Carbon accounting built for steel
Steelmaking is among the most carbon-intensive industrial processes on earth. Carbonix tracks every tonne — furnace to finished coil.
Steel's carbon problem, quantified
Integrated blast-furnace routes emit roughly two tonnes of CO2 per tonne of crude steel, driven by coking coal chemistry that no efficiency programme can eliminate; electric-arc and induction routes shift the burden to electricity, where grid emission factors decide the footprint. Steel sits in the first wave of EU CBAM, so product-level carbon intensity is now a commercial number in European negotiations.
A steel plant's inventory spans coke ovens, sinter plants, blast furnaces, basic oxygen furnaces or EAFs, rolling mills, captive power and a heavy logistics tail — each with distinct data sources and factors. Generic sustainability tools struggle; steel-specific accounting does not.
What Carbonix handles for steel plants
Furnace-level activity data, fuel analyses, electrode consumption, flux inputs and captured-gas accounting are collected and converted with process-appropriate methods. Product carbon intensity is allocated across routes and grades for CBAM and buyer disclosures, while plant-level totals feed BRSR and PAT documentation.
Reduction roadmaps model the levers that matter in steel: scrap ratio, fuel switching, waste-heat recovery, and grid decarbonisation effects on EAF routes.
Compliance your customers actually ask for
EU CBAM declarations, BRSR Core assurance, buyer scorecards and PAT energy targets draw from one audited dataset — consistent numbers, no re-work.
Frequently asked questions
+How much CO2 does steelmaking emit?
Integrated BF-BOF routes typically emit around two tonnes of CO2 per tonne of crude steel; scrap-based EAF routes are far lower in direct emissions, with the footprint shifting to purchased electricity and the grid mix behind it.
+Is steel covered by EU CBAM?
Yes — iron and steel are in CBAM's initial scope, including many downstream articles. Exporters need product-level embedded-emissions data, with default values penalising those who cannot supply verified numbers.
+Can Carbonix compute carbon intensity per product grade?
Yes. Facility activity data is allocated across production routes and products using documented, CBAM-compatible methods, giving you grade-level intensity for buyers and regulators.
