Untervaz Cement Plant — Switzerland
Cement Plant in Switzerland. Approximate location 46.91711, 9.55104.
Cement PlantSwitzerlandCO₂ estimate (modelled)
Untervaz Cement Plant is a cement plant in Switzerland. 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 Holcim (Schweiz) AG. It emits about 356,766 t CO₂e a year from Climate TRACE. That is 16% of the CO₂e from the 21 facilities in Switzerland that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32437353.

In context: how this facility compares
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 357k t CO₂e/yr (Scope 1), Untervaz Cement Plant carries €30.4M/yr of carbon at the full Swiss ETS (EU-linked) price (€85/t CO₂). Free allocation phases out to 2034 (Reg. (EU) 2023/956), so today's bill is lower and rising toward this full-price figure.

Local climate
Untervaz Cement Plant sits in a tundra climate zone (Köppen ET), at 46.9°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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with thermal cycling the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1435 W/m² to ambient — roughly 1.10× 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.
