Saudi Carbon Monitoring provides activity data and emission factor controls in Saudi Arabia, helping organisations build a controlled calculation workflow for review by a qualified GHG practitioner. Most inventory values combine an activity quantity with an emission factor or engineering relationship; the arithmetic may be simple, but a wrong unit, outdated factor, duplicated record or undocumented assumption can materially change the answer.

We scope, coordinate and manage this work; formal GHG accounting, factor selection and verification are delivered by qualified parties. The service does not select factors universally or issue a verified footprint, because factor suitability depends on the reporting framework, geography, technology, fuel or material, greenhouse gases, period and intended use.
Define activity data in operational terms
Each data field should have a name, definition, unit, source, owner, frequency, boundary and evidence route. “Fuel use” is too vague if it does not state fuel type, quantity basis, density or conversion, site, asset and period. “Production” needs product and measurement basis. The data dictionary should preserve the original unit and document every conversion.
Reconciliation is a practical control. Fuel issues can be compared with purchases and stock movements; electricity can be compared with account totals; production can be compared with approved operational reports. Differences need investigation or explanation, not automatic adjustment.
Activity data and emission factor controls in Saudi Arabia: the factor register
For every factor, record:
- the publisher, source document or URL, and the table or section;
- version date, geography and technology;
- unit and gas coverage;
- heating-value basis where relevant;
- oxidation or conversion assumptions;
- the global-warming-potential basis.
Save the source evidence allowed by its terms and retain enough citation detail for another practitioner to locate it.
US EPA AP-42 is a compilation of air-pollutant factors for stationary sources and is not a universal GHG factor library. IPCC guidance supports national inventory methods. GHG Protocol offers corporate standards and tools. The practitioner must select the source suited to the calculation rather than mixing documents because they are familiar.
Control formulas and changes
Calculation workbooks or software should separate raw imports, transformations, factors, formulas and outputs. Protect formulas, flag hard-coded overrides and require review. Automated scripts need version control and test cases; manual spreadsheets need cell protection, checksums or equivalent controls and a change log.
When a factor or method changes, document whether the change affects only the current period or requires base-year recalculation under the chosen framework. Do not silently overwrite the prior result. The carbon dashboards and audit trails page addresses controlled presentation and records.
Treat uncertainty honestly
Precision in a spreadsheet does not equal certainty. Record measurement accuracy, sampling representativeness, estimation method, factor quality and missing coverage. Data Gaps, Estimation and Measurement Uncertainty provides a structured assessment. The qualified GHG practitioner decides whether quantitative or qualitative uncertainty is needed.
Deliverables
The work can produce a data dictionary, unit-conversion table, factor register, calculation-control standard, review checklist, change log, exception report and reproducible calculation package. For scoping, provide current workbooks or platform exports, factor sources, reporting framework, site and source list, prior-year methods, known overrides and verification comments. Saudi Carbon Monitoring is available for projects across Saudi Arabia, including Dammam, Jubail, Riyadh, Jeddah, NEOM and Qiddiya.
Calculation review tests
Run unit tests on representative records and check:
- litres, kilograms, normal cubic metres, energy units and currencies convert as intended;
- formula ranges at the first and last record;
- new sites are included;
- no hard-coded constants sit outside the factor register.
Then recalculate a sample independently and compare results. Use reasonableness checks against fuel, production or prior periods without automatically rejecting genuine changes.
For every issued result, retain a calculation manifest identifying input versions, factor-register version, code or workbook version, run date and approvers. If a correction is needed, issue a new version and explain which totals, KPIs and disclosures changed. A verifier should be able to reproduce a sample without reverse-engineering undocumented formulas. These controls are simple enough for spreadsheets and scalable to software; the technology changes, but provenance and approval remain essential.
Keep the method readable
Alongside the calculation file, maintain a concise methodology note that explains boundaries, equations, factor hierarchy, units, estimates, rounding and approvals in plain language. Update it when the calculation changes. This document helps operations, management and future practitioners understand the result without exposing them to every workbook detail and reduces dependence on one preparer’s memory.
Frequently asked questions
Who provides activity data and emission factor controls in Saudi Arabia?
Saudi Carbon Monitoring provides the controlled calculation workflow: the data dictionary, factor register, calculation-control standard and review checklist. The GHG practitioner who approves the methodology and any verification are separate, qualified parties we coordinate with.
How do I choose an emission factor, and can one factor serve every Saudi facility?
Not automatically. Geography, fuel or technology, units, time period and reporting method can differ, so suitability must be reviewed. A newer factor is not always better: it should be current and appropriate, but methodology consistency and base-year policies also matter.
Should original units be overwritten after conversion?
No. Retain the original value and unit, then show the controlled conversion and resulting unit.
How are manual overrides handled?
Limit access, require a reason and approval, preserve the prior value and include the change in the audit trail.
Who approves the calculation methodology?
The named qualified GHG practitioner and the organisation’s authorised governance role approve it; the verifier remains independent.
What affects the cost of calculation controls?
Cost depends on the number of sites and sources, the state of current workbooks or platform exports, the number of factor sources to document, and the review and reporting requirements. Your quotation sets out the scope and price.
How long does it take to set up calculation controls?
Timing depends on the volume and quality of existing records, the number of sources and sites, and how many review rounds are needed. The schedule is set out in your quotation.
