Turkish Airlines scores 24/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified July 2026.
That places Turkish Airlines joint 705th of 790 companies scored, and joint 11th of 23 in Airlines / Aviation.
Turkish Airlines' emissions have risen 19% year-on-year to 27.5 Mt CO₂e in 2023, driven by fleet expansion plans to 800 aircraft by 2033. No SBTi-validated targets, no absolute reduction pathway, and reliance on offsets with credible additionality concerns. ClientEarth and NGOs flagged greenwashing; offset projects include terminated schemes and biodiversity-questionable plantations.
