CMC Tennessee steel plant — United States
Steel Plant in United States. Approximate location 35.97829, -83.95666.
Steel PlantUnited StatesCO₂ estimate (modelled)
CMC Tennessee steel plant is a steel plant in United States. Its listed capacity is 544,000 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 Commercial Metals Co. By capacity it ranks #48 among 49 steel plants in United States. It emits about 30,193 t CO₂e a year from Climate TRACE. Its CO₂ per unit of capacity is 94% below the national median for this sector.

In context: how this facility compares
At 544,000 t of steel, CMC Tennessee steel plant is below 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 30k t CO₂e/yr (Scope 1), CMC Tennessee steel plant carries no domestic carbon price — and as a CBAM-covered product, its 30k t at the EU CBAM rate (€75/t) is €2.3M/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).

Local climate
CMC Tennessee steel plant sits in a humid subtropical climate zone (Köppen Cfa), at 36.0°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 1357 W/m² to ambient — roughly 1.04× 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.
