ArcelorMittal Hunedoara steel plant — Romania
Steel Plant in Romania. Approximate location 45.73518, 22.91627.
Steel PlantRomaniaCO₂ estimate (modelled)
ArcelorMittal Hunedoara steel plant is a steel plant in Romania. 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 Hunedoara SA. It emits about 41,259 t CO₂e a year from Climate TRACE. That is 0.28% of the CO₂e from the 26 facilities in Romania that have an emissions figure in IndustryAtlas.

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 41k t CO₂e/yr (Scope 1), ArcelorMittal Hunedoara steel plant carries €3.5M/yr of carbon at the full EU ETS price (€85/t CO₂). Free allocation phases out to 2034 (Reg. (EU) 2023/956), so today's bill is lower and rising toward this full-price figure.

Local climate
ArcelorMittal Hunedoara steel plant sits in a warm-summer humid continental climate zone (Köppen Dfb), at 45.7°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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1400 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.
