Scope 3 · Ontario manufacturers
Scope 3 reporting for Ontario manufacturers —
from your actual MTCs, fuel slips, and SAP exports.
Stop guessing Scope 3 with industry averages. VantageHSG ingests MTCs, LIMS assays, fuel slips, and SAP purchase orders to produce traceable Scope 1, 2, and 3 for Ontario steel, cement, auto parts, and chemical facilities. Bill C-59 and OEM ready.
Why Ontario manufacturers can't rely on spend-based Scope 3
Most Ontario industrial facilities still calculate Scope 3 using spend-based EEIO multipliers applied to AP ledger totals. That approach produces a number — but not one an OEM, bank, or verifier will accept under Bill C-59 or CBAM. When GM asks for the embedded carbon in a specific stamping, or when your lender requests CSDS-aligned climate data, they want primary operational data: which steel grade, which supplier batch, which fuel mix, which production routing. VantageHSG replaces the spreadsheet guesswork with a data pipeline that starts at the source document — mill test certificates, LIMS assays, SAP purchase orders, utility bills — and ends at a Scope 3 line item with full factor lineage and assumption disclosure.
What we ingest (and what we return)
Send us the documents your plant floor already produces. We handle OCR ingestion, unit normalization, and mass-balance reconciliation before applying the right emission factor for each material stream. For steel and foundries, that means iron ore, coking coal, ferroalloys, and scrap ratios. For automotive parts suppliers, it means per-part routing through stamping, welding, and coating lines. For plastics and chemicals, it means feedstock carbon vs. combustion split. Every output includes: the emission factor used (ECCC NIR, U.S. EPA EEIO, or supplier EPD), the version and publication date, the assumptions made, and the gaps flagged for verifier follow-up. You get Scope 1, 2, and 3 in one ledger — not three disconnected spreadsheets updated once a year.
Built for Ontario compliance pressure, not generic SaaS
Ontario manufacturers face a stacked compliance calendar: NPRI filing by June 1, federal OBPS carbon pricing on liable tonnes, Bill C-59 private right of action on environmental claims, CBAM declarations for EU-bound steel and cement, and OEM carbon questionnaires from Detroit automakers. Scope 3 is the connective tissue across all of these. VantageHSG is built in London, Ontario, with Ontario IESO grid factors, ECCC National Inventory Report combustion factors, and NPRI-aware peer benchmarking from 1,400+ public facility records. We know the difference between Hamilton blast-furnace route and Sault Ste. Marie EAF — and our emission factors reflect it.
How to start without a six-figure consulting engagement
You don't need a year-long implementation. Send one source document — a single MTC, fuel slip, or SAP extract — and we'll return a sample report showing factor lineage, assumptions, and gaps in 14 days. No obligation. If the pipeline proves fit, move to a 90-day paid pilot on one real facility with measurable success criteria: ingestion turnaround, mass-balance reconciliation rate, and report quality against your verifier's checklist. Starter plans begin at $299/month for single-facility Scope 1 and 2; Growth at $599/month adds full Scope 3 with Bill C-59 compliance statements.
Why VantageHSG
Built for Ontario manufacturers — not retrofitted from generic SaaS.
- ✓ECCC National Inventory Report factors — version-pinned
- ✓Ontario IESO grid factors for Scope 2
- ✓U.S. EPA EEIO fallback with full disclosure
- ✓Immutable audit ledger — who changed what, when
- ✓NPRI-aware peer benchmarking from public data
Common questions
Do I need Scope 3 reporting if I'm only an NPRI reporter?
NPRI covers direct releases, but OEM customers, banks under CSDS, and EU CBAM rules increasingly require Scope 3. If you supply into automotive, construction, or export steel/cement, Scope 3 is already on your compliance calendar — even if NPRI doesn't ask for it explicitly.
Can you use our suppliers' EPDs instead of industry averages?
Yes. Where suppliers provide Environmental Product Declarations or primary emission data, we use them. Where they don't, we fall back to EEIO factors with full version-pinning and disclosure so verifiers see exactly what was assumed.
How is this different from hiring a carbon consultant?
A consultant produces an annual PDF snapshot. VantageHSG is continuous infrastructure: your documents flow in, the ledger updates, and every number stays traceable. The cost is a fraction of a $50K–$100K annual consulting engagement.
