01
Scope 3 is a black box
Purchased goods, upstream transport, and supply-chain emissions live in supplier invoices, MTCs, and LIMS data nobody touches. You report Scope 1 & 2 and stop there.
Carbon data infrastructure · Ontario
Ontario manufacturers:
turn messy facility documents into audit-ready carbon numbers.
“Audit-ready” means source-linked, factor-referenced, assumption-labeled, and gap-flagged — not a guarantee of auditor approval.
Send one MTC, fuel slip, utility bill, LIMS export, or SAP extract. We’ll return the factor used, assumptions made, source lineage, and the gaps an auditor or OEM will ask about.

Real output
One fuel slip becomes a traceable carbon record.
No estimates. No black boxes. This is the kind of lineage your auditor or OEM will actually accept.
Input
Diesel fuel slip — date, supplier, volume in litres, facility reference.
Extracted fields
4,872 L • Acme Fuels • Hamilton Plant 2 • Slip date 2025-03-12
Factor applied
ECCC National Inventory Report diesel factor (2024 v1.3) — 2.681 kg CO₂e per litre.
Calculation + output
4,872 L × 2.681 = 13.06 tCO₂e Scope 1. Ledger row includes factor version, source document ID, assumptions, and flagged gaps.
The sample report shows the full chain: every number back to the slip you sent.
The problem
You can't report what you can't measure.
We analyzed five of Ontario's largest steel, concrete, and auto-parts manufacturers. Every one had a Scope 3 problem. Every one used spreadsheets. None mentioned Bill C-59. The data infrastructure doesn't exist — so we're building it.
02
Bill C-59 is now enforceable
The Competition Act lets the Competition Bureau investigate and seek administrative monetary penalties for misleading environmental claims. Fines: up to $10M or 3% of worldwide revenue.
03
Consultants don't scale
Traditional carbon accounting costs $50K–$100K per facility per year and leaves you with an annual snapshot. Your data is still a mess the day they walk out.
Built for teams
Entire teams contribute. One ledger.
Operations uploads MTCs. AP forwards fuel slips. HR emails receipts. Everyone feeds the same shared inbox — with full uploader lineage for auditors.
Role-based access
Admin, data entry, read-only, and auditor roles — each with the right permissions.
Shared inbox
One central registry for every document that feeds your carbon ledger.
Email-forward ingest
Tenant-specific ingest address — forward bills without logging in.
The product
Three layers of carbon intelligence.
Start with the data pipeline. Add Scope 3 calculation. Layer on risk and compliance. Each tier compounds the value of the last.
Layer 1
Data infrastructure
The headless pipeline that ingests your raw operational data and normalizes it to a single carbon ledger. OCR for paper, APIs for ERP, read-only views for LIMS.
- AI extraction from MTCs, fuel slips, utility bills
- Moisture stripping & unit normalization
- Direct ERP integration (SAP, Epicor, SYSPRO)
- Immutable audit ledger with data lineage
Layer 2
Scope 3 calculation
The mass balance engine that turns your raw inputs into Scope 3 numbers — calculated from your own data, not estimated from industry averages.
- ECCC emission factors, applied automatically
- EEIO factors for purchased goods (Cat. 1)
- 15 GHG Protocol categories covered
- Source documents + factors + assumptions behind every number (Bill C-59 substantiation file)
Layer 3
Risk & compliance
Continuous monitoring of your carbon exposure — what lenders, auditors, and OEMs will see when they ask for primary data, and what to do about it.
- CBAM optimization (EU border carbon tax)
- Peer benchmarking (NPRI-facility level)
- Private verifier-ready reports
- OEM questionnaire response exports
Why now
Three regulatory tailwinds at once.
The market didn't exist in 2020. It exists now because three independent forces created a compliance crisis for Ontario's largest emitters — and most of them aren't ready.
Bill C-59
The Competition Act makes greenwashing a violation: the Competition Bureau can investigate and seek fines for unsubstantiated environmental claims. Fines of up to $10M or 3% of worldwide revenueapply to corporations.
For Ontario manufacturers:every carbon claim on your website, in your ESG report, or on a shipment now needs a defensible methodology. A snapshot from last year's consultant won't cut it.
CBAM
The EU's Carbon Border Adjustment Mechanism has applied since October 2023; full Phase 2 requirements are in force as of January 2026 for steel, cement, aluminium, fertilizers, electricity, and hydrogen exported to Europe.
For Ontario exporters: EU customs needs embedded-carbon numbers tied to your production data — not estimated — or your shipment carries the CBAM charge.
CSDS 1 & 2
CSDS 1 and CSDS 2 are voluntary today. They are becoming the common language that banks, auditors, and large OEM buyers use when they ask Canadian suppliers for climate data and Scope 3 numbers.
For Ontario manufacturers: the pressure arrives through lending covenants, customer questionnaires, and verifier expectations — even without a direct federal mandate yet.
Industries we serve
