Gerdau Midlothian Steel Mill — United States
Steel Plant in United States. Approximate location 32.45876, -97.03658.
Steel PlantUnited StatesCO₂ estimate (modelled)
Gerdau Midlothian Steel Mill is a steel plant in United States. 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 Gerdau Ameristeel Corp. It emits about 83,254 t CO₂e a year from Climate TRACE. That is 0.01% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1567112.

Limits of this comparison
- Measured CO2 and modelled CO2e are not identical accounting constructs.
- The crosswalk is an entity match, not proof that reporting boundaries are identical.
- The reporting year is shown explicitly and values are not extrapolated to the current year.

In context: how this facility compares
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 83k t CO₂e/yr (Scope 1), Gerdau Midlothian Steel Mill carries no domestic carbon price — and as a CBAM-covered product, its 83k t at the EU CBAM rate (€75/t) is €6.3M/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: 273k t/yr — verified GHGRP (reporting year 2023) (228% above the modelled estimate). Modelled estimate 83k 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
Gerdau Midlothian Steel Mill sits in a humid subtropical climate zone (Köppen Cfa), at 32.5°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 humidity / wetness the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1315 W/m² to ambient — roughly 1.01× 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.
