thailand, Vanuatu – also submitted Initial Reports to the UNFCCC. The total expected amount of Mitigation Outcomes from these projects are:  

  • Promotion of climate smart agriculture practices for sustainable rice cultivation in Ghana (Ghana-Switzerland | Authorized Reductions: 1,126 ktCO2e) 
  • Bangkok E-Bus Program (Thailand-Switzerland | 500) 
  • Electrification of Vanuatu’s Inhabited Islands through Solar Power ITMO Programme (Vanuatu-Switzerland | 97) 
  • Integrated waste recycling and composting for methane reduction in Ghana (Ghana-Switzerland | 1,589)
  • Transformative Cookstove Activity in Rural Ghana (Ghana-Switzerland | 3,231)

On 15 December 2023, the first ever issuance of 1,916 ITMOs (Internationally Transferred Mitigation Outcomes) occurred for the E-Bus Program in Bangkok covering the period from October to December 2022. This transaction between Thailand and Switzerland is the first under Article 6.2 of the Paris Agreement. 

Table 1 – Bilateral Agreements (BA) between countries on Article 6 of the Paris Agreement and number of projects/activities within the framework of those BAs 

Blank cells mean that we have no knowledge of any dedicated Article 6 pilot projects between the two countries. Some countries who signed BAs do not yet publicly provide information on Article 6 pilot activities.   


    2. Overview of pilot projects/activities  

The identified pilot projects fall into following types:  

EE = Energy Efficiency
HFCs = Hydrofluorocarbons 

Out of the 140 pilot projects/activities, 78% have the host country in Asia, 12% in Africa, 6% in the Americas and 4% in Oceania.   


     3. Designated National Authorities for Article 6.4 Mechanism 

As of 1 July 2024, 84 Parties communicated their Designated National Authority (DNA) to the UNFCCC secretariat. More than half of all Parties in Africa (35 countries | 65%) have submitted information about their DNA, followed by Asia (23 | 48%) and the Americas (14 | 40%). Regular updates can be found here: Designated National Authority for Article 6.4 Mechanism | UNFCCC. 



Monthly news on Article 6 Pipeline: 

The June 2024 version of the Excel-based Article 6 Pipeline includes the following updates:

  • Benin has submitted the Host Party Participation Requirements outlining which activities it would consider approving for the Paris Agreement Crediting Mechanism (Article 6.4) and how this contributes to sustainable development.
  • 3 additional CDM transition requests were published (Project Activities in China, India, and Nicaragua).
  • A new indicator was introduced to analyse which activities use methodologies that are currently being revised by the Methodological Expert Panel.
  • Inclusion of an MoU between Indonesia and South Korea.
  • Two Parties indicated their Designated National Authority since the last update: Burkina Faso and Gabon. The DNA for Myanmar was removed from the UNFCCC’s database.
