What ITMOs are under Article 6.2 of the Paris Agreement, how they are authorised and transferred, the role of corresponding adjustments, and why the GCC is an active player.
Introduction
When the Paris Agreement lets one country’s emission reduction count toward another country’s target, the thing that actually changes hands is an ITMO — an Internationally Transferred Mitigation Outcome. It is the workhorse unit of Article 6.2, and it is central to how the GCC is engaging with global carbon markets. This guide explains ITMOs in detail. It builds on our overview of Article 6.
What an ITMO is
An ITMO is the unit traded between countries under Article 6.2. It represents a host-country-authorised mitigation outcome — typically tonnes of CO₂e — transferred toward another party’s climate target (NDC). Where a voluntary carbon credit is a private-standard unit for company claims, an ITMO is a government-authorised unit for national-target accounting.
ITMO vs voluntary credit
| Voluntary credit | ITMO | |
|---|---|---|
| Issued by | Independent standard (Verra, etc.) | Host-country authorisation |
| Counted toward | Company voluntary claims | National target (NDC) |
| Double-count control | Registry retirement | Corresponding adjustment |
| Space | Voluntary market | International cooperation (Article 6.2) |
Importantly, the two can meet: a host country can authorise a credit from a voluntary standard, turning it into an ITMO.
How ITMOs are authorised and transferred
The mechanics, finalised at COP29:
- Two countries agree a cooperative approach under Article 6.2.
- The host country authorises a mitigation outcome for transfer.
- On the ‘first transfer’, the host applies a corresponding adjustment.
- The transaction is reported transparently under UN rules.
A voluntary credit is retired on a registry. An ITMO is authorised by a government and balanced by a corresponding adjustment. Same idea — no double-counting — enforced by very different machinery.
Why the GCC is an active player
GCC states are engaging with Article 6.2 as both hosts and buyers. The UAE’s National Register for Carbon Credits (Cabinet Resolution 67 of 2024) explicitly requires credits to align with Article 6, and the UAE is pursuing bilateral agreements to cooperate on mitigation outcomes. For the region, ITMOs are part of the pathway toward net-zero targets — and a potential export, given the Gulf’s project pipeline. See carbon credits in the GCC.

ESGweise helps GCC organisations understand where ITMOs fit — eligibility, host-country authorisation, corresponding-adjustment requirements, and how Article 6.2 cooperation interacts with voluntary credits and national registers. See our carbon and strategy practices.

Conclusion
ITMOs are the unit that makes Article 6.2 work: host-country-authorised mitigation outcomes, transferred toward a buyer’s national target, and balanced by a corresponding adjustment so no tonne is counted twice. They sit alongside — and sometimes overlap with — voluntary credits, and the GCC, led by the UAE’s Article 6-aligned National Register, is an active player as both host and buyer. For anyone engaging with international carbon markets, understanding ITMOs is understanding how climate cooperation actually settles accounts.
Frequently asked questions
What is an ITMO?
An ITMO — Internationally Transferred Mitigation Outcome — is the unit traded between countries under Article 6.2 of the Paris Agreement. It represents a mitigation outcome (typically measured in tonnes of CO₂e) that a host country has authorised for transfer to another country or entity, to be counted toward the buyer's climate target (NDC). ITMOs are the vehicle for bilateral, government-to-government carbon cooperation under the Paris Agreement.
How is an ITMO different from a voluntary carbon credit?
A voluntary carbon credit is issued by an independent standard (like Verra or Gold Standard) and used mostly by companies making voluntary claims. An ITMO is a government-authorised unit transferred under Article 6.2, counted toward a national target (NDC), and subject to a corresponding adjustment by the host country. ITMOs sit in the international compliance-cooperation space, though authorised credits from voluntary standards can, in some arrangements, become ITMOs when a host country authorises them.
How are ITMOs authorised and transferred?
The host country authorises a mitigation outcome for international transfer under a cooperative approach agreed with the buying country, within the Article 6.2 rules finalised at COP29. On the 'first transfer', the host country must apply a corresponding adjustment — adding the transferred tonne back to its own inventory — so it is not double-counted. The transaction is reported transparently under UN rules, giving the buyer confidence the outcome is genuinely additional to the host's own accounting.
Is the UAE using ITMOs?
Yes. The UAE is an active participant in Article 6.2, pursuing bilateral agreements to cooperate on mitigation outcomes, and its National Register for Carbon Credits (Cabinet Resolution 67 of 2024) explicitly requires alignment with Article 6 of the Paris Agreement. Several GCC states are positioning themselves as both hosts and buyers of ITMOs, using Article 6.2 cooperation as part of their pathways toward net-zero targets.
