Qatar Airways CEO suggests 2050 net-zero goal beyond reach

The head of Qatar Airways voiced scepticism on Tuesday over an aviation industry target of achieving net-zero emissions by 2050, citing inadequate supplies of Sustainable Aviation Fuel and alternative hydrogen designs in their infancy. "I don't think that we will be able to achieve net-zero emissions by 2050. Everybody's talking about it, but let us be realistic - there is not enough production of sustainable aviation fuel," CE Akbar Al Baker told the Qatar Economic Forum, organised by Bloomberg. The warning by one of the industry's most high-profile leaders come days before global airlines are due to discuss how to implement the climate pledge at an annual meeting of the IATA in Istanbul in June. Because aviation emissions are seen as hard to abate without radical technology, the main focus has been on "drop-in" fuels that can be placed in the existing generation of jet engines, like plant- or waste-based SAF and synthetic alternatives. "Really the only significant contributor by way of change in technology is Sustainable Aviation Fuel. That's the only thing that moves the needle between now and (2050)," Boeing CE Dave Calhoun told the same Doha event. In a stand-off with the energy industry over supplies available for aviation, airlines are concerned that a gap would hamper efforts to reach the target. There is also little consensus on who should pay to ramp up production, while some environmental groups say the plans are too modest. Airbus is promoting efforts to develop a small commercial airplane powered by hydrogen by 2035. Boeing's Calhoun said such technology would mature only in the second half of the century.<br/>
