Article 6 Updates: September 2026

September 2026 marked another month with developments across Article 6.2, 6.4 and beyond. For further insights see our Article 6 101 and Article 6 Observatory Resource Hub. If you are interested in diving deeper the Article 6 Observatory is open to applications from independent stakeholders. Read more and apply here. 

Article 6.2

UNFCCC Developments 

Details on the forthcoming Article 6.2 Ambition Dialogue at COP31 were released. The focus of the Dialogue will be on how “Parties approach authorization in practice, including how considerations related to NDC implementation, environmental integrity, safeguards and other relevant national circumstances inform their decision-making”.

A report on Fees and Levies under Article 6 was also released, detailing strategic considerations of Host Parties in pricing ITMOs and their transaction-related costs.

Country-level engagements 

On 4 September, Singapore and Lao PDR signed an Implementation Agreement on carbon credits cooperation under Article 6 of the Paris Agreement. The agreement establishes the bilateral framework through which authorised carbon credits can be transferred between the two countries, including how corresponding adjustments will be applied. This marked Singapore’s twelfth Article 6 Implementation Agreement and its fourth with another ASEAN Member State. (⁠Ministry of Trade and Industry).

On 8 September, Thailand and Switzerland completed the issuance of 57,327 ITMOs from the Bangkok E-Bus Programme for emission reductions achieved during 2025. The programme has now generated 108,960 ITMOs since implementation. The units are purchased by the KliK Foundation and are intended to contribute towards Switzerland’s NDC. 2 % of the issued ITMOs were deducted and cancelled for Overall Mitigation in Global Emissions (OMGE), in line with the PACM rules. Alliance Sud has conducted an investigation into this project, which questions the additionality of these emission reductions. You can access the investigation here.

On 21 September, Tanzania issued BURN, a second Letter of Authorisation under Article 6.2, covering up to 785,000 tCO2e carbon credits intended for use under CORSIA. 

The Democratic Republic of the Congo expanded an existing Article 6 authorisation for Econetix by up to an additional 2 million tCO₂e, bringing the cumulative authorised volume under the programme to 2.75 million tCO₂e, including for CORSIA purposes. The extension, signed on 1 September, covers a Gold Standard clean energy programme implemented with ALTECH Group, which includes solar lighting, solar home systems and clean cooking activities.

On 25 September, Senegal and Switzerland announced the authorisation of the Senegal Mass Car Electrification Programme, the first mitigation activity authorised under the bilateral Article 6.2 cooperation between the two countries. The programme aims to replace ageing internal-combustion vehicles used in Dakar’s taxi and ride-hailing fleets with electric vehicles and generate ITMOs for transfer to Switzerland. 

On 24 September, the Government of Canada announced that it is exploring a policy framework for both buying and selling ITMOs. Environment and Climate Change Canada stated that the framework could facilitate Canadian participation in international carbon markets and support investment in mitigation activities, including in carbon dioxide removals (CDR) and nature based solutions (NbS).  

The Initial Technical Expert Review for Japan was released, noting two significant inconsistencies.

Finally, on 29 September, the UNEP Copenhagen Climate Centre launched its NDC Tracking and Corresponding Adjustment Tool (NDC-CAT). The Excel-based tool is designed to help Parties integrate NDC progress tracking with Article 6 accounting, ITMO records and corresponding-adjustment calculations, including for reporting through Biennial Transparency Reports (BTRs) under the Enhanced Transparency Framework. 

Article 6.4

Work on methodologies under PACM continued during September. The Methodological Expert Panel held its 16th meeting from 7–11 September in Bonn, continuing its work programme on methodologies and methodological tools for the mechanism. 

The user guide for the interim mechanism registry was also updated.

From 10 September-1st October a consultation opened on proposed methodology A6.4-PMM011: Hydrogen production from electrolysis of water powered primarily by renewable electricity. An earlier consultation on A6.4-PMM010: Partial substitution of fossil fuels by municipal solid waste in cement manufacture closed on 14 September. 

Preparations also advanced for the 23rd meeting of the Article 6.4 Supervisory Body (SBM23), scheduled for 5–9 October in Bonn. The annotated agenda and supporting documents released in September include proposed revisions to the activity cycle procedure, activity standard and validation and verification standard for projects to incorporate requirements relating to non-permanence and reversals. The meeting will also consider methodological work including cooking energy transitions and reversal risk assessment, as well as the Supervisory Body’s annual report to CMA8. You can watch a livestream here.

On 28 September, 112 coalitions and organisations from 42 countries and 5 continents, sent a joint letter to the members of the Article 6.4 Supervisory Body, demanding that more rights-based provisions are included in the PACM Sustainable Development Tool - set for revision in the next SB meeting 5-9 October. 

Article 6.8

During September, Article 6.8 received increased attention due to the UNFCCC’s regional implementation activities. On 10 September, the UNFCCC held an “Article 6.8: Understanding and engaging with non-market approaches” workshop during Climate Week 4 in Baku. The workshop examined how Parties can use non-market approaches to support NDC implementation through forms of international cooperation involving areas such as finance, technology development and transfer, and capacity-building. 

The UNFCCC also updated its Frequently Asked Questions on non-market approaches under Article 6.8. The resource explains the Article 6.8 framework, the Glasgow Committee on Non-market Approaches and the role of the NMA Platform in facilitating cooperation between Parties and non-Party stakeholders. 

Towards the end of the month, the UNFCCC published the concept note for the Article 6.8 in-session workshop at the tenth meeting of the Glasgow Committee on Non-market Approaches (GCNMA 10), which will take place during SBSTA 65. 

CORSIA

Article 6 authorisations continued to expand the potential supply of CORSIA Eligible Emissions Units during September. As noted above, Tanzania and the Democratic Republic of the Congo’s expanded authorisation of CORSIA activities. 

On 28 September, more than 1.7 million credits from DelAgua’s Rwanda clean cooking activities were tagged on the Verra Registry as eligible for the first phase of CORSIA. The tranche comprises 1,114,166 credits from VCS4150 and 635,458 credits from VCS3699. This follows Rwanda’s Article 6 authorisations and adds to the growing pool of correspondingly adjusted credits available for use by airlines during CORSIA’s first phase. 

The EU also released an assessment of CORSIA’s implementation in the EU.

These developments come as airlines approach the end of the 2024–2026 first phase of CORSIA, increasing attention on the availability of emissions units that satisfy both ICAO eligibility requirements and the Article 6 authorisation and corresponding adjustment requirements applicable to eligible credits.
