Which Functions Does a Green-Factory Energy-and-Carbon Platform Need? Twelve Official Functions Explained
The twelve functions and related scoring definitions here come from the 2025 green-factory assessment annex. They are a framework for that year, not a permanent mandatory checklist. Whether a platform has a working capability depends on real data, calculation rules, users, operation records and traceable evidence. Recheck current standards and annual requirements.
Understand What the Assessment Table Counts
In the 2025 annex, this is a positive quantitative indicator worth 6 points. The annex lists twelve assessable business functions and awards points based on implementation, operation and the number that meet the criteria. It gives a leading value of eight functions and a baseline of zero. These figures apply in that year’s annex; they should not be generalized to future years or all companies, nor can a product brochure prove that a function qualifies.
A stronger check asks whether each function has a real source, calculation logic, users, operational result and traceable record. A menu label without data or actual usage does not establish management capability.
The Twelve Business Functions, One by One
| No. | Official function area | Problem the platform should solve | Typical data foundation |
|---|---|---|---|
| 1 | Energy-use queries | Query use by energy type, organization, area, equipment and time | Metered electricity, water, gas, steam and heat |
| 2 | Energy volume and intensity calculation | Calculate totals, standard-coal equivalents and energy per product or output value | Energy readings, product output, industrial output value and conversion factors |
| 3 | Consumption analysis and energy-strategy recommendations | Find trends, exceptions and high-use periods and propose improvements | Historical use, production plans, device states and shifts |
| 4 | Energy-efficiency benchmarking | Compare against sector, process, equipment or company targets | Baseline and leading values, energy limits and historical best values |
| 5 | Energy-flow analysis | Show flows from purchase through conversion and distribution to final use | Meter hierarchy, conversion equipment, networks and organization structure |
| 6 | Energy balance and optimization | Analyze supply, demand, losses and equipment combinations to improve operation | Energy-balance sheet, equipment efficiency, loads and production constraints |
| 7 | Energy and emissions budget management | Allocate annual or monthly budgets and track variance | Business plans, production budgets, energy prices and emissions targets |
| 8 | Carbon emissions | Aggregate or account for emissions by organization, scope, energy and period | Activity data, emission factors, organization boundary and accounting rules |
| 9 | Carbon-footprint accounting | Build lifecycle inputs and results for principal products | Materials, production, transport, energy and product-unit data |
| 10 | Supply-chain carbon management | Collect and manage supplier, purchased-material and upstream/downstream carbon data | Supplier, procurement, material, transport and footprint data |
| 11 | Carbon verification support | Organize boundaries, data, factors, vouchers and versions for verification | Source registers, bills, meter records, calculations and attachments |
| 12 | Carbon-asset management | Manage allowances, compliance, trading, reduction projects or related asset records | Allowance, transaction, compliance, project and finance data |
Let Data Maturity Determine the Build Sequence
Do not buy a “complete” system simply because it lists twelve menus. A more practical sequence is to establish base data and calculations first, then add optimization and carbon-management capabilities.
- Stage 1: Data foundation. Set up metering points, organizational boundaries, energy queries and volume/intensity calculations. Align definitions for product output and value.
- Stage 2: Analysis and optimization. Add efficiency benchmarks, energy-flow and exception analysis, budgets and operating optimization.
- Stage 3: Carbon management. Build models for emissions, product footprints, supply-chain data, verification evidence and carbon assets.
What Can an Existing Energy Management System Reuse?
Companies with an EMS, energy management center or equipment-monitoring system can often reuse meter collection, subcategory queries, trends, alerts and some efficiency analysis. Examine product-output interfaces, organization and meter boundaries, emission-factor versions, supply-chain data, footprint models and evidence retention more closely.
If most data still comes from manual spreadsheets, begin with a lightweight register and calculation rules; there is no need to connect every system merely for visual effect. Platform scope should correspond to the fourteen assessment indicators, actual management goals and ongoing reporting requirements.
How to Verify That a Function Is More Than a Page
- Traceable data: A displayed number can be traced to an API, meter, bill or manual register.
- Reproducible rules: Formulas, unit conversions, emission factors and versions are recorded.
- Explainable results: Exceptions, budget variances and benchmark gaps have causes and responsible owners.
- Functions in use: User, time, report, action or task records show ongoing operation.
- Exportable evidence: Reports, detail records and attachments can be organized by year, organization and indicator.
| Evidence layer | Minimum check | Suggested retention | Responsibility boundary |
|---|---|---|---|
| Data source | Origin and time for meters, bills, production, procurement, suppliers or manual registers | API inventory, raw records, quality state and known gaps | Source owner confirms authenticity and applicable scope |
| Calculation rule | Organization boundary, period, unit conversion, emission factors and versions | Formulas, parameter versions, recalculation sheet and change log | Business, energy or carbon owner approves definitions |
| Function operation | Who used a function, when, with what input, output and follow-up action | Account roles, operation logs, task or report samples | A menu alone does not demonstrate implementation or compliance |
| Evidence and review | Can function descriptions, results, attachments, versions, exceptions and owners be linked? | Evidence index, exported files, review records and closed corrective actions | System materials are only one form of evidence, not an assessment or certification conclusion |
How to Arrange Visualization Pages
A management home page can show energy and emissions, readiness of the fourteen indicators, budget variance and priority exceptions. Working users need meter queries, formula detail, benchmarking basis, evidence archive and permission audits. More pages are not inherently better; what matters is that dashboard conclusions can be traced to backend data.

Function names and assessment methods should follow current annual rules, sector standards and management-platform guidance. Building a system does not equal passing an assessment.
Frequently Asked Questions
Must a green factory build all twelve energy-and-carbon functions at once?
No such universal conclusion follows from the 2025 annex. Its twelve functions and scoring apply in that context, not as a requirement that every company or future year implement all twelve at once. Check current standards, annual rules and actual management needs.
Can an energy management system cover energy-and-carbon platform requirements?
Not always. A traditional system often handles meters, queries and consumption analysis, while emissions, product footprints, supply-chain management, verification and carbon assets may require additional data models.
Should the platform start with a dashboard or data integration?
First verify metering points, organization boundaries, production data, formulas and interface quality. Then define backend and visualization pages. A dashboard cannot substitute for the data foundation.
What evidence should be retained after functions go live?
Keep function descriptions, sources, formulas, API inventory, operational screenshots, user-action logs, version history and representative reports, with confirmation from the responsible business department.
