Direct answer: A green-power/green-certificate procurement page is not a line saying "buy some green power". The page should state: green-power trading (trading parties/products/period/price/deviation/settlement/metering); green certificates (issuance/trading/transfer/cancellation/uniqueness/corresponding volume/environmental attributes); supplementary options such as distributed PV, self-owned generation and PPAs; metering and settlement (gate meter/sub-meter, metering point, meter reading, line loss, peak/valley/demand, settlement period, invoice); disclosure and claims (RE100/CDP/CBAM/customer questionnaires, time/geographic matching, double counting, audit evidence); contract terms (volume/price/deviation/certificate transfer/environmental attributes/breach/exit); and what the website may and may not publish. On the policy basis: NDRC/MOF/NEA Notice 2023 No. 1044 on full coverage of renewable energy green certificates clarifies full coverage, that a green certificate is the sole proof of the environmental attributes of renewable energy electricity, and that one certificate corresponds to 1,000 kWh; NDRC/NEA Notice 2024 No. 1123 (Green Power Trading Chapter) covers trading organisation, products, price and certificate transfer; the Civil Code addresses power/ sales contracts. This article is current to 2026-11-09 and is a summary of public rules and page method, not power-trading or carbon-asset advice; trading rules, contracts, grid/exchange settlement and authority practice control.
This article is for energy, procurement, finance, ESG, legal and website teams at equipment, electronics, automotive-parts, medical-device, hardware, chemical, packaging and export manufacturers in Changzhou and nearby. It covers how to write and accept a green-power/green-certificate procurement page. The usual gap is "certificate uniqueness, green power vs certificate, metering point, deviation settlement, environmental attributes, double counting, disclosure basis", ending with a page that only says "we use green power", while customer audits/CBAM/ESG disclosure cannot be evidenced.
First separate the products: green-power trading, green certificates, distributed PV, self-owned generation and PPAs are not the same. Then reconcile: volume, metering point, certificate transfer, environmental attributes and settlement period must match. Finally prevent double counting: certificate uniqueness, no double claim for green power plus certificates, time/geographic matching and complete evidence. "We use green power" is not enough.
How does this page relate to energy management, carbon footprint/CBAM, ESG, budget and contract pages?
The green-power/certificate page answers "what to buy, how to trade, how certificates are transferred, how to meter/settle and how to disclose"; the energy-management/unit-consumption page answers "energy use, unit consumption and savings"; the product carbon footprint/CBAM page answers "boundary, factors and verification"; the ESG/sustainability page answers "targets, progress and disclosure"; the procurement budget page answers "limit, encumbrance and execution"; the contract page answers "clauses, signing and breach". Green power/certificates are "energy procurement + environmental attributes + disclosure evidence" and cannot be replaced by an energy-management or ESG page.
Common breaks: treating a certificate as green power; certificate and volume not matching; metering point unclear; deviation/settlement not stated; environmental-attribute ownership unclear; double claiming green power plus certificates; time/geographic mismatch; customer questionnaire/RE100/CBAM bases differ; contract lacks certificate transfer/breach. The page separates "product—trading—certificate—metering—settlement—disclosure—contract—public boundary" so energy/procurement/finance/ESG/legal share one vocabulary.

How should green power, green certificates and supplementary options be distinguished?
At least: (1) green-power trading (power trading with green power and corresponding certificates as the subject); (2) green-certificate trading (buying certificates separately; one certificate corresponds to 1,000 kWh of renewable energy electricity, and a certificate is the sole proof of environmental attributes); (3) distributed PV/self-built renewables (self-consumption, surplus to grid); (4) self-owned generation/direct purchase (check whether certificates/environmental attributes are included); (5) PPAs/long-term power purchase agreements (a commercial contract form, not automatically a certificate); (6) energy-performance contracting/energy-saving services (savings are not green power). Each has different environmental attributes, metering, settlement and disclosure evidence; the page must state "power, certificate or environmental attribute", not just "green power".
Acceptance checks: product type; volume; certificate; environmental attributes; metering; settlement; disclosure evidence; contract. Common gaps: certificate as green power; PPA as certificate; self-owned generation assumed green; savings as green power; unclear attributes; unclear metering point.
| Option | Key points | Evidence | Common gap |
|---|---|---|---|
| Green-power trading | Green power + corresponding certificate, period/price/deviation | Trade/settlement | Power only |
| Green certificate | 1 certificate = 1,000 kWh, uniqueness, transfer/cancellation | Certificate | Treated as power |
| Distributed PV | Self-consumption/surplus, metering, attributes | Generation/settlement | Assumed green |
| Self-owned/direct purchase | Whether certificates/attributes included | Contract/settlement | Assumed green |
| PPA | Volume/price/certificate/attributes | Contract | Treated as certificate |
| Energy-performance contracting | Savings service, not green power | Contract/savings | Mixed with green power |
Product classification is editorial; trading rules, contracts and authority practice control.
How should green-power trading and settlement be accepted?
State: trading parties (generator/retailer/user/grid/exchange); product/period (annual/monthly/intra-month/multi-year); trading method (bilateral/centralised/listing per rules); volume/curve/price; deviation handling (positive/negative, assessment/settlement); metering point/gate meter; settlement period/invoice; certificate transfer; environmental-attribute ownership; contract/trade evidence. Settlement must reconcile "traded volume—metered volume—settled volume—certificate quantity—environmental attributes"; deviations need rules; cross-province/cross-region trading follows the rules and transmission/distribution tariffs. Do not just say "we bought green power"; produce trade/settlement/certificate evidence.
Acceptance checks: parties; product/period; method; volume/curve; price; deviation; metering; settlement; invoice; certificate; attributes; evidence. Common gaps: unclear parties; unclear period; no deviation; unclear metering; settlement/certificate not linked; unclear cross-province rules.
| Element | What to write | Evidence | Common gap |
|---|---|---|---|
| Parties | Generator/retailer/user/grid/exchange | Trade record | Unclear |
| Product/period | Annual/monthly/intra-month/multi-year | Announcement | Unclear |
| Method | Bilateral/centralised/listing per rules | Trade record | Not stated |
| Volume/curve | Volume, time curve, price | Contract/trade | Total only |
| Deviation | Positive/negative, assessment/settlement | Rule | Not stated |
| Metering | Metering point/gate meter/sub-meter | Meter record | Unclear |
| Settlement/invoice | Period, tariff, transmission/distribution, invoice | Settlement | Not linked |
| Certificate/attributes | Transfer, quantity, ownership | Certificate/contract | Not linked |
Green-power trading/settlement is editorial; trading rules, contracts and grid/exchange settlement control.
How should green certificates be checked and double counting prevented?
Check: issuing body/platform; certificate ID; corresponding volume (1 certificate = 1,000 kWh); generation project/time/geography; trading/transfer record; cancellation/holding status; environmental-attribute ownership; whether already used for another claim/customer delivery; whether duplicated with green-power trading. A certificate is the sole proof of environmental attributes, so the same certificate cannot be claimed repeatedly or sold to multiple customers; where green-power trading already includes the corresponding certificate, do not buy certificates separately and double count. Disclosure must trace "certificate—volume—time—project—holder—cancellation/claim"; cross-year/geographic/market matching follows disclosure rules. Do not rely on a screenshot.
Acceptance checks: platform; ID; volume; project/time/geography; trade/transfer; cancellation/holding; attributes; double-count check; disclosure chain. Common gaps: screenshot as evidence; volume mismatch; repeated claim; green power + certificate double count; cross-year/geography mismatch; unclear cancellation.
| Check | What to check | Evidence | Common gap |
|---|---|---|---|
| Platform/ID | Issuing platform, certificate ID | Certificate | Screenshot |
| Volume | 1 certificate = 1,000 kWh, quantity match | Certificate/settlement | Mismatch |
| Project/time | Generation project, time, geography | Certificate | Cross-year/geography |
| Trade/transfer | Holder, transfer record | Platform record | No record |
| Cancellation/holding | Cancelled/held status | Platform | Unclear |
| Attributes | Ownership, claim right | Contract/rule | Unclear |
| Double count | Green power + certificate/multiple customers | Ledger | Double claim |
Certificate checks are editorial; issuance/trading rules and disclosure requirements control.
How should metering, settlement and disclosure reconcile?
Metering: gate meter/sub-meter, metering point, multiplier, reading cycle, line loss, peak/valley/demand, data collection; settlement: traded/metered/settled volume, tariff/transmission/distribution/government funds, deviation, invoice; disclosure: RE100/CDP/CBAM/customer questionnaire basis (time/geography/market/volume/certificate/attributes), double counting, evidence chain, third-party verification. The three must reconcile: same period, same metering point, same volume, same certificate, same environmental attribute; split across periods/sites/customers. Do not use "total electricity" for "green-power volume", or "certificate quantity" for "actual electricity use".
Acceptance checks: metering point; reading; line loss; settlement; invoice; disclosure basis; time/geography; double counting; evidence; verification. Common gaps: unclear metering; total as green; certificate as consumption; no period split; double counting; no third-party verification.
| Step | What to write | Evidence | Common gap |
|---|---|---|---|
| Metering | Gate/sub-meter, point, multiplier, reading | Meter record | Unclear point |
| Line loss/peak | Line loss, peak/valley/demand | Settlement | Not stated |
| Settlement | Traded/metered/settled volume, tariff/funds | Settlement | Not linked |
| Invoice | Electricity/certificate/service fees | Invoice | Mixed |
| Disclosure basis | Time/geography/market/volume/certificate | Disclosure table | Inconsistent |
| Double counting | Green power + certificate/multiple customers | Ledger | Double |
| Verification | Third party/customer audit | Report | None |
Metering/settlement/disclosure is editorial; trading rules, settlement statements and disclosure requirements control.
Which green-power/certificate clauses should the contract contain?
At least: trading/contract parties; volume/curve/price; trading period/delivery; deviation/assessment/settlement; metering point/reading; certificate quantity/transfer/cancellation; environmental-attribute ownership; green power–certificate correspondence/no double counting; disclosure cooperation/evidence; breach/damages; exit/termination; force majeure/policy change; dispute resolution. The contract should answer "how much power, how many certificates, how certificates are transferred, who owns the attributes, how deviation is calculated, who supports disclosure, what happens on breach". Do not write "green power" as "green certificate", or assume environmental attributes belong to the buyer without saying so.
Acceptance checks: parties; volume/curve; price; period; deviation; metering; certificate; attributes; no double counting; disclosure; breach; exit; dispute. Common gaps: green power/certificate mixed; attributes not stated; deviation not stated; transfer not stated; disclosure not supported; weak breach.
| Clause | What to write | Evidence | Common gap |
|---|---|---|---|
| Parties | Generator/retailer/user/agent | Contract | Unclear |
| Volume/curve | Volume, time curve, price | Contract | Total only |
| Period/delivery | Annual/monthly/intra-month/multi-year | Contract | Unclear |
| Deviation | Positive/negative, assessment/settlement | Contract | Not stated |
| Metering | Point/reading/line loss | Contract | Unclear |
| Certificate | Quantity/transfer/cancellation/correspondence | Contract | Not stated |
| Attributes | Ownership/claim right | Contract | Assumed buyer |
| Disclosure/breach | Cooperation/evidence/damages/exit | Contract | Weak |
The clause list is editorial and not a contract template or legal advice; legal/energy/finance review before signing.
How should the website page be written, and what must not be published?
Suggested sections: (1) green power/certificate/supplementary types; (2) trading/settlement/metering principles; (3) certificate uniqueness/no double claim; (4) disclosure basis/evidence; (5) key contract clauses; (6) contact/update date. The public page explains "types, principles, process, boundaries" and does not publish specific trade prices/volumes, contract terms, suppliers/customers, certificate IDs/project details, settlement statements, disclosure workpapers or pending disputes; specifics are handled in energy/finance/legal controlled systems. Do not claim "100% green power/zero carbon/RE100 achieved" if you cannot prove it or are not authorised; disclosure must be true, verifiable and traceable.
The English page should use consistent terms (green-power trading, green certificate, renewable energy certificate, environmental attribute, PPA, metering point, settlement, additionality, double counting, RE100, CDP, CBAM) and state the cut-off date. It can link to energy-management, carbon-footprint/CBAM, ESG, budget and contract pages, but must not become a "we use green power" line.
| Section | What to write | Evidence | Avoid |
|---|---|---|---|
| Types | Green power/certificate/distributed/PPA/EMC | Contract/trade | Mix together |
| Trading/settlement | Period/volume/price/deviation/metering | Trade/settlement | Total only |
| Certificate | ID/volume/transfer/cancellation/uniqueness | Certificate | Screenshot |
| Disclosure | Time/geography/double counting/evidence | Disclosure table | Double claim |
| Contract | Attributes/transfer/breach/exit | Contract | Not stated |
| Public boundary | No prices/volumes/contracts/certificate details | Permissions | Publish all |
The page structure is editorial; public statements must be true and verifiable, and trading rules, contracts and disclosure requirements control.
Go-live acceptance checklist
Ten checks: product type/boundary; trading parties/period/price; deviation/settlement; metering point/reading; certificate ID/volume/transfer/cancellation; environmental attributes/no double counting; disclosure basis/evidence; contract clauses; system/ledger reconciliation; public boundary. Each needs evidence and a review date. The pass standard is not "the page says green power is used", but that energy/procurement/finance/ESG/legal can judge what is bought, how certificates are transferred, how volume is metered, how deviation is settled and how disclosure is evidenced.
Before go-live, run a tabletop exercise with a real (redacted) project: trading → metering → settlement → certificate transfer → environmental attributes → disclosure → customer audit. Then simulate "certificate double claim", "green power + certificate double count", "cross-year/geography" and "deviation over assessment" to see whether the page and process work.
| Check | Pass standard | Evidence | If failed |
|---|---|---|---|
| Product/boundary | Green power/certificate/distributed/PPA/EMC distinct | Contract/trade | Add classification |
| Trading | Parties/period/volume/price | Trade record | Add record |
| Deviation/settlement | Positive/negative, assessment, settlement | Settlement | Add rule |
| Metering | Point/reading/line loss | Meter record | Add metering |
| Certificate | ID/volume/transfer/cancellation | Certificate | Add certificate |
| Attributes/no double count | Ownership, green power + certificate no double count | Ledger | Remove duplication |
| Disclosure | Time/geography/evidence/verification | Disclosure table | Add evidence |
| Contract | Attributes/transfer/breach/exit | Contract | Amend |
| System/ledger | Trade/settlement/certificate/disclosure reconcile | Reconciliation | Reconcile |
| Public boundary | No prices/volumes/contracts/certificate details | Page/permissions | Take down |

Who should read it, who should not, and what decisions does it support?
For energy, procurement, finance, ESG, legal and website teams at equipment, electronics, automotive-parts, medical-device, hardware, chemical, packaging and export manufacturers in Changzhou and nearby; also for companies handling "certificate vs green power, unclear metering point, no deviation settlement, unclear environmental attributes, green power + certificate double claim, insufficient customer/CBAM evidence". Not for teams that do not involve electricity/green power, or that want one page to replace power-trading/carbon-asset advice.
Read it if: building a green-power/certificate page; only "we use green power"; certificate as power; PPA as certificate; attributes not stated; metering unclear; deviation not stated; green power + certificate double count; no disclosure evidence. Not suitable if: treating "certificate" as "green power"; treating "total electricity" as "green power"; treating "PPA" as "certificate"; treating "energy savings" as "green power". Supports: product/trading, deviation/settlement, metering, certificate/attributes, disclosure/evidence, contract and public-boundary self-checks.
FAQ
What is the relationship between green power and green certificates?
Green-power trading is power trading with green power and corresponding green certificates as the subject; a green certificate is the sole proof of the environmental attributes of renewable energy electricity, and one certificate corresponds to 1,000 kWh. Green-power trading usually includes the corresponding certificate/environmental attributes; buying certificates separately buys the environmental attribute. The two cannot be claimed twice; the page should state whether power, certificate or attribute is bought and how they correspond.
Can a green certificate be reused for multiple customers/claims?
No. A certificate is the sole proof of environmental attributes; the same certificate cannot be sold to multiple customers or used in multiple claims. If green-power trading already includes the corresponding certificate, do not buy certificates separately and double count. Keep a certificate ledger/cancellation/transfer record and trace "certificate—volume—time—project—holder—claim" in disclosure; issuance/trading rules and disclosure requirements control.
Does a PPA automatically include green certificates?
Not necessarily. A PPA is a commercial power-purchase contract; whether it includes certificates/environmental attributes depends on the contract and trading arrangement. Some PPAs sell only power without environmental attributes; some include certificate transfer. The page should state volume, price, certificate quantity/transfer, attribute ownership and deviation/settlement; do not treat "signed a PPA" as "has certificates".
Why is the metering point important?
Green-power/certificate disclosure must correspond to actual electricity; the metering point/gate meter/sub-meter determines which volume, site or customer the electricity belongs to. If the metering point is unclear, settled volume and disclosed volume will not reconcile. State the metering point, multiplier, reading cycle, line loss, peak/valley/demand, data collection and settlement period; split across sites/customers and do not use total electricity for green power.
How should deviation/settlement be handled?
Green-power trading has positive/negative deviation; the contract/rules should state assessment/settlement. Deviation affects the correspondence between volume and certificates; disclosure should adjust to actual settled volume/certificates. The page should state deviation definition, assessment standard, settlement period, invoice and certificate transfer; do not treat "traded volume" as "actual consumption" or "certificate quantity".
How should RE100/CBAM/customer questionnaires be disclosed?
First align the basis: time (annual/monthly), geography (project/market), volume (traded/metered/settled), certificate (quantity/transfer/cancellation), environmental attributes (ownership/uniqueness), double counting; then prepare evidence (trade/settlement/certificate/contract/verification); finally disclose under RE100/CDP/CBAM/customer rules. Do not use one basis for all customers, and do not claim "100% green power/zero carbon" without evidence.
Should the website publish green-power ratio, prices and contracts?
Usually not specific trade prices/volumes, contract terms, suppliers/customers, certificate IDs/project details, settlement statements, disclosure workpapers or pending disputes. The public page can explain green power/certificate types, trading/settlement/metering principles, certificate uniqueness/no double claim, disclosure basis/evidence, key contract clauses and a contact window; specifics are handled in energy/finance/legal controlled systems. Do not claim "100% green power/zero carbon/RE100 achieved" if you cannot prove it or are not authorised.
One-sentence takeaway
The green-power/green-certificate procurement page on a Changzhou manufacturer's website is not about "using green power"; it is about turning product types/boundaries, trading parties/period/price, deviation/settlement, metering point/reading, certificate ID/volume/transfer/cancellation, environmental attributes/no double counting, disclosure basis/evidence, contract clauses and public boundaries into a checkable list, so energy/procurement/finance/ESG/legal can judge what is bought, how certificates are transferred, how volume is metered, how deviation is settled and how disclosure is evidenced.
Research method and limitations
This article is a summary of public rules and page method, not power-trading or carbon-asset advice. It uses no unpublished trade prices/volumes, contract terms, suppliers/customers, certificate IDs/project details, settlement statements, disclosure workpapers or pending disputes; the tables and acceptance items are editorial and not trading/legal conclusions. NDRC/MOF/NEA Notice 2023 No. 1044; NDRC/NEA Notice 2024 No. 1123 (Green Power Trading Chapter); the Civil Code; trading rules, contracts, grid/exchange settlement and authority practice control. This article does not decide whether any specific trade/certificate/disclosure is compliant, and does not promise a green-power ratio, zero carbon or RE100; companies should check item by item against the project, contract and disclosure requirements.
