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. Fees pay for the review, never the result. Last verified July 2026.
That places Icelandair joint 634th of 847 companies scored, and 3rd of 23 in Airlines / Aviation.
Where Icelandair sits among airlines / aviation peers.
Among the 23 major airlines / aviation brands we've scored, Icelandair sits 3rd of 23.
Its three lowest-scoring questions, and what the evidence didn't show.
Only 89 tCO₂e Scope 3 reported in 2024, covering waste streams alone (1 of 15 GHG Protocol categories).
Primary target (50% CO₂/OTK reduction by 2030) is intensity-only, not absolute.
No TNFD disclosure or formal biodiversity assessment.
