GENEVA, Dec 6 Reuters The oil and gas sector and alternative fuel producers need to beef up efforts to produce greener aviation fuel to help airlines cut carbon emissions, the chief economist of global aviation industry body IATA said on Wednesday.

Aviation accounts for an estimated 23 of global carbon emissions and is not an easy industry to decarbonise compared with other forms of transport such as road travel.

Sustainable aviation fuel could reduce aviation emissions by up to 80 and is seen as the key green solution for the sector.

But it makes up only 0.2 of global jet fuel use, or about 500,000 metric tons of production, which is lower than the aviation industry expected, based on IATA figures. It also costs between three to five times more than traditional jet fuel.

Only 3 of global oil and gas capital budgets are invested into SAF production, while profit margins are much higher in the sector than in aviation, which is set to reach a 2.7 profit margin in 2024, IATA chief economist Marie Owens Thomsen told a media event in Geneva.

This clearly has to change, she said.

By 2050, 500 million metric tons of SAF will be needed to meet environmental targets, while by 2030, 63 million metric tons of SAF is set to be in production, based on an IATA forecast.

That investment burden cannot fall to airlines alone, IATA said.

Owens Thomsen estimated that airlines could spend up to 2.4 billion in 2024 on top of their regular costs to secure SAF.
