// What it does

An evidence ledger, not another dashboard.

Every number in CarbonSKU is bound to the documents, factors, and assumptions it came from. Auditors get an unbroken chain. Your team gets a workflow.

EVIDENCE LOCKER

Tamper-evident records, by entity.

Manifests, POs, supplier PCFs, utility bills, certifications, factors, and calculation snapshots — hashed, versioned, and linked to the SKUs they back.

ACTION QUEUE

Carbon as inbox, not spreadsheet.

Grouped work — needs review, evidence gaps, supplier follow-up, calculation anomalies, audit tasks — each with severity, due date, owner, and a draft action ready to approve.

CALCULATION LINEAGE

Every kg traceable in one screen.

Activity data → emission factors → methodology → result. Each step hashed and replayable, so you can defend a number a quarter — or a year — later.

// How it works

From source documents to audit-ready packets — in days, not quarters.

CarbonSKU ingests what you already have, calculates against your chosen methodology, and produces evidence chains your auditor will sign off on.

01 · INGEST

Connect your operational stack.

SAP / Oracle / NetSuite, EDI carriers, supplier portals, OCR for the rest.

sap.sync · 0 diffsmaersk.edi · 1 dococr.queue · 3 docs
02 · CALCULATE

Activity data + factors + methodology.

// Built for

One workspace · five jobs.

Sustainability, procurement, ops, finance, and assurance — each with a view that respects what they actually do all day.

Sustainability lead

Defend the number to the auditor.

Evidence completeness, methodology version, anomaly explanations — already prepared.

Sustainable procurement

Decide supplier, lane, and mode with carbon priced in.

Simulations that show carbon, cost, lead-time, and confidence in one view.

Ops & data engineer

Wire it into your stack without a 6-month integration.

Ingestion, ERP sync, OCR queue, agent runs, failed jobs — visible and replayable.

“For the first time, the number on the disclosure has a documented chain back to a purchase order and a utility bill. The auditor stopped sending us spreadsheets.”
