Bunbury City is an aluminium smelter in Australia. Its listed capacity is 841,323 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 #8 among 12 aluminium smelters in Australia. It emits about 1,103,605 t CO₂e a year from Climate TRACE. That is 2.4% of the CO₂e from the 30 facilities in Australia that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 37% below the national median for this sector.

In context: how this facility compares

At 841,323 t of alumina/aluminum, Bunbury City is below the median aluminium smelter in Australia (1,107,004 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 1.1M t CO₂e/yr (Scope 1), Bunbury City carries no domestic carbon price — and as a CBAM-covered product, its 1.1M t at the EU CBAM rate (€75/t) is €83.2M/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).
