The standards bodyfor the ocean.

The Marine Conservation Credits programme develops methodologies, registers projects and issues serialised conservation credits for marine ecosystems. Every future issuance requires independent third-party validation and verification; no credit has been issued yet. Monitored monthly from orbit, and contribution-first by design.

02 · Credit categories
Mangrove forest
MCC-CC

Blue carbon

Mangrove, seagrass and salt-marsh projects quantified for carbon sequestered in marine soils and biomass, under IPCC Tier 2/3 approaches and the 2013 Wetlands Supplement.

Reef ecosystem
Co-benefit label

Verified co-benefits

One credit carrying a separately verified co-benefit label, where a project has both carbon and biodiversity outcomes. A co-benefit attaches to a unit; it is not a unit of its own (the former MCC-HYB is abolished, FD-2026-09-03).

Marine wildlife
MCC-MCU

Conservation units

Conservation outcomes quantified independently of carbon: biodiversity and habitat, protected-area management, and pollution prevention such as ghost-gear recovery (F04, MCC-M008).

03 · Credit lifecycle

From project design to public verification

Nine stages across three governance bands. Nothing is self-certified: no credit is issued without a third-party verification opinion, and every serial is publicly checkable.

04 · The project register

From submission to issuance

The register lists projects from submission onward. Registration and issuance follow independent validation, verification and governance approval, and every entry links to its full public record.

The register is empty. Projects appear here from submission onward.

05 · Continuous monitoring

Monitored from orbit, verified in the field

Project boundaries are observed monthly via Sentinel-2. NDVI, NDWI and habitat-cover indices are written to the registry; anomalies route to expert review under the MCC-700 reversal framework. Satellites do not replace fieldwork — sediment coring, biomass sampling and dive surveys remain mandatory, and every issuance still requires an accredited third-party opinion.

06 · Integrity by design
01

Independent verification

Validation and issuance require an opinion from an accredited VVB under ISO 14065. Self-certification is not permitted under any methodology.

02

Public by default

Project Design Documents, validation and verification reports and issuance records are public registry documents.

03

Buffer pool

A project-specific buffer share, set by risk assessment within the band the Buffer Pool Management Policy prescribes, is withheld at issuance to absorb reversal risk and released only against sustained monitoring performance.

04

Serialisation and lineage

Every credit carries a serial with a Luhn check digit and a permanent issuance and retirement record. Illegal state changes are rejected at the data layer.

05

FPIC safeguards

Free, prior and informed consent, indigenous rights and equitable benefit-sharing are mandatory requirements, screened during validation.

06

Contribution-first claims

No offsetting, neutrality or net-zero claims against MCC retirements. Permitted language is published in the Claims Policy and enforced at retirement.
