Kayong Utara Regency — Indonesia
Aluminium Smelter in Indonesia. Approximate location -1.36063, 109.39761.
Aluminium SmelterIndonesiaCO₂ estimate (modelled)
Kayong Utara Regency is an aluminium smelter in Indonesia. Its listed capacity is 158,673 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 Indonesia. It emits about 331,585 t CO₂e a year from Climate TRACE. That is 0.46% of the CO₂e from the 53 facilities in Indonesia that have an emissions figure in IndustryAtlas.

In context: how this facility compares
At 158,673 t of alumina/aluminum, Kayong Utara Regency is around the median aluminium smelter in Indonesia (158,673 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 332k t CO₂e/yr (Scope 1), Kayong Utara Regency carries no domestic carbon price — and as a CBAM-covered product, its 332k t at the EU CBAM rate (€75/t) is €25.0M/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
Kayong Utara Regency sits in a tropical rainforest climate zone (Köppen Af), at 1.4°S in the southern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1227 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.
