Ryanair's emissions are rising sharply while it claims climate leadership. Absolute CO2 grew 80% since 2022; intensity targets mask this reality. The airline relies entirely on fossil jet fuel, has minimal SAF uptake beyond EU mandates, and CEO O'Leary publicly undermines the company's own net-zero strategy. Multiple regulatory bodies have found misleading climate claims.
