Is There a UAE Climate Law Emissions Threshold? Article 6 vs the 0.5 Million tCO2e Registry Test

A practitioner guide to preventing one of the most consequential UAE climate-reporting errors: moving a threshold from one instrument, scope or organisational level into another.

A search for “the UAE climate threshold” usually combines several legal questions. The federal Climate Law defines its broad scope by the existence of an emitting Source. Article 6 then uses an authority determination rather than a number. Cabinet Resolution No. 67 of 2024 uses a numerical test for a separate National Carbon Credit Registry regime. Local and facility schemes may add their own thresholds, sectors and organisational levels.

A company can therefore be below 0.5 million tCO2e and still need to assess the federal law, an Article 6 instruction, a local facility scheme or an environmental permit. Conversely, a company that exceeds 0.5 million tCO2e should not assume that registry registration is the only relevant climate reporting duty.

Figure 1. Federal scope, Article 6 designation, the Resolution 67 registry threshold and local schemes are distinct trigger layers.

Article 3 applies the Decree-Law to Sources in the State, including free zones. A Source is a public or private legal person, or an individual enterprise, whose operations or activities release greenhouse gases. No numerical emissions amount appears in that scope clause. The broad reach is relevant to mitigation, climate data and other provisions, but it should not be translated automatically into an identical filing event for every Source.

Article 6(1) applies its detailed MRV duties to Sources determined by MOCCAE and the competent authority, in coordination with the entity concerned. The article does not specify “25,000 tCO2e”, “0.5 million tCO2e” or any other universal numerical designation threshold. The practical trigger may be communicated through an implementing resolution, authority list, registration request, portal invitation, permit, sector rule or written instruction.

Cabinet Resolution No. 67 of 2024 defines an entity of huge carbon emissions by annual emissions of at least 0.5 million metric tonnes CO2e. Article 3 makes the Resolution applicable across the UAE, including financial and non-financial free zones, and states that registration is mandatory for entities at or above the threshold within Scope 1 and Scope 2. Entities below the threshold may participate voluntarily.

The calculation must therefore preserve the Resolution’s own organisational and emissions boundary. The practitioner should record the legal entity or other organisational unit tested, the reporting year, Scope 1 and Scope 2 coverage, gases and CO2e conversion, consolidations, acquisitions and disposals, data quality and the source of the current threshold. Do not mix Scope 3 into the threshold merely because Scope 3 appears elsewhere in a corporate inventory or reporting form.

A local scheme can use a threshold that tests a different object. Abu Dhabi facility MRV materials use a facility-level direct-emissions test of 25,000 tCO2e for covered sectors in the current implementation materials, and the guidance states that the local scheme operates without prejudice to the federal Climate Law and Resolution 67. The 25,000 test is not the federal Article 6 threshold, and the 0.5 million entity-level Scope 1 and Scope 2 test is not the Abu Dhabi facility threshold.

Other local, permit or sector requirements may use no threshold, a capacity test, an activity test, a listed-sector test or a regulator designation. The source-control method is the same: identify the instrument, authority, organisational level, facility/entity, scopes, gases, period, threshold, sector and current version.

Figure 2. The same emissions amount can produce different conclusions because the instruments test different entities, facilities, scopes and triggers.

A threshold should never be copied into a policy, calculator or board paper without its legal attributes. The number alone is not the rule. “0.5 million tCO2e” is incomplete unless the record says which Resolution, which entity, which annual period, which scopes, which gases, which authority and which version. “25,000 tCO2e” is incomplete unless it states that the example is an Abu Dhabi facility-level direct-emissions test for covered sectors under current guidance.

Use the most current complete reporting period and a controlled organisational boundary.

Reconcile material sources, units, factors, acquisitions, disposals and electricity data.

Quantify uncertainty and the effect of unresolved data gaps; do not use optimistic rounding to remain below the threshold.

Perform a sensitivity analysis for material estimates and factor changes.

Ask the authority how the threshold is applied where the entity, branch or consolidation boundary is unclear.

Prepare registration and MRV readiness before the threshold is crossed, especially where growth or acquisition is expected.

Approve the conclusion and monitoring frequency through management or board governance.

Set an early-warning trigger so that monthly or quarterly data can identify a likely crossing before year-end.

Resolution 67 permits entities below the mandatory threshold to participate voluntarily in the registry. Voluntary participation is not the same as a legal exemption from other duties, and it should not be presented as automatic access to every carbon-credit benefit. The entity should define the business purpose, organisational boundary, monitoring and verification requirements, cost, governance, carbon-credit ownership, claims and exit implications.
