Overview

Practice positioning.

A carbon registry is the system of record for an entire jurisdiction or programme. It must serialise units uniquely, track lineage through transfers and retirements, prevent double-issuance and double-claiming, and remain auditable across decades. CAS has advised on the design and implementation of multiple sovereign registries. Our approach combines a hardened serialisation primitive, an immutable event log for lineage, an interoperability fabric (CAD Trust, ITMO bridge, custom federations) and a public transparency surface that satisfies civil society and buyers without exposing sensitive participant data.

Engagement model

How CAS delivers.

Phase 01

Identity & access

Account holders, role-based access, delegated authorities, KYC integration, sanctioned-party screening.

Phase 02

Serialisation primitive

Globally unique block IDs, vintage, methodology, country, project, with structured metadata for downstream filtering.

Phase 03

Lineage ledger

Issuance → transfer → split → retirement events captured immutably. Replayable for audit and dispute resolution.

Phase 04

Interoperability fabric

CAD Trust publication, Article 6.2 ITMO bridge, bilateral pull/push APIs, conformance test suite.
