TYNDALL CARBON STANDARDS · AFRICA

The carbon standard that measures, not estimates.

Tyndall is a standards body and registry for instrument-verified carbon projects in Africa – metered clean cooking first, built to extend to any instrumentable activity.

What carbon markets can't prove

Most credits are assertions. Tyndall makes them evidence.

01

Estimated, not measured

Baselines and usage are assumed, sampled annually.

02

The 10% discount

A fudge factor replaced honesty about unmeasured usage.

03

Opaque by default

Buyers can’t reconstruct how a credit came to exist.

The founding rule
“If we cannot verify it with technology, it does not come onto our platform.”

Continuous instrument data, not an annual sample. Devices stream; the platform judges completeness and integrity; the auditor reviews a report built from the evidence.

How it works

From registration to retirement, every stage leaves a public record.

  1. 01
    RegisterDeveloper and project enter the registry with a public ID.
  2. 02
    Design (PDD)Project design document written against a Tyndall methodology.
  3. 03
    Public commentThe draft PDD is published. Comments and responses stay on record.
  4. 04
    ValidateAn independent auditor, appointed by Tyndall, checks the design.
  5. 05
    MonitorDevices stream signed readings continuously.
  6. 06
    VerifyThe auditor reviews a report built from the evidence.
  7. 07
    IssueSerialised credits are issued to the developer’s account.
  8. 08
    RetirePermanent. Produces the public certificate.

Purchase produces a receipt. Retirement is the only irreversible act – and the only one that produces a certificate.

PURCHASE →ReceiptCredits move to your account. They can be held or transferred.
RETIRE →CertificateSerials are closed permanently and published.
The engine

The Data Quality & Gap Engine.

Every reading is checked for signature, sequence and timing before it can count toward an issuance. Three rules decide what happens when data is missing.

RULE 1

A gap is data that arrived late past 90 days - not a device that went quiet.

RULE 2

No device is ever filled in from its own history.

RULE 3

Cohort inference is capped, deducted and disclosed per issuance.

How late data is treated · TYN-DEV-NG-11207days between reading and arrival
90 days0120
Same-day and late readings inside the window count in full.Arrived after 104 days: recorded as a gap, excluded from issuance.Days with no cooking report zero use. They are not a gap and are never filled.

Usage is measured, never assumed.

The platform

One platform running both halves of Tyndall – the rulebook and the ledger.

  • Run a live fleet and defend its data.
  • Issue, sell and retire.
  • Show an assessor an anchored audit trail, reconstructable years later.
