FOUNDING MEMBERSHIP IS OPEN

The rules for this market are being written now.

We are building the standards, the registry and the exchange for clean hydrogen and ammonia. The companies that join now shape all three.

{{ frameIx }} / 05 · THE CORRIDOR, WORKING
01 · GENERATION
Gulf sun, at scale
The cheapest new electricity on earth, built for export rather than the local grid.
02 · CONVERSION
Into molecules
Hydrogen and ammonia, because electrons cannot be shipped and molecules can.
03 · EXPORT
Loaded and gone
Terminals financed now, ahead of any market that can price what leaves them.
04 · ARRIVAL
The proof stays behind
The cargo travels. The evidence of what made it clean does not travel with it.
01 THE IDEA THE FUEL, AND THE PROOF IT IS CLEAN
A clean cargo is two things. Today they are sold as one.
THE FUEL
The molecule itself
A buyer, a ship, a delivery date and a price. This part of the market already works.
THE CLEAN PART
The proof it is clean
What regulators tax, what buyers pay extra for, what banks demand. It has no market of its own.
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.
02 WHY NOW THE DEADLINES ARE ALREADY IN LAW
{{ daysUp }}
DAYS
COUNTED, NOT PRICED
until hydrogen must be matched to clean power hour by hour to count as renewable in Europe.
Most of this market cannot yet prove the year. CBAM is already charging importers for embedded emissions, and applies an expensive default when the real figure cannot be evidenced.
03 WHAT WE ARE BUILDING THREE STAGES, NONE OF THEM FINISHED
Three things, at three stages.
IN CONSULTATION
The standards
What counts as clean, how it is proved, and the contracts to trade it. Ninety-five documents, drafted and independently reviewed. Members are reading them and telling us what is wrong.
IN BUILD
The registry
Where the clean part of a cargo is issued, owned, transferred and retired, so one unit can only ever be claimed once, by one company, for one year.
IN DESIGN
The exchange
Where it is bought and sold, so a price exists that a producer can bank against and a buyer can budget for. Rules drafted; ownership being settled.
FOUNDING MEMBERSHIP THE RULES ARE BEING WRITTEN NOW

WHAT WE DO

We are building the market, not describing it.

Three pieces have to exist before the clean part of a cargo can be bought and sold like anything else: rules everyone agrees on, a record of who owns what, and somewhere to trade. We are building all three at once, because none of them works alone.
IN CONSULTATION
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 independently reviewed. Members are reading them and telling us what is wrong before anything is fixed.
IN BUILD
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.
IN DESIGN
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.

THREE CARGOES, THREE FATES, ONE RULEBOOK
SHIPPED
Moved as a molecule
Hydrogen and ammonia travel by sea. The attribute has to travel with the cargo, or it does not arrive at all.
BURNED
Consumed on delivery
e-SAF is gone the moment it is used. The evidence has to exist before the wing is filled, not after.
EMBEDDED
Built into a good
Steel and aluminium carry their emissions into the product, and across the border with it.

TRANSMISSION
TERMINAL
SHIPPING
PHYSICAL ASSETS ONLY. IF IT CAN BE BUILT, PERMITTED OR METERED, IT BELONGS HERE.
02 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.
03 THE TOOLS, FREE TEST THE WORK BEFORE YOU TRUST IT
You can test our work before you trust it.
THE STANDARDS

Read them before you join, not after.

Written in the open. Read by members first.
Nothing here is released yet, and while it is being written the drafts go to members. That is not a paywall on finished rules. It is early sight of unfinished ones, with the standing to change them before they harden.
What the library holds is listed below in full, so you can see the shape of the work before you ask for a seat. Every document states what it is and what you may rely on, which today is orientation and nothing more.
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.

Retirement and invalidation are terminal. A unit that has supported one claim can never support another; that is the entire point of the registry.

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.
REGULATION

Which of your obligations this helps with, and where it stops.

The regulator asks one question. The crosswalk answers it.
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.
01 WHAT A CROSSWALK IS FIVE COLUMNS. THE FIFTH IS THE ONE THAT MATTERS.
COLUMN 1
The obligation
Named with its instrument and article, as the regime writes it, not paraphrased into our own vocabulary.
COLUMN 2
The evidence in practice
What actually satisfies it: metering data, PPA documentation, asset identity, retirement records.
COLUMN 3
Our records and requirement IDs
The specific requirements that carry that evidence. Citable, testable, traceable to a clause.
COLUMN 4
The relationship
One of four verbs. Not a claim of compliance, a statement of how the two relate.
COLUMN 5
The honest gap
What is still missing. Written in the same row as the mapping, not in a footnote at the end.
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.
02 HOW A CLAIM TRAVELS FROM AN OBLIGATION TO THE CLAUSE THAT EVIDENCES IT
01
The obligation
A regulator names something you must prove.
02
The crosswalk row
Points at the requirement IDs that carry evidence for it.
03
The document
The requirement ID resolves to a clause in a controlled document.
04
The validator
The same requirement is enforced mechanically on a real artefact.
05
The evidence
A proof bundle, anchored, that a verifier can re-perform.
No permission is required at any step. Anyone can walk it without asking us, which is the only reason the map is worth publishing.
RED III · HOURLY MATCHING
On 1 January 2030 the hour becomes the unit of proof.
Monthly matching ends. Every megawatt hour claimed renewable must be matched to the hour it was made, and the systems that survive that day are being specified now.

WHAT WE CARRY
{{ d }}
WHAT WE DO NOT DO
{{ n }}
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.
FOUNDING MEMBERSHIP
A seat while the definitions are still open.
Every rule in this market is being written now. Members write them, and hold the standing to change a draft before it hardens.
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.
GENERATION IS SOLVED · DEFINITION IS NOT
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.
Regular
FULL DECISION RIGHTS
● Vote on standards and methodologies
● Up to three working-group seats
● Propose a new standard
● Stand for the Board
● Three roundtable delegates
● Drafts at consultation stage
ZETA MEMBER · REGULAR
Associate
PARTICIPATION, NO VOTE
○ No vote on standards
● Working groups as observer

ZETA MEMBER · ASSOCIATE
Contribution is agreed in conversation with the Secretariat when you join. Governments, regulators and academic institutions participate without charge.
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
Send someone who can sign
Working groups move at the speed of their mandate, not their attendance.
04 NEUTRALITY, IN WRITING
Not a policy. A constitutional constraint.

ZETA holds no trading book, operates no marketplace and no registry today, and takes no position in any product it defines. It publishes no price assessment. These are constraints in the constitution of the foundation, and they are the reason a regulator and a trader will sit at the same table.

Recognition attaches to methods and platforms, never to companies. A member firm’s mark never appears on a standard.

HOW A STANDARD PASSES
Draft  →  Consultation
Consultation  →  Member vote
Vote  →  Board ratification
Ratified  →  Published with named adopters
WHAT MONEY CANNOT BUY
A recognition decision
An endorsement of your firm
A definition written to your book
Exclusive access to a standard
A seat on the Board
If ZETA ever benefits from the outcome of a definition it writes, it has stopped being useful to the people who rely on it.
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
Regular or associate, agreed in conversation with the Secretariat rather than read off a rate card.
03

Working groups are seated on joining, and the next roundtable is already being convened.

ABOUT

The Zero Emissions Traders Alliance.

A Dutch foundation building the standards, the registry and the exchange for clean fuels, working from the corridor between the Middle East and its export markets. We are not a company selling software, and not a consultancy selling advice on our own rules. ZETA is an affiliate of Dii Desert Energy, and stands on that network’s fifteen years of convening in the corridor.
