Voestalpine Stahl Donawitz steel plant — Austria

Voestalpine Stahl Donawitz steel plant is a steel plant in Austria. Its listed capacity is 850,000 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 Voestalpine Stahl Donawitz GmbH. By capacity it ranks #2 among 2 steel plants in Austria. It emits about 1,335,721 t CO₂e a year from Climate TRACE. That is 7.6% of the CO₂e from the 15 facilities in Austria that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 69% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1566430.

Measured and modelled emissions reconciliation

This facility is linked to EUTL ID AT_13 for reporting year 2023. The official source reports 2,742,027 t CO2; Climate TRACE models 1,335,721 t CO2e.

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

At 850,000 t of steel, Voestalpine Stahl Donawitz steel plant is below the median steel plant in Austria (6,000,000 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.

Local climate

Voestalpine Stahl Donawitz steel plant sits in a warm-summer humid continental climate zone (Köppen Dfb), at 47.4°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 1428 W/m² to ambient — roughly 1.10× 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.
