Quality & integrity

Four tiers. One commitment.

Every CRIOS token carries a tier badge based on the integrity of its underlying source. Tier 0 is modeled and cannot be retired; retirement requires at least Tier 1 metered data.

Tier 0

Tier 0 — Modeled — not retirable

Modeled. Estimated from installed capacity and irradiation data while metering is being proven. Not retirable.

Example

12 kWp rooftop in Sete Lagoas, MG · output estimated from installed capacity and regional irradiation data · no meter yet connected · not eligible for retirement.

Tier 1

Tier 1 — Metered

Metered. Generation data captured from the plant via Karbera, with an official grid displacement factor applied.

Example

12 kWp solar in Sete Lagoas, MG · 1,500 kWh metered via Karbera · 0.3271 tCO₂/MWh official Brazil grid displacement factor · 0.491 tCO₂ (testnet, pilot).

Tier 2

Tier 2 — Programme-issued

Programme-issued. Issued under an external programme's methodology with third-party verification.

Example

Credit issued under an external programme's own methodology and third-party verification, then bridged into CRIOS with the issuing programme's record preserved.

Tier 3

Tier 3 — Legacy

Legacy. Pre-existing credits ported into CRIOS with provenance preserved.

Example

Pre-existing vintage credit ported into CRIOS with original issuance metadata preserved · clearly labeled as legacy.

The bar we hold

What CRIOS will never do.

Retire modeled credits

Tier 0 (modeled) tokens are estimates, not measurements. They are never eligible for retirement.

Co-mingle categories

Renewable, efficiency, mobility, forestry, and capture tokens are never pooled into a single 'carbon' instrument.

Issue without methodology

Every category requires a published, versioned methodology before any token is minted.

Overstate activity

Illustrative and preview data is always labelled as such. Nothing on testnet is presented as settled.

Methodology library

Published. Versioned. Public.

Auditors

Independent verification.

CRIOS intends to engage independent auditors to verify methodology adherence, mint integrity, and retirement accuracy as the pilot matures. Audit firms will be announced ahead of the first annual report.
