San Marcos Cement Plant is a cement plant in Colombia. 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 Cementos San Marcos SAS. It emits about 185,156 t CO₂e a year from Climate TRACE. That is 2.2% of the CO₂e from the 20 facilities in Colombia that have an emissions figure in IndustryAtlas.

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 185k t CO₂e/yr (Scope 1), San Marcos Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 185k t at the EU CBAM rate (€75/t) is €14.0M/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).

In this site’s local climate, a bare 150 °C surface sheds about 1262 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.
