What is measurement, reporting, and verification (MRV)?
MRV is a linked set of controls, not one calculation. Measurement fixes the reporting period, the sites and activities covered, the source records, the units, and the calculation method. Reporting places the result and required explanations in the named form by its deadline. Verification compares that submission with the stated method and underlying records, then documents findings and corrections.
In the UAE, Federal Decree-Law No. 11 of 2024 Article 6 requires sources selected by the Ministry and local authority to measure emissions regularly, prepare an inventory, file periodic reports, submit activity and reduction data, and keep measured-emissions records for five years. Article 6(3) assigns the data-accuracy check to the Ministry or local authority. Location in the UAE, including a free zone, does not by itself show that a source has been selected. Check the implementing decision through the UAE requirements guide.
Vietnam's current consolidated Decree 06 defines MRV for greenhouse gas reductions in Article 3(7). Articles 9 and 10 require the national system and specify measurement methods, operational data, emission factors, technical actions, management actions, and reduction results. Under Article 10(3)(a), an establishment covered by Article 5(1) submits the previous year's Form 02 report to its provincial authority by 31 March each year from 2027. The Vietnam requirements guide explains the facility test.
Why does MRV matter to you?
Your result must survive a check against the exact rule or request. A missing site, an unexplained factor change, or an overwritten workbook can break the chain from meter or invoice to submitted total. The UAE rule can require five years of measured-emissions records. Vietnam Article 10(1)(b) expects the report itself to identify the method, operational data, factor, actions, and result.
How does MRV work?
- Translate the requirement: record the article or contract clause, covered facility, period, unit, form, deadline, and reviewer.
- Measure: create a versioned register linking every reported line to a meter export, invoice, production log, factor, formula, and data owner.
- Report: reconcile the register to the required form, explain gaps and estimates, capture approval, and save the filed version and receipt.
- Verify: use the reviewer named by the rule, test records and calculations, record each finding, and retain the corrected file without erasing the first submission.
What mistakes should you avoid?
- Calling an emissions inventory complete MRV when no submission form, deadline, or verification record exists.
- Keeping a total without the source unit, factor version, formula, reporting period, and facility name.
- Replacing a rejected file instead of preserving the finding, correction, approval, and resubmission receipt.
- Applying UAE or Vietnam duties to an overseas site without first passing the law's location and facility tests.
Is MRV the same as GHG verification?
No. Verification is the checking stage. MRV also covers the approved measurement method, the data trail, the prescribed report, and the submission deadline. A verification opinion alone does not prove that the correct Form 02 or Article 6 record set was filed.
Does every company need an MRV system?
No. Start with the legal provision, customer clause, funding agreement, or programme rule that asks for it. For UAE Article 6, confirm that the relevant authority has selected the source. For Vietnam, test the establishment against Article 5(1) before using the 31 March reporting timetable.
What should you provide for an MRV check?
Provide the requirement, boundary and period note, source register, original meter or invoice files, calculation workbook, method and factor record, signed submission, receipt, findings log, corrections, and final approval. Label every version and show which file was actually submitted.
