Facility counts by sector, Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0).
Across the 7 New Zealand industrial facilities with an estimated CO₂ figure (Climate TRACE), total emissions are about 2.8 Mt CO₂e/yr. The single largest emitter, BlueScope New Zealand Steel Glenbrook (iron-and-steel), accounts for about 29% of that. The biggest sectoral share comes from iron-and-steel. Among facilities with a known operator, the top three — New Zealand Steel Ltd, New Zealand Aluminium Smelters, Methanex Corp — account for roughly 72%. Most of these facilities sit in a temperate Köppen climate zone.
Estimated CO₂e (modelled): Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0); climate: Köppen-Geiger (WorldClim). CC BY 4.0.
