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.
