North Nippon Muroran Works steel plant — Japan

Steel Plant in Japan. Approximate location 42.34182, 140.99791.

Steel PlantJapanCO₂ estimate (modelled)

North Nippon Muroran Works steel plant is a steel plant in Japan. Steel plants burn coal in blast furnaces or use electric arcs to melt scrap; in both cases the molten metal must be kept above 1,500°C and transferred through extensive hot piping and vessels. It is operated by Nippon Steel Corp. It emits about 2,191,669 t CO₂e a year from Climate TRACE. That is 1.3% of the CO₂e from the 105 facilities in Japan that have an emissions figure in IndustryAtlas.

In context: how this facility compares

Subsector: iron-and-steel. As steel plant, it requires high process heat (typically 800–1500°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Steel plants burn coal in blast furnaces or use electric arcs to melt scrap; in both cases the molten metal must be kept above 1,500°C and transferred through extensive hot piping and vessels.

Carbon cost and Scope 1 emissions

At its reported 2.2M t CO₂e/yr (Scope 1), North Nippon Muroran Works steel plant carries no domestic carbon price — and as a CBAM-covered product, its 2.2M t at the EU CBAM rate (€75/t) is €165M/yr of exposure on EU-bound exports. CBAM share rises from 2.5% (2026) to 100% by 2034. No domestic carbon price — but cement, steel, aluminium, fertilizer and hydrogen exported to the EU face CBAM at €75/t (rising to 100% by 2034).

In this site’s local climate, a bare 150 °C surface sheds about 1415 W/m² to ambient — roughly 1.09× 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.
