Guidonia Cement Plant — Italy

Guidonia Cement Plant is a cement plant in Italy. Its listed capacity is 1,900,000 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 Buzzi SpA. By capacity it ranks #3 among 16 cement plants in Italy. It emits about 568,710 t CO₂e a year from Climate TRACE. That is 1.4% of the CO₂e from the 70 facilities in Italy that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 17% below the national median for this sector.

Measured and modelled emissions reconciliation

This facility is linked to EUTL ID IT_442 for reporting year 2023. The official source reports 383,770 t CO2; Climate TRACE models 568,710 t CO2e.

Limits of this comparison

• Measured CO2 and modelled CO2e are not identical accounting constructs.
• The crosswalk is an entity match, not proof that reporting boundaries are identical.
• The reporting year is shown explicitly and values are not extrapolated to the current year.

In context: how this facility compares

At 1,900,000 t of cement, Guidonia Cement Plant is well above the median cement plant in Italy (1,300,000 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.

Local climate

Guidonia Cement Plant sits in a humid subtropical climate zone (Köppen Cfa), at 42.0°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 corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1342 W/m² to ambient — roughly 1.03× 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.
