STANDARDISED
One set of rules
Ninety-five documents, drafted in the open and put out for comment before anything is fixed.
DIGITISED
Proof that moves like data
Every unit carries the hour it was made and the evidence behind it, so a buyer can check rather than trust.
DIVERSIFIED
Molecules and electrons
Hydrogen, ammonia, methanol, e-fuels and power, on the same rules and the same record.
TRUSTED
Failures stay visible
When evidence does not hold up the unit is void on the record, with the reason attached. Nothing is quietly deleted.
01
THE IDEA
THE FUEL, AND THE PROOF IT IS CLEAN
A clean cargo is two things. Today they are sold as one.
SEPARATE THEM
The clean part becomes tradable on its own, priced, financed and settled independently of the plant that made it or the ship that carried it. That is the market ZETA exists to create.
{{ c_intro }}
The standards
Rules that say what counts as clean, how it is evidenced, and how it is bought and sold, written in the forms this industry already uses, so a trader or their counsel opens them and knows where everything is.
RIGHT NOW
Ninety-five documents, drafted and cross-referenced. Members are reading them and telling us what is wrong before anything is fixed.
The registry
A record of who owns the clean part of a cargo. Only a registry can guarantee that one unit is claimed once, because only a registry can see every unit at once.
RIGHT NOW
Being designed with the companies that will use it, so it fits how they actually work rather than how it would be convenient to assume they work.
The exchange
Somewhere to buy and sell it, so a price exists. Without one, the clean part stays a private negotiation between two parties who each keep their own books.
RIGHT NOW
Trading and auction rules are drafted. Structure, ownership and governance are being settled deliberately rather than arrived at by accident.
01
WHAT IT COVERS
FOUR CARRIERS, ONE RULEBOOK
Every carrier that can hold clean value.
The rules are written once and applied per carrier, so a hydrogen certificate and an ammonia certificate are the same instrument with different contents, and a benchmark can group them honestly.

THE ARTEFACT
THE RECORD THE MARKET TURNS ON
This is the thing that gets traded.
Not the cargo and not a PDF attached to it. A record with a life of its own: issued once, owned by one party at a time, retired against one claim, and checkable by anyone without asking us.

ONE UNIT, ONE CLAIM
This tonne can be retired against exactly one claim, by one company, for one reporting year. After that the record shows it as spent, for ever.
TRANSFER IS THE REGISTRY EVENT
Ownership changes when the registry records it, not when the paperwork is signed. One authoritative answer to who holds this, at any moment.
IF THE EVIDENCE FAILS
Even after retirement, a certificate can be invalidated and replaced, with the original claim still visible in the record. Nothing is quietly deleted.
SPECIMEN
An illustration of the record under design. No certificate has been issued and no registry currently holds ZETA recognition.

THE LIBRARY, HONESTLY
Ninety-five controlled documents. 1 432 identified requirements. Released for reliance: none yet.
The last number is the honest one. It moves when members vote, not before.
01
THE IDEA UNDERNEATH ALL OF IT
D00 · WHERE EVERY RULE STARTS
Four things that must never be mistaken for each other.
Almost every failure in environmental markets is one of these four collapsing into another. A certificate sold as though it were the attribute. An attribute claimed twice because nobody could see both claims. Keep them apart and most of the failures become structurally difficult.
01
The cargo
The hydrogen, the ammonia, the megawatt hour. The physical thing that moves.
02
The attribute
What makes it clean: when, where and by what method it was made. This is the thing that gets traded.
03
The certificate
The record that evidences the attribute and tracks its life. Evidence of the thing, never the thing.
04
The contract
The instrument that transfers, settles or remedies it. Not the certificate, even where it names one.
KEPT APART, ALWAYS
One unit supports one claim at a time. The registry event, not the paperwork beside it, is what moves ownership.

NINETY-FIVE CONTROLLED DOCUMENTS PLUS THE ORIENTATION AND READING AIDS · ARCHIVE TIER NOT SHOWN

STATUS
Nothing here is released. Every document is a draft, legal reliance is gated jurisdiction by jurisdiction, and the counsel opinions are unsigned working drafts. We would rather publish that plainly than let a reader assume otherwise.
{{ c_lead }}
The question is always the same: which of my obligations does this actually help me meet, and where does it stop? We answer it in a table: the obligation on the left, the requirements that carry evidence for it in the middle, and the honest gap on the right.

WHAT A CROSSWALK IS
FIVE COLUMNS. THE FIFTH IS THE ONE THAT MATTERS.
THE FOUR RELATIONSHIP VERBS
{{ v.k }}
{{ v.d }}
WHY EACH ONE SAYS WHAT WE DO NOT DO
Because a crosswalk is the document most likely to be over-read. A reader who wants ZETA to mean compliance will find a way to read it that way unless the page forecloses it. So each one states, in its own voice and before the sources, exactly what it does not do: confer status, file anything, perform the computation, or make a certificate eligible.
Each also carries a review date and an owner, because a crosswalk to a moving regime is a maintenance commitment, not a publication.

GOODS ALREADY IN SCOPE
CBAM, DEFINITIVE FROM 2026
Steel
Route matters more than tonnage. An electric arc furnace and a blast furnace are different numbers, and only one of them can be evidenced cheaply.
Aluminium
Almost entirely a power question. Where the electricity came from, hour by hour, is most of the answer.
Cement
Process emissions from the chemistry itself, which cleaner power cannot abate. The evidence trail is the only lever an importer has.
Fertiliser
Ammonia is the feedstock, so a clean fertiliser claim rests entirely on a clean hydrogen claim upstream of it.
RECOGNITION
ZETA holds no recognition under any of these regimes. For renewable hydrogen, standing comes only through schemes the Commission has recognised. As at December 2024 those are ISCC, REDcert and CertifHy, and we are not among them. Our work structures and evidences compliance data. It does not constitute compliance.
01
THE GAP
The constraint is not resource, technology or capital.
It is that no two counterparties describe the same cargo the same way, and no attribute verified in one jurisdiction is accepted in the next.
That gap closes over the next twenty-four months, and it closes in one of two ways.
OUTCOME A
The firms that trade these products write the definitions.
OUTCOME B
They arrive from elsewhere, and every term sheet is renegotiated against them.
02
WHAT MEMBERSHIP RETURNS
Four workstreams. Four things that land on your desk.
01
Comparable products
STANDARDS
One published definition per product, per basis. Your quote and your competitor’s finally describe the same thing, which is the precondition for a market, and for a hedge.
02
Financeable structures
MARKET ENABLEMENT
Risk-transfer and settlement frameworks, plus CBAM and compliance mappings: the material your credit committee and your lender ask for and rarely get.
03
The neutral room
CONVENING
Roundtables where a producer, a regulator and a lender can disagree in public without a commercial interest presiding. Every roundtable carries one decision item.
04
Recognition that travels
PLATFORMS
Registry and platform specifications, and the mutual-recognition frameworks that make an attribute you hold acceptable in the market you sell into.
WHAT MEMBERSHIP DOES NOT BUY
A newsletter. A logo on a website. A recognition decision. Membership buys a vote on the definitions your contracts will reference, and a seat in the working group where the delivery basis for your product is decided.
03
TWO TIERS
The difference is decision rights, not access to information.
Both tiers read the same library, in full, including drafts that are not public. What regular membership adds is the ability to shape them before they publish.

What we ask in return
01
Adopt the definition
In term sheets after your effective date. Specification, basis and measurement only. Commercial terms untouched and unseen.
02
One registry
Issued once, retired once. Double counting is the one failure ZETA cannot absorb on a member’s behalf.
03

Working groups move at the speed of their mandate, not their attendance.
05
TO JOIN
Three steps, and a date in the calendar.
01
Tell us what you trade
A short conversation with the Secretariat about your products, your obligations and which working groups would matter to you.
02
Agree the shape
Founding or associate, agreed in conversation with the Secretariat rather than read off a rate card.
03

CONTACT
PRIVACY, IN PLAIN ENGLISH
The forms on this site (event registration, the enquiry and the Signal signup) send what you type to the Secretariat. Registration confirmations and our mailings are sent through Brevo, an EU company based in Paris, which handles your address only to deliver mail on our behalf. Our mailings record whether they were opened and which links were clicked, so we can tell what is useful; that is the only measurement in them. We count page views with Plausible, which is hosted in the EU, sets no cookies and never sees who you are. No advertising pixels, and no cookies beyond the session that keeps a member signed in. We write to people who asked to hear from us or who work with ZETA, and every mailing carries a one-click unsubscribe, after which we send you no more of them.
To see, correct or delete anything we hold about you, write to the Secretariat at the address in the CONTACT tile above. © ZETA (Zero Emissions Traders Alliance) Global Stichting.

The corpus may be read, quoted and implemented with attribution to ZETA; recognition attaches to methods, not to companies, and nothing in it is for reliance until the document says so.
