Trust and integrity for the carbon market.
A scientific, public platform for registering carbon credits, operated by the Federal University of Paraíba through LAViD, with a public audit trail and traceability from issuance to retirement.
Every certificate, fully evidenced.
A public register of every certificate issued by certification bodies. Every issuance, transfer and retirement is traceable, evidenced and dated — forming a complete, verifiable chain of custody.
Published evidence
The data and documents behind every certificate are public — from the evidence checklist to the fields the methodology declares. Download, review and audit at any time.
Complete traceability
Every certificate is followed from issuance through transfer to retirement, with dated events each carrying its own manifest, verifiable by self-check. One chain of custody for every participant.
Frictionless operation
Certification bodies submit projects, register certificates, transfer and retire them through the web interface or the partner API — no re-keying, and idempotent writes.
The Registry's commitments
Neutrality
The Registry does not measure, does not recalculate methodologies and does not judge technical merit. It checks evidence, verifies geographic overlap and keeps the public ledger. It does not operate a buffer pool, and no third-party credit is consumed to cover a reversal.
Transparency by rule
Minutes, methodologies, projects and annual reports on the Transparency Portal. Every methodology goes through a 30-day public consultation. Open source code.
Integrity by self-check
Every event generates a manifest with its own digest. Recompute it and compare the result — that does not make the history tamper-evident, because the manifest and the digest live in the same database, and the Registry does not claim otherwise.
Process
From registration to retirement
Projects and certificates go through review with double approval. Refusals are always justified — nothing is rejected automatically.
Certification body registration
The certification body registers, submits its institutional data and goes through review and approval by the Registry.
Project submission
Geographic boundary in GeoJSON, descriptive content and photographs, under a methodology version — through the web interface or the API.
Review and double approval
Evidence checklist item by item, automatic geographic-overlap verification and checks against external registries. Two distinct people approve, always.
Certificate registration
Under the approved project, each certificate declares its volume in tCO2e, external serial, vintage period and initial holder, with the evidence its methodology requires.
The certificate's life
Transfers chained between holders and retirement — single and irreversible — published on the certificate's public timeline.
Governance
Who looks after the register's integrity
A structure built so that no decision rests on one person alone — and so that every one of them can be checked later.
Executive Governing Council
Has the final word. Meets every quarter, rules on appeals and publishes its minutes for anyone to read.
Scientific Council
Seven or more researchers, most from outside UFPB. This is who evaluates the science — and their opinions carry decision-making weight.
Executive Board
Runs day to day operations: technical review, the platform, compliance and administration — separate from whoever deliberates.
Standing Committees
Dedicated attention to what needs continuous oversight: methodologies, technology, audit, compliance and accreditation.
And one simple rule applies to everyone: whoever has a stake in a decision does not take part in it.
Ready to accredit your certification body?
Accreditation goes through review and approval by the Registry. Once approved, your team registers projects and certificates through the web interface or the partner API.
