VAS Nghi Son Cast Iron and Steel plant — Vietnam
Steel Plant in Vietnam. Approximate location 19.33106, 105.78076.
Steel PlantVietnamCO₂ estimate (modelled)
VAS Nghi Son Cast Iron and Steel plant is a steel plant in Vietnam. Its listed capacity is 3,150,000 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 Nghi Son VAS Group JSC. By capacity it ranks #3 among 8 steel plants in Vietnam. It emits about 2,816,235 t CO₂e a year from Climate TRACE. That is 3.4% of the CO₂e from the 90 facilities in Vietnam that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1567175.

In context: how this facility compares
At 3,150,000 t of steel, VAS Nghi Son Cast Iron and Steel plant is around the median steel plant in Vietnam (2,525,000 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 2.8M t CO₂e/yr (Scope 1), VAS Nghi Son Cast Iron and Steel plant carries no domestic carbon price — and as a CBAM-covered product, its 2.8M t at the EU CBAM rate (€75/t) is €212M/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
VAS Nghi Son Cast Iron and Steel plant sits in a tropical monsoon climate zone (Köppen Am), at 19.3°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 an extreme marine/tropical environment (estimated ISO 9223 class CX — Extreme), with marine salt corrosion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1261 W/m² to ambient — roughly 0.97× 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.
