Filing a CFO with TGO under CFO Version 04 — What to Prepare

Organizations registering a Corporate Carbon Footprint (CFO) with Thailand Greenhouse Gas Management Organization (TGO) must follow the TGO CFO Version 04 guideline, which prescribes both the calculation method and the reporting forms in detail.

The Fr-01 to Fr-05 form set

The submission centres on five forms: organization profile and boundary (Fr-01), emission sources by Scope (Fr-02), aggregated results (Fr-03), emission factors and their references (Fr-04), and the verifier summary (Fr-05). Every figure must reconcile across forms.

Where submissions get rejected

1. Emission factors quoted without a source and version
2. An unclear organizational boundary — which control approach was used
3. Figures that do not match source evidence such as electricity bills or fuel receipts
4. No record of who changed which number and when, so verifiers cannot trace back

How GCarbon helps

The system generates a monthly TGO Workbook and a submission-ready CFO Package directly from recorded activity data. Every number links back to its evidence and source EF, and the Readiness Engine checks before export whether the data is complete — and exactly where to fix it if not.

Preparing the team before the reporting cycle

A smooth CFO cycle starts with clear ownership: who owns electricity data, who covers fuel, who consolidates branches, and who reviews before submission. Organizations that assign a data owner per emission source at the start of the year never end up chasing documents across departments at the deadline. A monthly data close — like a financial close — surfaces problems in the month they occur, not at year-end.

From CFO to the next step

Organizations that register a CFO successfully usually build in two directions: Carbon Footprint of Product (CFP) to answer per-product customer requests, and science-based reduction targets (SBTi). Both draw on the same CFO base data — organizations with a sound data system never start from zero again.
