Wenshan Alumina Refinery & Smelter — China

Aluminium Smelter in China. Approximate location 23.38214, 104.23403.

Aluminium SmelterChinaCO₂ estimate (modelled)

Wenshan Alumina Refinery & Smelter is an aluminium smelter in China. 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 Yunnan Aluminium Co Ltd. It emits about 1,899,520 t CO₂e a year from Climate TRACE. That is 0.07% of the CO₂e from the 1,485 facilities in China that have an emissions figure in IndustryAtlas.

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 1.9M t CO₂e/yr (Scope 1), Wenshan Alumina Refinery & Smelter carries no domestic carbon price — and as a CBAM-covered product, its 1.9M t at the EU CBAM rate (€75/t) is €143M/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).
