DUBLIN (Reuters) - Ryanair is not sure it will reach its "very ambitious target" of powering 12.5% of its flights with sustainable aviation fuels by 2030, Group Chief Executive Michael O'Leary told CNBC television on Thursday.
But he said Ryanair, Europe's largest low-cost airline, was confident of reaching at least 10% and called for the European Union to set a similar target.
"The European Union has set a target of 5% of sustainable aviation fuel by 2030," O'Leary told the television station. "We think we can do better than that – I think we'll get to 10%."
"Whether we can get to 12.5%, I'm not sure, but I know if we don't invest in the research and that technology now, we certainly won't get there," O'Leary said, referring to a target Ryanair set in April.
O'Leary said he was concerned that increasing use of sustainable aviation fuels could have an upward impact on food prices.
