How verification is structured
One claim, four accountable layers.
A methodology is not a single check — it is a chain of responsibility from the scientific basis to independent assurance.
- 01
Scientific basis
Methodology
Defines the environmental claim and the science behind it.
What the result means
- 02
Verification specification
MvF
Translates the basis into scope, evidence, rules, formulas and escalation criteria.
What must be checked
- 03
Executable application
MvA
Applies the approved framework as deterministic open-source rule processors.
How checks are executed
- 04
Independent assurance
Auditors + VVBs
Reviews facilities, framework fidelity and the digital evidence package.

Claim boundary
What must be true before issuance.
The claim
Organic waste — biowaste — can be certified as recycled when its eligibility, mass, custody and composting evidence pass the published verification rules.
- Material eligibility
- MassID type, subtype, unit and value meet the framework requirements.
- Participants
- Generator, hauler, processor, recycler and integrator roles are identified as required.
- Operational evidence
- Weighing, sorting, transport, drop-off and recycled events are checked.
- Locations and manifests
- Accredited addresses and required transport or recycling documents are matched.
- Final mass
- The verified recycling outcome is quantified from the recorded material evidence.
- Integrity controls
- Uniqueness and collision rules prevent double counting or conflicting issuance.
Verified output
Evidence becomes a public result.
The result is not asserted — it is the output of evidence that already passed every rule.
Inspect every layer
Public by design. Technical by choice.
