Article 6 Transfer Mechanics: From Authorisation to Use

Article 6 transfer is the movement of authorised mitigation outcomes from a host country to a buying party, recorded in registries and matched by a corresponding adjustment so only one party counts the reduction. Within Carbon Credits, the idea is foundational: the way it is defined quietly determines how the whole market behaves.

The host country authorises units, issues or releases them in its registry, and records the transfer to the buyer's account or registry. At the same time the host adds the corresponding adjustment to its emissions balance, and the buyer reflects the unit in its own reporting. The sequence of authorisation, transfer and use is documented at each step. Reconciliation therefore depends on both sides recording the same volume and vintage.

The mechanics are what make an international carbon transaction legitimate under the Paris Agreement. They also determine what the buyer can claim, because a transferred unit is no longer available to the host country's own target. It fixes the point at which the seller loses the ability to claim the reduction, which is why payment terms are usually tied to registry confirmation rather than to signature. Because Article 6 transfer links technical detail to market behaviour, small errors in how it is handled can grow into large gaps in trust and value.

Practical experience with Article 6 transfer tends to reward patience and discipline: the organisations that document their assumptions, keep an audit trail, and revisit their methods are the ones that keep credibility when questions are asked.

Breakdowns occur when registries do not reconcile, when a unit is transferred but the adjustment is never applied, or when the buyer on-sells without passing the authorisation trail. Each gap creates a path to double counting. Delays are common when a registry requires manual processing, and in the interval a seller can lose track of which units have already been committed to another buyer.

CarbonFi records each transfer event on-chain with the registry reference and adjustment status, so the chain of custody from authorisation to retirement is visible in one place. CarbonFi also records which party bears the adjustment obligation at each stage, so responsibility does not silently fall between a developer, a broker and a final buyer. CarbonFi's model, which pairs an AI-driven digital MRV layer with an on-chain registry and marketplace, is built so that Article 6 transfer can be handled with transparency and traceability from end to end.
