Qatar Airways’ chief executive said on Monday the industry’s net-zero 2050 target, which was set last year, would be difficult for airlines to achieve.

It is going to be “very challenging”, Akbar Al Baker told a press conference at the International Air Transport Associations (IATA) annual meeting of airline chiefs in Doha.

He said other stakeholders in the industry, including engine makers and oil companies, would need to contribute to the goal.
