Blast furnace, EAF, and foundry emission accounting
calculated from your actual process data.
Ontario's integrated steel mills, EAF operators, and foundries are the largest single source of industrial Scope 1 emissions in the province. Bill C-59 and the federal carbon price make blast-furnace and EAF emission accounting a board-level risk — and Scope 3 from iron ore and coking coal is the largest piece most operators don't measure at all.
The challenges
Why steel & foundries reporting is hard.
We've worked with enough steel & foundriesfacilities in Ontario to know the exact failure modes. Here's what trips people up.
Scope 3 Category 1 is the blind spot
Iron ore, coking coal, and ferroalloy purchases are typically the largest Scope 3 line item — and the hardest to verify, because suppliers report inconsistently (or not at all).
Scrap ratio variability breaks flat emission factors
EAF operators know that emission intensity changes dramatically with scrap ratio, electricity source, and pig iron share. Industry-average factors can be off by 40% or more.
Bill C-59 exposure on low-carbon-steel claims
Any product-level 'green steel' claim — whether to GM, Ford, or in a sales deck — needs verified methodology, not a marketing department's interpretation of an industry average.
How VantageHSG handles it
Built for steel & foundries — not retrofitted.
Generic carbon accounting software treats every industry the same. VantageHSG knows the difference between blast furnace and EAF — and so do the emission factors we apply.
First-principles blast furnace and EAF mass balance
We model your actual process: hot metal production, slag rate, scrap ratio, electrode consumption. The result is a facility-specific emission factor that holds up to verifier scrutiny.
Supplier-specific Scope 3 with EEIO fallback
Send us your suppliers' EPDs and we'll use them. Where you don't have them, we fall back to U.S. EPA EEIO factors with full version-pinning and disclosure.
Per-grade and per-billet footprints for OEM customers
Need to tell GM or Ford what the embedded carbon is in a specific billet or coil? VantageHSG breaks the facility total down to the product level using your actual production routing.
Emission factors we apply
The factors that matter for steel & foundries.
VantageHSG pins every calculation to a specific version of ECCC, EEIO, and sector-specific sources. Verifiers see exactly which factor was used, when it was published, and why.
- ●Blast furnace gas & coke oven gas
- ●Sinter and pellet emission factors
- ●Iron ore (hematite, magnetite, taconite)
- ●Coking coal, PCI coal, electrode paste
- ●Ferroalloys (FeMn, FeSi, FeCr)
- ●Ontario IESO grid factors (hourly, where metering allows)
