OPEN PROTOCOL SPECIFICATION v1.0

Carbon UPI

India's open Digital Public Infrastructure for climate action verification.

The trust + verification rail underneath climate commerce — not another app. Modelled on UPI / ONDC / DigiLocker. Built for regulators, banks, and registries.

7-Layer DPI Stack

Modelled on UPI architecture. Each layer is independently operable and composable.

1
CIH — Composite Identity HashACTIVE

SHA-256 binding of verified identity + device + GPS + timestamp. Privacy-preserving — PII never stored.

POST /api/v1/cih/create
2
CDIF — Climate Data IngestionACTIVE

8-field schema for standardized climate activity data. Trust levels: HIGH (IoT/satellite), MEDIUM (SCADA), LOW (manual).

POST /api/v1/cdif/submit
3
MRV — Deterministic VerificationACTIVE

Methodology-specific emission calculation. AI assists anomaly detection — AI does NOT determine emissions.

POST /api/v1/mrv/verify
4
GIC — Green Impact CertificateACTIVE

Programmable climate proof artifact. NOT a carbon credit. Consumable by banks, governments, registries, insurers.

POST /api/v1/gic/issue
5
Registry InteroperabilityPLANNED

Adapters for BEE CCTS, Verra VCS, Gold Standard, CBAM, POSOCO.

/api/v1/gic/:id/registry
6
Public Transparency LedgerACTIVE

Any party can verify any GIC by ID. No authentication required. This is the public trust layer.

GET /api/v1/gic/:id
7
Governance & Open ProtocolPLANNED

Open protocol committee, methodology approval process, community governance.

Approved Methodology Registry

All emission calculations are deterministic and formula-based. AI assists anomaly detection — AI does NOT determine emissions.
