In Ireland, Reuters reported that governments will need to invest huge sums of taxpayers’ money if they want the fleets of the future to fly mainly on greener fuel, according to Aengus Kelly, CEO of the world’s number one lessor AerCap. “If governments want airlines to burn sustainable aviation fuel, they’re going to need to devote extraordinary sums of taxpayers’ money to make it happen,” Kelly said. Kelly said that given aviation accounts for an estimated 2-3% of global carbon emissions, the scale of investment could amount to “a poor use of a scarce resource”. “If we have a limited amount of funds, which every government does, we should put it where we get the biggest bang for our buck and I’m just not sure in aviation that it’s going to move the needle enough,” he said.
