Nova Chemicals, Geismar,La. — United States
Petrochemical in United States. Approximate location 30.2042, -91.0225.
PetrochemicalUnited StatesCO₂ estimate (modelled)
Nova Chemicals, Geismar,La. is a petrochemical plant in United States. Its listed capacity is 885,000 t of ethylene. Petrochemical plants crack hydrocarbons at very high temperatures to produce ethylene, propylene and other building-block chemicals — one of the most heat-intensive industrial processes. It is operated by NOVA Chemicals Corp. By capacity it ranks #16 among 26 petrochemical plants in United States. It emits about 1,123,510 t CO₂e a year from Climate TRACE. That is 0.20% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-18648333.

In context: how this facility compares
At 885,000 t of ethylene, Nova Chemicals, Geismar,La. is below the median petrochemical plant in United States (1,134,000 t of ethylene). Subsector: petrochemical-steam-cracking. As petrochemical plant, it requires high process heat (typically 300–800°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Petrochemical plants crack hydrocarbons at very high temperatures to produce ethylene, propylene and other building-block chemicals — one of the most heat-intensive industrial processes.

Local climate
Nova Chemicals, Geismar,La. sits in a humid subtropical climate zone (Köppen Cfa), at 30.2°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 1302 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.
