Zunyi Prefecture City — China
Aluminium Smelter in China. Approximate location 28.1676, 107.08654.
Aluminium SmelterChinaCO₂ estimate (modelled)
Zunyi Prefecture City is an aluminium smelter in China. Its listed capacity is 2,760,401 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 #11 among 81 aluminium smelters in China. It emits about 3,745,312 t CO₂e a year from Climate TRACE. That is 0.14% of the CO₂e from the 1,485 facilities in China that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 35% below the national median for this sector.

In context: how this facility compares
At 2,760,401 t of alumina/aluminum, Zunyi Prefecture City is well above the median aluminium smelter in China (450,000 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 3.7M t CO₂e/yr (Scope 1), Zunyi Prefecture City carries no domestic carbon price — and as a CBAM-covered product, its 3.7M t at the EU CBAM rate (€75/t) is €282M/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
Zunyi Prefecture City sits in a humid subtropical climate zone (Köppen Cfa), at 28.2°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 1348 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.
