In an effort to reduce emissions and encourage airlines to use sustainable aviation fuel, Singapore's parliament approved a bill on Tuesday that will impose a fixed fee on departing aircraft.
During a legislative discussion, Senior Minister of State for Transportation Sun Xueling stated that the charge would be given to the Civil Aviation Authority of Singapore, which will purchase and oversee sustainable aviation fuel.

With intentions to boost it further to between 3% and 5% by 2030, Singapore has set a goal to increase the use of sustainable aviation fuel to more than 1% by 2026. The country claims that this move won't result in a major increase in airfares.

All users of air transportation will be responsible for paying the fee; previous projections indicated that passengers on direct economy class flights would pay between S$3 ($2.30) and S$16, depending on the distance.
According to the International Air Transport Association, SAF can help the sector achieve net-zero carbon emissions by 2050 by reducing emissions by about 65%. The amount of green fuel being used worldwide is still quite small; this year, SAF is only estimated to account for 0.7% of aviation fuel, although air traffic is predicted to increase by 6%, increasing emissions.
