Finnair discloses emissions comprehensively but absolute emissions rose in 2025 despite intensity gains. SAF at 1.6% of fuel is regulatory-driven, not strategic. The airline's intensity-based SBTi target masks only 13% absolute reduction by 2033. Two greenwashing interventions in 2024 and heavy SAF dependency create credibility and delivery risk.
Finnair scores 33/100 (Below expectations) 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.
