Vallourec Star Youngstown steel plant — United States

Steel Plant in United States. Approximate location 41.12585, -80.68362.

Steel PlantUnited StatesCO₂ estimate (modelled)

Vallourec Star Youngstown steel plant is a steel plant in United States. Its listed capacity is 725,000 t of steel. 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 Vallourec Star LP. By capacity it ranks #37 among 49 steel plants in United States. It emits about 56,637 t CO₂e a year from Climate TRACE. Its CO₂ per unit of capacity is 92% below the national median for this sector.

In context: how this facility compares

At 725,000 t of steel, Vallourec Star Youngstown steel plant is below the median steel plant in United States (907,000 t of steel). 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 57k t CO₂e/yr (Scope 1), Vallourec Star Youngstown steel plant carries no domestic carbon price — and as a CBAM-covered product, its 57k t at the EU CBAM rate (€75/t) is €4.3M/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).
