Straumsvik aluminium plant — Iceland
Aluminium Smelter in Iceland. Approximate location 64.04345, -22.0325.
Aluminium SmelterIcelandCO₂ estimate (modelled)
Straumsvik aluminium plant is an aluminium smelter in Iceland. Aluminium smelters use large electric currents to refine alumina into molten aluminium above 900°C, and the hot metal must flow through crucibles and casting equipment. It is operated by Rio Tinto Ltd. It emits about 432,548 t CO₂e a year from Climate TRACE. That is 16% of the CO₂e from the 6 facilities in Iceland that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673098.

In context: how this facility compares
Subsector: aluminum. As aluminium smelter, it requires high process heat (typically 600–900°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Aluminium smelters use large electric currents to refine alumina into molten aluminium above 900°C, and the hot metal must flow through crucibles and casting equipment.

Carbon cost and Scope 1 emissions
At its reported 433k t CO₂e/yr (Scope 1), Straumsvik aluminium plant carries €36.9M/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
Straumsvik aluminium plant sits in a subpolar oceanic climate zone (Köppen Cfc), at 64.0°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 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 1451 W/m² to ambient — roughly 1.12× 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.
