Semen Padang Cement Plant — Indonesia
Cement Plant in Indonesia. Approximate location -0.94757, 100.47014.
Cement PlantIndonesiaCO₂ estimate (modelled)
Semen Padang Cement Plant is a cement plant in Indonesia. Its listed capacity is 8,800,000 t of cement. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length. It is operated by PT Semen Padang. By capacity it ranks #3 among 16 cement plants in Indonesia. It emits about 3,162,884 t CO₂e a year from Climate TRACE. That is 4.4% of the CO₂e from the 53 facilities in Indonesia that have an emissions figure in IndustryAtlas.

In context: how this facility compares
At 8,800,000 t of cement, Semen Padang Cement Plant is well above the median cement plant in Indonesia (4,300,000 t of cement). Subsector: cement. As cement plant, it requires high process heat (typically 800–1400°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length.

Carbon cost and Scope 1 emissions
At its reported 3.2M t CO₂e/yr (Scope 1), Semen Padang Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 3.2M t at the EU CBAM rate (€75/t) is €238M/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
Semen Padang Cement Plant sits in a tropical rainforest climate zone (Köppen Af), at 0.9°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 1258 W/m² to ambient — roughly 0.97× 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. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).
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.
