How are carbon credit transactions structured and disputed under UAE law?

A UAE carbon credit transaction sits inside three layers of regulation, two registration regimes, and one of the busiest dispute environments in commodity markets right now

Carbon credits are not commodities in the traditional sense. They represent emission reductions that are real, additional, measurable, verifiable, and permanent. UAE law now treats them through three frameworks at the same time. Federal Decree-Law 11 of 2024 imposes emissions reduction obligations and a sectoral compliance regime. Cabinet Resolution 67 of 2024 establishes the National Register for Carbon Credits and the MRV machinery. ADGM regulates voluntary carbon credits as environmental instruments under FSRA supervision, with AirCarbon Exchange operating the world's first fully regulated carbon spot exchange and clearing house. UAE entities active in carbon trade have to navigate all three. Disputes under each are different. Counterparties get them confused.

• The 30 May 2026 compliance deadline for Entities of Huge Carbon Emissions makes carbon transactions urgent for any UAE entity above 0.5 million tCO2e annually.
• Cabinet Resolution 67 of 2024 establishes the National Register for Carbon Credits and the SCA-supervised trading platforms, with penalties up to AED 2 million.
• ADGM was the first jurisdiction to regulate carbon credits as environmental instruments, with ACX operating a regulated FSRA-supervised spot exchange and clearing house.
• The most common carbon credit disputes are over non-delivery, double counting, additionality, and project failure, and most ERPAs route disputes to international arbitration.

Who this applies to

The article is for the legal and compliance teams of UAE entities required or expected to register under the National Register for Carbon Credits, including large industrial emitters, energy companies, cement producers, aluminium smelters, petrochemical operators, and large manufacturers above the 0.5 million tCO2e threshold. It also applies to project developers selling credits, traders buying and selling on the secondary market, financial institutions structuring carbon offtake, and ADGM-licensed entities trading on ACX or other regulated venues.

The article does not cover the disclosure side of UAE climate law obligations, including ESG reporting and Climate Law GHG accounting. Those are covered in our ESG enforceability piece and in our ADX, DFM, and ADGM ESG reporting piece.

What counts as a UAE carbon credit

A carbon credit represents one tonne of carbon dioxide equivalent (1 tCO2e) of emission reduction or removal. The reduction has to be:

• Real. The activity took place.
• Additional. The reduction would not have happened without the carbon finance.
• Measurable. The volume can be quantified using accepted methodology.
• Verifiable. An independent third party has confirmed the reduction.
• Permanent. The reduction is not reversed within a defined timeframe.

Each of these five criteria is a frequent battleground. Most carbon disputes globally turn on whether the credits sold met the additionality test, whether the verification was rigorous enough, or whether the reduction was permanent. UAE-issued credits sit on top of the same five criteria. The MRV framework under Cabinet Resolution 67 is built to ensure they are met before approval.

UAE law recognises three categories of carbon credit:

The first is the NRCC-approved credit. This is a credit generated from an approved UAE project, registered on the National Register for Carbon Credits, and approved by the Ministry of Climate Change and Environment.

The second is the Article 6 credit under the Paris Agreement. Article 6.2 governs cooperative approaches between countries (ITMOs, Internationally Transferred Mitigation Outcomes). Article 6.4 sets up the new market mechanism under UN supervision. UAE-issued credits can be authorised for transfer under Article 6 with corresponding adjustments to the UAE's Nationally Determined Contributions.

The third is the voluntary carbon market (VCM) credit. This is a credit issued under a private standard (Verra VCS, Gold Standard, ACR, CAR, Plan Vivo) and traded outside any compliance regime. ADGM regulates these as environmental instruments under FSRA rules, and ACX trades them on a regulated spot basis.

The legal status of each category differs. Compliance credits and voluntary credits are not interchangeable. Buyers using credits to discharge a compliance obligation cannot substitute a voluntary credit unless the regulator accepts it. UAE entities entering into ERPAs or spot trades have to identify which category their counterparty is delivering, and confirm the credit matches the intended use.

Cabinet Resolution 67 of 2024 in operational terms

Cabinet Resolution No. 67 of 2024 establishes the National Register for Carbon Credits (NRCC). The Resolution came into force on 28 December 2024. Compliance was originally required by 28 June 2025. The 30 May 2026 deadline under the parallel Climate Change Law extends the practical compliance horizon for many entities still working through their MRV setup.

The Resolution applies to:

• Entities of Huge Carbon Emissions: any public or private entity emitting 0.5 million tCO2e or more annually from Scope 1 and Scope 2 sources. These entities must register on the NRCC and conduct MRV.
• Participating Entities: entities below the threshold that voluntarily register to generate or trade carbon credits.
• Trading Platforms: regulated platforms that facilitate carbon credit transactions, supervised by the Securities and Commodities Authority (SCA).

The Resolution applies to onshore companies, free zone companies, and financial free zone entities. It does not exclude foreign-owned companies or branches.

The MRV machinery under the Resolution requires:

• Measurement of GHG emissions using approved methodologies aligned with the UAE National System for MRV.
• Reporting to the Ministry of Climate Change and Environment on a defined cycle.
• Verification by an accredited third-party verifier using protocols aligned with international standards.
• Approval of carbon credits by MOCCAE before they can be traded on a regulated platform.

The baseline year for credit approval is 2019. Credits generated from activities since 2019 can be retroactively approved, subject to verification.

Penalties under the Resolution can reach AED 2 million for non-compliance with reporting requirements, failure to align with Paris Agreement obligations, or violations of trading platform rules. The Resolution also provides for suspension of trading rights and licence cancellation.

For entities that are also subject to the Federal Decree-Law 11 of 2024 Climate Change obligations, the two regimes interact. The Climate Law sets the underlying reduction obligation. The NRCC framework provides the trading mechanism by which the obligation can be met through credit purchase.

The ADGM regulated carbon market

ADGM is the first jurisdiction in the world to regulate voluntary carbon credits as financial instruments. The regulatory framework was introduced in September 2022 through an Environmental Instrument classification under FSRA rules. AirCarbon Exchange (ACX) became operational as a Recognised Investment Exchange (RIE) and Recognised Clearing House (RCH) in October 2023.

The ADGM framework treats carbon credits as financial instruments for regulatory purposes. This means:

• The exchange is FSRA-regulated. Trading rules, market surveillance, settlement, and clearing all sit under FSRA supervision.
• Credits trade as spot commodities and as derivatives. ADGM was the first jurisdiction to regulate both spot and derivative carbon contracts.
• Settlement is on a real-time basis with delivery via distributed ledger.
• Multiple international standards are listed, including Verra VCS, Gold Standard, ACR, CAR, and CDM CERs.

The trading parties on ACX include corporates, financial institutions, project developers, and traders. First Abu Dhabi Bank and Helix Climate executed the first trades. Mubadala holds a strategic stake. ADGM-licensed firms trading on the venue need the appropriate FSRA permissions, and most use a regulated commodities broker.

For UAE-onshore entities trading carbon credits through ADGM, the structure typically involves:

• An ADGM-licensed special purpose vehicle or trading subsidiary that holds the trading account.
• A Membership Agreement with ACX that sets out the trading and clearing relationship.
• A counterparty ERPA or spot contract governing the underlying transaction with the project developer or seller.
• Onshore reporting obligations if the underlying entity is also registered on the NRCC or subject to NRCC requirements.

The structure of an ERPA

The Emission Reductions Purchase Agreement (ERPA) is the standard contract between a buyer and seller of carbon credits. The IETA template is the most common starting point. The ERPA addresses:

• Quantity and price of emission reductions to be delivered.
• Delivery and payment schedule across the life of the project or trade.
• Non-delivery consequences if the seller fails to deliver the contracted volume.
• Default consequences if the buyer fails to pay or the seller misrepresents project status.
• Seller obligations: validation, verification, monitoring plan implementation, project operations, registry transfer.
• Buyer obligations: maintaining a registry account, payment, and regulatory communication.

Three commercial structures dominate UAE carbon trade:

• Spot agreements. The seller has already-issued credits and transfers them on payment. Lowest delivery risk. Highest price for the buyer.
• Future delivery agreements. The buyer commits to take credits as they are issued from a project over time. Delivery risk sits with the project. Price discount reflects the risk.
• Forward purchase agreements with upfront payment. The buyer pre-pays for credits to be issued in the future. Used to fund project development. Highest delivery risk. Steepest discount.

The choice of structure is the single biggest determinant of dispute frequency. Spot trades rarely produce ERPA disputes. Forward purchase agreements with upfront payment produce them often.

The price components in a UAE-relevant ERPA usually include:

The most common carbon credit disputes

Carbon credit disputes fall into a small number of recurring patterns. Each pattern produces its own contract, regulatory, and forum response.

Non-delivery. The most common dispute. The seller fails to deliver the contracted volume. Causes include project underperformance, validation failure, verifier disagreement, registry rejection, or host country authorisation delay. The contract usually provides a make-good obligation, with replacement credits sourced from the market at the seller's cost. Where the seller cannot make good, damages run on a market-replacement basis. UAE-law-governed ERPAs apply Article 389 of the Civil Code on damages calculation.

Double counting and double issuance. The same emission reduction is sold twice or counted toward more than one party's obligations. The issue arises in three scenarios. The same credit is sold to two buyers (double sale). The same reduction is registered on two registries (double issuance). The same reduction counts toward both the host country's NDC and a buyer's compliance obligation without corresponding adjustment (double claim). Each scenario produces a different contract remedy. Verra and Gold Standard have arbitration provisions for double issuance disputes seated in London and using ICC or PCA rules.

Additionality challenges. The buyer or a third party (NGO, journalist, regulator) alleges that the project would have happened without carbon finance. If the challenge succeeds, the credits may be invalidated, withdrawn, or marked as non-compliant. The financial loss to the buyer can be material. The contract usually contains seller representations on additionality, with indemnity flow-through.

Permanence failure. The reduction is reversed within the project's permanence period. Forest fires, deforestation, reservoir leakage, and project abandonment all cause permanence failures. Buyer recourse is usually through a buffer pool or a seller make-good obligation, depending on the standard.

Regulatory cancellation or suspension. The host country or the standards body suspends or cancels credits issued from a project. The Ontario cancellation of cap-and-trade in 2018 generated investment arbitration claims under NAFTA. Verra's 2023 to 2024 review of REDD+ credits suspended large volumes from issuance. Regulatory risk on carbon credits is ongoing and material.

Verification disputes. The verifier reaches a different conclusion from the project developer on emission reductions. Verra's template provides for ICC arbitration in London. Gold Standard uses PCA environmental rules. UAE-issued credits will run through the MOCCAE process under Cabinet Resolution 67.

Title and security disputes. Where credits are pledged, transferred, or held in escrow, disputes over title arise. ADGM-regulated trades benefit from real-time settlement on the ACX platform, which reduces title risk. Bilateral ERPAs without registry transfer machinery are higher-risk.

How UAE law treats a carbon credit as property

A central question on every UAE carbon trade is whether the credit is treated as property, a financial instrument, or a contractual right. The answer affects the contract drafting, the registration, the security taking, and the dispute resolution.

In ADGM, the regulatory position is settled. Voluntary carbon credits are environmental instruments under FSRA rules, and tradeable as financial instruments on a regulated venue. Title transfers through the registry mechanism on the exchange. Security can be taken over credits in the same way as over other financial instruments. Disputes are resolved under common law principles applied by ADGM tribunals or under the contractual arbitration clause.

In onshore UAE, the position is less developed. The NRCC framework treats credits as registered units that can be approved and traded. The credit is a contractual entitlement supported by the registry record rather than an unrestricted property right. Transfer happens through the registry. Security taking over onshore-registered credits requires registration of the security interest, ideally with notice to the registry administrator. The Civil Code framework on personal property and registered rights applies, but there is little specific guidance.

The interaction between the two regimes is the practical friction. An NRCC-approved credit is recognised in the UAE for compliance use. A Verra or Gold Standard credit traded on ACX may not be NRCC-approved, and may not be useable to satisfy NRCC compliance obligations without an additional approval step. UAE entities buying credits for NRCC compliance purposes need to verify the credit qualifies before pricing the contract.

Tax treatment of carbon credit transactions

Carbon credit transactions face several UAE tax considerations:

Corporate tax. UAE-onshore entities trading carbon credits realise gains and losses that are subject to the 9 per cent corporate tax regime. Credits held for trading purposes are inventory; credits held for long-term hedging may be financial instruments depending on accounting treatment. The classification affects timing of recognition.

Free zone qualifying income. ADGM and other free zone entities trading carbon credits may benefit from the 0 per cent qualifying income rate if the activity falls within the qualifying activities list and the entity meets the substance requirements. Carbon trading activity has not been specifically listed, so the position depends on the broader category of treasury and financing or commodity trading activities.

VAT. Carbon credits are zero-rated in some jurisdictions and standard-rated in others. The UAE FTA position on carbon credit VAT treatment has been under active discussion. Cross-border carbon trades to non-UAE buyers should generally qualify as zero-rated exports. Domestic UAE-to-UAE carbon trades are at risk of being treated as standard-rated supplies.

Withholding tax. The UAE does not currently impose withholding tax on cross-border carbon credit payments, but this position is subject to the corporate tax regime's evolving treatment of cross-border services and royalties.

The tax position on carbon credit transactions is one of the few areas where UAE practice is still developing. ERPAs entering into long-term forward arrangements should include tax change-in-law provisions to allocate risk for future regulatory changes.

Forum and governing law

UAE carbon credit transactions use a mix of forums depending on the trade structure and the parties:

• ACX-traded spot transactions: governed by ACX rules, with disputes resolved under ADGM-seated arbitration or, for membership and rule disputes, before the FSRA.
• Bilateral ERPAs with international buyers: typically English law with London-seated LCIA or ICC arbitration. Predictable, with developed case law on commodity contract disputes.
• Bilateral ERPAs with UAE buyers: increasingly UAE law with DIAC-seated arbitration in Dubai or ArbitrateAD-seated arbitration in Abu Dhabi.
• Disputes with verifiers: under the standards body rules. Verra uses ICC London arbitration. Gold Standard uses PCA environmental rules.
• Regulatory disputes with MOCCAE or the SCA: through UAE administrative review processes, with judicial review available before UAE courts.

The choice of forum has direct consequences for evidence, expert appointment, and remedies. Carbon disputes involve climate science, satellite data, project documentation, and verifier reports. Tribunals with environmental expertise (PCA, Gold Standard panels) are better placed to handle the technical evidence than commercial commodity tribunals. Parties drafting ERPAs should consider whether the standard commercial arbitration clause is appropriate or whether a specialist environmental arbitration clause produces better outcomes.

Drafting a UAE-relevant ERPA

UAE entities entering into ERPAs as buyer or seller should ensure the contract addresses:

• Credit specification: standard, vintage, project type, project ID, and registry of issuance. Generic specifications produce delivery disputes.
• Article 6 authorisation status: whether the credit is authorised for international transfer with corresponding adjustment, and who bears the risk of authorisation failure.
• NRCC compatibility: whether the credit qualifies for NRCC compliance use, and what happens if NRCC approval is withdrawn or modified.
• Delivery mechanism: registry transfer, escrow arrangement, settlement timing, and cure periods.
• Make-good obligations: replacement credits, market-priced damages, or buyer election remedies.
• Representations and warranties: project status, additionality, baseline methodology, validation, verification, no double counting.
• Permanence and reversal protection: buffer pool reliance, replacement obligations, insurance.
• Tax allocation: who bears VAT, withholding tax, and tax change-in-law risk.
• Confidentiality: project documentation is often commercially sensitive.
• Force majeure: distinguishing between project-side events and counterparty events.
• Dispute resolution: forum, seat, governing law, and emergency relief mechanism.

A well-drafted ERPA addresses each of these explicitly. A boilerplate ERPA copied from a non-UAE template often fails on Article 6 authorisation, NRCC compatibility, and tax allocation, which are the three UAE-specific points.

Common transaction failures and how to avoid them

UAE carbon credit transactions fail in litigation for a small number of recurring reasons:

• Mismatch between credit type and intended use. The buyer needed an NRCC-compliant credit. The seller delivered a Verra credit not approved by MOCCAE. The credit is not useable for compliance.
• Article 6 authorisation gaps. The credit is sold as Article 6-authorised but the host country has not in fact issued the corresponding adjustment.
• Project failure not covered. The seller's project fails post-signature but pre-issuance, and the contract does not allocate the loss clearly.
• Registry transfer failure. Settlement runs across two incompatible registries, and the title transfer does not complete.
• Validation or verification challenged after signing. A third party challenges the project's validation status mid-life, and the contract does not address how the parties manage the credits during the challenge.
• Cancellation of credits by the standards body. Verra suspends credits across a methodology, and existing buyers face write-downs. The contract does not address allocation of cancellation losses.

Each is addressable in drafting. The drafting choices are the single most important compliance step a UAE entity can take ahead of the 30 May 2026 deadline.

How should UAE entities approach carbon credit transactions in 2026?

The UAE carbon market is moving from setup phase to compliance phase across 2026. Entities of Huge Carbon Emissions are working through MRV implementation, NRCC registration, and credit procurement decisions in parallel. Project developers are choosing between domestic NRCC registration and international voluntary market routes. Traders on ACX are scaling activity. Each pathway produces different contract risk and different dispute exposure.

The transactions that hold up are the ones structured against the right framework from the start, with the credit type, the registration, the contract terms, and the forum all aligned to the buyer's intended use. The transactions that fail in litigation almost always do so because one of the four was misaligned at signature.

For UAE emitters, project developers, traders, and financial institutions structuring carbon credit transactions, our carbon markets and energy team advises on ERPA drafting, NRCC registration, ADGM trading structure, and dispute resolution. The work is most useful before the contract is signed, when the alignment between credit type, registration, and intended use can still be addressed.
