Facility counts by sector, Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0).
Across the 15 Austria industrial facilities with an estimated CO₂ figure (Climate TRACE), total emissions are about 17.6 Mt CO₂e/yr. The single largest emitter, Voestalpine Stahl Linz steel plant (iron-and-steel), accounts for about 57% of that. The biggest sectoral share comes from iron-and-steel. Among facilities with a known operator, the top three — Voestalpine Stahl GmbH, OMV AG, Voestalpine Stahl Donawitz GmbH — account for roughly 83%. Most of these facilities sit in a temperate Köppen climate zone.
