New · Puro.earth-aligned biochar MRV

Turn every batch of biochar into a verifiable carbon credit.

Biochar Systems UK gives producers and admins one platform to record biomass sources, run audit-ready batches, and issue carbon credits — without the spreadsheets.

What we do

The MRV foundation purpose-built for biochar.

Existing MRV tools are built for energy or forestry. Biochar Systems UK is built for the actual workflow of a biochar producer — from feedstock to issued credit.

Source to sink, on one timeline.

Capture biomass origin, sustainability evidence, pyrolysis parameters, and shipment data — each event timestamped and immutable.

Reviews that scale with you.

Producers submit, admins approve, auditors verify. State machine guarantees every batch follows the same airtight workflow.

Numbers your buyers can trust.

Carbon factors are versioned and snapshot on each credit. Every tCO₂e is traceable back to the batch and the methodology that produced it.

Built for audits

Every change, every actor, every minute — captured.

Producers can't edit a batch after submission. Admins can't change a methodology after a credit is issued. The trail is append-only and ships with every certificate.

  • Append-only event log per batch (who · what · when · why)
  • Versioned carbon factors snapshotted on every credit
  • Signed certificate PDFs ready to send to buyers
  • Role-scoped Postgres RLS — defence in depth

How it works

From feedstock to credit, in three steps.

No more spreadsheets, no more reconciling versions. The platform keeps the workflow honest.

01

Register feedstock

Producer logs biomass source, origin, sustainability docs. Photos and certificates attach to the source — not the batch.

02

Run the batch

Pyrolysis parameters, mass produced, lab analysis. Each field is validated; each upload is hashed and stored.

03

Earn the credit

Admin reviews → approves → a credit is issued under the active methodology version. Buyer-ready certificate generated automatically.

Methodology

Aligned with Puro.earth biochar methodology — versioned forever.

We don't reinvent the carbon maths. We implement the peer-reviewed methodology your auditor already knows, snapshot its parameters at the moment of issuance, and keep that snapshot attached to every credit you ever sell.

FAQ

Questions buyers ask us.

Don't see yours? Email hello@biocharsystems.co.uk — we usually reply same day.

Do you issue the carbon credits yourselves?
We issue credits inside the platform under the active methodology version, and prepare everything an external registry (Puro.earth, Verra) needs for listing. Registry-side issuance happens with our partners.
How do you handle methodology changes?
Carbon factors are versioned in the database. Every credit is stamped with the exact factor version used at issuance — past credits are never silently re-priced.
Can my auditor see the source data?
Yes. We generate a read-only auditor view scoped to the batches in scope, with the full immutable event log and original document attachments.
Where is data stored?
EU-region Postgres with row-level security. Producer data is isolated by default; UK-GDPR data-processing terms apply.

Stop selling carbon credits on trust. Start selling them on proof.
