Icelandair discloses carbon operations and waste data but reports absolute emissions rising 4.8% while promoting only intensity improvements. Scope 3 accounting is severely incomplete, SAF uptake is unquantified, and climate targets are intensity-only without absolute reductions. Trade association membership in IATA and A4E undermines stated climate ambition.
Icelandair scores 29/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified July 2026.
That places Icelandair joint 753rd of 1,023 companies scored, and 3rd of 23 in Airlines / Aviation.
