Outao Cement Plant — Portugal
Cement Plant in Portugal. Approximate location 38.5016, -8.93616.
Cement PlantPortugalCO₂ estimate (modelled)
Outao Cement Plant is a cement plant in Portugal. 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 SECIL - Companhia Geral de Cal e Cimento SA. It emits about 835,160 t CO₂e a year from Climate TRACE. That is 5.6% of the CO₂e from the 29 facilities in Portugal that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32439043.

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 835k t CO₂e/yr (Scope 1), Outao Cement Plant carries €71.3M/yr of carbon at the full EU ETS price (€85/t CO₂). Free allocation phases out to 2034 (Reg. (EU) 2023/956), so today's bill is lower and rising toward this full-price figure.

Local climate
Outao Cement Plant sits in a hot-summer Mediterranean climate zone (Köppen Csa), at 38.5°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 corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1333 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.
