Malaysia Aviation Group, the parent company of Malaysia Airlines, says it may introduce a green tax on passengers to help cover the high cost of sustainable aviation fuel (SAF). The airline is also renewing its fleet with fuel-efficient Airbus A330neo and Boeing 737 MAX jets, but SAF remains scarce and much more expensive than conventional jet fuel. SAF made from used cooking oil, waste fats and agricultural residues can cut around 65% of aviation emissions, but it currently accounts for less than 1% of global jet fuel use. Singapore has already announced a government-mandated green aviation tax starting January 2027, with charges varying by destination and cabin class. The airline says regulators, fuel suppliers and carriers need to work together to lower SAF costs, and warns that passing the full expense to passengers could weaken demand for air travel.
