United Airlines scores 19/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places United Airlines joint 781st of 809 companies scored, and 22nd of 23 in Airlines / Aviation.
United's emissions are rising in absolute terms while the company pursues intensity-only targets and minimal renewable energy adoption. Absolute emissions grew 5.76% year-over-year to 52.3Mt in 2024. The airline's climate lobbying actively opposes decarbonization policy, and SAF comprises just 0.3% of fuel despite greenwashing claims.
