Ryanair's 20.1 Mt CO₂e footprint rose 7.8% year-on-year, driven by capacity growth to 300 million passengers by 2034. SAF remains negligible (2% from January 2025, meeting regulatory minimum only). An upheld ASA greenwashing ruling, ACM warning on offset claims, and documented climate lobbying deterioration—including CEO rejection of 2050 net-zero—undermine stated targets.
