Alcoa Mosjøen — Norway
Metals Plant in Norway. Approximate location 65.84711, 13.19026.
Metals PlantNorwayCO₂ estimate (modelled)
Alcoa Mosjøen is a non-ferrous metals plant in Norway. Non-ferrous metals plants melt, refine and cast metals in furnaces and crucibles above their melting points. It emits about 425,000 t CO₂e a year from Climate TRACE. That is 3.0% of the CO₂e from the 46 facilities in Norway that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673190.

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
Subsector: other-metals. As non-ferrous metals plant, it requires high process heat (typically 400–1200°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Non-ferrous metals plants melt, refine and cast metals in furnaces and crucibles above their melting points.
Capacity & CO₂-intensity comparison computed from Climate TRACE industrial facilities data; sector role based on engineering reference.
What 425,000 t CO₂e a year looks like
This facility's estimated annual CO₂e (Climate TRACE, modelled) in everyday equivalents from the US EPA Greenhouse Gas Equivalencies calculator:

Carbon cost and Scope 1 emissions
At its reported 425k t CO₂e/yr (Scope 1), Alcoa Mosjøen carries €36.3M/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.
Measured CO₂: 439k t/yr — verified EUTL (reporting year 2023) (3% above the modelled estimate). Modelled estimate 425k t/yr (Climate TRACE), high-confidence match, cross-checked via the measured-vs-modelled dataset (n=711).
Carbon price: EU ETS €85/t · EU ETS €85/t, September 10, 2026, refreshed live via Carbon Hub. CO₂: measured (EUTL RY2023), cross-checked vs Climate TRACE. Indicative carbon value, not the cash bill — free allocation applies; not compliance advice.
Local climate
Alcoa Mosjøen sits in a subarctic (boreal) climate zone (Köppen Dfc), at 65.8°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 1489 W/m² to ambient — roughly 1.15× 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.
