Facility counts by sector, Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0).
Across the 6 Iceland industrial facilities with an estimated CO₂ figure (Climate TRACE), total emissions are about 2.6 Mt CO₂e/yr. The single largest emitter, Fjardaal aluminium plant (aluminum), accounts for about 29% of that. The biggest sectoral share comes from aluminum. Among facilities with a known operator, the top three — Alcoa Corp, Nordic Aluminum Co, Rio Tinto Ltd — account for roughly 71%. Most of these facilities sit in a temperate Köppen climate zone.
