Aegean Airlines discloses only FY2022 absolute Scope 1 emissions (1.13 Mt CO2e); Scope 3 is entirely unreported. The airline publishes intensity-only trajectory data without confirming absolute reductions despite 6% annual capacity growth. No SBTi validation, no net-zero commitment, and membership in trade groups actively opposing EU climate regulation.
