Deschambault aluminium plant — Canada
Aluminium Smelter in Canada. Approximate location 46.69378, -71.94636.
Aluminium SmelterCanadaCO₂ estimate (modelled)
Deschambault aluminium plant is an aluminium smelter in Canada. Its listed capacity is 290,000 t of alumina/aluminum. 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 Alcoa Aluminerie de Deschambault. By capacity it ranks #7 among 11 aluminium smelters in Canada. It emits about 616,290 t CO₂e a year from Climate TRACE. That is 0.88% of the CO₂e from the 127 facilities in Canada that have an emissions figure in IndustryAtlas.

In context: how this facility compares
At 290,000 t of alumina/aluminum, Deschambault aluminium plant is around the median aluminium smelter in Canada (314,000 t of alumina/aluminum). 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 616k t CO₂e/yr (Scope 1), Deschambault aluminium plant carries no domestic carbon price — and as a CBAM-covered product, its 616k t at the EU CBAM rate (€75/t) is €46.4M/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
Deschambault aluminium plant sits in a warm-summer humid continental climate zone (Köppen Dfb), at 46.7°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 thermal cycling the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1461 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.
