Home/Industries/Concrete & cement

Clinker ratio, kiln fuel, and embodied carbon per m³
calculated the way EPDs expect it.

Cement production is the third-largest industrial CO₂ source globally. In Ontario, the cement and ready-mix industry faces a unique pressure: the calcination CO₂ from clinker is unavoidable, but everything around it (kiln fuel mix, supplementary cementitious materials, transportation) is highly variable and highly verifiable. That's where VantageHSG lives.

Why concrete & cement reporting is hard.

We've worked with enough concrete & cementfacilities in Ontario to know the exact failure modes. Here's what trips people up.

!Challenge 01

Clinker ratio is the dominant variable

A 5% swing in clinker-to-cement ratio changes your per-tonne carbon footprint by ~3%. Most spreadsheets lose this granularity because the data lives in production supervisor notes, not ERP fields.

!Challenge 02

Moisture in alternative fuels is misallocated

When you burn RDF, tires, or biomass, the moisture content of the fuel doesn't emit CO₂ — but most emission calculators either ignore it or apply the wrong factor. The verifier will catch this.

!Challenge 03

Embodied carbon per m³ requires both the cement and the aggregate

For EPDs and LEED submissions, you need a per-m³ number that includes SCMs, water, admixtures, and transport — not just the cement plant's Scope 1.

Our Solution

Built for concrete & cement — 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.

Clinker ratio from production logs, not blended averages

We pull your daily kiln production and cement mill logs to calculate the actual clinker-to-cement ratio per product, per period — not a quarterly average applied retroactively.

Moisture-corrected fuel emissions

Every fuel slip is moisture-stripped and unit-normalized before the emission factor is applied. Biomass fuels are reported separately and netted only where methodology permits.

EPD-ready per-m³ and per-tonne numbers

Output is structured to match ISO 14025 / 21930 / 15804 expectations for Environmental Product Declarations — including A1–A3 modules and the full data lineage.

Methodology Scope

The factors that matter for concrete & cement.

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.

Clinker calcination CO₂ (CaCO₃ → CaO + CO₂)
Kiln fuel: natural gas, pet coke, coal, RDF, tires
Supplementary cementitious materials (slag, fly ash, silica fume)
Ontario IESO grid factors
Upstream transport (Cat. 4) for raw materials
NAICS Coverage

Built for the rest of Ontario's largest emitters too.
