Services & fees

Twelve services. Three classes, never mixed.

Verification produces a public claim. Assurance produces an internal or buyer-facing report. Advisory produces neither — and we do not sell it, because doing so would disqualify the other two.

Class I — Verification (public claims)

Service	Deliverable	Standard	Fee (CNY)
Product carbon footprint	Quantified verification statement for one production batch: boundary, functional unit, factor inventory, allocation rules, uncertainty	ISO 14067 · ISO 14064-3	28,000 first year 12,000 surveillance / yr
Carbon label issuance	Label ID, hash, registry entry, public verification page	ISO 14067 + rule LR-01	40 / batch (≥200 batches)
Baseline determination & co-signing	Baseline study signed by both parties and archived — the denominator of every reduction claim	ISO 14064-2 method	6,000 / exercise
Evidence grade assessment	A / B / C grade (metered share, traceability completeness)	Rule DQ-02	4,000 / site / yr

Class II — Assurance (no public claim)

Service	Deliverable	Used by	Fee (CNY)
Ledger integrity	Hash-chain sampling and re-derivation, including tamper tests	Platform · buyer due diligence	8,000 / exercise
Decision record assurance	Sampled review of decision outputs (we do not grade the model)	Buyer · insurer	15,000 / exercise
MRV system audit	Instrument, sampling frequency and data-flow conformity report	Farm · platform	20,000 / site
Buyer second-party assessment	Supply-chain evidence assessment against a buyer checklist	Importer · roaster	quoted per checklist

Class III — Services (no conclusion)

Service	Content	For	Fee (CNY)
Dispute re-derivation	Independent re-computation of a contested batch; technical opinion admissible as an arbitration annex	Buyer & seller	3,000 / case
Methodology adoption	Adopt and re-calibrate the method for another crop or region	Labs · other platforms	from 80,000
Training & personnel certification	Verifier / internal auditor training, two days, examined	Individuals · companies	3,500 / person
Label use licence	Trademark licence and annual surveillance	Certified clients	included in annual fee

Correction to an earlier figure. The methodology file once stated a verification fee of ¥15,000 per site. That number was set before an accredited body existed and cannot support ISO 14065-level verification: a full batch engagement is 5–7 person-days. The 28,000 above is 6 person-days at ¥3,800 plus insurance and administration, and is auditable.

Process

Ten working days, four stages

Every stage has a defined output. If a stage cannot be closed, the engagement stops there and you are billed for time, not for a conclusion.

Stage	Content	Working days
1 · Engagement & scope	Application, boundary, functional unit, data availability	2
2 · Document review	Methodology conformity, factor provenance, allocation rules	3
3 · Verification	On-site or remote: instruments, sampling, ledger, re-derivation	2
4 · Technical review & issuance	Independent reviewer sign-off; statement and label issued	3
Total	Excludes client-side data preparation	10

Evidence product

Container-level EUDR evidence pack

The EU regulation asks the importer to file a due-diligence statement for every shipment. It does not supply the evidence underneath that statement. We do: plot, batch and container, each hashed to the one before, recomputable in a browser — and no compliance conclusion is claimed on our side.

What it contains

Plot coordinates and the batch ledger digest, the footprint label of the batch, the review record, and the field mapping an importer needs when filing.

Price

¥3,000–8,000 per container, or 0.2–0.5% of cargo value. Per container, because enforcement and clearance act on the shipment.

What the evidence layer sells

Two products that do not need a signature

The signature belongs to whoever holds accreditation. Everything underneath it is ours to sell, and it is what makes a partner's signature cheap to produce.

Standard · M1

The verified unit

One batch, one boundary, one ledger entry, one recomputable hash. Metred, bounded, attributed, committed, recomputable — fail one and it is not a unit. Buyer pays ¥40–80 per batch; the grower pays nothing.

Service · M4

Registry as a service

The same recomputable register, run under someone else's brand: accredited bodies, associations, large buyers, ERP vendors. ¥30,000–100,000 per year plus ¥10–40 per batch.

Examples

Three industry chains, one evidence layer

An aeroponic coffee company, an insurer and a beverage brand: the same evidence layer applied to three different chains, each with a three-minute film and a table of what has to be proved at every link.

One evidence layer, three industry chains

A coffee company, an insurer and a beverage brand have almost nothing in common operationally. They have exactly one thing in common: every claim they make about carbon has to survive a question from someone who did not produce it. These three worked examples show the same evidence layer applied to three different chains.

What these are. Worked examples, not client engagements. No company named here is a customer, and the figures used are the worked examples already published on this site. Each film is about three minutes and can be watched with the sound off — the captions are burned in.

Case 01 · Coffee

Coffee: from a plantlet to a fund

Seven links — growing, processing, roasting, trade, warehousing and bean savings, crowdfunding, REITs — and at every link the same question: can the number be recomputed by the party relying on it.

Section film · 7 links · coffee

Nine links in three minutes: what each one has to prove, and what the evidence layer delivers.

Link in the chain	What has to be proved there	What we supply
Growing	The footprint per plantlet and the hour it was consumed in	Verified unit: batch, boundary, functional unit, grade
Processing	That the allocation rule was fixed before the numbers	Declared rule, published with the result, locked in the ledger
Roasting	That the blend weights are public	Mass-weighted blend with published shares
Trade	That the container links to a plot and a batch	Plot → batch → container chain; one evidence pack per container
Warehousing and bean savings	That the attributes survive the warehouse	Receipt bound to the batch hash; every movement leaves a trace
Crowdfunding	That the claim behind a reward tier is checkable	One label per batch with a grade and a hash
REITs	That the underlying data can be audited	Traceable lineage for land, equipment, stock and contracts

Boundary. The crowdfunding claim is disclosure, not a carbon credit. The REIT row describes a data input, not a route to listing.

Case 02 · Insurance

Insurance: underwriting the consequence of being wrong

An insurer pricing a low-carbon asset first needs to know what it loses if the number is wrong. That makes evidence grade a rating factor and makes the claim history a claims file.

Section film · 6 links · insurance

Three minutes on underwriting logic: asset, rate, wording, claims, portfolio and disclosure.

Link in the chain	What has to be proved there	What we supply
Before cover	What exactly is insured, and where its data comes from	Schedule of the asset plus data lineage: meter, period, calibration
Rate	How much variance sits behind the number	A / B / C grade by metered share; the grade is arithmetic, not opinion
Policy wording	Which conditions can be decided automatically	Checkable triggers: meter silence, baseline drift, boundary change
Claims	What the data said at the moment of loss	Append-only record with timestamps; edits are visible
Portfolio and reinsurance	That assets are comparable and can be pooled	One method version, boundary and functional unit across the pool
Disclosure	That a regulator can trace the source	Public registry plus a verifier anyone can run

Boundary. CarbonVerify does not underwrite, price risk or issue actuarial opinions. It supplies the recomputable record under all of them.

Case 03 · Beverage

Beverage: a bottle assembled across four countries

Ingredients in one country, concentrate in a second, filling in a third, market in a fourth. Everyone calculates their own piece; the evidence layer is what lets the pieces be added up.

Section film · 6 links · beverage

Three minutes on one bottle: ingredients, processing, packaging, cold chain, distribution and the consumer claim.

Link in the chain	What has to be proved there	What we supply
Ingredients	Primary data rather than spend-based averages	Supplier batch footprint with an A / B / C grade
Processing	That the plant's allocation rule is fixed in advance	Rule declared before the result, then published
Packaging	Material mass and recycled content	Published factors per component
Cold chain	Consumption hour by hour, matched to weather	Hourly metering plus grid factors
Distribution	Distance, mode and load factor, with assumptions stated	Stated assumptions instead of one national average
Consumer claim	That the bottle's claim survives a scan	One label per batch; recomputation in a browser

Boundary. We do not print “zero carbon”. The label states the footprint of the batch, who measured it and how it was calculated.

What the three have in common

Question	Answer that works in all three
What is the smallest checkable thing?	One batch: one boundary, one functional unit, one ledger entry, one hash
How much can a buyer trust it?	An evidence grade computed from the metered share, not from the story
What if the number is wrong?	The record is append-only and recomputable, so the error is findable rather than arguable
What may be claimed without a signature?	Method, grade and register entry. Anything called certification needs a licensed partner
