Facility Emissions Inventory Data in Saudi Arabia

Saudi Carbon Monitoring supports facility emissions inventory data planning in Saudi Arabia, helping facilities identify the source, activity and measurement data an inventory needs. We scope and coordinate the data work, with the evidence scope set for the relevant facility, reporting purpose and approved method. A useful emissions inventory is built from a source map, operating data and defensible methods, not from a single questionnaire.

The exact data depend on whether the inventory covers air pollutants, greenhouse gases, permit reporting, corporate accounting or an impact study. Start by writing the purpose, period and intended users. Data planning does not replace the permit, approved method or regulatory decision that applies to your facility.

Facility and boundary information

Collect the facility description, legal and operational entities, plot plans, process-flow diagrams, production units, utilities, operating schedule and reporting period. Note expansions, shutdowns, ownership changes and temporary activities. For a corporate GHG inventory, a qualified practitioner must approve the organisational and operational boundaries.

A complete source register

List stacks, vents, combustion equipment, generators, turbines, heaters, process units, flares, storage, loading, wastewater, tanks, material handling, mobile equipment, refrigerants and fugitive components as relevant. Give each source a unique identifier, location, process owner, operating state and pollutant or greenhouse-gas potential.

Walkdowns are often needed to reconcile drawings with the installed plant. Document inaccessible, inactive and newly commissioned sources rather than omitting them.

Activity and operating data for an emissions inventory

Depending on the source, collect fuel quantity and properties, feed and production, operating hours, flow, composition, process chemistry, control-device status, flare activity, refrigerant movement, component counts, vehicle fuel and other drivers. Preserve original units and time periods.

Align activity data with any measurement:

• A stack result needs the load, fuel and control status during the run.
• A leak survey needs the component population and operating status.
• A flare sample needs flow, composition and event context.

Measurement and estimation evidence

Gather source-test reports, CEMS data, instrument records, laboratory reports, LDAR surveys, meter exports and calibration or maintenance history. For estimates, retain the factor source, version, units, applicability, calculation and approval. US EPA AP-42, IPCC guidance and GHG Protocol tools serve different purposes; use the source appropriate to the inventory.

Quality and governance records

Create a data owner and reviewer list. Retain QA/QC plans, calibration or check records, sample custody, laboratory scope where required, calculation versions, assumptions, gap logs and approvals. The inventory should distinguish measured, calculated, estimated and excluded values.

Common gaps to find early

Watch for these gaps:

• untagged sources
• missing meter months
• fuel invoices that combine sites
• inconsistent standard conditions
• unrecorded refrigerant recovery
• flare estimates without composition
• outdated factors
• test results unrelated to annual operation

Rank gaps by decision impact and assign closure.

The full facility emissions inventory measurement plan turns this information into sources, methods, schedule and responsibilities. Formal corporate accounting remains with the inventory practitioner.

Organise the first data room

Create folders or controlled records by boundary, source, activity data, measurements, factors, calculations, QA/QC and approvals. Use consistent file names with source ID, period and version. Keep raw exports and signed reports separate from working copies. Assign an owner for every folder and record access restrictions.

Prepare a data index that says what exists, what period it covers and whether it is approved. Do not wait until every gap is closed; a visible “missing” status is better than a blank folder. Select a few high-consequence sources and trace their evidence end to end. This sample often reveals whether units, operating periods and identities are consistent across systems.

Turn the facility emissions inventory data list into a plan

Rank sources by applicable requirement, expected contribution, variability and data quality. Confirm which need direct testing, which can use continuous data, which use approved factors and which require engineering review. Add site access, shutdown, laboratory and safety needs to the schedule. Assign reviewers and state the final use of each output. The resulting plan gives the facility a procurement scope and a longer-term improvement register rather than a one-time spreadsheet request.

Before issuing the inventory

Run a completeness check against the approved boundary and a vertical trace on material sources. Confirm that source IDs, reporting periods and units agree across records. Ask data owners to approve their inputs and the inventory practitioner to approve methods and estimates. Freeze the issued calculation version and retain the gap register. A later correction should create a documented revision, not overwrite the evidence that supported the original result.

For a recurring inventory, schedule the next collection before year end and add source changes to normal management-of-change processes. The best long-term data is created during operations, not reconstructed after the reporting deadline.
