Shinetsu, Plaquemine, La — United States

Shinetsu, Plaquemine, La is a petrochemical plant in United States. 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 Shinetsu. It emits about 634,751 t CO₂e a year from Climate TRACE. That is 0.11% 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-18648337.

Measured and modelled emissions reconciliation

This facility is linked to GHGRP ID 1004867 for reporting year 2023. The official source reports 1,050,183 t CO2; Climate TRACE models 634,751 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

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.

Capacity & CO₂-intensity comparison computed from Climate TRACE industrial facilities data; sector role based on engineering reference.

Local climate

Shinetsu, Plaquemine, La sits in a humid subtropical climate zone (Köppen Cfa), at 30.3°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 1304 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.
