Ryanair is the most polluting airline in the European Union based on verified emissions covered by the European Union Emissions Trading Scheme (EU ETS). In 2023, the Irish low-cost carrier's reported ETS emissions were 10.3 million metric tons of carbon dioxide equivalent (MtCO₂e) for flights within the European Union Economic Area.
All major airlines in the EU experienced dramatic emission reductions in 2020 due to outbreak of COVID-19 and its impacts on the aviation industry. Although total emissions from the most polluting airlines have increased since then, they have remained below pre-pandemic levels.
