GHG Protocol vs ISO 14064 for UAE Climate Law Compliance

Educational practitioner guidance. Not legal advice. Verify current official requirements and entity-specific regulator correspondence before acting.

The first question is not which standard is more recognised. It is which criteria govern the intended statement. An Article 6 filing, a Resolution 67 registry report, an emirate programme, a free-zone instruction, an IFRS S2 disclosure and a voluntary carbon inventory can use related source data while applying different criteria.

Figure 2. GHG Protocol and ISO 14064-1 can both support a strong inventory, but neither replaces the UAE authority's accepted criterion.

GHG Protocol requires an organisation to select and apply a consolidation approach. That makes it useful for groups with subsidiaries, joint operations, leases and contractors. A UAE legal instruction may nevertheless name a facility or Source that cuts across the chosen corporate boundary. ISO 14064-1 can also support a documented organisation and reporting boundary, but the programme criteria remain additional.

The most resilient architecture stores the activity and evidence once, then classifies it under the chosen method and legal output. Every source record should keep the equipment or activity, gas, ownership/control facts, unit, period, method candidate, factor version, estimate flag, evidence and reviewer. Final Scope or ISO category labels should be generated through controlled rules rather than entered as irreversible text.

A well-labelled workbook is not necessarily verification-ready. The inventory should contain a methodology memorandum, boundary register, source register, factor and GWP register, calculation files, estimate log, base-year and recalculation policy, quality controls, evidence register, change log, management representations and release record. The exact package should be tailored to the authority and verifier criteria.

Minimum method-selection memorandum

The inventory standard explains what the GHG statement contains and how it was prepared. The verification criteria govern how an independent party plans, tests and concludes on that statement. ISO 14064-3 is designed for verification and validation of organisation, project and product GHG statements. A verifier may also need accreditation, programme approval, sector competence, independence and a defined scope under UAE requirements.

1. Create a legal and authority source register: instrument, designation, Source, reporting period, required form, method, factors, verifier and retention.

2. Choose a provisional inventory architecture that preserves source-level facts and can map to both GHG Protocol and ISO 14064-1 concepts.

3. Document the organisational and facility boundary with alternative views where the legal perimeter remains uncertain.

4. Build complete Scope 1 and purchased-energy source registers; screen Scope 3 and removals without assuming they are required in the current legal output.

5. Version factors, GWPs, methods, estimates, base-year rules and recalculations so they can be changed without destroying source lineage.

6. Run a verification-readiness review against the likely criteria and identify evidence, independence and competence gaps.

7. Send a focused confirmation request to the competent authority or programme administrator, attaching the proposed method and boundary questions.

8. Freeze and approve the filing view only after the accepted criteria are confirmed; retain the provisional-to-final bridge.

The group does not call the provisional inventory legally compliant. Its method memorandum identifies pending questions on facility aggregation, district-cooling factors, refrigerant treatment and verifier approval. Once the authority answers, the group updates the output rules, records the version change and retains the original parent-reporting view.

Selecting a standard before identifying the legal statement and authority criteria.

Treating GHG Protocol Scopes as automatically identical to every ISO or UAE category.

Using a corporate control boundary when a facility-specific legal perimeter is required.

Failing to store raw activity data because the calculation tool produces a total.

Using market claims, offsets or removals to reduce gross inventory figures without accepted rules.

Omitting estimate, uncertainty and factor-version records.

Confusing ISO 14064-1 inventory preparation with ISO 14064-3 verification or with accreditation.

Naming a draft revision as the current standard or failing to monitor GHG Protocol revisions.

Making a compliance claim before the authority accepts the method and filing scope.
