National Cement Mathatani Cement Plant — Kenya
Cement Plant in Kenya. Approximate location -1.4953, 37.05547.
Cement PlantKenyaCO₂ estimate (modelled)
National Cement Mathatani Cement Plant is a cement plant in Kenya. Its listed capacity is 1,700,000 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 National Cement Company Ltd. By capacity it ranks #1 among 2 cement plants in Kenya. It emits about 881,384 t CO₂e a year from Climate TRACE. That is 26% of the CO₂e from the 7 facilities in Kenya that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 43% above the national median for this sector.

In context: how this facility compares
At 1,700,000 t of cement, National Cement Mathatani Cement Plant is around the median cement plant in Kenya (1,700,000 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 881k t CO₂e/yr (Scope 1), National Cement Mathatani Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 881k t at the EU CBAM rate (€75/t) is €66.4M/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
National Cement Mathatani Cement Plant sits in a subtropical highland climate zone (Köppen Cwb), at 1.5°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 a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with heat / UV the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1301 W/m² to ambient — roughly 1.00× 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.
