Ryanair expects to pay 17% more in aviation taxes this year, with the figure rising to €630 million.
The projected rise from €540 million in 2018 equates to €4.12 per passenger, representing 11% of the carrier’s average fare.
The cost per ticket is calculated to rise from €3.82 last year.
The details of what the airline will be levied in 2019 have been made public “in order to dispel the myth that aviation does not pay environmental taxes”.
UK Air Passenger Duty is the highest air tax burden on Europe’s largest budget airline, estimated at €383 million this year – up by more than €50 million over 2018.
The airline will pay €630 million into the European Union’s emissions trading scheme.
Other annual European air taxes levies include €85 million in Germany, €6 in Austria and €5 in Scandinavia, according to Ryanair.
The airline revealed that its CO2 emissions in June were 66g per passenger kilometre.
Chief marketing officer Kenny Jacobs said: “Ryanair is Europe’s greenest/cleanest major airline with the youngest fleet and highest load factors.
“Our CO2 per passenger/km for June 2019 is 66g, almost half the rate of other flag carrier European airlines.
“We are also publishing our environmental taxes to dispel the myth that airlines pay no environmental taxes.”
