Montana City Cement Plant — United States
Cement Plant in United States. Approximate location 46.54342, -111.92197.
Cement PlantUnited StatesCO₂ estimate (modelled)
Montana City Cement Plant is a cement plant in United States. Its listed capacity is 350,000 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 Ash Grove Cement Co. By capacity it ranks #30 among 32 cement plants in United States. It emits about 168,520 t CO₂e a year from Climate TRACE. That is 0.03% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 33% above the national median for this sector.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32439262.

In context: how this facility compares
At 350,000 t of cement, Montana City Cement Plant is below the median cement plant in United States (1,180,000 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 169k t CO₂e/yr (Scope 1), Montana City Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 169k t at the EU CBAM rate (€75/t) is €12.7M/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).
Measured CO₂: 323k t/yr — verified GHGRP (reporting year 2023) (91% above the modelled estimate). Modelled estimate 169k t/yr (Climate TRACE), high-confidence match, cross-checked via the measured-vs-modelled dataset (n=711).
Carbon price: EU CBAM €75/t · EU ETS €85/t, September 10, 2026, refreshed live via Carbon Hub. CO₂: measured (GHGRP RY2023), cross-checked vs Climate TRACE. Indicative carbon value, not the cash bill — free allocation applies; not compliance advice.

Local climate
Montana City Cement Plant sits in a cold semi-arid steppe climate zone (Köppen BSk), at 46.5°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 dust abrasion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1441 W/m² to ambient — roughly 1.11× 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.
