The cost of decarbonising air travel is likely to push up ticket prices and put some off flying, a group representing the UK aviation industry says.

Measures such as moving to higher-cost sustainable aviation fuel will "inevitably reduce passenger demand", according to Sustainable Aviation.

But it found people will "still want to fly" despite "slightly higher costs".

Annual passenger numbers are still expected to rise by nearly 250 million by 2050, it added.

Sustainable Aviation is an alliance of companies including airlines such as British Airways, airports such as Heathrow and manufacturers like Airbus.

It said that sustainable aviation fuel (Saf) would be a key part of the industry's "journey to net zero", accounting for at least three quarters of the fuel used in UK flights by 2050.
