The state of Iran's industrial emissions
Across the 126 Iran industrial facilities with an estimated CO₂ figure (Climate TRACE), total emissions are about 123 Mt CO₂e/yr. The single largest emitter, Mobarakeh Steel Complex Isfahan (iron-and-steel), accounts for about 5% of that. The biggest sectoral share comes from cement. Among facilities with a known operator, the top three — National Iranian Oil Refining And Distribution Co, Mobarakeh Steel Co, Hengam Petrochemical Group — account for roughly 22%. Most of these facilities sit in a arid Köppen climate zone.
