AZA Colina steel plant — Chile
Steel Plant in Chile. Approximate location -33.29473, -70.72814.
Steel PlantChileCO₂ estimate (modelled)
AZA Colina steel plant is a steel plant in Chile. Its listed capacity is 520,000 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 Aceros AZA SA. By capacity it ranks #2 among 2 steel plants in Chile. It emits about 25,308 t CO₂e a year from Climate TRACE. That is 0.32% of the CO₂e from the 20 facilities in Chile that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 95% below the national median for this sector.

In context: how this facility compares
At 520,000 t of steel, AZA Colina steel plant is below the median steel plant in Chile (1,085,519 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 25k t CO₂e/yr (Scope 1), AZA Colina steel plant carries no domestic carbon price — and as a CBAM-covered product, its 25k t at the EU CBAM rate (€75/t) is €1.9M/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
AZA Colina steel plant sits in a warm-summer Mediterranean climate zone (Köppen Csb), at 33.3°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 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 1350 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.
