Portland Cement Plant — New Zealand
Cement Plant in New Zealand. Approximate location -35.80698, 174.33281.
Cement PlantNew ZealandCO₂ estimate (modelled)
Portland Cement Plant is a cement plant in New Zealand. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length. It is operated by Golden Bay Cement Co Ltd. It emits about 371,744 t CO₂e a year from Climate TRACE. That is 13% of the CO₂e from the 7 facilities in New Zealand that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1897602.

In context: how this facility compares
Subsector: cement. As cement plant, it requires high process heat (typically 800–1400°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length.

Carbon cost and Scope 1 emissions
At its reported 372k t CO₂e/yr (Scope 1), Portland Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 372k t at the EU CBAM rate (€75/t) is €28.0M/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).
