ArcelorMittal Barra Mansa steel plant — Brazil
Steel Plant in Brazil. Approximate location -22.52451, -44.19381.
Steel PlantBrazilCO₂ estimate (modelled)
ArcelorMittal Barra Mansa steel plant is a steel plant in Brazil. 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 ArcelorMittal Brasil SA. It emits about 445,433 t CO₂e a year from Climate TRACE. That is 0.32% of the CO₂e from the 130 facilities in Brazil that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1566462.

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 445k t CO₂e/yr (Scope 1), ArcelorMittal Barra Mansa steel plant carries no domestic carbon price — and as a CBAM-covered product, its 445k t at the EU CBAM rate (€75/t) is €33.6M/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).

Local climate
ArcelorMittal Barra Mansa steel plant sits in a humid subtropical climate zone (Köppen Cfa), at 22.5°S in the southern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1293 W/m² to ambient — roughly 0.99× 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.
