Airlines not switching quickly enough to green jet fuel: Study

Most of the world's airlines are not doing enough to switch to sustainable jet fuel, according to a study by Brussels-based advocacy group Transport and Environment, which also found too little investment by oil producers in the

transition, reports Reuters.

The airline sector is calling for more production of the fuel, which can be made from materials such as

wood chips and used

cooking oil.

"Unfortunately, airlines at the moment are not on

the trajectory to have

meaningful emissions reduction because they're not buying enough

sustainable aviation fuel," Transport and Environment aviation policy manager Francesco Catte said.

As it stands, SAF makes up about 1 per cent of aviation fuel use on the global

market, which needs to increase for airlines to meet carbon emission reduction targets. The fuel can cost between two to five times more than

regular jet fuel.

A lack of investment by major oil players, who have the capital to build SAF

processing facilities, is

hampering the market's growth, the study says.
