CHE-Visp_ammonia — Switzerland

CHE-Visp_ammonia is a chemical plant in Switzerland. Its listed capacity is 47,016 t of chemical. Chemical plants produce a wide range of industrial and specialty chemicals, many requiring precise temperature control and sustained heat input for reactions and separations. It emits about 39,480 t CO₂e a year from Climate TRACE. That is 1.8% of the CO₂e from the 21 facilities in Switzerland that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 42% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-33999177.

In context: how this facility compares

At 47,016 t of chemical, CHE-Visp_ammonia is around the median chemical plant in Switzerland (47,016 t of chemical). Subsector: chemicals. As chemical plant, it requires high process heat (typically 100–500°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Chemical plants produce a wide range of industrial and specialty chemicals, many requiring precise temperature control and sustained heat input for reactions and separations.

Local climate

CHE-Visp_ammonia sits in a tundra climate zone (Köppen ET), at 46.1°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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with thermal cycling the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1529 W/m² to ambient — roughly 1.18× 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.
