Marketplace Rules

Rules for listings, RFQs, buyer requests, supplier intake, public marketplace activity and brokered transactions.

Effective date: 30 May 2026. These are the current published terms for Carbon Trader® website and platform use.

Part 2 - Marketplace Rules

1. Purpose

These Marketplace Rules govern public and private listings, RFQs, buyer enquiries, seller mandates, credit lots, project records, evidence, public-facing disclaimers and marketplace conduct.

2. Listing standards

A listing must be accurate, current, evidence-backed and not misleading. The listing must identify, where relevant:

  • credit type;
  • standard or scheme;
  • registry;
  • project ID;
  • vintage;
  • quantity;
  • location;
  • host country;
  • methodology;
  • transfer or retirement pathway;
  • price or POA/RFQ status;
  • fees or pass-through costs;
  • claim suitability;
  • verification status;
  • settlement terms;
  • known restrictions or risks.

3. Public listings

A public listing must not disclose a seller’s identity unless authorised. Public listings are subject to seller acceptance, buyer verification and settlement terms. A public listing is not a guarantee of availability or immediate execution.

4. Private listings and mandates

A private mandate may be visible only to Carbon Trader administrators, selected brokers, selected buyers or invited participants. Carbon Trader may run private buyer outreach without public disclosure.

5. RFQ-only and POA listings

RFQ-only and POA listings invite expressions of interest or bids. They are not fixed-price offers. A seller may accept, reject, counter or request further verification before any transaction is formed.

6. Prohibited listings

Carbon Trader may prohibit listings involving:

  • credits with unclear ownership;
  • credits subject to undisclosed restrictions;
  • credits that appear double-counted or double-sold;
  • misleading environmental claims;
  • unsupported pre-issuance claims;
  • sanctioned parties or jurisdictions;
  • high-risk or disputed projects;
  • legacy or low-integrity credits unsuitable for modern claims;
  • credits Carbon Trader is not comfortable administering.

7. Marketplace integrity

Users must not manipulate pricing, create false buyer demand, submit fake bids, coordinate misleading listings, misuse confidential information or attempt to distort market signals.

8. Admin powers

Carbon Trader may edit, pause, hide, reject, approve, verify, flag, mark sold, reserve, remove or archive listings. Carbon Trader may also require further evidence before restoring a listing.
