Boké Prefecture — Guinea
Aluminium Smelter in Guinea. Approximate location 11.00694, -14.45361.
Aluminium SmelterGuineaCO₂ estimate (modelled)
Boké Prefecture is an aluminium smelter in Guinea. Its listed capacity is 555,356 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. By capacity it ranks #2 among 3 aluminium smelters in Guinea. It emits about 1,160,546 t CO₂e a year from Climate TRACE. That is 37% of the CO₂e from the 4 facilities in Guinea that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673066.

In context: how this facility compares
At 555,356 t of alumina/aluminum, Boké Prefecture is around the median aluminium smelter in Guinea (555,356 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 1.2M t CO₂e/yr (Scope 1), Boké Prefecture carries no domestic carbon price — and as a CBAM-covered product, its 1.2M t at the EU CBAM rate (€75/t) is €87.5M/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
Boké Prefecture sits in a tropical savanna climate zone (Köppen Aw), at 11.0°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 corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1224 W/m² to ambient — roughly 0.94× 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.

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.
