GHG Inventory Verification Preparation Saudi Arabia

This GHG inventory verification checklist helps organisations in Saudi Arabia, with support from Saudi Carbon Monitoring, organise boundaries, methods, source evidence, calculations and management approvals before an independent verifier begins. Independent verification is not a final proofreading step: the verifier examines whether the GHG statement is supported by criteria, evidence and controls, so preparation should begin while data owners can still retrieve records and explain changes.

You receive a written readiness plan setting out the evidence index, boundary file, gap log, scope and price. Request a quotation

The reporting framework, assurance engagement and verifier competence remain specific to the organisation and appointment. Readiness support does not replace independent verification: the verifier alone determines the conclusion, and nobody can promise or manufacture a preferred one.

GHG inventory verification checklist: confirm criteria and scope

Document the reporting framework, organisational and operational boundaries, period, base year, greenhouse gases, calculation methods, factor sources, materiality and intended level of assurance. The independent verifier confirms its own engagement criteria and procedures.

If the organisation used external support to prepare the inventory, state that role clearly. Preparation and independent verification should not be presented as the same service.

Create a boundary and change file

Retain legal entity and facility lists, consolidation decisions, acquisitions, disposals, expansions, closures and methodology changes. Explain exclusions. If prior periods or the base year were recalculated, show why and how.

Build an evidence index

For every material total, link the reported value to calculation, factors, activity data and source documents. Evidence may include invoices, meter exports, production reports, refrigerant logs, source tests, LDAR records, supplier submissions and contracts. Record owner, period, version and location.

Keep raw and processed data. A verifier may need to see how imports, conversions and manual adjustments changed the value. Secure access and confidentiality can be managed without losing traceability.

Reproduce sample calculations

Select several sites and source categories. Start with the report and trace backward to source, then recalculate forward. Check units, factors, formula ranges, duplicates, missing periods, approvals and consistency with the method. Reconcile against finance or operations where appropriate.

Resolve or disclose gaps

Maintain a gap and estimate log with significance, method, owner and improvement plan. Do not hide unresolved issues. Management should decide whether to correct, disclose or accept a limitation before the verifier reports.

Manage requests and corrections

Use one request tracker with owner, due date, evidence supplied and status. When a correction is made, preserve the old value, reason, approval and affected outputs. Update totals consistently and notify the verifier.

The verification-readiness service can organise these controls.

Run a readiness meeting by source category

Bring data owners, the inventory preparer and governance lead together. Review these categories in turn:

• combustion
• process
• fugitive
• refrigerant
• purchased energy
• material Scope 3 categories

For each, confirm source systems, evidence location, estimates, reviewer and open issue. Give high-risk items a responsible owner and closure date.

Then test the request process. Ask someone unfamiliar with the workbook to retrieve and reproduce selected values using only the index and method notes. Record where file names, permissions, units or factor citations fail. Correct the system, not just the sampled number.

Protect verifier independence

The organisation can prepare clear explanations and retrieve evidence promptly, but it should not ask the verifier to design the inventory it will assure. Agree secure access and a request tracker. Keep all corrections visible and reissue affected totals through approval. If the verifier identifies a limitation, management decides how to correct or disclose it. We coordinate responses and evidence retrieval; the conclusion remains the verifier’s.

Prepare the management representation process

The verifier may request representations from management about responsibility, completeness or disclosed matters. The exact wording belongs to the verifier and applicable engagement. Internally, make sure authorised management understands the boundary, significant estimates, changes, uncorrected items and controls before it signs anything.

Hold a closing-readiness review with preparers and data owners. Confirm that all corrections have flowed through tables, narrative and evidence indexes. Lock the submitted version and record the date. If new information emerges, use the agreed change process and notify the verifier rather than maintaining an unofficial parallel result.

Verification readiness is complete when the organisation can explain and evidence its inventory—not when a folder merely contains many files.

Use one controlled contact for verifier requests so site teams do not send inconsistent working files. Every response should reference the evidence index and issued inventory version. This simple discipline protects confidentiality, reduces duplication and keeps corrections visible across the engagement.
