RNB Cements Umiam Cement Plant — India
Cement Plant in India. Approximate location 25.66426, 91.91083.
Cement PlantIndiaCO₂ estimate (modelled)
RNB Cements Umiam Cement Plant is a cement plant in India. Its listed capacity is 438,000 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 RNB Cements Pvt Ltd. By capacity it ranks #76 among 88 cement plants in India. It emits about 146,545 t CO₂e a year from Climate TRACE. That is 0.03% of the CO₂e from the 297 facilities in India that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 8% below the national median for this sector.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-42547432.

In context: how this facility compares
At 438,000 t of cement, RNB Cements Umiam Cement Plant is below the median cement plant in India (2,750,000 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 147k t CO₂e/yr (Scope 1), RNB Cements Umiam Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 147k t at the EU CBAM rate (€75/t) is €11.0M/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
RNB Cements Umiam Cement Plant sits in a humid subtropical (dry winter) climate zone (Köppen Cwa), at 25.7°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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1328 W/m² to ambient — roughly 1.02× 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.
