Compliance architecture for sovereign and voluntary markets.
Article 6.2 and 6.4 implementation, ETS design, CORSIA conformance and ICVCM-aligned compliance structures — engineered to withstand audit, host-country review and international scrutiny.
Indicative bands — final scope confirmed after a 20-minute discovery call.
Practice positioning.
Compliance is no longer a paperwork exercise. Article 6.2 transfers must reconcile against national inventories. Article 6.4 activities must satisfy a centralised supervisory body. ICVCM Core Carbon Principles gate access to high-integrity demand. CORSIA Phase II raises the floor for aviation eligibility. CAS translates these regimes into operational frameworks: authorisation procedures, corresponding-adjustment ledgers, methodology eligibility logic, host-country letters, and the underlying registry primitives. We work with both sides of the table — issuing jurisdictions and acquiring entities.
How CAS delivers.
Regime diagnostic
Establish which instruments apply (6.2, 6.4, CORSIA, domestic ETS) and the integrity requirements (ICVCM, ICROA, CCP labels) buyers expect.
Authorisation design
Draft LoA workflows, eligibility criteria, conditions of authorisation, and revocation triggers. Map to registry serial flags.
Adjustment accounting
Build corresponding-adjustment infrastructure — vintage, sectoral scope, NDC accounting, BTR reporting.
Reporting & assurance
Initial Report, Annual Information, BTR submissions; assurance partner selection; CMA review readiness.
