Carbonstack

Digital MRV for smallholder carbon

From a farm boundary to a paid farmer, with every tonne explained.

Enrol farms, bring in the data you already have, estimate credits on each farm's own climate, review vintages with a second pair of eyes, and pay the people who did the work.

Enrol farms where they are

Draw a boundary on satellite imagery, walk it with a phone's GPS, or upload KML, GeoJSON, WKT or a spreadsheet. Every boundary is checked before it is saved.

Bring your existing records

Import thousands of farms, farmers, practice logs and soil lab results at once, with every row and every problem shown before anything is written.

An estimate for every farm

Each farm is quantified on its own climate and crop calendar under VM0051 (rice) or VM0047 (trees), with every generic assumption named.

Four-eyes review

Vintages move draft → review → approved → issued. Nobody approves their own submission, and every step is in an append-only log.

Farmers get paid

Split issued credits by each farm's contribution, approve, and record each payout against the farmer who earned it.

Built for audit

Per-organisation isolation enforced in the database, roles for field agents through reviewers, and a derivation behind every tonne.
