Article 6 Updates: August 2026
Welcome to the Article 6 Observatory’s monthly update reviewing the latest developments from around the world related to Article 6.
August 2026 saw further evidence of Article 6 moving from institutional readiness towards implementation. Zambia launched its national carbon registry and, within the same month, authorised its first two mitigation activities with Switzerland; Rwanda authorised more than 1.7 million mitigation outcomes for international transfer and potential CORSIA use; and Viet Nam completed an important domestic step towards operationalising its bilateral Article 6 agreement with Singapore.
At the international level, new infrastructure was introduced to support the reporting of corresponding adjustments through Parties’ 2026 Biennial Transparency Reports, while work continued on methodologies under Article 6.4 and the UNFCCC published a new report on implementation of Article 6.8 non-market approaches.
Article 6.2
Zambia made several steps towards operationalising Article 6.2 during August. On 7 August Zambia launched its Carbon Registry, developed with support from the Supporting Preparedness for Article 6 Cooperation (SPAR6C) programme. The first phase focuses on Article 6 activities, with broader carbon market coverage expected subsequently. This was followed on 17 August by the authorisation of the BioLite Improved Cookstoves activity by Zambia and Switzerland under Article 6.2, facilitated by the KliK Foundation. The activity aims to distribute more than 160,000 fuel-efficient cookstoves in Zambia in order to produce Internationally Transferred Mitigation Outcomes (ITMOs). It is the first mitigation activity authorised under the Zambia–Switzerland bilateral cooperation. On 31 August, Zambia and Switzerland authorised a second activity, Modern Energy Cooking Zambia which seeks to replace charcoal used for cooking with biomass pellets manufactured from local sawmill residues.
On 14 August, the Government of Viet Nam adopted Resolution No. 235/NQ-CP, approving the Article 6 Implementation Agreement between Viet Nam and Singapore that was signed in September 2025. Singapore also updated its participation criteria for selling or transferring ITMOs, including eligibility criteria, required documents, and consequences for non-compliance.
Ecuador also took further steps towards operationalising Article 6 participation with the adoption of its first detailed domestic framework for managing mitigation outcomes: The Technical Standard for the Authorization, Registration, Traceability and Transfer of Mitigation Outcomes (ARTTRM). It also establishes conditions for the application of corresponding adjustments.
Private crediting standards, Gold Standard and Verra launched a joint Article 6.2 Corresponding Adjustments Reporting Tool to assist host countries in reporting corresponding adjustments for carbon credits authorised under Article 6.2. The tool provides a consolidated record of corresponding adjustments associated with authorised credits issued by the two standards. After information concerning a Party’s NDC target, accounting approach and terms of authorisation is entered, it can automatically populate the relevant structured summary table required for Article 6 reporting. The tool is particularly intended to support host countries preparing their 2026 Biennial Transparency Reports (BTRs), which are due by the end of December 2026.
Rwanda also authorised 1.77 million mitigation outcomes for international transfer and CORSIA from the Rwandan Improved Cookstove Project (VCS 2984).
Article 6.4
On 24 August, the Article 6.4 mechanism opened a public consultation on proposed methodology A6.4-PMM010: Partial substitution of fossil fuels by municipal solid waste in cement manufacture. The consultation runs from 24 August until 14 September, and the UNFCCC form has to be utilised.
Article 6.8
On 24 August, the UNFCCC secretariat published FCCC/SBSTA/2026/6, reporting on the in-session workshop under the framework for non-market approaches referred to in Article 6.8 of the Paris Agreement. The report covers the workshop held during SBSTA 64 in Bonn on 9 June 2026 and summarises presentations, discussions and exchanges concerning implementation of the Article 6.8 work programme.
CORSIA
The first CORSIA Eligible Emissions Units from UpEnergy’s Nigerian clean-cooking project (VCS2673) was tagged for use under CORSIA following authorisation from Nigeria’s National Council on Climate Change under Article 6. The relevant Letters of Authorisation provide forward visibility covering nearly four million tonnes across their relevant Nigerian activities (UpEnergy 1 and 2).
ICAO’s Technical Advisory Body continued its 2026 assessment cycle for carbon-crediting programmes seeking eligibility to supply CORSIA Eligible Emissions Units. Twenty-five organisations submitted applications during the 2026 application period for eligibility to supply units during the 2027–2029 CORSIA compliance period.
