BlueScope North Star Steel plant — United States
Steel Plant in United States. Approximate location 41.56834, -84.04801.
Steel PlantUnited StatesCO₂ estimate (modelled)
BlueScope North Star Steel plant is a steel plant in United States. Its listed capacity is 3,034,000 t of steel. Steel plants burn coal in blast furnaces or use electric arcs to melt scrap; in both cases the molten metal must be kept above 1,500°C and transferred through extensive hot piping and vessels. It is operated by North Star BlueScope Steel Ltd. By capacity it ranks #10 among 49 steel plants in United States. It emits about 923,227 t CO₂e a year from Climate TRACE. That is 0.16% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 67% below the national median for this sector.

In context: how this facility compares
At 3,034,000 t of steel, BlueScope North Star Steel plant is well above the median steel plant in United States (907,000 t of steel). Subsector: iron-and-steel. As steel plant, it requires high process heat (typically 800–1500°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Steel plants burn coal in blast furnaces or use electric arcs to melt scrap; in both cases the molten metal must be kept above 1,500°C and transferred through extensive hot piping and vessels.

Carbon cost and Scope 1 emissions
At its reported 923k t CO₂e/yr (Scope 1), BlueScope North Star Steel plant carries no domestic carbon price — and as a CBAM-covered product, its 923k t at the EU CBAM rate (€75/t) is €69.6M/yr of exposure on EU-bound exports. CBAM share rises from 2.5% (2026) to 100% by 2034. No domestic carbon price — but cement, steel, aluminium, fertilizer and hydrogen exported to the EU face CBAM at €75/t (rising to 100% by 2034).
Measured CO₂: 442k t/yr — verified GHGRP (reporting year 2023) (52% below the modelled estimate). Modelled estimate 923k t/yr (Climate TRACE), high-confidence match, cross-checked via the measured-vs-modelled dataset (n=711).
Carbon price: EU CBAM €75/t · EU ETS €85/t, September 10, 2026, refreshed live via Carbon Hub. CO₂: measured (GHGRP RY2023), cross-checked vs Climate TRACE. Indicative carbon value, not the cash bill — free allocation applies; not compliance advice.

Local climate
BlueScope North Star Steel plant sits in a warm-summer humid continental climate zone (Köppen Dfb), at 41.6°N in the northern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with thermal cycling the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1403 W/m² to ambient — roughly 1.08× the loss at a 20 °C reference. Reference-surface calculation at a 150 °C surface from WorldClim climate normals (ASTM C680 / ISO 12241) — an indicative per-climate comparison, not a measurement of this site’s specific equipment. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
