Choosing a GHG Verifier for Abu Dhabi Facility MRV

Introduction

For facilities in Abu Dhabi that emit 25,000 tCO2e or more of Scope 1 emissions a year, the emissions report is about to need a second signature. Under EAD’s facility-level MRV system, independent verification becomes mandatory from 2027 onwards, starting with Reporting Year 2026. The verified report for 2026 is due to EAD by 31 March 2027.

Appointing the verifier is not a formality to leave for the first quarter of 2027. EAD’s Technical Guidance for Facility Level MRV of Greenhouse Gas Emissions in Abu Dhabi Emirate (issued 27 February 2026, Doc ID EAD-IEPP, Rev. 02) sets rules on who may verify, how independent they must be, how long they may stay, and when they must start. Two of those rules bite during the reporting year itself, not after it.

Who counts as an accredited verifier

The guidance defines an accredited verifier as an independent third party legal entity authorised by EAD to carry out verification. There are two ways onto that footing.

1. EAD’s own list. EAD will issue an annual list of accredited verifiers. A verifier applies to EAD and provides satisfactory evidence of the required certifications.
2. MOCCAE’s list. Verifiers that are not accredited under EAD’s process but appear on the list of verification agencies issued by MOCCAE under Cabinet Resolution 67 of 2024 are deemed accredited for Abu Dhabi purposes. That resolution established the UAE National Register for Carbon Credits.

What the guidance means by accreditation is accreditation for the scope of GHG verification under ISO 14065, applying ISO 14064-3 to the verification itself, with ISO 14064-1, ISO 14064-2 and, where required, ISO 14067 within scope. The verification section also names ISO/IEC 17029.

The guidance’s wording speaks of accreditation from the International Organization for Standardization. Read that as shorthand. ISO publishes the standards; it does not accredit anyone. Accreditation is granted by an accreditation body, which assesses a verification body against ISO 14065, the environmental information application of ISO/IEC 17029. In the UAE, the Emirates International Accreditation Centre (EIAC) operates accreditation of validation and verification bodies against ISO/IEC 17029.

Reasonable assurance, not limited

The guidance sets the level plainly. The verifier must gather sufficient information and evidence to issue a verification report with reasonable assurance, and the stated objective is to conclude with a high degree of certainty that the reported data are free from inconsistencies and were collected according to the monitoring methodology EAD approved.

Most corporate sustainability reports that carry assurance at all carry limited assurance: fewer procedures and a negatively worded conclusion that nothing has come to the assurer’s attention. Reasonable assurance is a positive opinion, and the testing has to be deep enough to support it. Expect the verifier to trace meter readings and invoices through to the reported figure, recalculate the emissions, check calibration records and fuel analyses, and test the controls in the monitoring plan. The two levels are compared in our guide to assurance standards.

The guidance puts a matching duty on the operator: to enable reasonable assurance, and to document monitoring data so that the verifier and EAD can reproduce the emissions calculation. An evidence file that carried a limited assurance review of the group report will not automatically carry a reasonable assurance opinion.

Verification covers more than the annual number. The guidance requires a thorough review of the monitoring plan, the methodologies, the emissions data and the supporting documentation, and it states that the monitoring plan itself is subject to an external audit by an accredited verifier, with the audit report submitted to EAD alongside the plan.

Independence: the firm that built your inventory cannot verify it

The guidance requires the verifier to be independent from the operator and impartial. The verifier, and any part of the same legal entity, must not be an operator, the owner of an operator, or owned by one, and must have no relationship with the operator that could affect its independence and impartiality.

The practical consequence is simple. The guidance allows an operator to prepare its emissions report in-house or with an external consultant. Whichever firm builds the monitoring plan, populates EAD’s template and assembles the evidence is on the operator’s side of the line, and cannot then verify the result. ISO/IEC 17029 adds a second layer inside the verification body: the review of the verification and the decision to issue the opinion must be made by someone who did not carry out the verification.

“

Decide who prepares and who verifies before either engagement starts. Unpicking a conflict after the work is done costs a reporting year.

Rotation. An accredited verifier may not verify the same facility for more than six consecutive years, and must then take a two consecutive year break. The first rotation falls in the early 2030s, but it matters now: a new verifier will start from your files, not its predecessor’s memory, so the documentation has to stand on its own.

The timing rules, and what they mean for Reporting Year 2026

The guidance sets four timing points for verification.

• The verifier must determine the time allocation needed for each engagement.
• Verification activities should begin during the year being reported on, rather than after it has ended, and no later than the middle of that year.
• The verifier must conduct a site visit at one or more appropriate times during the process.
• By no later than 1 July of each reporting year, the verifier must notify EAD of its planned verifications.

The operator then submits the verified emissions report, with the verification report, by 31 March of the following year.

Reporting year	Verifier notifies EAD by	Verification work begins by	Verified report to EAD by
2026	1 July 2026	Mid-2026	31 March 2027
2027	1 July 2027	Mid-2027	31 March 2028

For Reporting Year 2026, read the dates exactly as they stand. The guidance, issued in February 2026, says the appointment of an accredited verifier is not obligatory until 2027. EAD’s portal says verification is mandatory from 2027 onwards, starting with Reporting Year 2026. On the guidance’s in-year timing rules, the 1 July 2026 notification and the mid-2026 start for that year have already passed. The guidance does not say how those two dates apply to the first mandatory year, and its FAQ notes that work is under way to make accredited verifiers available for future reporting cycles.

That gap should not be filled with an assumption. An operator in scope with no verifier for 2026 should appoint one now, ask EAD in writing how the 1 July notification applies to Reporting Year 2026, and keep the reply on file.

For Reporting Year 2027 there is no ambiguity. The verifier must notify EAD by 1 July 2027 and be at work by mid-2027, so the appointment belongs in the first quarter of 2027, while the 2026 verification is running. Appoint once for both years.

New facilities

A facility that commenced operations within the 24 months preceding the end of the reporting period is a new facility under the guidance. A new facility meeting the threshold is exempt from verification for reporting periods during its first year of operation, and must submit a verified emissions report in its third year of operation, covering the second year’s emissions with any adjustments needed. To qualify, the operator must notify EAD of the operational start date within 90 days of commencing operations.

The exemption covers verification only: monitoring continues and unverified data must still be submitted. EAD can revoke it for significant non-compliance with the monitoring requirements.

What this verification does not do

It does not satisfy CBAM. EAD’s FAQ states that participation in the Abu Dhabi MRV programme does not currently exempt facilities from Carbon Border Adjustment Mechanism reporting obligations, and that exporters to the EU must comply with CBAM independently. No recognition between the two is in place. See CBAM for GCC aluminium and steel exporters.

It is not the federal route. Facilities physically located in Abu Dhabi do not report separately to MOCCAE. EAD is the sole point of contact, and all submissions go through the Facility Level MRV Reporting Portal at facilitymrv.ead.ae.

It is not approval as an environmental consultancy office. EAD’s annual environmental data report must be prepared by an office approved under EAD Resolution No. (4) of 2025, which requires a physical headquarters with a valid licence in the emirate. The MRV verifier route turns on accreditation, or a place on MOCCAE’s list. Neither status implies the other. The two regimes are compared in our Abu Dhabi environmental compliance guide.

What is still to be issued

The guidance assigns three instruments to the Chairman of EAD’s Board of Directors:

1. The criteria on which accredited verifiers are authorised and listed.
2. A schedule of violations and administrative fines, with appeal mechanisms.
3. Processes for resolving disputes between operators and verifiers or other stakeholders.

At the date of writing, none of the three has been published. EAD announced Resolution No. (03) of 2026 in September 2026, establishing the verification framework and verifier registration and accreditation; the operational detail available today is in the guidance, which already provides:

• Discrepancies. Where the operator’s data and the verifier’s findings differ, the operator resolves the discrepancy in consultation with the verifier and submits a revised report within 30 days of the verifier’s notification.
• Disputes. If operator and verifier disagree on the emissions data or the monitoring plan, the operator may ask EAD to review. EAD decides within 60 days, and the decision is final and binding.
• Corrections. Errors and omissions are corrected within 30 days of discovery, and corrections are retained for at least five years.
• Enforcement. The guidance points to penalties under Article 15 of Federal Decree-Law No. 11 of 2024, which sets fines of AED 50,000 to AED 2,000,000 for breaches of Article 6(1), and to administrative penalties under Article 17. EAD may also take further action under applicable legislation, including temporary suspension of facility operations until compliance is shown.

Questions to ask a prospective verifier

Put these in writing and keep the answers with the engagement letter.

1. Are you on EAD’s list of accredited verifiers, or on MOCCAE’s list under Cabinet Resolution 67 of 2024? Show us the entry.
2. Which accreditation body accredited you, against which standard, and does your scope schedule cover GHG verification to ISO 14064-3 for our sector and our emission sources?
3. Has your firm, or any part of the same legal entity, prepared our monitoring plan, our emissions report or our inventory, or provided us with any other service that touches this data? Is there any ownership link either way?
4. How many consecutive years have you verified this facility? Relevant from the first engagement, because the six-year clock starts then.
5. When will you notify EAD of the engagement, and when will fieldwork and the site visit take place? The answer should sit inside the reporting year.
6. What time allocation have you estimated, and on what basis? The guidance requires you to set one per engagement.
7. Who is on the team, and what is their experience with our source streams, for example combustion, process emissions or methane?
8. Who carries out the independent review and makes the decision on the opinion? It must be someone outside the verification team.
9. What materiality threshold will you apply, and how will you treat data gaps and estimates?
10. What will you need from us, and when? Expect the monitoring plan, the site diagram, meter and calibration records, invoices, fuel analyses and the completed EAD template.
11. How will you handle discrepancies within the 30-day window, and how will you record recommendations? The operator must act on them in later years.
12. Is this engagement limited to EAD MRV? CBAM verification and assurance on a group sustainability report are separate engagements.

How ESGweise helps

Because the firm that prepares the data cannot verify it, ESGweise works on the operator’s side of that line for facility MRV. We build and document the GHG inventory and monitoring plan, populate EAD’s template, set up the meter register, calibration records and evidence trail a verifier will test, and run a verification readiness review before the accredited verifier arrives. We also help operators shortlist verifiers against the questions above.

Separately, we provide independent assurance under ISAE 3000 and ISO 14064-3 on corporate sustainability and GHG reporting, where we have not prepared the information being assured. Where EAD requires an accredited verifier, the facility needs one; our work is the data and evidence behind it. For the data itself, see one year of energy data, four obligations.

Conclusion

The verifier decision for Abu Dhabi facility MRV is constrained from four directions: the firm must be accredited or on MOCCAE’s list, it must be independent of whoever prepared the data, it must deliver reasonable assurance, and it must be engaged early enough to notify EAD by 1 July and start work by mid-year. For Reporting Year 2026 those in-year dates have already passed, and the guidance is silent on how they apply to the first mandatory year, so appoint now and get EAD’s answer in writing. For 2027 the calendar is fixed: the appointment belongs in the first quarter.
