dMRV is digital monitoring, reporting and verification: measuring a carbon project with instruments and software rather than periodic manual survey, so the evidence behind a credit is captured continuously and can be checked against a public record.

What does CarbonMarketsHQ do?

CarbonMarketsHQ builds open source dMRV infrastructure for carbon markets: it digitizes registry methodologies, meters projects in the field, and publishes the resulting evidence so a credit can be traced from the device that made it to the registry that retired it.

Which registries and standards does the tooling work with?

The methodologies are digitized on Hedera Guardian and have been used with Gold Standard and Verra. The tooling is methodology-agnostic: a new pathway is another methodology digitized against the same stack.

Is any of this publicly verifiable?

Yes. 1,667 tCO2e were verified under Gold Standard project GS3838 with 1,250 tCO2e issued on 25 Mar 2026, and the digitized methodologies are published in the open Guardian methodology library.

Is the software open source?

Yes. The methodology implementations and tooling are published openly, including in the Hedera Guardian methodology library and at https://github.com/CarbonMarketsHQ.

02.0 / WHAT WE DO

We digitize methodologies, meter the field and publish the proof, so a carbon credit’s story can be checked by anyone, from the device that made it to the registry that retired it.

ONE RECORD, END TO END

03.0 / THE JOURNEY OF A CREDIT

From methodology PDF to retired credit.

Paper cannot be checked at the speed the climate needs. A methodology enters this pipeline as a document and comes out as a living system. What follows is one real tonne making that trip.

GATE 01
DIGITIZE
The rulebook becomes running code.
A methodology of a hundred pages and more compiles into executable code, with every parameter, equation and evidence requirement enforced by the engine that runs it. The compiled methodology is the artefact, so it travels to whichever stack a standard has chosen.
GATE 02
AUTHOR
The paperwork compiles out of the record.
A digitized methodology sets exactly what a project has to prove. Authoring agents draft the project design document, the monitoring report and the verifier pack against that specification, with every claim carrying the source file it came from.
GATE 03
MEASURE
Evidence arrives from the field.
Device telemetry from metered stoves, per-batch production records from biochar sites, and satellite models calibrated against permanent ground plots. Measurement starts at the source and streams in daily.
GATE 04
CERTIFY
Verification keeps pace with the data.
Quantification and policy execution run continuously, and the evidence pack an accredited auditor asks for assembles itself. Earthood checked this one. Gold Standard issued against that opinion, on an interim track that pays a project in months.
GATE 05
RECORD
Every credit stays publicly auditable.
The credits land on a public ledger and Atlas publishes each one’s journey, from the device data that earned it through to the account that retires it. Anyone can follow a single tonne the whole way back.

DOCUMENTS: PDD, MR, verifier pack
EVIDENCE: 3,254 devices, daily
VERIFIED: Earthood, Feb 2026
ISSUED: 1,250 tCO₂e, Mar 2026
RECORD: Hedera Guardian, public

On 25 Mar 2026, Gold Standard issued its first fully digital clean cooking carbon credits.

GS3838, the eCook programme in Bangladesh. Gold Standard set the rules and issued, ATEC ran the programme, Earthood audited and Hedera anchored the record. CarbonMarketsHQ led the methodology digitisation behind the issuance and built the public Atlas dashboard.

04.0 / PLATFORM OFFERINGS

Certification is becoming software. We run it across three pathways.

Clean cooking, restoration and biochar differ completely in how the physical thing gets measured. Each one has a project already on the ground, and each one runs on the same documentation layer underneath.

Clean cooking dMRV

Every stove reports its own use, every day.

DEVICE TELEMETRY90-DAY CYCLE

Over a billion people still cook on smoky, polluting fires. Clean-cooking projects change that, and metering makes the impact bankable. Data moves from the stove to verification on its own.

HOW IT WORKS

SOURCES IN, DOCUMENTS OUTEVERY CLAIM CITED

05.0 / CANON

THE PROJECT DOCUMENTATION SUITELIVE

One brain for a decade of paperwork.

Get months of documentation work done in minutes.

Every claim knows where it came from.

Certification runs on paperwork. A project description can run past 160 pages and its validation report past 190, a monitoring report comes back every year, and a single validation can close with more than thirty corrective action requests. The project outlives the people who wrote it, and the methodology changes underneath.

A carbon project is a graph pretending to be a document. The additionality argument is in a research PDF, the credit total is in a spreadsheet formula, the consent record is a photograph of an attendance register. Then one number is corrected and every document that quoted it is wrong by the afternoon.

Canon holds the whole project, from the methodology version in force to the answer given to a verifier eighteen months ago, and writes the official documents out of that record in the registry's own template. It is methodology-agnostic by design: the rules of a standard load as schemas, so a Gold Standard clean cooking programme, a Verra restoration project and a biochar pathway run side by side. Markdown and git underneath, readable by a person the day the software goes away.

An agent keeps the record current, and every decision stays with a person.

Planting schedule

Planting runs in two windows each year, set against the monsoon onset, with the nursery schedule working back from the second window.

The end date of the second window is recorded differently in two sources. Both are kept.

THE LIVING KNOWLEDGE BASE

Drop in a PDF, a spreadsheet or a photograph of an attendance register. The agent parses it and updates every page it touches.

EVERY CHANGE LOGGED

When a source file changes, the pages built on it flag stale, and the log records what changed and what it broke.

DOCUMENTS THAT COMPILE

Registry documents compile into the official template, and every remaining gap is flagged for a person to fill.

AN AUDIT TRAIL BY DEFAULT

Every figure resolves back to the file, page and date it came from, so a verifier gets an answer in one click.

THE PROJECT’S MEMORY

A deviation agreed in year three reappears in every report that follows it, with the reasoning still attached.

10,000 hectares of the Indo‑Burmese biodiversity hotspot, coming back.

Nagaland is losing forest cover faster than any other Indian state. Forest Futures brings 10,000 hectares of it back with 16 native species, on land the village councils own and govern, within reach of 200K+ people. We are co-proponent and technology partner, carrying the project alongside the communities who hold the land. It is our own project, and it runs our own nature-based dMRV stack, with 30 permanent plots where the satellite models meet a measuring tape.

Somebody outside the room has to be able to check it.

So we are writing the checking down, in the open, with the bodies that hold the rules.

Carbon markets run on trust, and trust needs methods people can read and numbers people can check. The methodologies we digitize are published as open reference implementations, and we write up the craft as we learn it.
