CARBON ACCOUNTING & GHG EMISSIONS
Organisational Carbon Footprint (OCF)
Turn scattered factory records into a reviewable carbon baseline. Keep assumptions visible and decisions human-led.
AIGreen Plus proposes a practical OCF engagement for Malaysian manufacturers: set the organisational boundary, assemble activity records, document factors and assumptions, and prepare a reviewable calculation workbook. The work is scoped around your evidence and reporting period, not a pre-installed application or a guaranteed result.

An OCF engagement organises a manufacturer’s direct fuel and process data, purchased-energy data and selected value-chain activity into a corporate greenhouse-gas inventory. We help define sites and periods, structure Scope 1, 2 and relevant Scope 3 records, flag gaps, and prepare qualified-review materials. The client approves boundaries, factors and disclosures; this is consultancy and readiness support, not certified assurance, legal or tax advice.

PROPOSED DASHBOARD CONCEPT
FICTIONAL SAMPLE / four activity-record lines for FY2025 scopingOCF evidence and boundary review
Fictional evidence-status queue
Fictional sample values · Bars count visible review flags; they are not emissions, savings or compliance outcomes.
Unit: records
| Scope / category | Activity source | Activity data / unit | Evidence status | Factor status | Period |
|---|---|---|---|---|---|
| Scope 1 / stationary fuel | LPG boiler meter | 1,200 L | Complete | Checked | FY2025 |
| Scope 2 / purchased electricity | Utility invoices | 48,000 kWh | Complete | Pending review | FY2025 |
| Scope 3 Cat. 1 / purchased goods | Aluminium purchase ledger | 18 t | Partial | Supplier data pending | FY2025 |
| Scope 3 Cat. 4 / upstream transport | Freight records | 6,200 t-km | Partial | Checked | FY2025 |
AI-assisted draft / requires verification
Fictional draft: four FY2025 activity rows were reviewed; two show complete evidence and two need follow-up. The aluminium purchase row is the named exception. No emissions total or reduction conclusion is inferred from these rows.
02 / FIVE REVIEW STAGES
Five steps, with an accountable owner.
Evidence, assumptions and open questions move through a human review route. No certification or automatic conclusion is implied.

03 / RESPONSIBILITIES
Organise the work. Keep conclusions with people.
The proposed support can structure records and questions; responsible owners still assess evidence, applicability and decisions.
| Review point | Common starting position | Proposed consultancy support | Responsible reviewer |
|---|---|---|---|
| Define reporting boundary | Boundary choices sit in emails and spreadsheets. | Proposed structured boundary worksheet and decision log. | Authorised management approves entities, sites and exclusions. |
| Collect activity records | Teams chase invoices, meters and ledgers across functions. | Proposed workbook template with owners, periods, units and evidence links. | Owners provide accurate records and explain estimates. |
| Apply and document factors | Factor versions and units can be hard to trace. | Proposed factor register with source, version, date and unit checks. | Qualified reviewer selects or challenges factors and assumptions. |
| Prepare review pack | Reconciliation and gap notes are assembled repeatedly. | Proposed exception queue and draft summary based only on supplied rows. | Client signs off content; external assurance, if wanted, is separate. |
Create one evidence trail
Map utility, fuel, process, procurement and freight records into a controlled register without claiming completeness before review.
Make scope decisions explicit
Document included legal entities, sites, operational control or equity approach, period and exclusions for approval.
Make calculations traceable
Keep activity units, factor units, sources, versions, dates and estimates visible in the proposed workbook.
Prepare a usable baseline pack
Provide exceptions, assumptions and review questions so management can decide what to validate next.
04 / HONEST HYPOTHETICAL FIGURES
Show the working behind a planning example.
These figures are modest arithmetic for discussion, not customer evidence, forecasts, emissions claims, payroll promises or guaranteed outcomes.
HYPOTHETICAL WORKED EXAMPLE / NOT CUSTOMER RESULTS
90 → 60 combined labour minutes for the same task.
12 one monthly activity-record bundle for a defined site and source units per month × 30 minutes less per unit.
8 → 3 per 100 checked error-affected administrative entries, not incidents/accidents/disease/product defect outcomes (5.0 percentage points).
See assumptions and calculations
| Measure | Illustrative calculation | Meaning and limit |
|---|---|---|
| Labour effort | (90 − 60) ÷ 90 × 100 = 33.3% | Same workload and expected review quality; includes ongoing exception checks as scoped. |
| Time capacity | (90 − 60) × 12 ÷ 60 = 6.0 hours | Released time is not payroll savings or guaranteed job reduction. |
| Admin checks | (8 − 3) ÷ 100 = 5.0 percentage points; 62.5% relative | Separate hypothetical like-for-like administrative check of unit, period, evidence or factor fields; not a safety, compliance, certification or environmental-performance guarantee. |
Hypothetical same-workload comparison: manual gathering and checking takes 90 minutes per bundle; a proposed template and consultant/client review take 60 minutes, including exception effort. It measures administrative time only, not staffing, payroll, factory output or emissions change.
Scenario figures are illustrative arithmetic, not benchmarks, forecasts, actual customer results or guarantees. Measure a like-for-like pilot with the same definitions before making a claim.

Inputs, boundaries and ownership should be clear.
These lists are a starting point. Final scope, access, professional responsibility and outputs require written agreement.
What to prepare
- Approved entity, site and reporting-period list owned by finance or company secretariat
- Utility, fuel and refrigerant activity records with units, dates and source evidence owned by facilities or operations
- Production, process and purchased-material records needed for selected Scope 1 and Scope 3 categories owned by operations and procurement
- Freight, waste, business-travel or other selected value-chain records owned by logistics, HR or procurement
- Proposed factor register inputs: factor, kgCO2e-per-unit basis, source, version, date and approval status owned by the carbon reviewer
What to agree in writing
- This is scoped consultancy and a proposed workbook/template, not software already installed, an integration or an IoT feed; any mapping feasibility is separately agreed.
- Client owners approve boundaries, activity data, factors and disclosures; AIGreen Plus does not provide certified assurance or represent an accredited verifier.
- OCF is organisational accounting; product carbon footprints, LCA, offsets, neutrality claims and reduction-project quantification require separate scope and methods.
- Data access should be least-necessary, anonymised where practical and controlled by the client; retention, sharing and security terms require written agreement.
- Applicability to reporting, customer or regulatory requests must be confirmed for the organisation and period with qualified advisers; this page is not legal or tax advice.
Make activity, units and evidence easy to check.
Scope and category are proposed classification fields. Confirm organisational and operational boundaries first; the same activity must not be counted twice across sources. Scope 3 relevance and calculation methods require screening, not automatic selection.
Direct emissions within the agreed boundary
- Stationary combustion
- Mobile combustion
- Process emissions
- Fugitive emissions / refrigerants
Purchased or acquired energy
- Electricity
- Steam
- Heating
- Cooling
Other value-chain emissions

- Record the chosen method and estimation basis
- Keep upstream/downstream and lease boundaries consistent
Scope 3 category reference — fifteen categories to screen
- 01Purchased goods and services
- 02Capital goods

Category names follow GHG Protocol — Scope 3 Calculation Guidance (read 2026-10-22). The official public guidance lists fifteen Scope 3 categories and category-specific calculation methods. The list is a screening reference, not a finding that every category applies to a manufacturer.
| Field group | Example contents / selections | Review check |
|---|---|---|
| Record identity | Site/entity, reporting period, activity owner and source record ID | Keep the agreed boundary and period consistent. |
| Activity/source | Fuel invoice, electricity meter, shipment, supplier record or process record | Identify the evidence and whether the value is measured or estimated. |
| Quantity and selectable unit | Examples: litres, kg, kWh, km, tonne-km or units of product | Choose a unit appropriate to the method; do not interchange units without a documented conversion. |
| Emission factor and factor unit | Numeric factor field; example unit kgCO₂e/kWh or kgCO₂e/litre | No default or approved factor is supplied here. The factor denominator must match the activity unit. |
| Factor provenance | Source, version/year, publication date, geography, gas/GWP basis and method | Qualified reviewers approve applicability, conversion and any licensed factor data. |
| Evidence and reviewer | Document reference, estimation basis, data-quality flag, owner and approval status | Trace each calculation to approved records and retain unresolved exceptions. |
Optional fleet, maps and IoT feasibility
Fleet telematics, route/map services and meter or sensor data may be assessed later. Provider/API rights, devices, calibration, coverage, timestamps, quality, privacy, access security, compatibility and cost need discovery and written agreement. This website does not track vehicles, read sensors or collect live customer data.
This is an educational proposal panel, not a form, upload feature, factor database, live integration or calculated emissions result. Numerical dashboard values elsewhere are fictional; approved source data and qualified review are required for an actual engagement.
Confidence comes from traceable evidence.
Set definitions, boundaries, source ownership and review responsibility before interpreting a result. A qualified responsible person decides whether a finding is applicable.
07 / CLEAR ANSWERS
10 questions. Practical answers.
Clear answers
Frequently asked questions.
Ten practical answers about scope, sources, review and responsible use.
What does an OCF engagement cover for a Malaysian manufacturer?
It covers boundary scoping, activity-data organisation, factor and assumption documentation, gap review and a handover pack. The proposed structure separates Scope 1, Scope 2 and selected Scope 3 categories. It does not automatically include a product footprint, offset claim, assurance opinion or regulatory filing.
What data should we prepare first?
Start with the approved entity and site list, reporting period, electricity and fuel records, refrigerant or process data where relevant, and selected procurement, freight, waste or travel records. Each row should carry category, activity, unit, amount, factor, factor source/version/date and evidence.
Which method or standard will you use?
The proposed basis is the GHG Protocol Corporate Standard for a corporate-level inventory, with its Scope 2 Guidance for purchased electricity and other purchased energy. Relevant Scope 3 work can use the GHG Protocol Scope 3 Standard. Final choices depend on boundary, data and intended use.
Who signs off the footprint?
Client-authorised management approves organisational boundaries, exclusions, activity records, factors, estimates and any external disclosure. A qualified carbon reviewer can challenge methods and evidence. AIGreen Plus does not replace management accountability or provide an assurance opinion.
Is this certification or independent assurance readiness?
It can improve readiness by organising evidence and unresolved questions, but it is not certification or independent assurance. The GHG Protocol Corporate Standard focuses on accounting and reporting and does not prescribe how verification is conducted. Any external verifier is separately appointed.
Are the dashboard figures actual emissions or savings?
No. Dashboard rows and scenario values are fictional examples showing how a review pack may be structured. They are not customer measurements, emission totals, energy savings, headcount reductions or forecasts. Any approved footprint must use your reviewed records and documented factors.
Can confidential records be used?
Yes, subject to an agreed access route and least-necessary dataset. Use anonymised or aggregated records where possible, restrict permissions and identify the client data owner. Retention, confidentiality and cross-border handling should be set in writing with qualified Malaysian review where needed.
Can we start from existing ERP, utility or spreadsheet data?
Usually, if exports contain usable periods, units, amounts and evidence references. We first test completeness and consistency rather than promise an integration. Mapping or IoT feeds are optional feasibility work, not a current capability implied by this service.
How long will the work take?
Timing depends on the number of sites and entities, data quality, category coverage, factor questions and review availability. We confirm milestones after the scoping workshop. No fixed duration is promised before those dependencies are understood.
What is included in a quote and ongoing support?
A quote should state sites, periods, Scope 3 categories, workshops, data checks, deliverables, access, revisions and any follow-up review. Recurring refreshes, external assurance coordination, software, travel, training and regulatory advice are separate unless written into scope. Support levels are agreed, not assumed to be 24/7.

08 / SOURCE NOTES
Check the current public material.
These references support an initial discussion only. They do not make AIGreen Plus an accredited or certified verifier.
Public official material — not accreditation.
- GHG Protocol Corporate Accounting and Reporting Standard
The Corporate Standard provides requirements and guidance for corporate-level GHG inventories; it also distinguishes accounting/reporting from verification and notes Scope 2 Guidance for purchased electricity, steam, heat and cooling.
- GHG Protocol Corporate Value Chain (Scope 3) Standard
The Scope 3 Standard provides a global value-chain accounting methodology, covering 15 upstream and downstream activity categories and distinguishing corporate value-chain accounting from product-level accounting.
- GHG Protocol Scope 2 Guidance
The Scope 2 Guidance standardizes measurement of emissions from purchased or acquired electricity, steam, heat and cooling and describes requirements for energy contracts and instruments.
Official GHG Protocol pages support the accounting-method scope and distinctions described here. Applicability, boundary choice, factor selection and reporting treatment remain specific to the organisation and period and require qualified review; this consultancy page is not legal, tax or assurance advice.
Dashboards and numerical scenarios are fictional planning examples. The services are proposed consultancy scopes, not certification, accreditation, assurance, legal advice, regulatory approval or a promise of emissions, cost, staffing, safety, quality or market outcomes.
