Close monthly carbon data by showing which activity is covered, which figures are estimated and what still needs evidence. A late invoice should trigger a controlled estimate or an explicit gap, followed by a documented replacement when actual data arrives. It should not silently disappear from the reporting period.

This guide proposes an internal close process for UAE multi-site organisations and regional reporting teams. GHG Protocol's Corporate Standard sets an inventory foundation based on relevant, complete, consistent and transparent information. It does not prescribe the monthly close workflow described here or establish a universal UAE filing deadline. GHG Protocol Corporate Standard

Key takeaways

Track expected sources before collecting files. Assign activity to its actual period using a documented method. Label estimates and connect them to later evidence. Reconcile revised totals so that an estimate and its replacement cannot both remain in the inventory.

Build a coverage register

List the sites, accounts, equipment or other activity sources expected in the period. Give each a responsible data owner and a clear status: actual evidence received, estimated with an approved basis, confirmed no activity or unresolved. A missing file is not proof of zero consumption.

Check the register when sites open, close or change responsibility. Compare it with relevant operational and purchasing records so that a new account is not omitted because nobody added it to a mailing list. Separate activity completeness from the later choice of emission factor.

Set a cutoff and an estimation route

Agree when the internal report closes and who may approve an estimate. Choose the estimation method according to the source and available evidence, such as meter readings, operating records or an appropriate historical basis. Record the assumptions and limitations rather than using the previous month automatically.

GHG Protocol's tools hub stresses activity-data quality and quality control before calculation. Our proposed close register makes those issues visible to the reviewer before a total is presented. Where an important gap has no defensible estimate, report the limitation and hold the affected conclusion. GHG Protocol calculation tools and guidance

A hypothetical close across several activity sources

Assume an invented UAE group expects three activity records from each of two sites: electricity, generator fuel and refrigerant service movements. Five of the six expected records arrive before the internal cutoff. The sixth is a missing fuel record, while one received electricity record needs a supported period allocation. All quantities and circumstances are invented.

The close owner reports coverage as five records received out of six expected, with quality status shown separately. Receiving five files does not mean five figures are ready to calculate. Facilities resolves the electricity allocation; the fuel owner prepares a justified estimate or records an unresolved limitation. The reviewer approves the treatment before the total moves to management reporting.

When the missing record arrives, it replaces the identified estimate through the revision register. The next management report explains the change to the prior period separately from current activity. This combined coverage and revision check prevents an apparently complete folder or a smooth trend chart from concealing an unfinished close.

Replace estimates through a controlled bridge

Give every estimate an identifier linked to its source and period. When actual evidence arrives, record the old value, new value, difference, reason and approval. Preserve the original reported version so readers can understand subsequent changes.

Check for partial replacements. An invoice may cover only part of an estimated period or combine several accounts. Do not remove an entire estimate until coverage has been reconciled. Keep credits, cancelled bills and rebills linked to the original record instead of treating them as unrelated positive consumption.

Worked example: replace a fuel estimate without adding it twice

The following records and quantities are fictional. Assume the same generator, fuel unit and reporting period throughout; this demonstrates activity-data control, not an emissions calculation.

RecordLitres included in the original closeTreatment when actual evidence arrives
Other supported fuel records9,000Keep unchanged
Missing generator record, estimate E-011,000Remove this estimate from the current calculation
Actual record replacing E-01Not yet availableInclude 1,120 litres once
Reporting-period total10,000Revised total: 10,120

The bridge is 10,000 − 1,000 + 1,120 = 10,120 litres. Adding the actual record without reversing the estimate would give 11,120 litres and overstate activity by 1,000 litres. The revision is +120 litres, not +1,120.

A useful change record would say: “E-01 replaced in full by the actual generator record for the same period; activity total increased by 120 litres; prior reported version preserved.” Record the real evidence reference, reviewer and revision date when this method is used.

If the actual document covers only half the estimated period, this full replacement is unsuitable. Reconcile its coverage and retain or revise the unsupported remainder explicitly. Recalculate emissions separately using the appropriate factor and method; the activity bridge alone establishes neither factor suitability nor an externally reportable result.

Review the close before reporting a trend

Ask the reviewer to inspect completeness, large changes, unresolved estimates and replacement activity. A month-on-month fall may reflect missing sources rather than reduced emissions. Present data-quality changes separately from operational explanations where they materially affect interpretation.

Use electricity evidence for MENA operations for the supporting electricity evidence, while keeping this close process broad enough for other activity sources. Establish an appropriate process for correcting externally reported information; an internal monthly revision policy does not automatically satisfy a reporting scheme's requirements.

Questions teams ask

Can we close with estimated data

Where the selected method and reporting requirements permit it, a transparent defensible estimate can support an internal close. Disclose its basis and limitations and plan its review.

Does the invoice date determine the activity period

Not necessarily. Use the period in which the activity occurred, applying a documented allocation where evidence spans reporting periods.

Should a late invoice reopen every report

Assess materiality, purpose and applicable rules. Keep the change traceable even when the approved policy updates a later internal report rather than reissuing an earlier one.
