Process vs. combustion emissions, feedstock carbon tracking, and MECP EPS compliance.
Plastics and chemical facilities in Ontario face a unique accounting problem: their emissions come from both combustion (boilers, process heaters) and process chemistry (feedstock cracking, polymerization off-gas). These need to be reported separately for NPRI, MECP EPS, and Bill C-59 purposes. VantageHSG does this split automatically from your operating data.
The challenges
Why plastics & chemicals reporting is hard.
We've worked with enough plastics & chemicalsfacilities in Ontario to know the exact failure modes. Here's what trips people up.
Process vs. combustion split is a manual exercise
NPRI and MECP require process emissions (e.g. ethylene off-gas, CO₂ from feedstock) to be reported separately from combustion emissions. Most plants compute this in Excel, once a year, with errors.
Feedstock carbon is controversial
Does the carbon in a polyethylene pellet count as Scope 1 if it never leaves the polymer? GHG Protocol says no for most plastics — but the verifier wants to see the methodology regardless.
MECP EPS adds an Ontario-specific reporting layer
The Ministry of Environment's EPS program has its own emission factors, its own facility thresholds, and its own reporting cadence. Getting this wrong delays your facility permit.
How VantageHSG handles it
Built for plastics & chemicals — 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.
Automatic process / combustion split
We tag every emission source as process, combustion, or fugitive, and route it to the right regulatory line. NPRI, MECP, and the federal OBPS all see the same source data, formatted per their spec.
Feedstock carbon tracking with full disclosure
We report feedstock carbon as Scope 1 only where methodology requires (e.g. carbon black, certain fluorochemicals). For polymers, we disclose the embedded carbon and the GHG Protocol reasoning.
MECP EPS-ready output
Submitting to the Ministry? We produce the EPS-format workbook with the right facility thresholds, the right verification statement, and the right signatures.
Emission factors we apply
The factors that matter for plastics & chemicals.
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.
- ●Natural gas (process & combustion)
- ●Feedstock (ethylene, propylene, styrene)
- ●Electricity (Ontario IESO)
- ●Process emissions (CO₂, CH₄, N₂O, HFCs)
- ●Resin and additive purchases (Cat. 1)
